Hindustan Zinc, the world’s largest integrated zinc producer, reported record-breaking production figures for the fourth quarter and full financial year ending March 31, 2025. The company achieved its highest-ever annual mined metal production of 1,095 kilotonnes (kt), driven by improved ore grades and higher recovery rates at its mills. Refined metal production also reached an all-time high of 1,052 kt, supported by enhanced plant availability and operational efficiency. The company continues to hold the highest market capitalization among global zinc producers. In FY25, mined metal production was recorded at 1,095 kt, supported by improved grades and better recovery at processing units. Refined metal production totaled 1,052 kt, with refined zinc output reaching 827 kt, marking a 1 per cent increase, while refined lead production rose to 225 kt, a 4 per cent growth. Hindustan Zinc Alloys, a wholly owned subsidiary, contributed 10 kt of zinc alloys, further strengthening the company’s Value-Added Product (VAP) segment. Saleable silver production stood at 687 metric tonnes, reflecting an 8 per cent decline due to changes in mining sequences and lower silver output from the SK mine. During the fourth quarter of FY25, Hindustan Zinc recorded its highest-ever quarterly mined metal production at 310 kt, marking a 17 per cent sequential increase, supported by higher ore grades and increased output from the Agucha and Zawar mines. Refined metal production stood at 270 kt, reflecting a 4 per cent increase from the previous quarter. Zinc production rose to 214 kt, a 5 per cent increase, while lead production increased by 2 per cent to reach 56 kt. Saleable silver production for the quarter was 177 metric tonnes, up 10 per cent quarter-on-quarter, driven by higher lead output and improved work-in-progress liquidation. Additionally, wind power generation for the quarter reached 63 million units (MU), registering a 33 per cent increase due to stronger wind velocity. Hindustan Zinc’s consistent operational enhancements and focus on efficiency have positioned it as a leader in the global zinc market.
