Hindustan Zinc Ltd delivered its highest ever mined metal production of 1.114 million tonnes in 2025-26, according to a company statement. The mining company achieved this milestone while simultaneously expanding its resource base through aggressive exploration activities. The company's ore reserves increased nearly 16% year-on-year to a record 219.1 million tonnes from 189.1 million tonnes in 2024-25, demonstrating strong operational performance and resource management capabilities.
The company completed 464.32 kilometres of exploration drilling during 2025-26, with 88.08% of drill holes intersecting mineralisation, as reported by UdaipurTimes. Hindustan Zinc added 32 million tonnes of gross ore resources and reserves during the year, bringing total resources and reserves to an all-time high of 468.6 million tonnes. This expansion provides visibility for more than 25 years of mine life and strengthens long-term raw material security for the company's planned expansion plans.
The company's metal reserves stood at 13.9 million tonnes at the end of 2025-26, the highest since its transition to underground mining, according to the statement. For a mining business operating at scale, exploration is central not only to replacing the ore extracted each year but also to creating additional inventory for future growth. Hindustan Zinc's sustained additions alongside record mining demonstrate the ability of its existing asset base to continue generating new resource potential.
