Hindustan Zinc, on Thursday, said that the company is gradually expanding its resource footprint through its exploration subsidiary and is making a calibrated move into critical minerals beyond the core portfolio of zinc, lead, and silver, Chairperson Priya Agarwal Hebbar said in a letter to shareholders.

Priya Agarwal Hebbar emphassed on Hindustan Zinc’s low-cost leadership, record third-quarter operational and financial performance, and the growing contribution of silver to profitability amid higher prices. She stated that initiatives such as the proposed Zinc Park, Hindustan Zinc’s calibrated entry into critical minerals with a tungsten exploration licence, and the role of technology in improving safety and efficiency are all progressing well.

Hindustan Zinc delivered its highest-ever third-quarter mined metal production since the underground transition in the third quarter and also delivered a record third-quarter refined metal production. The company said in a statement that it produced 276 kt of mined metal and achieved a record 270 kt of refined metal.

“For the first time in our company's history, quarterly revenue crossed ₹10,000 crore, reaching ₹10,980 crore-up 28% from the previous quarter,” she said.

“Our EBITDA hit an all-time high of 16,087 crore with a 55% margin, and profit after tax grew to 13,916 crore, up 48% quarter-on-quarter and 46% year-on-year. These outcomes reinforce our confidence in the strength of our integrated operating model and the disciplined way the business is being managed,” she added.

Priya Agarwal Hebbar also highlighted Hindustan Zinc’s ongoing efforts to maintain cost leadership in silver. “What makes me particularly proud is that we achieved this while reducing our cost of production by approximately 10% year-on-year. At around $940 per tonne, our zinc production cost remains among the lowest globally. In uncertain times, this discipline gives us resilience.”

“Silver emerged as a significant part of our story this quarter, reflecting its growing importance across clean energy, electronics and advanced manufacturing. Hindustan Zinc produced 158 metric tonnes of silver during the third quarter and with higher silver prices, the precious metal's contribution rose to 44% of the overall profitability,” she said.

Hindustan Zinc is focusing on technology, which is helping the company in advancing its priorities. “Automation, real-time monitoring and data-led decision-making increasingly supported improvements in safety, resource efficiency and environmental performance across our mines and smelters. These aren't just tools-they're enabling us to keep the promises we make to our employees and communities,” Priya Agarwal Hebbar said.

Hindustan Zinc is consciously evolving from a zinc-silver major into a diversified multi-metal and critical minerals company. “This quarter tested that strength across volatile markets and shifting global dynamics, and I'm proud to share that Hindustan Zinc rose to meet the moment. What emerged was not just resilience, but a clearer vision of what Hindustan Zinc is becoming: a multi-metal enterprise built for the next industrial era, anchored in operational excellence and energized by purpose.” she said.
