◾	2QFY23:

Highest-ever second quarter mined metal production at 255,000 tonnes, increased 3% YoY, driven by better grades and improved mill recoveries. Sequential growth of 1% QoQ was largely on account of better grades.

Refined metal production at 246,000 tonnes, an increase of 18% YoY with improved smelter performance, better mined metal availability and base impact due to extended maintenance shutdown in the same period last year. However, refined metal was lower by 6% QoQ due to lower roaster availability owing to breakdown of an acid storage tank at Chanderiya plant in 2QFY23 and time taken in ramp up of production post maintenance.

Integrated zinc production was at 189,000 tonnes, up 16% YoY and down 8% QoQ. Refined lead production was 57,000 tonnes, up 21% YoY and 5% QoQ. Saleable silver production was 194 tonnes, up 28% YoY and 10% QoQ in line with lead metal production and WIP liquidation.

◾	1HFY23:

First half mined metal production at 507,000 tonnes was higher by 8% YoY, on account of increase in ore production, further supported by better grades & improved operational efficiency.

		Production Release for the Second Quarter and Half Year ended 30^th September 2022

First half refined metal production at 506,000 tonnes, was up 13% YoY, resulting from consistent mined metal flow from mines and better plant availability partly offset by acid storage tank breakdown at Chanderiya plant in 2QFY23.

1HFY23 integrated zinc production was at 395,000 tonnes, up 13% YoY and refined lead production was at 110,000 tonnes, up 16% YoY. Saleable silver production was 371 tonnes, up 19% YoY in-line with lead metal production.

◾	2QFY23:

Overall production increased by 35% YoY and 9% QoQ to 74,000 tonnes in line with ramp-up at Gamsberg.

Gamsberg registered 43%YoY and 4% QoQ production growth to achieve quarterly production of 55,000 tonnes; supported by higher tonnes treated and higher Zinc recoveries.

BMM production was up 16% YoY supported by higher lead grades and 25%QoQ in line with higher throughput and Lead grades.

◾	1HFY23:

Overall production increased by 22% YoY to 141,000 tonnes with higher Zinc recoveries at Gamsberg.

Gamsberg production was higher by 27% YoY at 108,000 tonnes, mainly attributable to higher throughput, ore grade and Zinc recoveries.

BMM production was higher by 8% YoY at 33,000 tonnes, resulting from higher grade of Lead.

Tuticorin Smelting operations remain halted since April 2018. The Tamil Nadu Pollution Control Board (TNPCB), through an order dated 9th April 2018, rejected the Consent to Operate (CTO) for the Plant and issued a direction for closure and disconnection of power supply at the plant. In May 2018, the Government of Tamil Nadu issued orders with a direction to permanently seal the existing copper smelter plant at Tuticorin. The matter is currently under sub judice before the Supreme Court and next hearing is yet to be notified.
