Estimates For Mount Polley And Huckleberry Mines

VANCOUVER, BC - Imperial Metals Corporation has updated the mineral reserve and mineral resource estimates for the Mount Polley and Huckleberry mines.
Mount Polley Updated Mineral Reserve and Mineral Resource Estimate
The reserve and resource estimate for Mount Polley has been updated as of January 1, 2008. The current estimate incorporates open pit mining of the Southeast Zone, C2 Zone and the Springer Zone, in addition to the current Wight and Bell pits, and reflects twelve months of mine production since the January 1, 2007 estimate.
As of January 1, 2008 total Mount Polley reserves are 55.6 million tonnes of 0.36% copper, 0.30 g/t gold and 0.66 g/t silver, compared to 59.9 million tonnes of 0.36% copper, 0.27 g/t gold and 0.73 g/t silver at January 1, 2007. Exploration replaced 2.2 million tonnes of the 6.4 million tonnes mined in 2007. The current mine life for Mount Polley is to the fourth quarter of 2015. Drilling continues to expand the resources on the site, with 104 million tonnes of mineral resources identified in addition to the reserves.
ÊThe parameters used in this updated resource are based on updated pit designs and the current Mount Polley production schedule. The ultimate pit designs were based on US$1.80 copper, US$750.00 gold, US$10.00 silver and $1.176 CDN/US exchange rate.
On December 31, 2007 the mineral reserve of the Main Zone Extension pit was calculated at a cut-off grade of 0.200%. Probable reserves at December 31, 2007 were prepared under the supervision of Kent Christensen, P.Eng., Huckleberry Mine Chief Mine Engineer, designated as the Qualified Person for this purpose.
Prices used in the calculation of the Huckleberry reserves were US$1.63/lb copper, US$550.00/oz gold, US$8.50/oz silver, US$7.50/lb molybdenum and an exchange rate of $1.15 CDN/US.
