o Alumina production at Lanjigarh refinery increased by 7%QoQ and 1%YoY to 503,000 tonnes.

o The cast metal aluminium production at our smelters was marginally lower on QoQ basis due to lower operating days, however, it increased 8%YoY to 572,000 tonnes.

◾ FY22:

o Achieved highest ever Alumina production of 1,968,000 tonnes with a 7%YoY increase.

o Aluminium production also touched record high of 2,268,000 tonnes with a 15%YoY increase; driven by production ramp up activities and operational efficiencies.

◾ 4QFY22:

o Achieved highest ever quarterly Mined metal production of 295,000 tonnes since underground transition. This translates into 17%QoQ and 3%YoY growth; supported by higher Ore production and better mining grades.

o Integrated metal production was up 2%YoY to 260,000 tonnes. Integrated zinc production increased 8%YoY to 211,000 tonnes. Integrated Lead production decreased 19%YoY to 49,000 tonnes as Pyro plant (at CLZS) operations was changed from Lead mode to Zinc-Lead mode. Integrated saleable silver production, in line with lower Lead production, decreased 6%QoQ and 20%YoY to 162 tonnes.

◾ FY22:

o Achieved best-ever Mined metal production, crossed 1 million mark to reach at 1,017,000 tonnes in FY22. This translated into 5%YoY growth; supported by higher ore production across the mines.

o Integrated metal production was also highest ever at 967,000 tonnes with 4%YoY growth; supported by better plant and concentrate availability. Lead production was lower on account of changing mode of Pyro plant (at CLZS) operations from Lead mode to Zinc-Lead mode. Silver production decreased 8%YoY to 647 tonnes in line with Lead metal production and reduction of silver WIP.

◾ 4QFY22:

o Overall production increased 5%QoQ to 55,000 tonnes with ramp-up at Gamsberg.

o Gamsberg registered 9%QoQ and 9%YoY production growth to achieve quarterly production of 45,000 tonnes; supported by higher throughput and ore grade.

o Black Mountain mine production was down by 11%QoQ due to lower grade and recovery of Zinc offset by better grades and recovery of Lead. On YoY basis, it was lower by 29% at 10,000 tonnes with lower grade and recovery of Zinc; partly offset by higher Lead grade.

o Skorpion mine remained under care and maintenance during the quarter.

◾ FY22:

o Overall production was higher by 10%YoY to 223,000 tonnes with ramp-up at Gamsberg.

o Gamsberg achieved highest ever annual production of 170,000 tonnes. This translates into an 18%YoY growth. Most of the bottleneck issues related to mill stability, reliability and recovery have been addressed with addition of filter press and rougher cells. During Mar’22, about 81% recovery was achieved with a 600t-650t/day production.

o Black Mountain mine production was lower by 9% to 52,000 tonnes due to lower ore grades and lower Zinc recoveries, which was partly offset by higher mine production, throughput and Lead recoveries.

o Skorpion production was NIL in FY22 as mine remained under care and maintenance.

Production Release for the 4^th Quarter and Full Year ended 31^st March 2022

◾ 4QFY22:

o Average gross operated production was 153,840 boepd.

o Rajasthan block’s average gross production was lower by 3%QoQ and 4%YoY to 132,443 boepd, mainly due to natural decline. The natural decline in the MBA fields has been partially offset by the continued gains realized from polymer injection in Bhagyam & Aishwariya fields and new infill wells brought online in Mangala, NI and ABH fields. Gross production from Development Area-1 (DA-1), Development Area-2 (DA-2) and Development Area-3 (DA-3) averaged 114,963 boepd, 17,327 boepd and 153 boepd; respectively.

o Gas production from Raageshwari Deep Gas (RDG) averaged 144.5 million standard cubic feet per day (mmscfd) (equivalent to 24.1 kboepd); Gas sales post captive consumption at 119.6 mmscfd (equivalent 19.9 kboepd).

o Ravva block’s average production was lower by 8%QoQ and 19%YoY to 13,248 boepd, mainly due to natural decline. Previous year production included gains from infill drilling campaign.

o Cambay block’s average production was higher by 2%QoQ to 8,065 boepd.

◾ FY22:

o Average gross operated production was marginally lower by 1%YoY at 160,851 boepd. Rajasthan block’s average gross production was up 4%YoY to 137,723 boepd as the natural field decline has been offset by ramp-up of gas production, infill wells in Mangala field and impact of polymer injection in Bhagyam and Aishwariya fields. Combined production from the offshore assets declined 22%YoY to 23,089 boepd with natural field decline.

o Pig Iron production was lower by 12% on QoQ basis to 1,78,000 tonnes, amidst unplanned shutdown at one of the blast furnaces in the current quarter. However, it was higher by 14% on YoY basis as last year corresponding quarter was impacted due to shutdown at one of the furnaces for relining activities.

◾ FY22:

o Karnataka Iron ore production increased 8%YoY to 5.4 million tonnes. FY21 production was impacted by nationwide COVID-19 lockdowns.
