Rigel Resource Acquisition (RRACF) 425Business combination disclosure

Exhibit 99.1

Aurous to go Public via Business Combination with Rigel Resource Acquisition Corp

JOHANNESBURG and NEW YORK – March 11^th, 2024 – Blyvoor Gold Resources Proprietary Limited and Blyvoor Gold Operations Proprietary Limited (together, “Aurous” or the “Target Companies”), a producing mining group which owns the Blyvoor gold mine (“Blyvoor Mine”) and the Gauta tailings retreatment project (“Gauta Tailings”), and Rigel Resource Acquisition Corp (“Rigel”) (NYSE: RRAC), a special purpose acquisition company, sponsored by a fund managed by Orion Resource Partners (“Orion”), one of the world’s foremost, mining-focused alternative investment firms, have entered, among others, into a definitive business combination agreement that will result in Aurous becoming publicly traded.

The Transaction values Aurous at a pre-money equity value of approximately $362 million. Upon completion of the proposed business combination, which is subject to customary closing conditions and regulatory approvals, the resulting company is expected to be named “Aurous Resources” and is to ultimately list on NASDAQ. Aurous and Rigel, among others, have entered into PIPE financing agreements (together with the above, the “Transaction”).

As a result of the Transaction, Aurous expects to benefit from strong gold prices, organic production growth, optimisation projects and the build-out of the Gauta Tailings project. Aurous further expects to benefit from M&A optionality and a debt-light balance sheet.

Aurous’ existing management team, led by Chief Executive Officer, Richard Floyd and Executive Chairman, Alan Smith, will continue to lead the business. Aurous’ principal asset, the Blyvoor Mine, is a producing, high-grade, long-life underground gold mine in the Witwatersrand region near Johannesburg, South Africa, one of the most prolific regions for gold production in the world.

Aurous’ Chief Executive Officer, Richard Floyd says: “This Transaction represents one of the first significant gold industry deals in South Africa in some time and is expected to enable Blyvoor to expand its underground infrastructure, enhance surface infrastructure and optimize operations by achieving economies of scale. With the support of our investors and banking partners, we expect to reach our operational targets and unlock the next stage of growth for Aurous. Since the restart of production from the Blyvoor Mine in 2022, Aurous has been able to re-employ approximately 1,500 workers who had been unemployed following closure of the mine in 2013. This Transaction and associated influx of foreign investment into South Africa has the potential to enable further meaningful job creation, continued revitalisation of the local community and recapitalization of Africa’s precious metals industry, all of which we expect will be well-received by the relevant South African authorities.”

Rigel’s Chief Executive Officer, Jon Lamb, says: “We are thrilled to combine with a cash-positive, debt-light target such as Aurous that has already achieved impressive operational milestones and is expected to deliver market-leading growth.”

Rigel’s President, Nate Abebe, notes: “Aurous offers significant long-term investment value thanks to its high-margin, high-growth and expected fully-funded mine life. We have worked diligently over a few years to find a quality business to combine with and are pleased to have arrived at this merger agreement which is expected to deliver a value-accretive transaction to all stakeholders.”

Summary of the Transaction

The Transaction values Aurous at a pre-money equity value of $362 million, implying a Price / Net Asset Value transaction multiple of 0.3x, thereby providing an attractive entry point for Rigel shareholders at a discount to other leading public gold producers. The transaction is expected to provide Aurous with no less than $50 million of capital, before payment of transaction expenses and other payments, drawn from $7.5 million of committed PIPE financing from leading institutional and strategic investors and approximately $278 million of cash in Rigel’s trust account (estimated at Transaction close and subject to redemptions by Rigel shareholders). At Transaction close, debt levels of the resulting company are expected at approximately $6 million. Net proceeds from the transaction will enable Aurous to continue to invest in improvements designed to accelerate production growth and to lower operating costs at the Blyvoor Mine, which already benefits from a first quartile production-cost position amongst comparable gold mines.

Upon closing of the transaction, Rigel’s non-redeeming shareholders are expected to receive a combination of shares in the resulting company, RRAC Newco (“NewCo”), and cash to the extent the cash in Rigel’s trust account at transaction close exceeds $10.00 per share.

The transaction, which has been unanimously approved by the boards of directors of Aurous and Rigel, is expected to close in the second half of 2024, subject to approval by Rigel shareholders, by the Financial Surveillance Department of the South African Reserve Bank and other customary closing conditions.
