Hindustan Zinc Limited (�HZL� or the �Company�) today announced its results for the first quarter ended 30 June 2008 (�Q1�). Revenues and net profit for Q1 were Rs 1,644 crore and Rs 848 crore respectively. Unaudited Financial Summary � � (in Rs crore, except as stated) � Q1 FY 2008-09 FY 2007-08 % Change Net Sales/Income from operations 1,644 1,970 - 17% Cash Profit (PBDT) 1,180 1,725 -32% Net Profit After Taxes 848 1,211 -30% Earnings Per Share (Rs.) 20.07 28.67 Production � Mined Metal (MT) Zinc 138,278 134,339 3% Lead 19,584 19,442 1% Production � Saleable Metal (MT) Zinc 127,889 92,631 38% Lead 17,298 13,651 27% During Q1, HZL produced 127,889 tonnes of zinc and 17,298 tonnes of lead, an increase of 38% and 27% respectively compared with the corresponding prior quarter. The mined zinc metal and lead metal production was marginally up at 138,278 tonnes and 17,298 tonnes respectively. During the quarter, the sale of zinc and lead concentrate was lower at 10,507 dry metric tonnes as compared to 54,385 dry metric tonnes in the corresponding prior quarter. This was primarily on account of higher smelter production, leading to a decrease in the surplus concentrate available for sale. The positive impact of higher volumes on sales and PBDT in Q1 was offset by the adverse impact on account of a decline in zinc LME prices (from US $3,667 in Q1 FY 2008 to US $2,115 in Q1 FY 2009) by 42%. During Q1, the Company was able to achieve significant reduction in the operating cost on the back of increased volumes, improved operational efficiencies and higher byproduct credits. Progress of Projects In Q1, the Company successfully commissioned 88,000 tpa zinc debottlenecking project at Chanderiya and Debari. With the commissioning of 16 MW wind power generation capacities, HZL has successfully completed its ongoing wind energy project and now has capacity of 123.2 MW wind power. During the quarter, HZL announced expansion projects that will take its total integrated zinc-lead capacity to 1,065,000 tonnes per annum with fully integrated mining, smelting and captive power generation capacities; making HZL the world�s largest integrated zinc-lead producer by 2010. The total investment in these projects is estimated at Rs. 3,600 crore.
