Lead-Zinc Mines<br />

HZL sources all of the lead-zinc ore required for its business from its Rampura Agucha open-pit mine and the Zawar and Rajpura Dariba<br />

(including Sindesar Khurd) underground mines in Northwest <strong>India</strong>. Lead-zinc ore extracted from the mines is conveyed to on-site concentrators<br />

and beneficiation plants that process the ore into zinc and lead concentrates. With its low strip ratio and good ore mineralogy providing a high<br />

metal recovery ratio, the Rampura Agucha mine accounted for 91% of HZL’s total mined metal in zinc concentrate produced in fiscal 2009,<br />

with the Zawar and Rajpura Dariba mines accounting for the remaining 4% and 5%, respectively. The zinc and lead concentrates are then<br />

transported by road to the nearby Chanderiya and Debari smelters and by rail and road to the Vizag smelter in Southeast <strong>India</strong>. HZL has also<br />

sold surplus zinc and lead concentrates from its mines to third party smelters.<br />
