Basis Of Preparation [Abstract]
Basis of preparation [Text Block]	2. Basis of preparation (a) Statement of compliance: These consolidated financial statements have been prepared in accordance with International Financial Reporting Standards ("IFRS") as issued by the International Accounting Standards Board ("IASB") effective for the year ended December 31, 2023. The Board of Directors approved these consolidated financial statements on February 22, 2024. (b) Functional and presentation currency: Hudbay's consolidated financial statements are presented in US dollars, which is the Company's and all material subsidiaries' functional currency, except the Company's Manitoba and British Columbia business unit, which have a functional currency of Canadian dollars. All values are rounded to the nearest thousand ($000) except where otherwise indicated. (c) The consolidated financial statements have been prepared on the historical cost basis except for the following items in the consolidated balance sheets: - - - (d) The preparation of the consolidated financial statements in conformity with IFRS requires Hudbay to make judgements, estimates and assumptions that affect the application of accounting policies, reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and reported amounts of revenue and expenses during the reporting period. Actual results may differ from these estimates. Hudbay reviews these estimates and underlying assumptions on an ongoing basis, based on experience and other factors, including expectations of future events that the Company believes to be reasonable under the circumstances. Revisions to accounting estimates are recognized prospectively in the period in which the estimates are revised and in any future periods affected. The following are critical and significant judgements and estimates impacting the consolidated financial statements: - Indicators and testing of impairment (reversal of impairment) of non-financial assets (notes 3h, 3i, 13 an d 14) - - Mineral reserves and resources (notes 3g, 3k and 3i) - Changes in the mineral reserve or resource estimates may affect: - the carrying value of exploration and evaluation assets, capital works in progress, mining properties and plant and equipment, goodwill; - - - - - Property plant and equipment (notes 3h and 14) - - Tax provisions (notes 3m and 25 - Assaying utilized to determine revenue and recoverability of inventories (notes 3c and 3f) - - Decommissioning and restoration obligations (notes 3k and 22) - - Pension and other employee benefit (notes 3j, 23 and 24) - s - Valuation of an acquired business (note 5) - Valuation of assets in an asset acquisition (note 6) (e) Estimation uncertainty: The Company has assessed the broad implications of economic uncertainty including but not limited to inflation and higher interest rates, political instability in Peru and broadly as a result of global geopolitical instability, as well as the lingering impact of the novel coronavirus pandemic, on its consolidated financial statements. As at December 31, 2023, management has determined that the Company's ability to execute its medium and longer term plans and the economic viability of its assets, including the carrying value of its long-lived assets and inventory valuations, are not materially impacted. In making this judgement, the Company has assessed various criteria including, but not limited to, existing laws, regulations, orders, disruptions and potential disruptions in our supply chain, disruptions in the markets for our products, commodity prices and foreign exchange prices and the actions that the Company has taken at its operations to protect the health and safety of its workforce and local community.

Material accounting policies

Material accounting policies	Dec. 31, 2023
Significant Accounting Policies [Abstract]
Material accounting policies [Text Block]	3. Material accounting policies The accounting policies set out below have been applied consistently to all periods presented in these consolidated financial statements and by all Hudbay's entities. (a) Intercompany balances and transactions are eliminated upon consolidation. When a Hudbay entity transacts with an associate or jointly controlled entity of the Company, unrealized profits and losses are eliminated to the extent of Hudbay's interest in the relevant associate or joint venture. The accounting policies of Hudbay's entities are changed when necessary to align them with the policies adopted by the Company. Subsidiaries A subsidiary is an entity controlled by Hudbay. The financial statements of subsidiaries are included in the consolidated financial statements from the date that control commences until the date that control ceases. Non-controlling interest Non-controlling interest in subsidiaries are identified separately from the Company's equity in the subsidiaries. The interest of non-controlling shareholders may be initially measured either at fair value or at the non-controlling interest proportionate share of the fair value of the acquiree's identifiable net assets. The choice of measurement basis is made on an acquisition-by-acquisition basis. Subsequent to acquisition, the carrying amount of non-controlling interest is the amount of that interest at initial recognition plus the non-controlling interest share of subsequent changes in equity. Total comprehensive income is attributed to non-controlling interest even if this results in the non-controlling interest having a deficit balance. Business combinations and goodwill Should Hudbay make an acquisition, it first determines whether the assets acquired and liabilities assumed constitute a business, in which case the acquisition requires accounting as a business combination. Management applies judgement in determining whether the acquiree is capable of being conducted and managed for the purpose of providing a return, considering the inputs of the acquiree and processes applied to those inputs that have the ability to create outputs. Hudbay applies the acquisition method of accounting to business combinations, whereby the goodwill is measured at the acquisition date as the fair value of the consideration transferred including the recognized amount of any non-controlling interest in the acquiree. When the excess is negative, a bargain purchase gain is recognized immediately in the consolidated income statements. The assessment of fair values on acquisition includes those mineral reserves and resources that are able to be reliably measured. In determining these fair values, management must also apply judgement in areas including future cash flows, metal prices, exchange rates and appropriate discount rates. Changes in such estimates and assumptions could result in significant differences in the amount of goodwill recognized. The consideration transferred is the aggregate of the fair values, at the date of the acquisition, of the sum of the assets transferred, the liabilities incurred or assumed, and the equity instruments issued by the acquirer in exchange for control of the acquiree. Acquisition-related costs are recognized in the consolidated income statements as incurred, unless they relate to issuance of debt or equity securities. Where applicable, the consideration transferred includes any asset or liability resulting from a contingent consideration arrangement and measured at its acquisition date fair value. Subsequent changes in such fair values are adjusted against the cost of acquisition where they qualify as measurement period adjustments. All other subsequent changes in the fair value of contingent consideration classified as an asset or liability are accounted for in accordance with relevant IFRS. Changes in the fair value of contingent consideration classified as equity are not recognized. Where a business combination is achieved in stages, the Company's previously held interest in the acquired entity are remeasured to fair value at the acquisition date, which is the date Hudbay attains control, and any resulting gain or loss is recognized in the consolidated income statements. Amounts previously recognized in other comprehensive income ("OCI") related to interest in the acquiree prior to the acquisition date are reclassified to the consolidated income statements, where such treatment would be appropriate if that interest were disposed of. After initial recognition, goodwill is measured at cost less any accumulated impairment losses. For the purpose of impairment testing, goodwill acquired in a business combination is, from the acquisition date, allocated to each of Hudbay's CGUs that are expected to benefit from the synergies of the combination, irrespective of whether other assets or liabilities of the acquiree are assigned to those units. Goodwill is allocated to the lowest level at which it is monitored for internal management purposes and is not larger than an operating segment before aggregation. Where goodwill forms part of a CGU and part of the operation within that unit is disposed of, the goodwill associated with the disposed operation is included in the determination of any gain or loss on disposal. Goodwill is not amortized and is tested for impairment annually and whenever there is an indication of impairment. If any such indication exists, the recoverable amount of the CGU is estimated in order to determine the extent of the impairment, if any. The recoverable amount is determined as the higher of fair value less direct costs to sell and the CGU's value in use. When the recoverable amount of the CGU is less than the carrying amount of that CGU, the impairment loss is allocated to reduce the carrying amount of any goodwill allocated to that CGU first, and then to the other assets of that CGU on a pro-rata basis of the carrying amount of each asset in the CGU. An impairment loss in respect of goodwill is not reversed. Fair value for mineral interest and related goodwill is generally determined as the present value of the estimated future cash flows expected to arise from the continued use of the asset, including any expansion prospects, and its eventual disposal, using assumptions that an independent market participant may take into account. Value in use is determined as the present value of the estimated future cash flows expected to arise from the continued use of the asset in its present form and its eventual disposal. Value in use is determined by applying assumptions specific to Hudbay's continued use and cannot take into account future development. The weighted average cost of capital of Hudbay or comparable market participants is used as a starting point for determining the discount rates, with appropriate adjustments for the risk profile of the countries in which the individual CGUs operate and the specific risks related to the development of the project. Where the asset does not generate cash flows that are independent of other assets, Hudbay estimates the recoverable amount of the CGU to which the asset belongs. If the carrying amount of an asset or CGU exceeds its recoverable amount, the carrying amount of the asset or CGU is reduced to its recoverable amount. An impairment loss is recognized as an expense in the consolidated income statements. (b) Translation of foreign currencies: Management determines the functional currency of each Hudbay entity as the currency of the primary economic environment in which the entity operates. Foreign currency transactions Transactions in foreign currencies are translated to the respective functional currencies of Hudbay's entities at exchange rates in effect at the transaction dates. At the end of each reporting period, monetary assets and liabilities denominated in foreign currencies are translated to the functional currency using the closing exchange rate. Non-monetary assets and liabilities measured at fair value are translated using the exchange rates at the date when fair value was determined. Non-monetary assets and liabilities measured at historical cost in a foreign currency are translated using exchange rates that were in effect at the transaction dates. The same translations are applied when an entity prepares its financial statements from books and records maintained in a currency other than its functional currency, except revenue and expenses may be translated at monthly average exchange rates that approximate those in effect at the transaction dates. Foreign currency gains and losses arising on period-end revaluations are recognized in the consolidated income statements, except for a financial liability designated as a hedge of a net investment in a foreign operation, or qualifying cash flow hedges, which are recognized in OCI. Foreign operations For the purpose of the consolidated financial statements, assets and liabilities of Hudbay's entities that have functional currencies other than the US dollar are translated to US dollars at the reporting date using the closing exchange rate. Revenue and expenses are translated at monthly average exchange rates that approximate those in effect at the transaction dates. Differences arising from these foreign currency translations are recognized in OCI and presented within equity in the foreign currency translation reserve. When a foreign operation is disposed, the relevant exchange differences accumulated in the foreign currency translation reserve are transferred to the consolidated income statements as part of the profit or loss on disposal. On the partial disposal of a subsidiary that includes a foreign operation, the relevant proportion of such amount is reattributed to non-controlling interest. On disposal of a partial investment in an associate or joint venture that includes a foreign operation while retaining significant influence or joint control, the relevant proportion is reclassified to profit or loss. Net investment in a foreign operation Foreign currency gains and losses arising on translation of a monetary item receivable from or payable to a foreign operation for which settlement is neither planned nor likely to occur in the foreseeable future are considered to form part of a net investment in the foreign operation. Such gains and losses are recognized in OCI and presented within equity in the foreign currency translation reserve. (c) Revenue recognition: Revenue from the sale of goods is measured at the fair value of the consideration received or receivable, net of treatment and refining charges. Revenue from the sale of by-products is included within revenue. Revenue is recognized when control of the goods sold has been transferred to the customer. Control is deemed to have passed to the customer when significant risk and reward of the product has passed to the customer, Hudbay has a present right to payment, and physical possession of the product has been transferred to the customer. Sales of doré are recorded when a trade confirmation is duly signed and executed between Hudbay and the end purchaser. Sale of concentrate and finished zinc frequently occur under the following terms, and management has assessed these terms in order to determine timing of transfer of control and revenue recognition as generally outlined in the following table. Incoterms used by Hudbay Revenue recognized when goods: Cost, Insurance and Freight (CIF) Are loaded on board the vessel Free on Board (FOB) Are loaded on board the vessel Delivered at place (DAP) Arrive at the named place of destination Delivered at terminal (DAT) Arrive at the named place of destination Free Carrier (FCA) Arrive at the named place of delivery Sales of copper and zinc concentrate and certain other products are provisionally priced. For these contracts, sales prices are subject to final adjustment at the end of a future period after shipment, based on quoted market prices during the quotational period specified in the contract. Revenue is recognized when the above criteria are achieved, using weight and assay results and forward market prices to estimate the fair value of the total consideration receivable. Therefore, revenue is initially recorded based on an initial provisional invoice. Subsequently, at each reporting date, until the provisionally priced sale is finalized, sales receivables are marked to market, with adjustments (both gains and losses) recorded within revenue separately as "Pricing and volume adjustments" in the notes to the consolidated financial statements and in trade and other receivables on the consolidated balance sheets. As per IFRS 15 Revenue from contracts with customers Financial Instruments Hudbay only includes in the transaction price an amount which is not highly likely to be subject to significant subsequent revenue reversal. Within sales contracts with customers, separate performance obligations may arise pertaining to the shipping of goods sold. If applicable, costs and the transaction price are allocated on a relative standalone selling basis to any separate performance obligations and are recognized over the period of time the goods sold are shipped, on a gross basis. Hudbay recognizes deferred revenue in the event it receives payments from customers before a sale meets criteria for revenue recognition. Precious metals stream contracts, which at inception of the contract are determined that they can be satisfied through the delivery of Hudbay's own production of non-financial items (i.e. gold and silver credits) rather than cash or other financial assets, are accounted for as deferred revenue. If settlement with Hudbay's own production of gold and silver is not possible, the stream transaction is recognized as a financial liability since settlement may require a cash payment. This would cause a change to the accounting treatment, resulting in the revaluation of the agreement to the fair value through the consolidated income statements on a recurring basis. Deferred revenue associated with precious metals stream contracts are subject to variable consideration and contain a significant financing component since funds were received in advance of the delivery of concentrate. When a significant financing component is recognized, finance expense will be higher and revenues will be higher as the larger deferred revenue balance is amortized to revenues. A market-based discount rate is utilized at the inception of each of the respective stream agreements to determine a discount rate for computing the interest charges for the significant financing component of the deferred revenue balance. As product is delivered, the deferred revenue amount including accreted interest will be drawn down. The draw down rate requires the use of proven and probable reserves and certain resources in the calculation that are beyond proven and probable reserves which management is reasonably confident will be transferable to reserves. Key estimates used in determining the significant financing component include the discount rate and the reserve and resources assumed for conversion. (d) Cost of sales: Cost of sales consists of those costs previously included in the measurement of inventory sold during the period, as well as certain costs not included in the measurement of inventory, such as the cost of warehousing and distribution to customers, provisional pricing adjustments related to purchased concentrates, profit sharing, royalty payments, share-based compensation expense and other indirect expenses related to producing operations. Cost of sales also include non-cash net realizable value adjustments to inventory, one-time adjustments related to overheads incurred when not operating at normal capacity and one-time labour charges related to facilitating the production of inventories for past service pension costs, curtailment gains and severance. (e) Cash and cash equivalents: Cash and cash equivalents include cash, demand deposits and short-term, highly liquid investments that are readily convertible to known amounts of cash and are subject to an insignificant risk of changes in value. Cash equivalents have maturities of three months or less at the date of acquisition. Interest earned is included in finance income on the consolidated income statements and in investing activities on the consolidated statements of cash flows. Amounts that are restricted from being used for at least twelve months after the reporting date or are not available for general disbursement, like a debt service account are classified as non-current assets and presented in other financial assets on the consolidated balance sheets. Changes in restricted cash balances are classified as investing or financing activities on the consolidated statements of cash flows. (f) Inventories: Inventories consist of stockpiles, finished goods inventory (concentrates and metals), materials and supplies. Concentrates, doré, metals and all other saleable products are valued at the lower of cost and estimated net realizable value. Net realizable value represents the estimated selling price for inventories less all estimated direct and indirect costs of completion and costs necessary to make the sale. Where the net realizable value is less than cost, the difference is charged to the consolidated income statements as an impairment charge in cost of sales. Costs associated with stripping activities in an open pit mine are capitalized to inventory and recorded through cost of sales unless the stripping activity can be shown to improve access to further quantities of ore that will be mined in future periods, in which case, the stripping costs are capitalized to property, plant and equipment. Cost of production of concentrate inventory is determined on a weighted average cost basis and the cost of production of finished metal inventory is determined using the first in first out basis. The cost of production includes direct costs associated with conversion of production inventory based on normal production capacity: material, labour, contractor expenses, purchased concentrates, and an attributable portion of production overheads and depreciation of all property, plant and equipment involved with the mining and production process. Hudbay measures in-process inventories based on assays of material received at metallurgical plants and estimates of recoveries in the production processes. Due to significant uncertainty associated with volume and metal content, immaterial costs are not allocated to routine operating levels of stockpiled ore. Estimates and judgements are required to assess the nature of any significant changes to levels of ore stockpiles and determining whether allocation of costs is required. Supplies are valued at the lower of average cost and net realizable value. (g) Exploration and evaluation expenditures: Exploration and evaluation activity begins when Hudbay obtains legal rights to explore a specific area and involves the search for mineral reserves, the determination of technical feasibility, and the assessment of commercial viability of an identified resource. Expenditures incurred in the exploration and evaluation phase include the cost of acquiring interest in mineral rights, licenses and properties and the costs of Hudbay's exploration activities, such as researching and analyzing existing exploration data, gathering data through geological studies, exploratory drilling, trenching, sampling, and certain feasibility studies. Hudbay expenses the cost of its exploration and evaluation activities and capitalizes the cost of acquiring interest in mineral rights, licenses and properties in business combinations, asset acquisitions or option agreements. Amounts capitalized are recognized as exploration and evaluation assets and presented in property, plant and equipment. Exploration and evaluation assets acquired as a result of an asset acquisition or option agreement are initially recognized at cost, and those acquired in a business combination are recognized at fair value on the acquisition date. They are subsequently carried at cost less accumulated impairment. No depreciation is charged during the exploration and evaluation phase. Hudbay expenses the cost of subsequent exploration and evaluation activity related to acquired exploration and evaluation assets. Cash flows associated with acquiring exploration and evaluation assets are classified as investing activities in the consolidated statements of cash flows; those associated with exploration and evaluation expenses are classified as operating activities. Judgement is required in determining whether the respective costs are eligible for capitalization where applicable, and whether they are likely to be recoverable, which may be based on assumptions about future events and circumstances. Estimates and assumptions made may change if new information becomes available. Hudbay monitors exploration and evaluation assets for factors that may indicate their carrying amounts are not recoverable. If such indicators are identified, the Company tests the exploration and evaluation assets or their CGUs, as applicable, for impairment. Hudbay also tests for impairment when assets reach the end of the exploration and evaluation phase. Exploration and evaluation assets are transferred to capital works in progress within property, plant and equipment once the Company determines that probable future economic benefits will be generated as a result of the expenditures. Hudbay's determination of probable future economic benefit is based on management's evaluation of the technical feasibility and commercial viability of the geological properties of a given ore body based on information obtained through evaluation activities, including metallurgical testing, resource and reserve estimates and the economic assessment of whether the ore body can be mined economically. Tools that may be used to determine this include a preliminary feasibility study, confidence in converting resources into reserves and the probability that the property could be developed into a mine site. At that time, the property is considered to enter the development phase, and subsequent evaluation costs are capitalized. (h) Property, plant and equipment: Hudbay measures items of property, plant and equipment at cost less accumulated depreciation and any accumulated impairment losses. The initial cost of an item of property, plant and equipment includes its purchase price or construction costs, including import duties and non-refundable purchase taxes, any costs directly attributable to bringing the asset into operation, and for qualifying assets, borrowing costs. The initial cost of property, plant and equipment also includes the initial estimate of the cost of dismantling and removing the item and restoring the site on which it is located, the obligation which Hudbay incurs either when the item is acquired or as a consequence of having used the item during a particular period for purposes other than to produce inventories during that period. Capitalization of costs ceases once an asset is in the location and condition necessary for it to be capable of operating in the manner intended by management. At this time, depreciation commences. For a new mine, this occurs upon commencement of commercial production. Any revenues less cost to produce, earned prior to commencement of commercial production, are included in the consolidated income statements. Carrying amounts of property, plant and equipment, including right-of-use ("ROU") assets, are depreciated to their estimated residual value over the estimated useful lives of the assets or the estimated life of the related mine or plant, if shorter. Where components of an asset have different useful lives, depreciation is calculated on each separate component. Components may be physical or non-physical, including the cost of regular major inspections and overhauls required in order to continue operating an item of property, plant and equipment. Certain items of property, plant and equipment are depreciated on a unit-of-production basis. The unit-of-production method is based on proven and probable tonnes of ore reserves. There are numerous uncertainties inherent in estimating ore reserves, and assumptions that were valid at the reporting date may change when new information becomes available. The actual volume of ore extracted and any changes in these assumptions could affect prospective depreciation rates and carrying values. The carrying amount of an item of property, plant and equipment is derecognized on disposal or when no future economic benefits are expected from its use or disposal. Upon derecognition of an item of property, plant and equipment, the difference between its carrying value and net sales proceeds, if any, is presented as a gain or loss in other operating income or expense in the consolidated income statements. i. Capital works in progress consist of items of property, plant and equipment in the course of construction or mineral properties in the course of development, including those transferred upon completion of the exploration and evaluation phase. On completion of construction or development, costs are transferred to plant and equipment and/or mining properties as appropriate. Capital works in progress are not depreciated. ii. Mining properties consist of costs transferred from capital works in progress when a mining property reaches commercial production, costs of subsequent mine and exploration development, and acquired mining properties in the production stage. Mining properties include costs directly attributable to bringing a mineral asset into the state where it is capable of operating in the manner intended by management and includes such costs as the cost of shafts, ramps, track haulage drifts, ancillary drifts, pumps, electrical substations, refuge stations, ventilation raises, permanent manways, and ore and waste pass raises. The determination of development costs to be capitalized during the production stage of a mine operation requires the use of judgements and estimates such as estimates of tonnes of waste to be removed over the life of the mining area and economically recoverable reserves extracted as a result. A mining property is considered to be capable of operating in a manner intended by management when it commences commercial production based on pre-established criteria. Upon commencement of commercial production, a mining property is depreciated on a unit-of-production method. Unit-of-production depreciation rates are determined based on the related proven and probable mineral reserves and associated future development costs. Subsequent mine development costs are capitalized to the extent they are incurred in order to access reserves mineable over more than one year. Ongoing maintenance and development expenditures are expensed as incurred and included in cost of sales in profit or loss. These include ore stope access drifts, footwall and hangingwall drifts in stopes, drawpoints, drill drifts, sublevels, slots, drill raises, stope manway access raises and definition diamond drilling. iii. Plant and equipment consists of buildings and fixtures, surface and underground fixed and mobile equipment and assets under lease. Plant and equipment are depreciated on either unit-of-production or straight-line basis based on factors including the production life of assets and mineable reserves. In general, mining assets are depreciated using a unit-of-production method; equipment is depreciated using the straight-line method, based on the shorter of its useful life and that of the related mine or facility; and plants are depreciated using the straight-line method, with useful lives limited by those of related mining assets. iv. At inception of a contract, Hudbay assesses whether a contract is, or contains, a lease. A contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. The Company assesses the following criteria in the determination of whether a contract conveys the right to control the use of an identified asset: • • • ▪ ▪ The Company recognizes a ROU asset and lease liability at the lease commencement date. The initial measurement of the ROU asset is on a present value basis. This is based on the calculated lease liability plus any initial direct costs incurred, an estimate of removal or restoration costs, and any payments made prior to commencement of the lease less any lease incentives received. The right of use asset is subsequently depreciated using the straight-line method from the commencement date to the earlier of the end of the useful life of the right-of-use asset or the end of the lease term. The estimated useful lives of the right-of-use assets are determined on the same basis as those of property and equipment. In addition, the right-of-use asset is periodically reduced by impairment losses, if any, and adjusted for certain remeasurements of the lease liability. The lease liability is measured at the present value of the lease payments that are yet to be paid at the commencement date, discounted using the interest rate implicit in the lease or, if that rate cannot be easily determined, Hudbay's incremental borrowing rate. Generally, the Company uses its incremental borrowing rate as the discount rate for applicable leases. Lease payments included in the measurement of the lease liability comprise fixed payments including in substance fixed payments and variable payments that depend on an index or rate, amounts expected to be payable under a residual value guarantee and the additional costs Hudbay reasonably expects to incur due to purchase options, extension options and termination options reasonably expected to be exercised. The lease liability is measured at amortized cost using the effective interest method. It is remeasured when there is a change in the expected future cash flows of a leasing contract either due to a change in index or rate, or due to a change in terms of the contract. When the lease liability is remeasured in this way, a corresponding adjustment is made to the carrying amount of the right-of-use asset, or is recorded in profit or loss if the carrying amount of the right-of-use asset is zero. Hudbay has elected not to separate non-lease components and account for the lease and non-lease components as a single lease component for lease contracts of all asset classes. The Company has elected not to recognize ROU assets and lease liabilities for short-term leases of machinery that have a lease term of 12 months or less and leases of low-value assets. Hudbay recognizes the lease payments associated with these leases as an expense on a straight-line basis over the lease term. Hudbay does not enter into transactions where the Company acts as a lessor. The incremental borrowing rate used for new ROU leases is a key management judgement. v. • • • • ◦ ◦ • Hudbay reviews its depreciation methods, remaining useful lives and residual values at least annually and accounts for changes in estimates prospectively. vi. Commercial production is the level of activities intended by management for a mine, or a mine and mill complex, to be capable of operating in the manner intended by management. Hudbay considers a range of factors when determining the level of activity that represents commercial production for a particular project, including a predetermined percentage of design capacity for the mine and mill; achievement of continuous production, ramp-ups, or other output; or specific factors such as recoveries, grades, or inventory build-ups. In a phased mining approach, management may consider achievement of specific milestones at each phase of completion. In a non-phased mining approach, management considers average actual metrics that are at least 60% of average design capacity or plan over a continuous period. Management assesses the operation's ability to sustain production over a period of approximately one to three months, depending on the complexity related to the stability of continuous operation. Commercial production is considered to have commenced, and depreciation expense is recognized, at the beginning of the month after criteria have been met. vii. The Company capitalizes borrowing costs that are directly attributable to the acquisition, construction or production of qualifying assets, which are assets that necessarily take a substantial period of time, generally one year or more, to get ready for their intended use or sale. Capitalization of borrowing costs ceases once the qualifying assets

Disclosure of changes in accounting estimates [abstract]
New standards [Text Block]	4. New standards New standards and interpretations adopted (a) Amendment to IAS 1 - Presentation of Financial Statements and IFRS Practice Statement 2 Making Materiality Judgements The amendments to IAS 1 help companies provide useful accounting policy disclosures. The adoption of the new standard effective January 1, 2023 did not impact the consolidated financial statements of the Company. (b) In May 2023, the IASB issued International Tax Reform-Pillar Two Model Rules, which amended IAS 12, Income Taxes, to introduce a temporary exception to the requirements to recognize and disclose information about deferred tax assets and liabilities related to Pillar Two income taxes, and targeted disclosure requirements for affected entities. The relief is effective immediately upon issuance of the amendments while the targeted disclosure requirements are effective for annual reporting periods beginning on or after January 1, 2023. The Company has applied the exception and is currently assessing the impact of the disclosure requirements on its consolidated financial statements. Based on the existing revenue thresholds applicable under the Pillar Two Model Rules, the Company is within the scope of the rules as gross revenues exceed 750,000 Euros. As the legislation has not been enacted or substantively enacted in Canada, the Company continues to evaluate the impact of the legislation on its consolidated financing statements. New standards issued but not yet effective (c) Amendment to IAS 1 - Presentation of Financial Statements The amendments to IAS 1 clarify that only covenants with which an entity is required to comply on or before the reporting date affect the classification of a liability as current or non-current. In addition, an entity has to disclose information in the notes that enables users of financial statements to understand the risk that non-current liabilities with covenants could become repayable within twelve months. Classification is unaffected by the expectations that the entity will exercise its right to defer settlement of a liability. Lastly, the amendments clarify that settlement refers to the transfer to the counterparty of cash, equity instruments, other assets. The amendments are effective for annual periods beginning on or after January 1, 2024. Earlier application is permitted. The Company is still assessing the impact of adoption of this amendment on its consolidated financial statements.

Disclosure of detailed information about business combination [line items]
Acquisition of Copper Mountain Mining Corporation [Text Block]	5. Acquisition of Copper Mountain Mining Corporation On June 20, 2023, Hudbay acquired all of the issued and outstanding common shares of Copper Mountain, as part of a court-approved plan of arrangement. At the time, Copper Mountain held 75% of CMBC, the entity that owns 100% of the Copper Mountain mine. MMC owns the remaining 25% interest in CMBC as a non-controlling interest. As described in Note 1 above, on January 1, 2024, Hudbay amalgamated with Copper Mountain and continued as Hudbay Minerals Inc. Following the amalgamation, the Company directly holds a 75% interest in CMBC. As a result of the acquisition, Hudbay obtained control of Copper Mountain on June 20, 2023. Management determined that the assets and processes comprised a business and therefore accounted for the transaction as a business combination, using the acquisition method of accounting. Consideration transferred: The purchase consideration paid by Hudbay was for 100% of the net assets of Copper Mountain and their 100% owned subsidiaries ("100% owned entities") and a 75% ownership in CMBC. The aggregate purchase consideration for the acquired assets, net of the liabilities assumed is as follows: Equity instruments (84,165,617 common shares of Hudbay) $ 436,687 Cash 3,794 Consideration transferred - June 20, 2023 $ 440,481 The fair value of the common shares issued was based on Hudbay's listed share price of C$6.87 at the June 20, 2023 acquisition date. Immediately prior to the acquisition, Copper Mountain settled its outstanding restricted share units and performance share units through the issuance of shares and settled its stock options for replacement Hudbay options that were immediately settled in cash. Hudbay incurred acquisition related costs of $6,932 during the year ended December 31, 2023, mainly relating to external legal and advisory fees and due diligence costs, which were recorded in other expense in the consolidated income statements. In addition, Hudbay incurred share issuance costs of $188 and presented these as a deduction from share capital. Identifiable assets acquired and liabilities assumed: The fair value of the net assets was determined using a combination of market, income and cost methods. The fair value of the non-controlling interest was then computed at a 25% of the equity interest in CMBC. The following presents the allocation of the purchase price, resulting in recognized fair value amounts of identifiable assets acquired and liabilities assumed as follows: Fair value of net assets acquired / (liabilities) assumed Preliminary Adjustment Final Cash and cash equivalent $ 14,483 $ - $ 14,483 Trade and other receivables 19,110 - 19,110 Inventories 47,875 - 47,875 Prepaid expenses 3,096 - 3,096 Other financial assets 8,495 - 8,495 Property, plant and equipment 434,419 402 434,821 Mineral properties 383,000 (14,000 ) 369,000 Inventories - low grade stockpile 6,000 - 6,000 Trade and other payables (77,111 ) - (77,111 ) Advances from Hudbay (3,421 ) - (3,421 ) Lease liabilities (44,167 ) 9,550 (34,617 ) Other financial liabilities - (9,550 ) (9,550 ) Long-term debt (144,981 ) - (144,981 ) Environmental and other provisions (12,702 ) - (12,702 ) Deferred tax liabilities (153,208 ) 4,962 (148,246 ) Total fair value of net identifiable assets acquired $ 480,888 $ (8,636 ) $ 472,252 The fair values allocated to assets acquired and liabilities assumed previously reported as at June 30, 2023 was based on the preliminary estimates at the acquisition date and subject to change for up to one year from the acquisition date. As of the date of the audited annual consolidated financial statements, the allocation of purchase price with respect to the fair value increment of assets acquired and liabilities assumed has been updated to reflect new information obtained that existed at the acquisition date. The Company has finalized its full assessment of the fair value of net assets acquired. The fair values of mineral properties, low grade stockpile and other property, plant and equipment have been determined based on an independent valuation, using a combination of market, income and cost methods. In particular, the fair values of the mineral properties and low grade stockpile have been calculated using significant judgements and estimates. Trade receivables acquired as part of the acquisition have a fair value of $8,764 which is equal to their gross contractual value. Other receivables acquired have a fair value of $10,346 which is equal to their gross contractual value. Trade and other receivables are expected to be collected during the next 12 months. Hudbay provided advances to Copper Mountain prior to the acquisition date, which have been recorded as a purchaser loan. Hudbay recognized goodwill as a result of the acquisition as follows: Preliminary Adjustment Final Total consideration transferred $ 440,481 $ - $ 440,481 Non-controlling interest 106,976 - 106,976 Less: value of net identifiable assets acquired (480,888 ) 8,636 (472,252 ) Goodwill upon acquisition at June 20, 2023 $ 66,569 $ 8,636 $ 75,205 The goodwill balance arose from the requirement to record deferred income tax liabilities measured at the tax effect of the difference between the fair values of the assets acquired and liabilities assumed and their tax bases. None of the goodwill recognized is expected to be deductible for income tax purposes. The results of operations have been consolidated with those of the Company from the date of acquisition and included in the British Columbia operating segment. Had the business combination been affected at January 1, 2023, revenue and profit of the combined entity would have been $1,824,713 and $27,406 respectively. The revenue and net profit contributed from the acquisition of Copper Mountain has been $ 165,438 $ 13,376

Acquisition of Rockcliff Metals Corporation [Text Block]	6. Acquisition of Rockcliff Metals Corporation On September 14, 2023, Hudbay acquired all of the issued and outstanding common shares of Rockcliff, as part of a court-approved plan of arrangement. In doing so, Hudbay obtained control of Rockcliff on September 14, 2023. As described in Note 1 above, on January 1, 2024, Hudbay amalgamated with Rockcliff and continued as Hudbay Minerals Inc. Following the amalgamation, the Company directly holds all of Rockcliff's mineral properties and other assets. Management determined that substantially all of the fair value of the gross assets acquired is concentrated in the Talbot exploration property and therefore accounted for the transaction as an asset acquisition. The purchase consideration paid was 2,675,324 Hudbay common shares and 517,460 Hudbay warrants. For asset acquisitions settled with equity, entities are required to record the net assets acquired based on the fair value of the assets received in exchange for the equity issued, unless that fair value cannot be estimated reliably. Hudbay incurred acquisition related costs of $518 during the third quarter of 2023, mainly relating to external legal and advisory fees and due diligence costs, which were capitalized and included as a cost of acquiring the net assets. The fair value of the net assets acquired was determined using a combination of income and cost methods. In particular, the fair values of the exploration property have been calculated using significant judgements and estimates. The following presents the fair value amounts of identifiable assets acquired and liabilities assumed: Fair value of net assets acquired / (liabilities) assumed Cash and cash equivalents $ 270 Accounts receivable and prepaid expenses 98 Property, plant & equipment 33 Exploration property 14,198 Accounts payable and accrued liabilities (305 ) Advance from Hudbay (548 ) Total fair value of net identifiable assets acquired $ 13,746

Gold and silver stream revenue can be subject to cumulative adjustments when the amount of precious metals to be delivered under the contract changes. As a result of changes in the Company's mineral reserve and resource estimate in the first quarter of 2023, the amortization rate by which deferred revenue is drawn down into income was adjusted and, as required, a variable consideration adjustment was made for all prior year stream revenues since the stream agreement inception date. This variable consideration adjustment for the year ended December 31, 2023 resulted in an increase of revenue of $4,885 (b) Depreciation of property, plant and equipment and amortization of intangible assets are reflected in the consolidated income statements as follows: Year ended December 31, 2023 2022 Cost of sales $ 391,657 $ 337,615 Selling and administrative expenses 1,411 1,448 $ 393,068 $ 339,063 (c) Share-based compensation expenses are reflected in the consolidated income statements as follows: Cash-settled Total share- based compensation expense RSUs DSUs PSUs Stock options Year ended December 31, 2023 Cost of sales $ 589 $ - $ - $ - $ 589 Selling and administrative 2,076 1,717 621 2,137 6,551 Other expenses 217 - - - 217 $ 2,882 $ 1,717 $ 621 $ 2,137 $ 7,357 Year ended December 31, 2022 Cost of sales $ 420 $ - $ - $ - $ 420 Selling and administrative 1,541 (849 ) (1,011 ) $ 1,848 1,529 Other expenses 115 - - - 115 $ 2,076 $ (849 ) $ (1,011 ) $ 1,848 $ 2,064 During the year ended December 31, 2023, the Company granted 801,661 stock options (year ended December 31, 2022 - 602,614).

(g) As a result of the Copper World Complex preliminary economic assessment released in June 2022, which contemplates the mining of the Copper World deposits and the Rosemont deposit in a two-phase mine plan, it was determined that certain capitalized costs and assets associated with the previous stand-alone development plan for the Rosemont deposit are no longer recoverable. As a result, during the second quarter of 2022, the Company recognized a pre-tax impairment loss of $94,956 related to these assets. The impairment loss was determined based on the specific identification of assets that are not expected to be recoverable under the Copper World Complex PEA. The Company presented the impairment losses within the Arizona segment in note 35. The fair value measurements used in the determination of impairment charges are categorized as level 2 based on the degree to which inputs are observable and have a significant effect on the recorded fair value.

Other assets represent the carrying value of certain future community costs that relate to agreements with communities near the Peru operations which allow Hudbay to extract or explore minerals over the useful life of Peru operations. The liability remaining for these costs is recorded in agreements with communities recorded at amortized cost (note 17). Amortization of the carrying amount is recorded in the consolidated income statements within other expenses (note 7e) or exploration expenses, depending on the nature of the agreement. Intangibles mainly represent computer software costs.

Goodwill [Text Block]	13. Goodwill The following table summarizes changes in goodwill: Balance, January 1, 2023 $ - Goodwill recognized on business combination (note 5) 75,205 Effects of changes in foreign exchange 80 Balance, December 31, 2023 $ 75,285 Goodwill resulted from purchase price allocation associated with the Copper Mountain acquisition (note 5). As of December 31, 2023 all goodwill relates to the British Columbia CGU. Goodwill is tested for impairment annually on December 31 or when circumstances indicate that the carrying value may not be recoverable. Goodwill impairment is determined by assessing the recoverable amount of the CGU. For the impairment test completed at December 31, 2023, Fair Value Less Cost of Disposal, ("FVLCD") was used to determine the recoverable amount since it is higher than value in use. FVLCD was calculated using discounted after-tax cash flows based on cash flow projections and assumptions in Hudbay's most current LOM. The fair value measurement in its entirety is categorized as Level 3 based on the degree to which fair value inputs are observable and have a significant effect on the recorded fair value. LOM plans are based on optimized mine and processing plans and the assessment of capital expenditure requirements of a mine site. Management used judgement in determining estimates and assumptions with respect to discount rates, future production levels including amounts of recoverable reserves, resources and exploration potential, operating and capital costs, long-term metal prices, value of mineral resources not included in the LOM plan and future foreign exchange rates. Metal pricing assumptions were based on consensus forecast pricing, and the discount rates were based on a weighted average cost of capital, adjusted for country risk and other risks specific to the CGU. Cash flows were projected through to 2043. Changes in any of the assumptions or estimates used in determining the fair values could impact the impairment analysis. The discount rate was based on the CGU's weighted average cost of capital, of which the two main components are the cost of equity and the after-tax cost of debt. Cost of equity was calculated based on the capital asset pricing model, incorporating the risk-free rate of return based on the Canadian Government's marketable bond yields as at the valuation date, the Company's beta coefficient adjustment to the market equity risk premium based on the volatility of the Company's return in relation to that of a comparable market portfolio, plus a country risk premium, size premium and company-specific risk factor. Cost of debt was determined by applying an appropriate market indication of the Company's borrowing capabilities and the corporate income tax rate applicable to the segment's jurisdiction. A real discount rate of 7.25% for the British Columbia CGU was used to calculate the estimated after- tax discounted future net cash flows, commensurate with its individual estimated level of risk. Commodity prices used in the impairment assessment were determined by reference to external market participant sources. The key commodity price for this assessment is the price of copper. The cash flow calculations were based on estimates of future production levels applying forecasts for metal prices, which included forecasts for each year from 2024 to 2028 and long-term forecasts for years beginning in 2029. The cash flow calculations utilized a copper price of $3.75/lb starting in 2024. The cash flow calculations utilized a long-term copper price of $4.00/lb, and capital, operating and reclamation costs based on the most current LOM plans. A value of $311,000 was utilized to estimate the value of mineral resources not included in the LOM plan. Expected future cash flows used to determine the FVLCD in the impairment test are inherently uncertain and could materially change over time. The Company has conducted an analysis of the sensitivity of the impairment test to changes in the key assumptions used to determine the recoverable amount for the CGUs to which goodwill is allocated. Management believes that any reasonably possible change in the key assumptions on which the recoverable amount is based would not cause the aggregate carrying amount to exceed the aggregate recoverable amount of the related CGU. The estimated recoverable amount of the British Columbia CGU including goodwill exceeded its carrying amount as at December 31, 2023, accordingly no impairment was recorded.

As such, management determined that a detailed impairment evaluation as at March 31, 2023 was required for the Peru CGU. For the impairment test completed at March 31, 2023, FVLCD was used to determine the recoverable amount since it is higher than value in use. FVLCD was calculated using discounted after-tax cash flows based on cash flow projections and assumptions in Hudbay's most current LOM. The fair value measurement in its entirety is categorized as Level 3 based on the degree to which fair value inputs are observable and have a significant effect on the recorded fair value. LOM plans are based on optimized mine and processing plans and the assessment of capital expenditure requirements of a mine site. LOM plans incorporate management's best estimates of key assumptions which are discount rates, future commodity prices, production based on current estimates of recoverable reserves, future operating and capital costs, value of mineral resources not included in the LOM plan and future foreign exchange rates. The cash flows are for periods up to the date that production is expected to cease, which is 16 years for the Peru CGU. The discount rate was based on the CGU's weighted average cost of capital, of which the two main components are the cost of equity and the after-tax cost of debt. Cost of equity was calculated based on the capital asset pricing model, incorporating the risk-free rate of return based on the US Government's marketable bond yields as at the valuation date, the Company's beta coefficient adjustment to the market equity risk premium based on the volatility of the Company's return in relation to that of a comparable market portfolio, plus a country risk premium, size premium and company-specific risk factor. Cost of debt was determined by applying an appropriate market indication of the Company's borrowing capabilities and the corporate income tax rate applicable to the segment's jurisdiction. A real discount rate of 7.00% for the Peru CGU was used to calculate the estimated after- tax discounted future net cash flows, commensurate with its individual estimated level of risk. Commodity prices used in the impairment assessment were determined by reference to external market participant sources. The key commodity price for this assessment is the price of copper. Where applicable to each of the Group's CGUs, the cash flow calculations were based on estimates of future production levels applying forecasts for metal prices, which included forecasts for each year from 2023 to 2027 and long-term forecasts for years beginning in 2028. The cash flow calculations utilized a copper price of $3.75/lb starting in 2023. The cash flow calculations utilized a long-term copper price of $3.75/lb, and capital, operating and reclamation costs based on the most current LOM plans. A value of $210,000 was utilized to estimate the value of mineral resources not included in the LOM plan. Expected future cash flows used to determine the FVLCD used in the impairment testing are inherently uncertain and could materially change over time. Should management's estimate of the future not reflect actual events, impairments may be identified. This may have a material effect on the Company's financial statements. Although it is reasonably possible for a change in key assumptions to occur, the possible effects of a change in any single assumption may not fairly reflect the impact on a CGU's fair value as the assumptions are inextricably linked. For example, a decrease in the assumed price of long-term copper could result in amendments to the mine plans which would partially offset the effect of lower prices. It is difficult to determine how all of these factors would interrelate; however, in deriving a recoverable amount, management believes all of these factors need to be considered. As of March 31, 2023, a reasonably possible change in one of the key assumptions, all else being equal, may cause the carrying value to exceed the recoverable amount. Management determined that the fair value less cost to dispose exceeded the carrying value of the Peru CGU, accordingly no impairment was recorded. At December 31, 2022, capital works in progress decreased compared to December 31, 2021 as a result of a pre-tax impairment charge of $94,956 related to certain capitalized costs and assets associated with the previous stand-alone development plan for the East deposit that are no longer recoverable (see note 7g). The closure of the Flin Flon operations in the second quarter of 2022 has led to the derecognition of fully depreciated assets. This resulted in a decrease in both the cost and accumulated depreciation of the Mining Properties and Plant and Equipment categories. An indicator of impairment was identified in the second quarter of 2022 as a result of the recently released PEA and new mine plan for the Copper World Complex in Arizona. As such, management determined that a detailed impairment evaluation as at June 30, 2022 was required for the Arizona CGU. Management determined that the fair value less cost to dispose exceeded the carrying value of the Arizona CGU, accordingly no impairment was recorded.

The interest rates on leases which were capitalized have interest rates between 2.39% and 8.49%, per annum. The range of interest rates utilized for discounting varies depending mostly on the Hudbay entity acting as lessee and duration of the lease. For certain leases, Hudbay has the option to purchase the equipment and vehicles leased at the end of the terms of the leases. Hudbay's obligations under these leases are secured by the lessor's title to the leased assets. The present value of applicable lease payments has been recognized as an ROU asset, which was included as a non-cash addition to property, plant and equipment, and a corresponding amount as a lease liability. There are no restrictions placed on Hudbay by entering into these leases. The following outlines expenses recognized within the Company's consolidated income statements, relating to leases for which a recognition exemption was applied.

Disclosure Of Deferred Revenue [Abstract]
Deferred revenue [Text Block]	21. Deferred revenue Peru Stream Agreement For the year ended December 31, 2023, the drawdown rates for the Peru stream agreement for gold and silver were $820 and $15.26 per ounce, respectively (year ended December 31, 2022 - $734 and $14.95 per ounce, respectively). 777 Stream Agreement As of September 30, 2022 all of 777's precious metals reserves and inventory levels have been depleted and we expect no further drawdown of deferred revenue. As part of the streaming agreement for the 777 mine, Hudbay must repay, with precious metals credits, the stream deposit by August 1, 2052, the expiry date of the agreement. If the stream deposit is not fully repaid with precious metals credits from 777 production by the expiry date, a payment for the remaining amount will be due at the expiry date of the agreement. As the 777 mine has concluded all mining activities following the depletion of reserves and finalized the sales of produced concentrate, Hudbay concluded that the remaining stream deposit will not be repaid by means of precious metals credits from 777 production. The repayment amount is recorded as a Wheaton refund liability (note 17), The following table summarizes changes in deferred revenue: Balance, January 1, 2022 $ 515,326 Amortization of deferred revenue (note 7a) Liability drawdown (72,229 ) Variable consideration adjustments - prior periods (959 ) Accretion on streaming arrangements (note 7f) Current year additions 28,718 Variable consideration adjustments - prior periods (940 ) Effects of changes in foreign exchange (378 ) Balance, December 31, 2022 $ 469,538 Amortization of deferred revenue (note 7a) Liability drawdown (72,424 ) Variable consideration adjustments - prior periods (4,885 ) Accretion on streaming arrangements (note 7f) Current year-to-date additions 26,387 Variable consideration adjustments - prior periods (96 ) Balance, December 31, 2023 $ 418,520 Consideration from the Company's stream agreement is considered variable. Gold and silver stream revenue can be subject to cumulative adjustments when the number of ounces to be delivered under the contract changes. As a result of changes in the Company's mineral reserve and resource estimate in the first quarter of 2023, the amortization rate by which deferred revenue is drawn down into income was adjusted and, as required, a current period variable adjustment was made for all prior period stream revenues since the stream agreement inception date. This variable consideration adjustment resulted in an increase in revenue of $4,885 and a decrease of finance expense of $96 for the year ended December 31, 2023 (December 31, 2022 - increase in revenue of $959 and a decrease of finance expense of $940). Deferred revenue is reflected in the consolidated balance sheets as follows: Dec. 31, 2023 Dec. 31, 2022 Current $ 87,672 $ 64,658 Non-current 330,848 404,880 $ 418,520 $ 469,538

Decommissioning, restoration and similar liabilities ("DRO") Hudbay's decommissioning, restoration and similar liabilities relate to the rehabilitation and closure of currently operating mines and metallurgical plants, development-phase properties and closed properties. The amount of the provision has been recorded based on estimates and assumptions that management believes are reasonable; however, actual decommissioning and restoration costs may differ from expectations. DRO are remeasured at each reporting date to reflect changes in discount rates, inflation, exchange rates, and timing and extent of cash outflows which can significantly affect the liabilities. The amount of this provision has been recorded based on estimates and assumptions that management believes are reasonable; however, actual decommissioning and restoration costs may differ from expectations. During the year ended December 31, 2023, the Company recorded a non-cash gain of $11,416 i Hudbay's decommissioning and restoration liabilities relate mainly to its Manitoba, Peru and British Columbia operations. Management has placed the remaining Flin Flon assets on care and maintenance. The majority of closure activities will occur once all mining activities in Manitoba are completed. These provisions also reflect estimated post-closure cash flows that extend to the year 2123 for ongoing monitoring and water treatment requirements. Management anticipates most decommissioning and restoration activities for the Peru operation will occur from 2035 to 2103, which include ongoing monitoring and water treatment requirements. Management anticipates most decommissioning and restoration activities for the British Columbia operation will occur from 2041 to 2142, which include ongoing monitoring and water treatment requirements. As at December 31, 2023, decommissioning, restoration and similar liabilities have been discounted to their present value at rates ranging from 3.01% to 4.86% per annum (December 31, 2022 - 3.26% to 4.75%), using pre-tax, risk-free interest rates that reflect the estimated maturity of each specific liability.

Pension Obligations [Abstract]
Pension obligations [Text Block]	23. Pension obligations Hudbay maintains non-contributory and contributory defined benefit pension plans for certain of its employees. The Company uses a December 31 measurement date for all of its plans. For Hudbay's significant plans, the most recent actuarial valuations filed for funding purposes were performed during 2023 using the latest data available as at December 31, 2022. For these plans, the next actuarial valuation required for funding purposes will be performed during 2024 using the data as of December 31, 2023. During 2023, an annuity purchase transaction was entered into in which the defined benefit obligations associated with certain defined benefit plan members were assumed by a third-party insurer in exchange for a lump sum payment of $34,857 from plan assets. Movements in the present value of the defined benefit obligation in the current and previous years were as follows: Year ended Dec. 31, 2023 Dec. 31, 2022 Opening defined benefit obligation: $ 145,129 $ 216,369 Current service costs 5,172 9,392 Past service cost/(curtailment) (note 7d) 50 (583 ) Loss on settlements 149 - Interest cost 6,274 5,938 Benefits paid from plan (13,721 ) (18,637 ) Benefits paid from employer (1,091 ) (1,787 ) Participant contributions 16 25 Effects of movements in exchange rates 3,043 (16,883 ) Remeasurement actuarial losses/(gains): Arising from changes in demographic assumptions - - Arising from changes in financial assumptions 7,045 (48,960 ) Arising from experience adjustments (1,876 ) 255 Settlement payments from plan assets (34,857 ) - Closing defined benefit obligation $ 115,333 $ 145,129 The defined benefit obligation closing balance, by member group, is as follows: Dec. 31, 2023 Dec. 31, 2022 Active members $ 103,523 $ 112,951 Deferred members 2,318 2,439 Retired members 9,492 29,739 Closing defined benefit obligation $ 115,333 $ 145,129 Movements in the fair value of the pension plan assets in the current and previous years were as follows: Year ended Dec. 31, 2023 Dec. 31, 2022 Opening fair value of plan assets: $ 137,721 $ 199,645 Interest income 5,973 5,667 Remeasurement adjustment: Return (loss) on plan assets (excluding amounts included in net interest expense) 6,228 (40,196 ) Contributions from the employer 2,265 6,063 Employer direct benefit payments 1,091 1,787 Contributions from plan participants 16 25 Benefit payment from employer (1,091 ) (1,787 ) Administrative expenses paid from plan assets (81 ) (80 ) Benefits paid (13,721 ) (18,637 ) Settlement payments from plan assets (34,857 ) - Effects of changes in foreign exchange rates 2,495 (14,766 ) Closing fair value of plan assets $ 106,039 $ 137,721 The amount included in the consolidated balance sheets arising from the entity's obligation in respect of its defined benefit plans is as follows: Dec. 31, 2023 Dec. 31, 2022 Present value of funded defined benefit obligation $ 100,024 $ 131,503 Fair value of plan assets (106,039 ) (137,721 ) Present value of unfunded defined benefit obligation 15,309 13,626 Net liability arising from defined benefit obligation $ 9,294 $ 7,408 Reflected in the consolidated balance sheets as follows: Dec. 31, 2023 Dec. 31, 2022 Pension obligation - current (note 16) $ 3,284 $ 4,146 Pension obligation - non-current 6,010 3,262 Total pension obligation $ 9,294 $ 7,408 Pension expense is as follows: Dec. 31, 2023 Dec. 31, 2022 Service costs: Current service cost $ 5,172 $ 9,392 Curtailment - (583 ) Loss on settlement 149 - Total service cost 5,321 8,809 Net interest expense 301 271 Administration cost 81 80 Defined benefit pension expense $ 5,703 $ 9,160 Defined contribution pension expense $ 701 $ 2,097 Remeasurement on the net defined benefit liability: Dec. 31, 2023 Dec. 31, 2022 (Return) loss on plan assets (excluding amounts included in net interest expense) $ (6,228 ) $ 40,196 Actuarial losses (gains) arising from changes in financial assumptions 7,045 (48,960 ) Actuarial (gains) losses arising from experience adjustments (1,876 ) 255 Defined benefit gain related to remeasurement $ (1,059 ) $ (8,509 ) Total pension cost $ 5,345 $ 2,748 Pension amounts recognized include those directly related to production of inventory; such amounts are recognized initially as costs of inventory and are expensed in the consolidated income statements within cost of sales upon sale of the inventory. The current service cost, the interest cost and administration cost for the year are included in the employee benefits expense. The remeasurement of the net defined benefit liability is included in OCI. The defined benefit pension plans typically expose Hudbay to actuarial risks such as: investment risk, interest rate risk, longevity risk and salary risk. Investment risk The present value of the liabilities for the defined benefit plans is calculated using a discount rate determined by reference to high quality corporate bond yields; if the return on plan assets is below this rate, it will create a plan deficit. Hudbay's primary quantitative investment objectives are maximization of the long term real rate of return, subject to an acceptable degree of investment risk and preservation of principal. Risk tolerance is established through consideration of several factors including past performance, current market condition and the funded status of the plan. Interest risk A decrease in the bond interest rate will increase the pension plan liabilities; however, this will be partially offset by an increase in the return on the plan's debt investments. Longevity risk The present value of the defined benefit plans liabilities is calculated by reference to the best estimate of the mortality of plan participants both during and after their employment. An increase in the life expectancy of the plan participants will increase the pension plans liabilities. Salary risk The present value of the defined benefit plans liabilities for some of the pension plans is calculated by reference to the future salaries of plan participants. As such, an increase in the salary of the plan participants will increase the plans' liabilities. The principal assumptions used for the purposes of the actuarial valuations were as follows: 2023 2022 Defined benefit cost: Discount rate - benefit obligations 5.22% 3.09% Discount rate - service cost 5.27% 3.21% Expected rate of salary increase 1 3.50% 2.75% Average longevity at retirement age for current pensioners (years) 2 Males 20.4 20.4 Females 23.8 23.7 Defined benefit obligation: Discount rate 4.64% 5.22% Expected rate of salary increase 1 3.00 % 3.50% Average longevity at retirement age for current pensioners (years) 2 Males 20.5 20.4 Females 23.9 23.8 Average longevity at retirement age for current employees (future pensioners) (years) 2 Males 22.4 22.3 Females 25.6 25.5 1 2 Hudbay reviews the assumptions used to measure pension costs (including the discount rate) on an annual basis. Economic and market conditions at the measurement date affect these assumptions from year to year. In determining the discount rate, Hudbay considers the duration of the pension plan liabilities. Significant actuarial assumptions for the determination of the defined benefit obligation are discount rate, expected salary increase and mortality. The sensitivity analysis below has been determined based on reasonably possible changes of the respective assumptions occurring at the end of the reporting periods, while holding other assumptions constant: - If the discount rate is 50 basis points higher (lower), the defined benefit obligation would decrease by $9,363 (increase by $10,650). - If the expected salary growth increases (decreases) by 1%, the defined benefit obligation would increase by $1,536 (decrease $1,264). - If the life expectancy increases (decreases) by one year for both men and women, the defined benefit obligation would increase by $726 (decrease by $769). The sensitivity analysis presented above may not be representative of the actual change in the defined benefit obligation as it is unlikely that the change in assumptions would occur in isolation of one another as some of the assumptions may be correlated. Furthermore, in presenting the above sensitivity analysis, the present value of the defined benefit obligation has been calculated using the projected unit credit method at the end of the reporting period, which is the same as that applied in calculating the defined benefit obligation liability recognized in the consolidated balance sheets. The Company's main pension plans are registered federally with the Office of the Superintendent of Financial Institution and with the Canada Revenue Agency. The registered pension plans are governed in accordance with the Pension Benefits Standards Act and the Income Tax Act. The sponsor contributes the amount needed to maintain adequate funding as dictated by the prevailing regulations. Expected employer contribution to the pension plans for the fiscal year ending December 31, 2023 is $3,284. The average duration of the pension obligation at December 31, 2023 is 18.0 years (2022 - 16.2 years). This number can be broken down as follows: - Active members: 18.8 years (2022: 18.3 years) - Deferred members: 19.2 years (2022: 17.5 years) - Retired members: 9.0 years (2022: 8.2 years) Asset-Liability-Matching studies are performed periodically to analyze the investment policies in terms of risk and-return profiles. The pension plans do not invest directly in either securities or property/real estate of the Company. With the exception of fixed income investments and certain equity instruments, the plan assets are actively managed by investment managers, with the goal of attaining returns that potentially outperform passively managed investments. Within appropriate limits, the actual composition of the invested funds may vary from the prescribed investment mix. The following is a summary of the fair value classification levels for investment: December 31, 2023 Level 1 Level 2 Level 3 Total Investments: Money market instruments $ 1,166 $ - $ - $ 1,166 Pooled equity funds 33,930 - - 33,930 Pooled fixed income funds - 69,968 - 69,968 Alternative investment funds - 908 - 908 Balanced funds - 67 - 67 $ 35,096 $ 70,943 $ - $ 106,039 December 31, 2022 Level 1 Level 2 Level 3 Total Investments: Money market instruments $ 2,270 $ - $ - $ 2,270 Pooled equity funds 50,107 - - 50,107 Pooled fixed income funds - 64,230 - 64,230 Alternative investment funds - 20,908 - 20,908 Balanced funds - 206 - 206 $ 52,377 $ 85,344 $ - $ 137,721

Other Employee Benefits [Abstract]
Other employee benefits [Text Block]	24. Other employee benefits Hudbay sponsors both other long-term employee benefit plans and non-pension post-employment benefits plans and uses a December 31 measurement date. These obligations relate mainly to commitments for post-retirement health benefits. Information about Hudbay's post-employment and other long-term employee benefits is as follows: Movements in the present value of the defined benefit obligation in the current and previous years were: Year ended Dec. 31, 2023 Dec. 31, 2022 Opening defined benefit obligation $ 87,216 $ 128,843 Current service cost 1 2,815 4,656 Curtailment (note 7d) - (1,801 ) Interest cost 4,456 3,940 Attribution period changes (note 7d) - (3,179 ) Effects of movements in exchange rates 2,299 (6,074 ) Remeasurement actuarial losses/(gains): Arising from changes in demographic assumptions 502 - Arising from changes in financial assumptions 9,250 (36,058 ) Arising from experience adjustments (637 ) (516 ) Benefits paid (2,741 ) (2,595 ) Closing defined benefit obligation $ 103,160 $ 87,216 1 The defined benefit obligation closing balance, by group member, is as follows: Dec. 31, 2023 Dec. 31, 2022 Active members $ 36,871 $ 28,734 Inactive members 66,289 58,482 Closing defined benefit obligation $ 103,160 $ 87,216 Movements in the fair value of defined benefit amounts in the current and previous years were as follows: Dec. 31, 2023 Dec. 31, 2022 Employer contributions $ 2,741 $ 2,595 Benefits paid (2,741 ) (2,595 ) Closing fair value of assets $ - $ - The non-pension employee benefit plan obligations are unfunded.

The other employee benefit costs typically expose Hudbay to actuarial risks such as: interest rate risk, health care cost inflation risk and longevity risk. Interest risk A decrease in the bond interest rate will increase the plan liabilities. Health care cost inflation risk The majority of the plan's benefit obligations are linked to health care cost inflation and higher inflation will lead to higher liabilities. Longevity risk The majority of the plans' benefit liability is calculated by reference to the best estimate of the mortality of plan participants both during and after their employment. An increase in the life expectancy of the plan participants will increase the plans' liabilities. This is particularly significant for benefits subject to health care cost inflation where increases in inflation result in higher sensitivity to changes in life expectancy. The sensitivity analyses below have been determined based on reasonably possible changes of the respective assumptions occurring at the end of the reporting period, while holding other assumptions constant: - - - The average duration of the non-pension post-employment obligation at December 31, 2023 is 15.8 This number can be broken down as follows: - - .6

Major components of tax expense (income) [abstract]
Income and mining taxes [Text Block]	25. Income and mining taxes (a) Tax recoveries: The tax expense (recoveries) is applicable as follows: Year ended December 31, 2023 2022 Current: Income taxes $ 87,490 $ 10,940 Mining taxes 21,974 10,673 Adjustments in respect of prior years (4,383 ) (704 ) 105,081 20,909 Deferred: Income tax (recoveries) expense - origination, revaluation and/or reversal of temporary differences (25,854 ) 218 Mining tax (recoveries) expense - origination, revaluation and/or reversal of temporary difference (2,431 ) 5,464 Adjustments in respect of prior years 5,491 (1,158 ) (22,794 ) 4,524 $ 82,287 $ 25,433 Adjustments in respect of prior years refers to amounts changing due to the filing of tax returns and assessments from government authorities as well as any change identified that would result in a difference to our current or deferred tax balances as reported in the prior fiscal year end. (b) Deferred tax assets and liabilities as represented on the consolidated balance sheets: Dec. 31, 2023 Dec. 31, 2022 Deferred income tax asset $ 151,946 $ 125,638 Deferred income tax liability (362,767 ) (233,730 ) Deferred mining tax liability (44,385 ) (17,564 ) (407,152 ) (251,294 ) Net deferred tax liability balance, end of year $ (255,206 ) $ (125,656 ) (c) Changes in deferred tax assets and liabilities: Year ended December 31, 2023 2022 Net deferred tax liability balance, beginning of year $ (125,656 ) $ (128,180 ) Deferred tax recovery (expense) (note 25a) 22,794 (4,524 ) OCI transactions (225 ) (2,384 ) Foreign currency translation on the deferred tax liability (3,873 ) 9,432 Acquisition of Copper Mountain mining (note 5) (148,246 ) - Net deferred tax liability balance, end of year $ (255,206 ) $ (125,656 ) (d) Reconciliation to statutory tax rate: As a result of its mining operations, the Company is subject to both income and mining taxes. Generally, most expenditures incurred are deductible in computing income tax, whereas mining tax legislation, although based on a measure of profitability from carrying on mining operations, is more restrictive in respect of the deductions permitted in computing income subject to mining tax. These restrictions include costs unrelated to mining operations as well as deductions for financing expenses, such as interest and royalties. In addition, income unrelated to carrying on mining operations is not subject to mining tax. A reconciliation between tax expense and the product of accounting profit multiplied by the Company's statutory income tax rate for the years ended December 31, 2023 and 2022 is as follows: Year ended December 31, 2023 2022 Profit before tax $ 151,830 $ 95,815 Statutory tax rate 26.2% 26.3% Tax expense at statutory rate 39,779 25,199 Effect of: Deductions related to mining taxes (6,937 ) (3,249 ) Adjusted income taxes 32,842 21,950 Mining tax expense 18,827 15,959 51,669 37,909 Permanent differences related to: Capital items 371 (321 ) Other income tax permanent differences 870 3,839 Withholding tax on dividends 11,750 - Impact of remeasurement on decommissioning liability (6,363 ) (38,950 ) Temporary income tax differences not recognized 5,448 (509 ) Recognition of previously unrecognized deferred tax assets (5,335 ) (3,943 ) Impact related to differences in tax rates in foreign operations 27,931 15,339 Impact of changes to statutory tax rates 878 958 Foreign exchange on non-monetary items (7,384 ) 13,094 Impact related to tax assessments and tax return amendments 1,906 (1,983 ) Other 546 - Tax expense $ 82,287 $ 25,433 (e) Income tax effect of temporary differences - recognized: The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities at December 31, 2023 and 2022 are as follows: Balance sheet Dec. 31, 2023 Dec. 31, 2022 Deferred income tax (liability) asset Property, plant and equipment $ (50,367 ) $ (44,029 ) Pension obligation 2,531 2,121 Other employee benefits 26,928 25,395 Decommissioning and restoration provision 20,031 20,454 Non-capital losses 135,284 104,481 Share issuance and debt cost 6,646 6,283 Deferred revenue 1,532 1,195 Other 9,361 9,738 Deferred income tax asset 151,946 125,638 Deferred income tax liability (asset) Property, plant and equipment 478,657 311,499 Other employee benefits (1,193 ) (1,024 ) Decommissioning and restoration provision (19,231 ) (8,376 ) Non-capital losses (91,951 ) (71,532 ) Other (3,515 ) 3,163 Deferred income tax liability 362,767 233,730 Deferred income tax liability $ (210,821 ) $ (108,092 ) The above reconciling items are disclosed at the tax rates that apply in the jurisdiction where they have arisen. (f) Income tax temporary differences - not recognized: The Company has not recognized a deferred tax asset on $43,134 of non-capital losses (December 31, 2022 - $44,451), $183,228 of capital losses (December 31, 2022 - $154,560) and $482,944 (December 31, 2022 - $255,938) of other deductible temporary differences since the realization of any related tax benefit through future taxable profits is not probable. The capital losses have no expiry dates and the other deductible temporary differences do not expire under current tax legislation. The Canadian non-capital losses were incurred between 2013 and 2023 and have a twenty-year carry forward period. The United States net operating losses incurred between 2004 and 2017 have a twenty-year carry forward period. United States net operating losses incurred between 2018 and 2023 may be carried forward indefinitely but are restricted to being applied against a maximum of 80% of taxable income. (g) Mining tax effect of temporary differences: The tax effects of temporary differences that give rise to significant portions of the deferred mining tax assets and liabilities at December 31, 2023 and 2022 are as follows: Canada Dec. 31, 2023 Dec. 31, 2022 Property, plant and equipment $ (52,633 ) $ (4,996 ) Other 17,621 - $ (35,012 ) $ (4,996 ) Peru Dec. 31, 2023 Dec. 31, 2022 Property, plant and equipment $ (9,373 ) $ (12,568 ) For the year ended December 31, 2023, Hudbay had unrecognized deferred mining tax assets of approximately $9,695 (December 31, 2022 - $10,198). (h) Unrecognized taxable temporary differences associated with investments: There are no taxable temporary differences associated with investments in subsidiaries, associates and joint ventures, for which a deferred tax liability has not been recognized. (i) Taxes receivable/payable: The timing of payments results in significant variances in period-to-period comparisons of the tax receivable and tax payable balances. (j) Other disclosure: The tax rules and regulations applicable to mining companies are highly complex and subject to interpretation. The Company may be subject in the future to a review of its historic income and other tax filings and, in connection with such reviews, disputes can arise with tax authorities over the interpretation or application of certain tax rules and regulations in respect of the Company's business. These reviews may alter the timing or amount of taxable income or deductions. The amount ultimately reassessed upon resolution of issues raised may differ from the amount accrued.

Share-based compensation [Text Block]	27. Share-based compensation (a) Cash-settled share-based compensation: Hudbay has three cash-settled share-based compensation plans, as described below. Deferred Share Units (DSU) At December 31, 2023, the carrying amount and the intrinsic value of the outstanding liability related to the DSU plan was $8,660 (December 31, 2022 - $6,872) (note 22). The following table outlines information related to DSUs granted, expenses recognized and payments made during the year. Year ended Dec. 31, 2023 Dec. 31, 2022 Granted during the year: Number of units 210,472 238,627 Weighted average price (C$/unit) $ 7.02 $ 6.45 Expenses (gain) recognized during the year 1 $ 1,717 $ (849 ) 1 Restricted Share Units (RSU) RSUs granted under the LTEP Plan may be settled in the form of Hudbay common shares or, at the option of the Company, the cash equivalent based on the market price of the common shares as of the vesting date. RSUs may also be granted under Hudbay's Share Unit Plan, however; the RSUs granted under the Share Unit Plan may only be settled in cash. Hudbay has historically settled all RSUs in cash. The Company has determined that the appropriate accounting treatment is to classify the RSUs as cash settled transactions. At December 31, 2023, the carrying amount of the outstanding liability related to the RSU plan was $5,088 (December 31, 2022 - $6,855) (note 22). The following table outlines information related to RSUs granted, expenses recognized and payments made in the year.

Hudbay has historically settled similar share-based compensation units in cash. The Company has determined that the appropriate accounting treatment is to classify the PSUs as cash settled transactions. The PSUs contain a performance based multiplier element which will be computed upon vesting. At December 31, 2023, the carrying amount of the outstanding liability related to PSU plan was $2,580 (December 31, 2022 - $2,989) (note 22). The following table outlines information related to PSUs granted, expenses recognized and payments made in the year.

Under the amended Plan, the Company may grant to employees, officers, directors or consultants of the Company or its affiliates options to purchase up to a maximum of 13 million common shares of Hudbay. The Company has determined that the appropriate accounting treatment is to classify the stock options as equity settled transactions. During the year ended December 31, 2023, the Company granted 801,661 stock options (year ended December 31, 2022 - 602,614).

Hudbay's long-term debt balance as at December 31, 2023 was $1,287,536 (December 31, 2022 - $1,184,162). The Company's objectives when managing capital are to maintain a strong capital base in order to: - - Hudbay monitors its capital and capital structure on an ongoing basis to ensure they are sufficient to achieve the Company's short-term and long-term strategic objectives in a capital intensive industry. Hudbay faces several risks, including volatile metals prices, inflationary pressures on costs, access to capital, and risk of delays and cost escalation associated with major capital projects. The Company continually assesses the adequacy of its capital structure to ensure its objectives are met. Hudbay monitors its cash, which was $249,794 as at December 31, 2023 (2022 - $225,665), together with availability under its committed credit facilities. Hudbay invests its cash primarily in Canadian bankers' acceptances, deposits at major Canadian and Peruvian banks, or treasury bills issued by the federal or provincial governments. In addition to the requirement to maintain sufficient cash balances to fund continuing operations, Hudbay must maintain sufficient cash to fund the interest expense on the long-term debt outstanding (note 20). As part of the Company's capital management activities, Hudbay monitors interest coverage ratios and leverage ratios.

During the year ended December 31, 2023 and year ended December 31, 2022, Hudbay did not make any such transfers. Changes to inputs of financial instruments categorized as Level 3 were insignificant. (b) Derivatives and hedging: Copper fixed for floating swaps Hudbay enters into copper fixed for floating swaps in order to manage the risk associated with provisional pricing terms in copper concentrate sales agreements. As at December 31, 2023, Hudbay had 90.6 million pounds of net copper swaps outstanding at an effective average price of $3.74/lb and settling from January to May 2024. As at December 31, 2022, Hudbay had 89.7 million pounds of net copper swaps outstanding at an effective average price of $3.61/lb and settling from January to May 2023. The aggregate fair value of the transactions at December 31, 2023 was a liability of $9,515 (December 31, 2022 - a liability position of $17,269). Zinc fixed for floating swaps Hudbay enters into zinc fixed for floating swaps in order to manage the risk associated wi th provisional pricing terms in zinc concentrate sales agreements. As at December 31, 2023, Hudbay had 13.9 million f $945 Copper forward sale During the second half of 2023, Hudbay entered into forward sales contracts for a total of 5,600 tonnes of copper production. As of December 31, 2023, Hudbay had 7.9 million pounds of copper forwards outstanding at an effective average price of $3.93/lb and settling from May 2024 to April 2025. The aggregate fair value of the transactions at December 31, 2023 was an asset of $65. Hudbay held no forward copper purchase contracts as at December 31, 2022. Copper costless collars During the fourth quarter of 2023, Hudbay entered into zero-cost collar program for 6,000 tonnes of copper production over the twelve-month period from May 2024 to April 2025 at an average floor price of $3.83/lb and an average cap price of $4.03/lb. Gains and losses resulting from the settlement of these derivatives are recorded directly to revenue, as the forward sales contracts do not qualify for hedge accounting, and the associated cash flows are classified in operating activities. As at December 31, 2023, 13.2 million pounds of copper collars were unsettled (December 31, 2022 - nil). The aggregate fair value of the position at December 31, 2023 was nil (December 31, 2022 - nil). (c) Provisionally priced receivables Changes in fair value of provisionally priced receivables Hudbay records changes in fair value of provisionally priced receivables related to provisional pricing in concentrate purchase, concentrate sale and certain other sale contracts. Under the terms of these contracts, prices are subject to final adjustment at the end of a future period after title transfers based on quoted market prices during the quotation period specified in the contract. The period between provisional pricing and final pricing is typically up to three months. Changes in fair value of provisionally priced receivables are presented in trade and other receivables when they relate to sales contracts and in trade and other payables when they relate to purchase contracts. At each reporting date, provisionally priced metals are marked-to-market based on the forward market price for the quotation period stipulated in the contract, with changes in fair value recognized in revenue for sales contracts and in inventory or cost of sales for purchase concentrate contracts. Cash flows related to changes in fair value of provisionally priced receivables are classified in operating activities. As at December 31, 2023 and December 31, 2022, Hudbay's net position consisted of contracts awaiting final pricing are as indicated below: Metal in concentrate Sales awaiting final pricing Average YTD price ($/unit) Unit Dec. 31, 2023 Dec. 31, 2022 Dec. 31, 2023 Dec. 31, 2022 Copper pounds (in thousands) 111,069 79,833 3.87 3.80 Gold troy ounces 50,563 22,079 2,072 1,823 Silver troy ounces 205,579 71,809 23.94 23.91 Zinc pounds (in thousands) 16,416 18,145 1.20 1.35 The aggregate fair value of provisionally priced receivables within the copper and zinc concentrate at December 31, 2023, was an asset positi on of $22,635 (d) Other financial liabilities Gold prepayme nt liability The gold prepayment lia bility (note 18) requires settlement by physical delivery of gold ounces or equivalent gold credit (e) Financial risk management Hudbay's financial risk management activities are governed by Board-approved policies addressing risk identification, hedging authorization procedures and limits and reporting. The Company's policy objective, when hedging activities are undertaken, is to reduce the volatility of future profit and cash flow within the strategic and economic goals of Hudbay. From time to time, the Company employs derivative financial instruments, including forward and option contracts, to manage risk originating from exposures to commodity price risk, foreign exchange risk and interest rate risk. Significant derivative transactions are approved by the Board of Directors, and hedge accounting is applied when certain criteria have been met. Hudbay does not use derivative financial instruments for trading or speculation purposes. The following is a discussion of the Company's risk exposures. (i) Market risk Market risk is the risk that changes in market prices, including foreign exchange rates, commodity prices, share prices, and interest rates will cause fluctuations in the fair value or future cash flows of a financial instrument. Foreign currency risk Hudbay's primary exposure to foreign currency risk arises from: - - The Manitoba and British Columbia segment's primary financial instrument foreign currency exposure is on US denominated cash, trade and other receivables and other financial liabilities. The Peru segment's primary financial instrument foreign currency exposure is on Peruvian soles cash, trade and other payables and other financial liabilities. The Company's exposure to foreign currency risk was as follows based on notional financial instrument amounts stated in US equivalent dollars: Dec. 31, 2023 Dec. 31, 2022 CAD 1 USD 2 PEN 3 CAD 1 USD 2 PEN 3 Cash $ 19,039 $ 16,737 $ 1,956 $ 9,833 $ 26,749 $ 11,067 Trade and other receivables 34 76,251 333 58 20,520 634 Other financial assets 6,452 - - 9,799 - - Trade and other payables (6,090 ) - (20,988 ) (5,626 ) (113 ) (29,587 ) Other financial liabilities - - (54,979 ) - - (42,493 ) $ 19,435 $ 92,988 $ (73,678 ) $ 14,064 $ 47,156 $ (60,379 ) 1 2 3 The following sensitivity analysis for foreign currency risk relates solely to financial instruments and non-financial derivatives that were outstanding as at the year-end date; each sensitivity calculation assumes all other variables are held constant. This analysis is based on values as at December 31, 2023 and does not reflect the overall effect that changes in market variables would have on the Company's operating results. December 31, 2023 Change of: Would have changed 2023 after-tax profit by: USD/CAD exchange rate 1 + 10% $ 3.7 million USD/CAD exchange rate 1 - 10% (4.5 ) million USD/PEN exchange rate 2 + 10% 4.4 million USD/PEN exchange rate 2 - 10% (5.3 ) million December 31, 2022 Change of: Would have changed 2022 after-tax profit by: USD/CAD exchange rate 1 + 10% $ 1.5 million USD/CAD exchange rate 1 - 10% (1.8 ) million USD/PEN exchange rate 2 + 10% 3.5 million USD/PEN exchange rate 2 - 10% (4.3 ) million 1 2 Commodity price risk Hudbay is exposed to market risk from prices for the commodities the Company produces and sells, such as copper, zinc, gold and silver. From time to time, Hudbay maintains price protection programs and conducts commodity price risk management through the use of derivative contracts. The following sensitivity analysis for commodity price risk relates solely to financial instruments and non-financial derivatives that were outstanding as at the year-end date; each sensitivity calculation assumes all other variables are held constant. This analysis is based on values as at December 31, 2023 and does not reflect the overall effect that changes in market variables would have on the Company's operating results. December 31, 2023 Change of: Would have changed 2023 after-tax profit by: Copper prices ($/lb) 1 + $0.30 $ 2.6 million Copper prices ($/lb) 1 - $0.30 (2.0 ) million Zinc prices ($/lb) 2 + $0.10 0.1 million Zinc prices ($/lb) 2 - $0.10 (0.1 ) million December 31, 2022 Change of: Would have changed 2022 a fter-tax profit by: Copper prices ($/lb) 1 + $0.30 $ (1.8 ) million Copper prices ($/lb) 1 - $0.30 1.8 million Zinc prices ($/lb) 2 + $0.10 - million Zinc prices ($/lb) 2 - $0.10 - million 1 2 Share price risk Hudbay is exposed to market risk from share prices of the Company's investments in listed Canadian metals and mining entities. These investments are made to foster strategic relationships, in connection with joint venture agreements and for investment purposes. Management monitors the value of these investments for the purposes of determining whether to add or reduce Hudbay's positions. The following sensitivity analysis of share price risk relates solely to financial instruments that were outstanding as at the year-end date. This analysis is based on values as at December 31, 2023 and does not reflect the overall effect that changes in market variables would have on the Company's finance expenses. December 31, 2023 Change of: Would have changed 2023 after-tax profit by: Share prices + 25% $ 1.6 million Share prices - 25% (1.6 ) million December 31, 2022 Change of: Would have changed 2022 after-tax profit by: Share prices + 25% $ 2.4 million Share prices - 25% (2.4 ) million Interest rate risk Hudbay is exposed to the following interest rate risks: - - As at December 31, 2023, the interest rate risk relates to cash on hand and the drawn balance our revolving credit facilities. Neither the 2026 Notes nor the 2029 Notes contain embedded derivatives that require bifurcation from the host contract. This analysis only quantifies the impact of the interest rate risk on cash based on balances held and on our revolving credit facilities based on amounts drawn as at December 31, 2023 and 2022 and does not reflect the overall effect that changes in market variables would have on the Company's finance expenses. December 31, 2023 Change of: Would have changed 2023 after-tax profit by: Interest rates + 2.00% $ 3.0 million Interest rates - 2.00% (3.0 ) million December 31, 2022 Change of: Would have changed 2022 after-tax profit by: Interest rates + 2.00% $ 4.5 million Interest rates - (4.5 ) million (ii) Credit risk Credit risk is the risk of financial loss to Hudbay if a customer or counterparty to a financial instrument fails to meet its obligations. The Company's maximum exposure to credit risk at the reporting date is represented by the carrying amount, net of any impairment losses recognized, of financial assets and non-financial derivative assets recorded on the consolidated balance sheets. A large portion of Hudbay's cash are on deposits with major Schedule 1 Canadian banks. Deposits with Schedule 1 Canadian banks represented 62% of total cash as at December 31, 2023 (2022 - 64%). Hudbay's investment policy requires it to comply with a list of approved investments, concentration and maturity limits, as well as credit quality. Credit concentrations in the Company's short-term investments are monitored on an ongoing basis. Transactions involving derivatives are with counterparties Hudbay believes to be creditworthy. At December 31, 2023, approximately 76 % Two customers accounted for approximatel y 24 of (iii) Liquidity risk Liquidity risk is the risk that the Company will not be able to meet its obligations associated with financial liabilities. Hudbay's objective is to maintain sufficient liquid resources to meet operational and investing requirements. The following summarizes the contractual undiscounted cash flows of the Company's non-derivative and derivative financial liabilities, including any interest payments, by remaining contractual maturity and financial assets used to manage liquidity risk. The table includes all instruments held at the reporting date for which payments had been contractually agreed at the reporting date. The undiscounted amounts shown are gross amounts, unless the liabilities will be settled net. Amounts in foreign currency are translated at the closing rate at the reporting date. When a counterparty has a choice of when an amount is paid, the liability is allocated to the earliest possible time period.

Commitments [Text Block]	31. Commitments (a) Capital commitments As at December 31, 2023, Hudbay had outstanding capital commitments in Manitoba of approximately $ 10,066 of which $7,322 can be terminated, approximately $13,847 in British Columbia, of which approximately $11,209 can be terminated, approximately $73,398 in Peru, all of which can be terminated, and approximately $41,913 in Arizona, primarily related to the Copper World Complex, of which approximately $7,180 can be terminated. (b) Non capitalized lease commitments Hudbay has entered into various non-capitalized lease commitments for facilities and equipment. The leases expire in periods ranging from one to two years. There are no restrictions placed on the Company by entering into these leases. Future minimum lease payments under such cancellable leases recognized within results from operating activities at December 31 are: 2023 2022 Within one year $ 20,726 $ 21,016 After one year but not more than five years 9,544 25,574 More than five years 4,144 4,962 $ 34,414 $ 51,552 (c) Contingent liabilities Hudbay is involved in various claims, litigation and other matters arising in the ordinary course and conduct of business. While it is not possible to determine the ultimate outcome of such actions at this time, and inherent uncertainties exist in predicting such outcomes, it is Hudbay's belief that the ultimate resolution of such actions is not reasonably likely to have a material adverse effect on its consolidated financial position or results of operations. The assessment of contingencies inherently involves the exercise of significant judgement and estimates of the outcome of future events. As a result of the assessment, management believes that no significant contingent liabilities exist.

Disclosure of operating segments [abstract]
Segmented information [Text Block]	35. Segmented information Hudbay is an integrated metals producer. When making decisions on expansions, opening or closing mines, as well as day to day operations, management evaluates the results from operating activities of the Company. Hudbay has the following reportable segments identified by the individual mining operations of Manitoba, British Columbia, Peru, as well as Arizona which holds our Copper World project. The Manitoba, British Columbia and Peru segments generate Hudbay's revenue. The Manitoba segment sells copper concentrate (containing copper, gold and silver), silver/gold doré, zinc concentrate (containing zinc and gold) and other products. The Peru segment consists of Hudbay's Constancia operation and sells copper concentrate and molybdenum concentrate. The British Columbia segment consists of the Copper Mountain operation and sells copper concentrate. No results for the British Columbia segment are reflected in the prior year comparative figures. Hudbay's Arizona segment consists of the Copper World project located in Arizona. Corporate and other activities include the Company's exploration activities in Chile, Canada and the State of Nevada. The exploration entities are not individually significant, as they do not meet the minimum quantitative thresholds. Corporate activities are not considered a segment and are included as a reconciliation to total consolidated results. Accounting policies for each reported segment are the same as those of the Company. Results from operating activities represents the profit earned by each segment without allocation of corporate costs. This is the measure reported to the chief operating decision-maker, Hudbay's President and Chief Executive Officer, for the purposes of resource allocation and the assessment of segment performance. Total assets and liabilities do not reflect intercompany balances, which have been eliminated on consolidation.

Significant Accounting Policies [Abstract]
Basis of consolidation [Policy Text Block]	(a) Intercompany balances and transactions are eliminated upon consolidation. When a Hudbay entity transacts with an associate or jointly controlled entity of the Company, unrealized profits and losses are eliminated to the extent of Hudbay's interest in the relevant associate or joint venture. The accounting policies of Hudbay's entities are changed when necessary to align them with the policies adopted by the Company. Subsidiaries A subsidiary is an entity controlled by Hudbay. The financial statements of subsidiaries are included in the consolidated financial statements from the date that control commences until the date that control ceases. Non-controlling interest Non-controlling interest in subsidiaries are identified separately from the Company's equity in the subsidiaries. The interest of non-controlling shareholders may be initially measured either at fair value or at the non-controlling interest proportionate share of the fair value of the acquiree's identifiable net assets. The choice of measurement basis is made on an acquisition-by-acquisition basis. Subsequent to acquisition, the carrying amount of non-controlling interest is the amount of that interest at initial recognition plus the non-controlling interest share of subsequent changes in equity. Total comprehensive income is attributed to non-controlling interest even if this results in the non-controlling interest having a deficit balance. Business combinations and goodwill Should Hudbay make an acquisition, it first determines whether the assets acquired and liabilities assumed constitute a business, in which case the acquisition requires accounting as a business combination. Management applies judgement in determining whether the acquiree is capable of being conducted and managed for the purpose of providing a return, considering the inputs of the acquiree and processes applied to those inputs that have the ability to create outputs. Hudbay applies the acquisition method of accounting to business combinations, whereby the goodwill is measured at the acquisition date as the fair value of the consideration transferred including the recognized amount of any non-controlling interest in the acquiree. When the excess is negative, a bargain purchase gain is recognized immediately in the consolidated income statements. The assessment of fair values on acquisition includes those mineral reserves and resources that are able to be reliably measured. In determining these fair values, management must also apply judgement in areas including future cash flows, metal prices, exchange rates and appropriate discount rates. Changes in such estimates and assumptions could result in significant differences in the amount of goodwill recognized. The consideration transferred is the aggregate of the fair values, at the date of the acquisition, of the sum of the assets transferred, the liabilities incurred or assumed, and the equity instruments issued by the acquirer in exchange for control of the acquiree. Acquisition-related costs are recognized in the consolidated income statements as incurred, unless they relate to issuance of debt or equity securities. Where applicable, the consideration transferred includes any asset or liability resulting from a contingent consideration arrangement and measured at its acquisition date fair value. Subsequent changes in such fair values are adjusted against the cost of acquisition where they qualify as measurement period adjustments. All other subsequent changes in the fair value of contingent consideration classified as an asset or liability are accounted for in accordance with relevant IFRS. Changes in the fair value of contingent consideration classified as equity are not recognized. Where a business combination is achieved in stages, the Company's previously held interest in the acquired entity are remeasured to fair value at the acquisition date, which is the date Hudbay attains control, and any resulting gain or loss is recognized in the consolidated income statements. Amounts previously recognized in other comprehensive income ("OCI") related to interest in the acquiree prior to the acquisition date are reclassified to the consolidated income statements, where such treatment would be appropriate if that interest were disposed of. After initial recognition, goodwill is measured at cost less any accumulated impairment losses. For the purpose of impairment testing, goodwill acquired in a business combination is, from the acquisition date, allocated to each of Hudbay's CGUs that are expected to benefit from the synergies of the combination, irrespective of whether other assets or liabilities of the acquiree are assigned to those units. Goodwill is allocated to the lowest level at which it is monitored for internal management purposes and is not larger than an operating segment before aggregation. Where goodwill forms part of a CGU and part of the operation within that unit is disposed of, the goodwill associated with the disposed operation is included in the determination of any gain or loss on disposal. Goodwill is not amortized and is tested for impairment annually and whenever there is an indication of impairment. If any such indication exists, the recoverable amount of the CGU is estimated in order to determine the extent of the impairment, if any. The recoverable amount is determined as the higher of fair value less direct costs to sell and the CGU's value in use. When the recoverable amount of the CGU is less than the carrying amount of that CGU, the impairment loss is allocated to reduce the carrying amount of any goodwill allocated to that CGU first, and then to the other assets of that CGU on a pro-rata basis of the carrying amount of each asset in the CGU. An impairment loss in respect of goodwill is not reversed. Fair value for mineral interest and related goodwill is generally determined as the present value of the estimated future cash flows expected to arise from the continued use of the asset, including any expansion prospects, and its eventual disposal, using assumptions that an independent market participant may take into account. Value in use is determined as the present value of the estimated future cash flows expected to arise from the continued use of the asset in its present form and its eventual disposal. Value in use is determined by applying assumptions specific to Hudbay's continued use and cannot take into account future development. The weighted average cost of capital of Hudbay or comparable market participants is used as a starting point for determining the discount rates, with appropriate adjustments for the risk profile of the countries in which the individual CGUs operate and the specific risks related to the development of the project. Where the asset does not generate cash flows that are independent of other assets, Hudbay estimates the recoverable amount of the CGU to which the asset belongs. If the carrying amount of an asset or CGU exceeds its recoverable amount, the carrying amount of the asset or CGU is reduced to its recoverable amount. An impairment loss is recognized as an expense in the consolidated income statements.
Translation of foreign currencies [Policy Text Block]	(b) Translation of foreign currencies: Management determines the functional currency of each Hudbay entity as the currency of the primary economic environment in which the entity operates. Foreign currency transactions Transactions in foreign currencies are translated to the respective functional currencies of Hudbay's entities at exchange rates in effect at the transaction dates. At the end of each reporting period, monetary assets and liabilities denominated in foreign currencies are translated to the functional currency using the closing exchange rate. Non-monetary assets and liabilities measured at fair value are translated using the exchange rates at the date when fair value was determined. Non-monetary assets and liabilities measured at historical cost in a foreign currency are translated using exchange rates that were in effect at the transaction dates. The same translations are applied when an entity prepares its financial statements from books and records maintained in a currency other than its functional currency, except revenue and expenses may be translated at monthly average exchange rates that approximate those in effect at the transaction dates. Foreign currency gains and losses arising on period-end revaluations are recognized in the consolidated income statements, except for a financial liability designated as a hedge of a net investment in a foreign operation, or qualifying cash flow hedges, which are recognized in OCI. Foreign operations For the purpose of the consolidated financial statements, assets and liabilities of Hudbay's entities that have functional currencies other than the US dollar are translated to US dollars at the reporting date using the closing exchange rate. Revenue and expenses are translated at monthly average exchange rates that approximate those in effect at the transaction dates. Differences arising from these foreign currency translations are recognized in OCI and presented within equity in the foreign currency translation reserve. When a foreign operation is disposed, the relevant exchange differences accumulated in the foreign currency translation reserve are transferred to the consolidated income statements as part of the profit or loss on disposal. On the partial disposal of a subsidiary that includes a foreign operation, the relevant proportion of such amount is reattributed to non-controlling interest. On disposal of a partial investment in an associate or joint venture that includes a foreign operation while retaining significant influence or joint control, the relevant proportion is reclassified to profit or loss. Net investment in a foreign operation Foreign currency gains and losses arising on translation of a monetary item receivable from or payable to a foreign operation for which settlement is neither planned nor likely to occur in the foreseeable future are considered to form part of a net investment in the foreign operation. Such gains and losses are recognized in OCI and presented within equity in the foreign currency translation reserve.
Revenue recognition [Policy Text Block]	(c) Revenue recognition: Revenue from the sale of goods is measured at the fair value of the consideration received or receivable, net of treatment and refining charges. Revenue from the sale of by-products is included within revenue. Revenue is recognized when control of the goods sold has been transferred to the customer. Control is deemed to have passed to the customer when significant risk and reward of the product has passed to the customer, Hudbay has a present right to payment, and physical possession of the product has been transferred to the customer. Sales of doré are recorded when a trade confirmation is duly signed and executed between Hudbay and the end purchaser. Sale of concentrate and finished zinc frequently occur under the following terms, and management has assessed these terms in order to determine timing of transfer of control and revenue recognition as generally outlined in the following table. Incoterms used by Hudbay Revenue recognized when goods: Cost, Insurance and Freight (CIF) Are loaded on board the vessel Free on Board (FOB) Are loaded on board the vessel Delivered at place (DAP) Arrive at the named place of destination Delivered at terminal (DAT) Arrive at the named place of destination Free Carrier (FCA) Arrive at the named place of delivery Sales of copper and zinc concentrate and certain other products are provisionally priced. For these contracts, sales prices are subject to final adjustment at the end of a future period after shipment, based on quoted market prices during the quotational period specified in the contract. Revenue is recognized when the above criteria are achieved, using weight and assay results and forward market prices to estimate the fair value of the total consideration receivable. Therefore, revenue is initially recorded based on an initial provisional invoice. Subsequently, at each reporting date, until the provisionally priced sale is finalized, sales receivables are marked to market, with adjustments (both gains and losses) recorded within revenue separately as "Pricing and volume adjustments" in the notes to the consolidated financial statements and in trade and other receivables on the consolidated balance sheets. As per IFRS 15 Revenue from contracts with customers Financial Instruments Hudbay only includes in the transaction price an amount which is not highly likely to be subject to significant subsequent revenue reversal. Within sales contracts with customers, separate performance obligations may arise pertaining to the shipping of goods sold. If applicable, costs and the transaction price are allocated on a relative standalone selling basis to any separate performance obligations and are recognized over the period of time the goods sold are shipped, on a gross basis. Hudbay recognizes deferred revenue in the event it receives payments from customers before a sale meets criteria for revenue recognition. Precious metals stream contracts, which at inception of the contract are determined that they can be satisfied through the delivery of Hudbay's own production of non-financial items (i.e. gold and silver credits) rather than cash or other financial assets, are accounted for as deferred revenue. If settlement with Hudbay's own production of gold and silver is not possible, the stream transaction is recognized as a financial liability since settlement may require a cash payment. This would cause a change to the accounting treatment, resulting in the revaluation of the agreement to the fair value through the consolidated income statements on a recurring basis. Deferred revenue associated with precious metals stream contracts are subject to variable consideration and contain a significant financing component since funds were received in advance of the delivery of concentrate. When a significant financing component is recognized, finance expense will be higher and revenues will be higher as the larger deferred revenue balance is amortized to revenues. A market-based discount rate is utilized at the inception of each of the respective stream agreements to determine a discount rate for computing the interest charges for the significant financing component of the deferred revenue balance. As product is delivered, the deferred revenue amount including accreted interest will be drawn down. The draw down rate requires the use of proven and probable reserves and certain resources in the calculation that are beyond proven and probable reserves which management is reasonably confident will be transferable to reserves. Key estimates used in determining the significant financing component include the discount rate and the reserve and resources assumed for conversion.
Cost of sales [Policy Text Block]	(d) Cost of sales: Cost of sales consists of those costs previously included in the measurement of inventory sold during the period, as well as certain costs not included in the measurement of inventory, such as the cost of warehousing and distribution to customers, provisional pricing adjustments related to purchased concentrates, profit sharing, royalty payments, share-based compensation expense and other indirect expenses related to producing operations. Cost of sales also include non-cash net realizable value adjustments to inventory, one-time adjustments related to overheads incurred when not operating at normal capacity and one-time labour charges related to facilitating the production of inventories for past service pension costs, curtailment gains and severance.
Cash and cash equivalents [Policy Text Block]	(e) Cash and cash equivalents: Cash and cash equivalents include cash, demand deposits and short-term, highly liquid investments that are readily convertible to known amounts of cash and are subject to an insignificant risk of changes in value. Cash equivalents have maturities of three months or less at the date of acquisition. Interest earned is included in finance income on the consolidated income statements and in investing activities on the consolidated statements of cash flows. Amounts that are restricted from being used for at least twelve months after the reporting date or are not available for general disbursement, like a debt service account are classified as non-current assets and presented in other financial assets on the consolidated balance sheets. Changes in restricted cash balances are classified as investing or financing activities on the consolidated statements of cash flows.
Inventories [Policy Text Block]	(f) Inventories: Inventories consist of stockpiles, finished goods inventory (concentrates and metals), materials and supplies. Concentrates, doré, metals and all other saleable products are valued at the lower of cost and estimated net realizable value. Net realizable value represents the estimated selling price for inventories less all estimated direct and indirect costs of completion and costs necessary to make the sale. Where the net realizable value is less than cost, the difference is charged to the consolidated income statements as an impairment charge in cost of sales. Costs associated with stripping activities in an open pit mine are capitalized to inventory and recorded through cost of sales unless the stripping activity can be shown to improve access to further quantities of ore that will be mined in future periods, in which case, the stripping costs are capitalized to property, plant and equipment. Cost of production of concentrate inventory is determined on a weighted average cost basis and the cost of production of finished metal inventory is determined using the first in first out basis. The cost of production includes direct costs associated with conversion of production inventory based on normal production capacity: material, labour, contractor expenses, purchased concentrates, and an attributable portion of production overheads and depreciation of all property, plant and equipment involved with the mining and production process. Hudbay measures in-process inventories based on assays of material received at metallurgical plants and estimates of recoveries in the production processes. Due to significant uncertainty associated with volume and metal content, immaterial costs are not allocated to routine operating levels of stockpiled ore. Estimates and judgements are required to assess the nature of any significant changes to levels of ore stockpiles and determining whether allocation of costs is required. Supplies are valued at the lower of average cost and net realizable value.
Exploration and evaluation expenditures [Policy Text Block]	(g) Exploration and evaluation expenditures: Exploration and evaluation activity begins when Hudbay obtains legal rights to explore a specific area and involves the search for mineral reserves, the determination of technical feasibility, and the assessment of commercial viability of an identified resource. Expenditures incurred in the exploration and evaluation phase include the cost of acquiring interest in mineral rights, licenses and properties and the costs of Hudbay's exploration activities, such as researching and analyzing existing exploration data, gathering data through geological studies, exploratory drilling, trenching, sampling, and certain feasibility studies. Hudbay expenses the cost of its exploration and evaluation activities and capitalizes the cost of acquiring interest in mineral rights, licenses and properties in business combinations, asset acquisitions or option agreements. Amounts capitalized are recognized as exploration and evaluation assets and presented in property, plant and equipment. Exploration and evaluation assets acquired as a result of an asset acquisition or option agreement are initially recognized at cost, and those acquired in a business combination are recognized at fair value on the acquisition date. They are subsequently carried at cost less accumulated impairment. No depreciation is charged during the exploration and evaluation phase. Hudbay expenses the cost of subsequent exploration and evaluation activity related to acquired exploration and evaluation assets. Cash flows associated with acquiring exploration and evaluation assets are classified as investing activities in the consolidated statements of cash flows; those associated with exploration and evaluation expenses are classified as operating activities. Judgement is required in determining whether the respective costs are eligible for capitalization where applicable, and whether they are likely to be recoverable, which may be based on assumptions about future events and circumstances. Estimates and assumptions made may change if new information becomes available. Hudbay monitors exploration and evaluation assets for factors that may indicate their carrying amounts are not recoverable. If such indicators are identified, the Company tests the exploration and evaluation assets or their CGUs, as applicable, for impairment. Hudbay also tests for impairment when assets reach the end of the exploration and evaluation phase. Exploration and evaluation assets are transferred to capital works in progress within property, plant and equipment once the Company determines that probable future economic benefits will be generated as a result of the expenditures. Hudbay's determination of probable future economic benefit is based on management's evaluation of the technical feasibility and commercial viability of the geological properties of a given ore body based on information obtained through evaluation activities, including metallurgical testing, resource and reserve estimates and the economic assessment of whether the ore body can be mined economically. Tools that may be used to determine this include a preliminary feasibility study, confidence in converting resources into reserves and the probability that the property could be developed into a mine site. At that time, the property is considered to enter the development phase, and subsequent evaluation costs are capitalized.
Property, plant and equipment [Policy Text Block]	(h) Property, plant and equipment: Hudbay measures items of property, plant and equipment at cost less accumulated depreciation and any accumulated impairment losses. The initial cost of an item of property, plant and equipment includes its purchase price or construction costs, including import duties and non-refundable purchase taxes, any costs directly attributable to bringing the asset into operation, and for qualifying assets, borrowing costs. The initial cost of property, plant and equipment also includes the initial estimate of the cost of dismantling and removing the item and restoring the site on which it is located, the obligation which Hudbay incurs either when the item is acquired or as a consequence of having used the item during a particular period for purposes other than to produce inventories during that period. Capitalization of costs ceases once an asset is in the location and condition necessary for it to be capable of operating in the manner intended by management. At this time, depreciation commences. For a new mine, this occurs upon commencement of commercial production. Any revenues less cost to produce, earned prior to commencement of commercial production, are included in the consolidated income statements. Carrying amounts of property, plant and equipment, including right-of-use ("ROU") assets, are depreciated to their estimated residual value over the estimated useful lives of the assets or the estimated life of the related mine or plant, if shorter. Where components of an asset have different useful lives, depreciation is calculated on each separate component. Components may be physical or non-physical, including the cost of regular major inspections and overhauls required in order to continue operating an item of property, plant and equipment. Certain items of property, plant and equipment are depreciated on a unit-of-production basis. The unit-of-production method is based on proven and probable tonnes of ore reserves. There are numerous uncertainties inherent in estimating ore reserves, and assumptions that were valid at the reporting date may change when new information becomes available. The actual volume of ore extracted and any changes in these assumptions could affect prospective depreciation rates and carrying values. The carrying amount of an item of property, plant and equipment is derecognized on disposal or when no future economic benefits are expected from its use or disposal. Upon derecognition of an item of property, plant and equipment, the difference between its carrying value and net sales proceeds, if any, is presented as a gain or loss in other operating income or expense in the consolidated income statements. i. Capital works in progress consist of items of property, plant and equipment in the course of construction or mineral properties in the course of development, including those transferred upon completion of the exploration and evaluation phase. On completion of construction or development, costs are transferred to plant and equipment and/or mining properties as appropriate. Capital works in progress are not depreciated. ii. Mining properties consist of costs transferred from capital works in progress when a mining property reaches commercial production, costs of subsequent mine and exploration development, and acquired mining properties in the production stage. Mining properties include costs directly attributable to bringing a mineral asset into the state where it is capable of operating in the manner intended by management and includes such costs as the cost of shafts, ramps, track haulage drifts, ancillary drifts, pumps, electrical substations, refuge stations, ventilation raises, permanent manways, and ore and waste pass raises. The determination of development costs to be capitalized during the production stage of a mine operation requires the use of judgements and estimates such as estimates of tonnes of waste to be removed over the life of the mining area and economically recoverable reserves extracted as a result. A mining property is considered to be capable of operating in a manner intended by management when it commences commercial production based on pre-established criteria. Upon commencement of commercial production, a mining property is depreciated on a unit-of-production method. Unit-of-production depreciation rates are determined based on the related proven and probable mineral reserves and associated future development costs. Subsequent mine development costs are capitalized to the extent they are incurred in order to access reserves mineable over more than one year. Ongoing maintenance and development expenditures are expensed as incurred and included in cost of sales in profit or loss. These include ore stope access drifts, footwall and hangingwall drifts in stopes, drawpoints, drill drifts, sublevels, slots, drill raises, stope manway access raises and definition diamond drilling. iii. Plant and equipment consists of buildings and fixtures, surface and underground fixed and mobile equipment and assets under lease. Plant and equipment are depreciated on either unit-of-production or straight-line basis based on factors including the production life of assets and mineable reserves. In general, mining assets are depreciated using a unit-of-production method; equipment is depreciated using the straight-line method, based on the shorter of its useful life and that of the related mine or facility; and plants are depreciated using the straight-line method, with useful lives limited by those of related mining assets. iv. At inception of a contract, Hudbay assesses whether a contract is, or contains, a lease. A contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. The Company assesses the following criteria in the determination of whether a contract conveys the right to control the use of an identified asset: • • • ▪ ▪ The Company recognizes a ROU asset and lease liability at the lease commencement date. The initial measurement of the ROU asset is on a present value basis. This is based on the calculated lease liability plus any initial direct costs incurred, an estimate of removal or restoration costs, and any payments made prior to commencement of the lease less any lease incentives received. The right of use asset is subsequently depreciated using the straight-line method from the commencement date to the earlier of the end of the useful life of the right-of-use asset or the end of the lease term. The estimated useful lives of the right-of-use assets are determined on the same basis as those of property and equipment. In addition, the right-of-use asset is periodically reduced by impairment losses, if any, and adjusted for certain remeasurements of the lease liability. The lease liability is measured at the present value of the lease payments that are yet to be paid at the commencement date, discounted using the interest rate implicit in the lease or, if that rate cannot be easily determined, Hudbay's incremental borrowing rate. Generally, the Company uses its incremental borrowing rate as the discount rate for applicable leases. Lease payments included in the measurement of the lease liability comprise fixed payments including in substance fixed payments and variable payments that depend on an index or rate, amounts expected to be payable under a residual value guarantee and the additional costs Hudbay reasonably expects to incur due to purchase options, extension options and termination options reasonably expected to be exercised. The lease liability is measured at amortized cost using the effective interest method. It is remeasured when there is a change in the expected future cash flows of a leasing contract either due to a change in index or rate, or due to a change in terms of the contract. When the lease liability is remeasured in this way, a corresponding adjustment is made to the carrying amount of the right-of-use asset, or is recorded in profit or loss if the carrying amount of the right-of-use asset is zero. Hudbay has elected not to separate non-lease components and account for the lease and non-lease components as a single lease component for lease contracts of all asset classes. The Company has elected not to recognize ROU assets and lease liabilities for short-term leases of machinery that have a lease term of 12 months or less and leases of low-value assets. Hudbay recognizes the lease payments associated with these leases as an expense on a straight-line basis over the lease term. Hudbay does not enter into transactions where the Company acts as a lessor. The incremental borrowing rate used for new ROU leases is a key management judgement. v. • • • • ◦ ◦ • Hudbay reviews its depreciation methods, remaining useful lives and residual values at least annually and accounts for changes in estimates prospectively. vi. Commercial production is the level of activities intended by management for a mine, or a mine and mill complex, to be capable of operating in the manner intended by management. Hudbay considers a range of factors when determining the level of activity that represents commercial production for a particular project, including a predetermined percentage of design capacity for the mine and mill; achievement of continuous production, ramp-ups, or other output; or specific factors such as recoveries, grades, or inventory build-ups. In a phased mining approach, management may consider achievement of specific milestones at each phase of completion. In a non-phased mining approach, management considers average actual metrics that are at least 60% of average design capacity or plan over a continuous period. Management assesses the operation's ability to sustain production over a period of approximately one to three months, depending on the complexity related to the stability of continuous operation. Commercial production is considered to have commenced, and depreciation expense is recognized, at the beginning of the month after criteria have been met. vii. The Company capitalizes borrowing costs that are directly attributable to the acquisition, construction or production of qualifying assets, which are assets that necessarily take a substantial period of time, generally one year or more, to get ready for their intended use or sale. Capitalization of borrowing costs ceases once the qualifying assets commence commercial production or are otherwise ready for their intended use or sale. Where funds are borrowed specifically to finance a project, the amount capitalized represents the actual borrowing costs incurred. Where the funds used to finance a project form part of general borrowings, the amount capitalized is calculated using a weighted average of interest rates applicable to relevant general borrowings of Hudbay during the period, to a maximum of actual borrowing costs incurred. Investment income earned by temporarily investing specific borrowings pending their expenditure on qualifying assets is deducted from the borrowing costs eligible for capitalization. Capitalization of interest is suspended during extended periods in which active development is interrupted. All other borrowing costs are recognized in the consolidated income statements in the period in which they are incurred. viii. Costs associated with stripping activities in an open pit mine are capitalized to inventory and recorded through cost of sales unless the stripping activity can be shown to improve access to further quantities of ore that will be mined in future periods, in which case, the stripping costs are capitalized to property, plant and equipment. Capitalized stripping costs are included in "mining properties" within property, plant and equipment. Capitalized stripping costs are depreciated using a units-of-production method over the expected reserves within a given phase of mine development.
Impairment of non-financial assets [Policy Text Block]	(i) At the end of each reporting period, Hudbay reviews the carrying amounts of property, plant and equipment, exploration and evaluation assets and intangible assets - computer software to determine whether there is any indication of impairment. If any such indication exists, the Company estimates the recoverable amount of the asset in order to determine the extent of the impairment loss, if any. Hudbay generally assesses impairment at the level of CGUs, which are the smallest identifiable groups of assets that generate cash inflows that are largely independent of cash inflows from other assets. Hudbay's CGUs consist of Manitoba, British Columbia, Peru, Arizona and greenfield exploration assets. The Company allocates near mine exploration and evaluation assets to CGUs based on their operating segment, geographic location and management's intended use for the property. Near mine exploration and evaluation assets are allocated to CGUs separate from those containing producing or development-phase assets, except where such exploration and evaluation assets have the potential to significantly affect the future production of producing or development-phase assets. Goodwill is tested for impairment annually and whenever there is an indication that the asset may be impaired. The Company performs goodwill impairment tests on an annual basis as at December 31 each year. If the carrying value of the CGU or group of CGUs to which goodwill is assigned exceeds its recoverable amount, an impairment loss is recognized. Goodwill impairment losses are recorded in the consolidated income statements and they are not subsequently reversed. Where an indicator of impairment exists, a formal estimate of the recoverable amount of the asset or CGU is made. The recoverable amount is the higher of the fair value less costs of disposal and value in use: - - Hudbay estimates future cash flows based on estimated future recoverable mine production, expected sales prices (considering current and historical commodity prices, price trends and related factors), production levels and cash costs of production, all based on detailed engineering LOM plans. Future recoverable mine production is determined from reserves and resources after taking into account estimated dilution and recoveries during mining, and estimated losses during ore processing and treatment. Estimates of recoverable production from measured, indicated and inferred mineral resources not included in the LOM plan are assessed for economic recoverability and may also be included in the valuation of fair value less costs of disposal. Gains from the expected disposal of assets are not included in estimated future cash flows. Assumptions underlying future cash flow estimates are subject to risks and uncertainties. Changes in estimates may affect the expected recoverability of the Company's investments in mining properties. If the carrying amount of an asset or CGU exceeds its recoverable amount, the carrying amount is reduced to the recoverable amount, and an impairment loss is recognized in the consolidated income statements in the expense category consistent with the function of the impaired asset or CGU. Hudbay presents impairment losses on the consolidated income statements as part of results from operating activities. Impairment losses recognized in respect of a CGU are allocated first to reduce the carrying amount of any goodwill allocated to the CGU and then to reduce the carrying amounts of other assets in the CGU on a pro-rata basis for depreciable assets. The Company assesses previously recognized impairment losses each reporting date for any indications that the losses have decreased or no longer exist. Such an impairment loss is reversed, in full or in part, if there have been significant changes with a positive effect on the estimates used to determine the recoverable amount. An impairment loss is reversed only to the extent that the asset's carrying amount does not exceed the carrying amount that would have been determined, net of depreciation or amortization, if no impairment loss had been recognized for the asset in prior years. Such reversals of impairment losses are recognized in the consolidated income statements. An impairment loss recognized in relation to goodwill is not reversed for subsequent increases in the recoverable amount.
Pension and other employee benefits [Policy Text Block]	(j) Hudbay has non-contributory and contributory defined benefit programs for the majority of its Canadian employees. The defined benefit pension benefits are based on years of service and final average salary for the salaried plans and are based on a flat dollar amount combined with years of service for the hourly plans. The Company provides non pension health and other post-employment benefits to certain active employees and pensioners (post-employment benefits) and also provides disability income, health benefits and other post-employment benefits to hourly and salaried disabled employees (other long-term employee benefits). Hudbay accrues its obligations under the defined benefit plans as the employees render the services necessary to earn the pension and post-employment benefits. The actuarial determination of the accrued benefit obligations for pensions and post-employment benefits uses the projected benefit method pro-rated on service (which incorporates management's best estimate of future salary levels, other cost escalation, retirement ages of employees and other actuarial factors). For other long-term employee benefits, the Company recognizes the full cost of the benefit obligation at the time the employee becomes disabled. Actuarial advice is provided by external consultants. For the funded defined benefit plans, Hudbay recognizes the deficit or excess of the fair value of plan assets over the present value of the defined benefit obligation as a liability or an asset in the consolidated balance sheets. However, the Company recognizes an excess of assets only to the extent that it represents a future economic benefit which is available in the form of refunds from the plan or reductions in future contributions to the plan. When these criteria are not met, it is not recognized but is disclosed in the notes to the consolidated financial statements. Impacts of minimum funding requirements in relation to past service are considered when determining the balance sheet position. Defined benefit costs are categorized as follows: - - - The first two components of defined benefit costs shown above are recognized in the consolidated income statements. Past service cost as well as curtailment gains are recognized in the consolidated income statements in the period of a plan amendment. Net interest is calculated by applying the discount rate at the beginning of the period to the net defined benefit liability or asset. Purchases and sales of plan assets are recorded on settlement date. Remeasurement, comprising actuarial gains and losses, the effect of changes to the asset ceiling (if applicable) and the return on plan assets (excluding interest), is reflected immediately in the consolidated balance sheets with a gain or loss recognized in OCI in the period in which they occur. Remeasurement recognized in OCI is reflected in the remeasurement reserve and will not be reclassified to the consolidated income statements. For the other long-term employee benefits plan, remeasurements are recognized immediately in the consolidated income statements. Actuarial determinations used in estimating obligations relating to these plans incorporate assumptions using management's best estimates of factors including plan performance, salary escalation, retirement dates of employees and healthcare cost escalation rates. Due to the complexity of the valuation, the underlying assumptions and its long-term nature, a defined benefit obligation is highly sensitive to changes in these assumptions. All assumptions are reviewed at each reporting date. In determining the appropriate discount rate, management considers the interest rates on corporate bonds in the respective currency with at least an AA rating, with extrapolated maturities corresponding to the expected duration of the defined benefit obligation. The mortality rate is based on publicly available mortality tables for the specific country. Future salary increases and pension increases are based on expected future inflation rates for the respective country. Hudbay also has defined contribution plans providing pension benefits for certain of its salaried employees and certain of its US employees utilizing 401K plans. The Company recognizes the cost of the defined contribution plans based on the contributions required to be made during each period. Termination benefits are recognized as an expense when Hudbay is committed demonstrably, without realistic possibility of withdrawal, to a formal detailed plan to either terminate employment before the normal retirement date, or to provide termination benefits as a result of an offer made to encourage voluntary redundancy. Termination benefits for voluntary redundancies are recognized as an expense if the Company has made an offer of voluntary redundancy, it is probable that the offer will be accepted, and the number of acceptances can be estimated reliably. Benefits that are payable more than one year after the reporting period are discounted to their present value.
Environmental and other provisions [Policy Text Block]	(k) Provisions are recognized when Hudbay has a present obligation (legal or constructive) as a result of a past event, it is probable that an outflow of resources will be required to settle the obligation, and a reliable estimate can be made. The provisions are recorded as management's best estimate of the amount required to settle an obligation. Provisions are stated at their present value, which is determined by discounting the expected future cash flows at a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the liability. Decommissioning, restoration and similar liabilities Provisions are recorded for legal and constructive obligations associated with the future costs of rehabilitating the Company's current and previous operating and development sites. Such costs are associated with decommissioning and restoration activities such as dismantling and removing structures, rehabilitating mines and tailings, and reclamation and re-vegetation of affected areas. The present value of estimated costs is recorded in the period in which the asset is installed or the environment is disturbed and a reasonable estimate of future costs and discount rates can be made. The provision is discounted using a risk-free rate, and estimates of future cash flows are adjusted to reflect risk. Subsequent to the initial measurement, the obligation is adjusted to reflect the passage of time and changes in the estimated future cash flows underlying the obligation. The increase in the provision due to the passage of time is recognized as finance expense, whereas increases and decreases due to changes in the estimated future cash flows, which are not the result of current inventory production, are capitalized and depreciated over the life of the related operating asset. Actual costs incurred upon settlement of the site restoration obligation are charged against the provision to the extent the provision was established for those costs. Upon settlement of the liability, a gain or loss may be recorded. For closed sites, changes to estimated costs are recognized immediately in the consolidated income statements within other expenses. Hudbay assesses the reasonableness of its estimates and assumptions each year and when conditions change, the estimates are revised accordingly. Judgement is required to determine the scope and timing of future decommissioning and restoration activities, as well as best available estimates and assumptions including discount rates, expected timing of decommissioning and restoration costs, inflationary factors and market risks. Changes in cost estimates, which may arise from changes in technology and pricing of the individual components of the cost may result in offsetting changes to the asset and liability and corresponding changes to the associated depreciation and finance costs. In view of the uncertainties concerning these future obligations, the ultimate timing and cost of reclamation and mine closure may differ materially from these estimates. If the change in estimate results in a significant increase in the decommissioning liability and therefore an addition to the carrying value of the asset, the Company considers whether this is an indication of impairment of the asset as a whole and, if so, tests for impairment in accordance with IAS 36, Impairment of non-financial assets In view of the uncertainties concerning environmental remediation, the ultimate cost of decommissioning and restoration liabilities could differ materially from the estimated amounts provided. The estimate of the total liability is subject to change based on amendments to laws and regulations and as new information concerning Hudbay's operations becomes available. Future changes, if any, to the estimated total liability as a result of amended requirements, laws, regulations and operating assumptions, as well as discount rates, may be significant and would be recognized prospectively as a change in accounting estimate, when applicable. Environmental laws, regulations and technology are continually evolving in all regions in which the Company operates. Hudbay is not able to determine the impact, if any, of environmental laws, regulations and technology that may be enacted in the future on its results of operations or financial position due to the uncertainty surrounding the ultimate form that such future laws and regulations may take. Onerous contracts A contract is considered to be onerous when the unavoidable costs of meeting obligations under the contract exceed the economic benefits expected to be received under it. Hudbay records a provision for any onerous contracts at the lesser of costs to comply with a contract and costs to terminate it. Restructuring provisions A provision for restructuring is recognized when management, with appropriate authority within Hudbay, has approved a detailed and formal restructuring plan, and the restructuring has either commenced or has been announced publicly. Future operating costs are not provided for.
Financial instruments [Policy Text Block]	(l) Non-derivative financial instruments are initially recognized at fair value plus, in the case of a financial asset or financial liability not measured at fair value through profit or loss, directly attributable transaction costs. Measurement in subsequent periods depends on the financial instrument's classification. Hudbay uses trade date accounting for regular way purchases or sales of financial assets. The Company determines the classification of its financial instruments and non-financial derivatives at initial recognition. Financial assets and liabilities are offset and the net amount presented in the consolidated balance sheets when, and only when, Hudbay has a legal right to offset the amounts and intends either to settle on a net basis or to realize the asset and settle the liability simultaneously. The classification of financial assets is based on the results of the contractual characteristics test and the business model assessment which will result in the financial asset being classified as either: amortized cost, fair value through profit or loss ("FVTPL") or fair value through other comprehensive income ("FVTOCI"). i. Financial assets at fair value through profit or loss Provisionally priced copper and zinc concentrate sales receivables, warrants and investments in securities of junior mining companies are classified as financial assets at fair value through profit or loss and are measured at fair value. The gains or losses related to changes in fair value are reported in the consolidated income statements. Amortized cos Cash, certain receivables, other assets related to agreements with communities near the Peru operations, trade and other payables, long-term debt and restricted cash are classified as and measured at amortized cost and are carried at amortized cost using the effective interest rate method, less impairment losses, if any. Non-derivative financial liabilities Accounts payable and senior unsecured notes are initially recognized at fair value and subsequently accounted for at amortized cost, using the effective interest method. The amortization of senior unsecured notes issue costs is calculated using the effective interest rate method. ii. Derivatives are initially recognized at fair value when Hudbay becomes a party to the derivative contract and are subsequently re-measured to fair value at the end of each reporting period. The resulting gain or loss is recognized in the consolidated income statements immediately unless the derivative is designated and effective as a hedging instrument. Derivatives with positive fair value are recognized as assets; derivatives with negative fair value are recognized as liabilities. Derivatives contracts that are entered to economically hedge a risk exposure but are not designated as a hedging instrument for hedge accounting purposes, and are physically settled, are initially and subsequently measured at fair value. Subsequent movements in fair value are recognized within the revenue line item in the consolidated income statements. iii. Hudbay considers whether a contract contains an embedded derivative when it becomes a party to the contract. Derivatives embedded in other financial liabilities or other non-financial host contracts are treated as separate derivatives when their risks and characteristics are not closely related to those of the host contracts and the host contracts are not measured at FVTPL. iv. The fair value of a financial instrument is the amount for which an asset could be exchanged, or a liability settled, between knowledgeable, willing parties in an arm's length transaction. Fair values of financial instruments traded in active markets are determined based on quoted market prices, where available. Bid prices are generally used for assets held or liabilities to be issued; asking prices are generally used for assets to be acquired or liabilities held. For financial instruments not traded in an active market, fair values are determined based on appropriate valuation techniques. Such techniques may include discounted cash flow analysis, using recent arm's length market transactions, reference to the current fair value of another instrument that is substantially the same, and other valuation models. The Company applies a hierarchy to classify valuation methods used to measure financial instruments carried at fair value. Levels 1 to 3 are defined based on the degree to which fair value inputs are observable and have a significant effect on the recorded fair value, as follows: - - - Level 3: Valuation techniques use significant inputs that are not based on observable market data (unobservable inputs). An analysis of fair values of financial instruments is provided in note 30. v. Hudbay recognizes loss allowances for Expected Credit Losses ("ECL") for trade receivables not measured at FVTPL. Loss allowances for trade receivables are measured at an amount equal to lifetime ECL. ECL is a probability-weighted estimate measured at the present value of all cash shortfalls including the impact of forward-looking information. Hudbay has established a provision based on the Company's historical credit loss experience, adjusted for forward-looking factors specific to the debtors and the economic environment. vi. Hudbay derecognizes financial assets when the contractual rights to the cash flows from the assets expire, or when the Company transfers the rights to receive the contractual cash flows on the financial assets in a transaction in which substantially all the risks and rewards of ownership of the financial asset are transferred. Any interest in the transferred financial assets that is created or retained by Hudbay is recognized as a separate asset or liability. Hudbay derecognizes financial liabilities when its contractual obligations are discharged, cancelled or expire or when its terms are modified and the cash flows of the modified liability are substantially different.
Taxation [Policy Text Block]	(m) Taxation: Current Tax Current income tax assets and liabilities for the current and prior periods are measured at the amount expected to be recovered from or paid to the taxation authorities. The tax rates and tax laws used to compute the amount are those that are enacted or substantively enacted by the balance sheet date. Hudbay is subject to income taxes in numerous jurisdictions. Significant judgement is required in determining the worldwide provision for income taxes due to the complexity of legislation. There are many transactions and calculations for which the ultimate tax determination is uncertain during the ordinary course of business. The Company recognizes liabilities for anticipated tax issues based on estimates of whether additional taxes will be due. Where the final tax outcome of these matters is different from the amounts that were initially recorded, such differences will affect the income tax and deferred tax provisions in the period in which such determination is made. Additionally, future changes in tax laws in the jurisdictions in which Hudbay operates could limit the ability of the Company to obtain tax deductions in future periods. Deferred Tax Deferred tax is recognized using the balance sheet method in respect of temporary differences at the balance sheet date between the tax basis of assets and liabilities, and their carrying amounts for financial reporting purposes. Deferred income tax liabilities are recognized for all taxable temporary differences, except: - - Deferred income tax assets are recognized for all deductible temporary differences, carry-forward of unused tax assets and unused tax losses, to the extent that it is probable that taxable profit will be available against which the deductible temporary differences, and the carry-forward of unused tax assets and unused tax losses can be utilized, except: - - To the extent that it is probable that taxable profit will be available to offset the deductible temporary differences, Hudbay recognizes the deferred tax asset regarding the temporary difference on decommissioning, restoration and similar liabilities and recognizes the corresponding deferred tax liability regarding the temporary difference on the related assets. The carrying amount of deferred income tax assets is reviewed at each balance sheet date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred income tax asset to be utilized. Unrecognized deferred income tax assets are reassessed at each balance sheet date and are recognized to the extent that it has become probable that future taxable profit will be available to allow the deferred tax asset to be recovered. Judgement is required in determining whether deferred tax assets are recognized on the consolidated balance sheets. Deferred tax assets, including those arising from unutilized tax losses, require management to assess the likelihood of taxable profit in future periods in order to utilize recognized deferred tax assets. Estimates of future taxable income are based on forecast cash flows from operations and the application of existing tax laws in each jurisdiction. To the extent that future cash flows and taxable income differ significantly from estimates, the ability to realize the net deferred tax assets recorded at the balance sheet date could be affected. Deferred tax is measured on an undiscounted basis at the tax rates that are expected to apply in the periods in which the asset is realized or the liability is settled, based on tax rates and tax laws enacted or substantively enacted at the balance sheet date. Deferred income tax assets and deferred income tax liabilities are offset if a legally enforceable right exists to offset current tax assets against current tax liabilities and the deferred income taxes relate to the same taxable entity and the same taxation authority. Current and deferred taxes relating to items recognized outside profit or loss (whether in other comprehensive income or directly in equity) are recognized outside profit or loss and not in the consolidated income statements. Mining taxes and royalties are treated and disclosed as current and deferred taxes if they have the characteristics of an income tax.
Share capital and reserves [Policy Text Block]	(n) Share capital and reserves: Transaction costs Transaction costs directly attributable to equity transactions are recognized as a deduction from equity. Other capital reserve The other capital reserve is used for equity-settled share-based compensation and includes amounts for stocks options granted and not exercised. Foreign currency translation reserve The foreign currency translation reserve is used to record exchange differences arising from the translation of the financial statements of foreign operations. Exchange differences arising from the translation of the financial statements of foreign operations form part of the net investment in the foreign operation. Translation gains and losses remain in the reserve until disposal of all or a portion of the foreign operation.
Flow-through shares [Policy Text Block]	(o) Resource expenditure deductions for income tax purposes related to exploration activities funded by flow-through share arrangements are renounced to investors under Canadian income tax legislation. On issuance, the Corporation separates the flow-through share into i) a flow-through share premium, equal to the difference between the current market price of the Corporation's common shares and the issue price of the flow-through share and ii) share capital. Upon qualifying exploration and/or development expenditures being incurred, the sale of tax deductions is recognized as other income in the income statement and the related liability is reduced. The Company may also be subject to a Part XII.6 tax on flow-through proceeds renounced, in accordance with the Canadian Income Tax Act flow-through regulations. When applicable, the estimated tax payable is accrued until paid.
Share-based compensation [Policy Text Block]	(p) Hudbay compensates its employees in part through the use of a Deferred Share Unit ("DSU") plan for non-employee members of the Board of Directors, a Restricted Share Unit ("RSU") plan for employees, a Performance Share Unit ("PSU") plan for employees and a stock option plan for employees. These plans are included in provisions on the consolidated balance sheets and further described in note 27. Changes in the fair value of the liabilities are recorded in the consolidated income statements. Cash-settled transactions, consisting of DSUs, RSUs and PSUs, are initially measured at fair value and recognized as an obligation at the grant date. The liabilities are remeasured to fair value at each reporting date up to and including the settlement date, with changes in fair value recognized in the consolidated income statements. Hudbay values the liabilities based on the change in the Company's share price. Additional DSUs, RSUs and PSUs are credited to reflect dividends paid on Hudbay common shares over the vesting period. The current portion of the liability reflects those grants that have vested or that are expected to vest within twelve months. DSUs vest on the grant date and are redeemable when a participant is no longer a member of the Board of Directors. Issue and redemption prices of DSUs are based on the average closing price of the Company's common shares for the five trading days prior to issuance or redemption. RSUs and PSUs are issued under Hudbay's Long Term Equity Plan ("LTEP Plan") and vest on or before the third anniversary of the grant. RSUs and PSUs granted under the LTEP Plan may be settled in the form of the Company's common shares or, at the option of Hudbay, the cash equivalent based on the market price of the common shares as of the vesting date. Hudbay has historically settled RSUs in cash. Except in specified circumstances, RSUs and PSUs terminate when an employee ceases to be employed by the Company. Valuations of RSUs and PSUs reflect estimated forfeitures. Equity-settled transactions with employees relate to stock options and are measured by reference to the fair value at the earlier of the grant date and the date that the employee unconditionally became entitled to the award. Fair value is determined using a Black-Scholes option pricing model, which relies on estimates of the future risk-free interest rate, future dividend payments, future share price volatility and the expected average life of the options. Hudbay believes this model adequately captures the substantive features of the option awards and is appropriate to calculate their fair values. The fair value determined at the grant date is recognized over the vesting period in accordance with vesting terms and conditions, with a corresponding increase to other capital reserves. The amount recognized as an expense is adjusted to reflect the number of awards for which the related service and non-market vesting conditions are expected to be met.
Earnings per share [Policy Text Block]	(q) Earnings per share: The Company presents basic and diluted earnings (loss) per share ("EPS") data for its common shares. Basic EPS is calculated by dividing the profit or loss attributable to common shareholders of the Company by the weighted average number of common shares outstanding during the period. Diluted EPS is determined by adjusting the profit or loss attributable to common shareholders and the weighted average number of common shares outstanding for the effects of all dilutive potential common shares, which previously consisted of stock options granted to employees and warrants. When calculating earnings per share for periods where the Company has a loss, Hudbay's calculation of diluted earnings per share excludes any incremental shares from the assumed conversion of stock options as they would be anti-dilutive.
Leases [Policy Text Block]	(r) Leases: Leases, under which substantially all the risks and rewards incidental to ownership of the leased item are transferred to Hudbay, are capitalized as assets at the inception of the lease at the lower of fair value or the present value of the minimum lease payments. Lease payments are apportioned between finance charges and the reduction of the liability so as to achieve a constant periodic rate of interest on the remaining balance of the liability. Finance charges are reflected in the consolidated income statements as finance costs. Non-ROU lease payments are recognized as an expense in the consolidated income statements on a straight-line basis over the lease term.
Segment reporting [Policy Text Block]	(s) Segment reporting: An operating segment is a component of the Company that engages in business activities from which it may earn revenue and incur expenses and for which discrete financial information is available. Hudbay's chief executive officer regularly reviews the operating results of each operating segment to make decisions about resources to be allocated to the segment and assess its performance. In determining operating segments, Hudbay considers location and decision-making authorities. Refer to note 35.
