Hindustan Zinc Posts Highest-Ever Third-Quarter Mined and Refined Metal Output

Hindustan Zinc Ltd. reported its highest-ever mined and refined metal production for a third quarter in October-December 2025-26, supported by higher ore output, commissioning of debottlenecking projects and improved plant availability.

Mined metal production rose 4% year-on-year to 276,000 tonnes in the December quarter, while saleable metal output increased 4% to 270,000 tonnes. Refined zinc production climbed 8% to 221,000 tonnes, reflecting better operational performance. Refined lead output fell 11% year-on-year to 49,000 tonnes, largely due to lead-only pyro operations in the comparable period.

Silver production stood at 158 tonnes during the quarter, marginally lower on a year-on-year basis but up 10% sequentially in line with higher lead production. Wind power generation increased 5% year-on-year to 50 million units, tracking wind velocity trends.

For the nine months ended December, mined metal production rose 2% to a record 799,000 tonnes, aided by higher ore production, improved grades and better recoveries. Saleable metal output declined 2% year-on-year to 766,000 tonnes.

Refined zinc production for the nine-month period increased 2% to 624,000 tonnes, supported by improved plant availability. Refined lead output fell 16% to 142,000 tonnes due to lead-only pyro operations in the previous period and lower availability at pyro plants.

Silver production declined to 451 tonnes over the nine-month period, reflecting lower silver input from mines in line with the mining sequence. Wind power generation rose 11% year-on-year to 316 million units.
