Kayad

Overview

Kayad Mine is the latest addition to Hindustan Zinc’s mining portfolio, having commenced operations in 2011 and begun ore production in FY 2012–13.

Renowned for its systematic and scientific approach to underground mining, Kayad Mine initially reported Reserves and Resources of 7.7 million tonnes in FY 2013–14. Over time, the discovery of new ore lenses has significantly expanded its potential. As of FY 2025, the mine has produced a total of 9.9 million tonnes of ore and still holds an estimated 8.1 million tonnes in Reserve and Resources.

The extracted ore is transported for beneficiation to Rampura Agucha Mill in Bhilwara. Vertically integrated operations are fortified by continuous surface and underground exploration. In FY 2024-25, Kayad Mine (KM) accomplished a production of 0.7MT tonnes of ore, yielding 35,202 tonnes of metal concentrate. With 6.0 kilometres of development in existing and upcoming blocks, it is expected to sustain a production rate of 1.2 Mtpa in the years ahead.

In terms of digitalization and automation, Kayad Mine spearheaded transformative initiatives during FY 2022-23, including biometric-based driver authentication and an unmanned weightage system
