Principal Raw Materials<br />
The principal inputs of HZL’s zinc smelting business are zinc and lead concentrates and power. HZL has in the past been able to secure an<br />
adequate supply of the principal inputs for its business.<br />
Zinc and Lead Concentrates<br />
Zinc and lead concentrates are the principal raw material of HZL’s smelters. HZL’s lead-zinc mines have provided all of its requirements<br />
for zinc and lead concentrates in the past. We expect HZL’s mines to continue to provide all of its zinc and lead concentrate requirements for<br />
the foreseeable future.<br />
Power<br />
Most of HZL’s operations are powered by the coal-based captive power plants at Chanderiya, for which HZL imports the necessary thermal<br />
coal from a number of third party suppliers. HZL has outsourced the day-to-day operation and maintenance of its captive power plants at<br />
Chanderiya, Debari and Zawar. In January 2006, HZL secured, as part of a consortium with five other partners, the award of a coal block from<br />
the Madanpur Coal Block which is expected to help meet the coal requirements of its captive power plants in the future. HZL’s share of the<br />
coal block is approximately 31.5 million tons which, according to the Ministry of Coal of the Government of <strong>India</strong>, are proven reserves with<br />
ash content ranging from 28.7% to 47.0% and with gross calorific value ranging from 3,865 Kcal/kg to 5,597 Kcal/kg. On June 16, 2008, the<br />
Ministry of Coal of the Government of <strong>India</strong> approved our mining plan. HZL has also been awarded 1.625 million tons of coal linkage by the<br />
Ministry of Coal of the Government of <strong>India</strong>, which will enable us to source coal from mines of SECL.<br />
