Hindustan Zinc's Rampura Agucha Becomes India's First Zinc Mark Mine

Hindustan Zinc Limited's Rampura Agucha Mine has become India's first mine to receive Zinc Mark certification, a globally recognised responsible production standard. The certification strengthens Hindustan Zinc's position in ESG-focused and traceable supply chain markets.

Hindustan Zinc Limited (BSE: 500188, NSE: HINDZINC), the world's largest integrated zinc producer, announced on May 25, 2026 that its Rampura Agucha Mine in Rajasthan has achieved Zinc Mark certification. Rampura Agucha is the world's largest underground zinc-lead mine and is a cornerstone asset in Hindustan Zinc's production base. Zinc Mark is a globally recognised assurance framework that validates responsible zinc production against internationally benchmarked Environmental, Social, and Governance standards.

The Zinc Mark framework assesses mines against criteria covering responsible sourcing, environmental stewardship, community engagement, and governance practices. Achieving certification at Rampura Agucha, India's first Zinc Mark certified mine, positions Hindustan Zinc to access ESG-sensitive customer segments and supply chains that increasingly require traceable, responsibly produced metals. This is particularly relevant as global manufacturers in automotive, electronics, and construction sectors face growing stakeholder and regulatory pressure to verify the ESG credentials of raw material suppliers.

The certification aligns with Hindustan Zinc's stated strategy of integrating sustainability, operational excellence, and responsible production into its core business model. For investors applying ESG screens, the Zinc Mark certification provides third-party validation of environmental and social performance at the mine site level, going beyond self-reported metrics. It also positions Hindustan Zinc competitively in export markets where the EU's Critical Raw Materials Act and supply chain due diligence regulations are driving demand for certified, traceable metals.
