Union Minister Visits Rajpura Dariba Complex

Shri G. Kishan Reddy, Hon'ble Union Minister of Coal and Mines, Government of India, visited Hindustan Zinc's Rajpura Dariba Complex in Rajasthan. The visit encompassed the Sindesar Khurd Mine — one of the world's largest silver-producing underground mines — and the Dariba Smelting Complex. During the visit, the Minister reviewed technology-led mining and smelting operations, safety systems, remote-controlled equipment, and sustainability initiatives. He also witnessed a demonstration by India's first all-women mine rescue team and reviewed flagship CSR programmes including Sakhi, Shiksha Sambal, Zinc Football, and the Unchi Udaan programme. Discussions centred on responsible mining, mineral security, and strengthening domestic value chains.

ESG Milestones: Zinc Mark Certifications and Dow Jones Index Inclusion

Hindustan Zinc achieved two landmark certifications under the globally recognised Zinc Mark framework during the period. The Chanderiya Lead Zinc Smelter became India's first Zinc Mark certified smelting site, while the Rampura Agucha Mine — the world's largest underground zinc-lead mine — became India's first Zinc Mark certified mine. These certifications validate adherence to internationally benchmarked environmental, social, and governance (ESG) standards. Additionally, Hindustan Zinc was included in the Dow Jones Best-in-Class Index 2026 for Emerging Markets, reflecting its leadership in sustainability, governance, and long-term value creation.

Strategic Partnerships and Critical Minerals Expansion

Hindustan Zinc signed an MoU with Group Nirmal to establish a zinc wire manufacturing facility at its flagship Zinc Industrial Park in Rajasthan. The facility will manufacture zinc wire using SHG zinc, catering to key sectors including infrastructure, renewable energy, automotive, and industrial engineering. In a separate development, Hindustan Zinc emerged as the successful bidder for the Jhandawali-Satipura Potash and Halite Block in Rajasthan under the Government of India's critical mineral auction. This move supports India's resource security and self-reliance goals, strengthens fertiliser security, and reduces import dependence.

Zinnovation 2026: AI-Led Industrial Transformation

Hindustan Zinc, in collaboration with V-Spark DeepTech Ventures, hosted Zinnovation 2026, a strategic AI and deep-tech platform designed to accelerate transformation across mining, smelting, and manufacturing operations. The event brought together 40+ technology partners and startups, with keynote addresses by Chairman V-Spark Mr. Akash Hebbar and HZL CEO Mr. Arun Misra. Panel discussions featured senior leaders from Microsoft and Accenture, while fireside chats included representatives from Google, Accenture, and Infinite Uptime. Key MoUs were signed with technology partners to pilot innovations, with a stated value delivery vision of ₹2,000 Cr+. The event underscored the company's focus on scalable, pilot-ready AI solutions for smarter, safer, and more sustainable industrial operations.

Hindustan Zinc Limited has stated that it has no details regarding the reported government stake sale, calling media reports on the matter speculation. This comes after earlier reports suggested the Indian government was considering selling a 2% stake in the company, a transaction that could raise up to 50 billion rupees, or approximately $525 million.

Proposed Stake Sale Details

The key parameters of the reported government stake sale, as cited in earlier media reports, are outlined below:

Company's Response

Hindustan Zinc has distanced itself from the reports, clarifying that it has no information about any such government divestment plan. The company characterized the media coverage as speculation, indicating that no formal communication or details have been shared with it regarding the proposed transaction.

Background

The potential stake sale had been reported as part of the government's broader consideration of share sales in state-linked entities. Hindustan Zinc is one of India's prominent producers of zinc and lead, with the government holding a stake in the company alongside majority owner Vedanta. The proposed 2% offload, if executed, would have represented a significant liquidity event for the government.
