Hindustan Zinc Limited has announced a ₹40,000–50,000 crore capital expenditure plan over the next five years to significantly expand zinc and silver production capacity and extend mine life.

The plan aims to double refined zinc capacity from 1.1 MTPA to 2 MTPA and increase silver refining capacity from 800 tonnes to 1,500 tonnes per annum. Key approved projects include a 250,000-tonne integrated zinc smelter, a tailings reprocessing plant, and expanded exploration activities, together accounting for about ₹17,000 crore of investment.

A major focus is increasing mineral reserves from 13 million tonnes to over 50 million tonnes, which is expected to extend mine life beyond 25 years. The company has also guided over $1 billion in annual capex, split between growth and maintenance.

Overall, the strategy is aimed at strengthening Hindustan Zinc’s long-term production base, supported by strong cash flows and steady demand from infrastructure and industrial sectors in India.
