_Here are the key recent updates you need to know _

• Vedanta Group firm Hindustan Zinc Ltd (HZL) in early July 2026, in its business update, said that while its mined metal production in the first quarter rose marginally by 1%, the refined lead production dropped by 2%.

The company's refined metal production grew by 4% to 2,60,000 tonnes in the April-June period, over the year-ago period.

In a filing to BSE, the company said it was the "best-ever first quarter mined metal production at 2,68,000 tonnes, driven mainly by better grades."

While the company's refined zinc production rose to 2,13,000 tonnes, refined lead production saw a drop of 2% to 47,000 tonnes.

Mined metal is the raw, unrefined metal contained within the extracted ore from the earth. Saleable metal is the final, refined product that has been processed and is ready to be sold to the market.

The saleable silver production was at 149 tonnes, and the wind power generation was at 133 million units (MU), the filing said.

"Wind power generation at 133 MU is in line with wind velocity and seasonality impact," it said.

• In June 2026, HZL announced its collaboration with Advantek Associates LLP and Aero Eagle Automobiles Pvt Ltd to evaluate green hydrogen and alternative clean-energy solutions across its operations.

The collaboration will explore adoption of innovative technologies aimed at reducing carbon emissions and enabling a transition to low-carbon, future-ready mining.

"Through this MoU (Memorandum of Understanding), Hindustan Zinc is set to pioneer the use of hydrogen fuel for underground mining applications, positioning it to become the only company to deploy this technology in such environments," the company said in a filing to BSE.

The collaboration is part of the company's larger strategy to build future-ready, low-carbon and technology-led mining operations, aligned with its commitment to become Net Zero by 2050 or sooner.

• In May 2026, Hindustan Zinc unveiled plans to generate ₹2,000 crore in value by rolling out artificial intelligence-driven solutions across its mining and manufacturing operations.

The move comes amid a broader push by mining and metals firms to adopt digital technologies to tackle rising input costs, tighten margins and meet stricter environmental, social and governance expectations.

The company revealed the target during 'Zinnovation 2026', an industry technology showcase organised with V-Spark DeepTech Ventures - a global corporate innovation, accelerator and ventures platform.

Hindustan Zin Q4 FY26 earnings

HZL reported a record profit of ₹5,033 crore for the March quarter FY26 on the back of higher zinc and silver prices and increased production.

The profit was about 68% higher from ₹3,003 crore in the year-ago January-March period. The record quarterly profit was driven by an all-time high quarterly EBITDA of ₹7,747 crore, up 61% YoY.

The company also marked the historic full year (FY26) net profit of ₹13,832 crore, up 34% YoY.

Revenue during the March quarter stood at ₹13,544 crore, up 49% YoY, driven by higher zinc and silver prices, increased production, lead concentrate sales, higher by-product realisation, and a stronger dollar. Income rose to ₹13,824 crore from ₹9,314 crore a year earlier.

The company crossed a key milestone of 1.1 million tonnes of mined metal production, as per a BSE filing.

"We also delivered a record quarterly refined metal production at the lowest cost of production of 903 dollar per tonne despite the ongoing geopolitical challenges. As we step into our 2.0 growth phase, we are strengthening our strategic roadmap. With our move into critical minerals, we are aligning with future-facing sectors while contributing meaningfully to India's growth and long-term stakeholder value," Chief Executive Officer Arun Misra said.
