Metal/Mining: Hindustan Zinc to become world's largest integrated zinc-lead producer

Hindustan Zinc to Become World's Largest Integrated Zinc-Lead Producer Expanding capacity to 1,065,000 tpa, making HZL the largest integrated zinc-lead producer in the world and achieving stated capacity goal of 1?million tonnes per annum Silver production expected to increase to 500?tonnes per year Strong reserves and resources position of 232.3 million tonnes
containing a total of 27.5 million tonnes of zinc-lead metal

Mumbai, India - Hindustan Zinc Limited ("HZL") has announced expansion projects that will take its total integrated zinc-lead capacity to 1,065,000 tonnes per annum with fully integrated mining and captive power generation capacities, thereby making HZL the world's largest integrated zinc-lead producer by 2010.

HZL will continue to maintain its superior cost leadership position among the zinc producers in the world.

Two brownfield smelter projects, which will increase the production capacities of zinc and lead by 210,000 tonnes and 100,000 tonnes respectively, will be undertaken at Rajpura Dariba in Rajasthan, India.

HZL expects to increase its silver production from the current levels of approximately 100-120 tonnes per year to a level of approximately 500 tonnes per year in the form of silver and silver bearing residue.

A large part of this increase would be from the Sindesar Khurd mine where silver occurrences are approximately at levels of 200 ppm and from the use of appropriate technology in the new smelters.

The expansion is supported by HZL's strong reserves and resources of 232.3 million tonnes containing 27.5 million tonnes of zinc-lead metal at 31 March 2008. The reserves and resources position have been earlier independently reviewed and certified as per the JORC standard.

To support the increased smelting capacities, HZL will expand its ore production capacity at the Rampura Agucha mine from 5?mtpa to 6 mtpa.

Further, ore production at the Sindesar Khurd mine, the new star in HZL's mining portfolio, will be increased from 0.3 mtpa to 1.5 mtpa. HZL will also start mining activity at the Kayar mine which will have a production capacity of 0.3 mtpa.

In line with the group's philosophy of being a fully self-reliant producer of power, a captive thermal power plant with a capacity of 160MW will also be set up at Rajpura Dariba.

The zinc and lead smelters as well as the 160MW captive power plant and the Rampura Agucha mine expansion will be complete by mid-2010. The expansions at the Sindesar Khurd and Kayar mines will be completed in phases by early 2012.

The total investment in these projects is estimated at Rs. 3,600 crore.

This investment includes the cost of the smelters, captive power facilities, mine development and shaft sinking and other infrastructure.

The expansion will utilise the same technology and project management skills that successfully delivered the Chanderiya II expansion project ahead of schedule.

Metal/Mining/Business: Hindustan Zinc announces exploration success

Increase in reserves and resources by 28.7 million ronnes containing 4.0 million tonnes of zinc-lead metal, prior to depletion increase in mine life by nearly four years
Total reserves and resources now at 232.3 million tonnes containing 27.5 million tonnes of zinc-lead metal Rampura Agucha Mine achieves Landmark of crossing 100 million tonnes with certified reserves and resources of 107.3 million tonnes

Mumbai, India (BUSINESS WIRE) - Hindustan Zinc Limited ("HZL") is pleased to announce that its ongoing exploration activities have yielded significant success with an increase of 28.7 million tonnes to its reserves and resources, prior to a depletion of 5.8 million tonnes in FY 2008. Contained zinc-lead metal has increased by 4.0 million tonnes, prior to a depletion of 0.6 million tonnes during the same period. Total reserves and resources at 31 March 2008 were 232.3 million tonnes containing 27.5 million tonnes of zinc-lead metal. The reserves and resources position has been independently reviewed and certified as per JORC standard.

The success of exploration has primarily been in the Sindesar Khurd and Rampura Agucha mines. The sustained exploration and aggressive drilling programme at Sindesar Khurd mine has successfully augmented the resource base to the current level of 37 million tonnes, making it the second largest ore body in HZL's portfolio after Rampura Agucha, with potential for further additions, through ongoing exploration. In FY 2008, the drilling programme successfully increased the strike length, by 300 metres, to 1,600 metres averaging 5.8% zinc, 3.8% lead and 215 ppm silver.

At Rampura Agucha, 28,000 metres of drilling in 32 holes were carried out to outline mineralisation below a depth of 550 metres. Of these, 29 holes intersected ore widths with significant grades averaging 15.5% zinc and 2.0% lead. The combined reserves and resources at Rampura Agucha alone have been augmented to 107.3 million tonnes at 31 March 2008, achieving the landmark of crossing 100 million tonnes in reserves and resources.

The group's exploration philosophy has been to replace every tonne of ore mined with at least one tonne of resource.

HZL has dynamically increased its exploration focus, through a team of 40 geologists employing the latest geophysical, geochemical and GIS technologies and high speed deep drilling equipment. This has resulted in an addition of 110.7 million tonnes of reserves and resources, before depletion of 22.1 million tonnes, in the period from April 2003 to March 2008.
