The Hindustan Zinc’s journey of excellence continued to translate into many landmark achievements across our mines during FY 2022-23. The focus remained on boosting innovation, technology, safety, productivity and efficiency. Aligning ourselves more intricately with our Sustainability Goals 2025, we pushed the bar higher to make our operations more sustainable as we advanced further towards carbon neutrality.

Our operational metrics for the year underline the success of our initiatives and innovations. During the year, we posted a record high refined metal production, which crossed the 1 million tonne mark on the back of consistent mined metal production. Our mined metal production also grew by 4% over the previous fiscal to touch the highest ever at 1,062 kt in FY 2022-23, driven by higher ore production, improved mined metal grades and operational efficiencies.

Our diligent and innovative approach yielded outstanding operational results this year, despite facing multiple obstacles. By learning from our knock-backs, we emerged stronger than before and achieved significant success in areas like subsequently more than 1 million tonnes MIC delivery, above 91% stope recovery, and significant reduction in total ore dilution. Looking ahead, our devotion to implementing new innovations and achieving operational excellence through digitalisation will propel us to even greater heights. Through prioritising safety, innovation, quality, automation, and optimal metrics, we will continue to exceed expectations, opening up new opportunities for expansion and growth.

Our prime focus will always remain on sustainable practices in line with the Group’s ESG vision. With driving zero liquid discharge projects across locations, introduction of electric vehicles and continuous operations of paste fill, hydraulic fill and dry tailings plant, we are committed to delivering sustainable and responsible growth. With such a historic and outstanding metal production of 1 Mtpa by Hindustan Zinc during FY 2022-23, we are striving towards 1.1 Mtpa of finished goods in FY 2023-24. This shows our unwavering commitment towards our focus on quality and safety practices surpassing industry benchmarks. With such a huge leap in delivering the targets, we are embracing innovation and leveraging cutting-edge technologies to revolutionised operations, improving productivity and optimising efficiency. Aligning with the global mining standards, we are incorporating the robust design practices in mine planning and minimising the cost through ‘technical cost reduction programme’ for achieving the long-term vision of the Company. With a pool of very young and energetic world-class talents with visionary mindset, we are quite optimistic in achieving new heights of excellence.

Having scaled many milestones in FY 2022-23, we are now looking at enhancing the reserves base of the mine with deeper areas of exploration. We are also taking multiple actions for improving safety and keeping risks under control through critical risk management techniques. With the mine going deeper, there will be enhanced focus on improving the enabling infrastructure services and geo-tech management. Equipment and asset health, along with their fullest utilisation, will be the key mantra to drive future growth. RAM is being developed as a model asset optimisation location through our new initiative ‘Utthaan’. This initiative will propel the mine towards total productive maintenance, by upskilling operators and creating a sense of ownership for ensuring machine health and improved productivity. We are also building best-in-class maintenance infrastructure and systems. Digital transformation is another area of focus, and we are working towards tele-remote operation of equipment. There will also be enhanced focus on improving the diversity and inclusivity of the workforce at all levels.
