The current ore production capacity today stands at 12 million tonnes per annum. The Company is aggressively expanding its mining capacities, implementing six ongoing major mining projects. Rampura Agucha Mine, with an ore production capacity of 6.15 million tonnes per annum, is the world’s 2nd largest Zinc-Lead mine with best-in-class Zinc-Lead reserves grade. The mine is currently operating through open-cast and underground routes. The Sindesar Khurd Mine, with an ore production capacity of 4.5 million tonnes per annum, is a highly mechanized underground mine. As part of the on-going expansions, the ore production capacity is set to increase to 6 million tonnes per annum in the coming years. Sindesar Khurd Mine expansion is expected to significantly contribute to the Company’s integrated Silver production. Zawar Mines comprises 4 different mines with footprints of ancient mining and has a combined ore production capacity of 4 million tonnes per annum. As per the radiocarbon dating, the mines at Zawar are over 2500 years old. The Company is on-course to expand Zawar Mines capacities to over 8.0 million tonnes in the next five years through mechanization and by switching-over to trackless mining. Zawar also has 80 MW of captive thermal power plants.

Rajpura Dariba Mine is an underground mine and currently has ore production capacity of 0.9 million tonne per annum. The ore production capacity at Rajpura Dariba Mine is all set to increase to 1.2 million tonne per annum.
