Hindustan Zinc reports record Q1 mined metal at 265 kt; silver and refined output fall

Vedanta group firm Hindustan Zinc Limited on Wednesday (July 2) reported its production figures for the quarter ended June 30, 2025.

The company achieved its highest Q1 mined metal output at 265 kilo tonnes, marking a 1% year-on-year (YoY) increase. However, the figure declined 15% sequentially, attributed to regular mine preparation activities undertaken during the first quarter.

Refined metal production stood at 250 kilo tonnes, down 5% YoY and 7% quarter-on-quarter (QoQ). This includes 202 kilo tonnes of refined zinc and 48 kilo tonnes of refined lead, reflecting lower plant availability and scheduled maintenance. Hindustan Zinc Alloys, a wholly-owned subsidiary, delivered its highest quarterly production of 5.1 kilo tonnes during the quarter.

Silver production fell to 149 tonnes, down 11% YoY and 16% sequentially, primarily due to reduced silver input from the SK mine and a higher work-in-progress liquidation base in the previous quarter. Wind power generation surged to 134 million units, up 24% YoY and 113% QoQ, driven by seasonal wind velocity patterns.

Last month, Hindustan Zinc said its board has approved initial plans to double the capacity of zinc, lead, and silver production. As part of this 2x growth plan, the company has approved expanding its integrated refined metal capacity by 250 ktpa, along with corresponding increases in mines and mills capacity.

The project is targeted for completion within 36 months, with an estimated overall cost of approximately ₹12,000 crore.

This expansion aligns with strong growth in demand both in India and globally over the next five years. The board has approved the establishment of a new 250 ktpa integrated smelter at Debari, alongside expansions in mines and mills across its operations, the company said.

Shares of Hindustan Zinc Ltd ended at ₹446.65, down by ₹3.75, or 0.83%, on the BSE.
