Hindustan zinc Limited announced exceptional production results for the fourth quarter and year ended March 31, 2026, achieving multiple records across key production metrics. The world's largest integrated zinc producer delivered its best-ever quarterly mined metal production and record refined metal output, demonstrating strong operational performance and capacity expansion benefits.

Record-Breaking Q4 FY26 Performance

The company achieved remarkable production milestones during Q4 FY26, setting new benchmarks across multiple categories:

The record quarterly mined metal production of 315 kt was driven by higher ore production and better grades across mining operations. Record quarterly refined metal production of 282 kt resulted from additional capacity unlocked through debottlenecking projects at Chanderiya and Dariba facilities, along with improved operational efficiency and higher plant availability.

Annual FY26 Production Achievements

For the full year FY26, Hindustan Zinc delivered outstanding results across all major production categories:

The company achieved its highest-ever mined metal production of 1,114 kt, representing a 2% increase from the previous year. This performance was supported by higher ore production and better grades across mining operations.

Operational Highlights and Capacity Expansion

Refined zinc production reached a best-ever annual output of 851 kt, up 3% year-over-year. This achievement was driven by the commissioning of debottlenecking projects and a 160 ktpa roaster, along with Pyro operations running on zinc-lead mode for the full year. The capacity expansion initiatives have successfully enhanced the company's production capabilities and operational efficiency.

Refined lead production decreased to 197 kt, down 13% year-over-year, primarily due to Pyro operations running partially on lead mode in the previous period and lower plant availability. Silver production of 627 tonnes aligned with lead production trends and reflected lower silver input from mines in accordance with the mining sequence.

Renewable Energy Performance

Wind power generation demonstrated strong performance with 372 MU produced during FY26, representing a 7% increase year-over-year. The quarterly wind power generation of 56 MU in Q4 FY26 was in line with prevailing wind velocity conditions, supporting the company's sustainable energy initiatives.

Production Strategy and Operational Excellence

The exceptional production results reflect Hindustan Zinc's successful execution of capacity expansion projects and operational optimization initiatives. The debottlenecking projects at key facilities have unlocked additional production capacity, while improved operational efficiency and higher plant availability have contributed to record-breaking performance across multiple metrics. The company's focus on mining sequence optimization and grade management has supported sustained production growth and operational excellence.

Hindustan Zinc has officially announced a strengthened partnership with Tata Steel to scale the integration of EcoZen, its low-carbon zinc solution, into sustainable steel manufacturing processes. The collaboration, formalized through a press release filed under Regulation 30, marks a significant evolution in the companies' two-decade strategic relationship.

Partnership Expansion Details

The enhanced collaboration builds on Hindustan Zinc's position as the world's largest integrated zinc producer and focuses on expanding EcoZen adoption across Tata Steel's operations. EcoZen, Asia's first low-carbon zinc, is produced using renewable energy and delivers substantial environmental benefits for steel manufacturing.

Environmental Impact and Benefits

EcoZen's verified carbon footprint of less than 1 tonne of CO₂ equivalent per tonne of zinc represents approximately 75% lower carbon intensity than conventional zinc production. The adoption of EcoZen can help avoid approximately 400 kg of CO₂ emissions per tonne of steel galvanised, compared to conventional zinc, providing customers with a tangible pathway to reducing Scope 3 emissions.

Leadership Perspectives

Mr. Arun Misra, CEO of Hindustan Zinc, emphasized that "EcoZen represents our vision to offer sustainable metal solutions that support the evolving needs of global manufacturing. Our partnership with Tata Steel is a significant milestone in scaling up the adoption of low-carbon zinc and reinforcing greener supply chains across India's industrial ecosystem."

Mr. Ranjan Sinha, Chief Procurement Officer at Tata Steel, congratulated the strategic partner on delivering EcoZen to their Sahibabad plant, highlighting their shared commitment to sustainable practices and advancing green technologies within their supplier ecosystem.

Strategic Industry Impact

The collaboration reinforces climate-aligned metal sourcing across steel and industrial applications, supporting broader sustainability commitments from Scope 3 emissions reduction to climate-aligned procurement frameworks. Zinc plays a vital role in galvanising steel for corrosion protection across sectors including infrastructure, automotive, renewable energy, electronics, and energy storage, making this low-carbon solution particularly significant for downstream industries seeking to advance their decarbonisation goals.
