Imperial Update on Mount Polley Exploration

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Aug. 11, 2009) - Imperial Metals Corporation (TSX:III) reports exploration results from the Boundary, Pond, Springer, C2 and WX zones at its Mount Polley mine property. Drilling returned significant intervals of copper/gold mineralization at all of the zones.

The 2009 drill program has focused on the Boundary zone. Highlights include drill hole ND09-79 which intersected 157.0 metres grading 1.73% copper, 1.11 g/t gold and 10.53 g/t silver starting at 158.1 metres below surface. This area is being explored for underground mineable mineralization that is too deep to be captured in the current open pit design. High grade intercepts have also been encountered in holes ND09-80, ND09-82 and ND09-83.

The exploration strategy at Pond zone is to delineate high grade mineralization below the designed open pit, which may be amenable to underground mining. Drillhole PZ09-35 returned 71.3 metres grading 0.57% copper, 0.22 g/t gold and 6.81 g/t silver, but more notably included a 4.4 metre section of 4.20% copper, 1.03 g/t gold and 52.31 g/t silver. Drill hole PZ09-43 also proved fruitful with an intercept of 9.3 metres grading 6.40% copper, 0.89 g/t gold and 67.68 g/t silver. The 2009 drill program at Pond zone will explore the portion of skarn mineralization that carries the highest grades discovered to date.

In contrast to the exploration strategy at the Boundary and Pond zones, Springer zone drilling tested for long intercepts of copper/gold mineralization. Drill holes SD08-70, SD08-71 and SD08-72 all returned intercepts exceeding 350.0 metres in length, of which the best was SD08-72 returning 371.0 metres grading 0.51% copper and 0.26 g/t gold starting at 9.1 metres below surface. This drilling demonstrated that although mining has been initiated at Springer, expansion potential remains high. Additional drilling is planned.

Research of historic records has revealed the existence of a series of historic mineralization, short x-ray sized drill holes dating back to the 1960's which had returned some indication of copper mineralization, although no gold analysis was completed at that time. The drill holes were not accurately surveyed and field investigation could not conclusively locate the historic work. Two holes were drilled to test the area dubbed the "WX zone" thought to host this historic work. Both holes returned intervals of copper/gold mineralization. Drill hole WX09-02 returned 90.4 metres grading 0.36% copper and 0.96 g/t gold starting at 117.1 metres downhole, including a 5.0 metre section grading 0.66% copper and 2.96 g/t gold. Additional drilling is planned to follow up on this discovery.

Infill drilling at C2 zone was successful in confirming mineralization, particularly in drill hole C209-80 which returned 19.3 metres grading 1.85% copper and 2.15 g/t gold, including 6.7 metres grading 3.77% copper and 4.33 g/t gold. The high grades and favourable gold:copper ratio have recently raised the profile of C2 zone in regard to exploration. Additional holes to expand this high gold zone are currently being contemplated.

Drilling is expected to continue on these and other zones for the remainder of 2009, including the newly acquired extension of the Boundary zone (ref: NR April 28/09).

Steve Robertson, P.Geo. is the designated Qualified Person as defined by National Instrument 43-101 for the exploration programs. Samples for the diamond drilling reported at Mount Polley were analyzed at the Mount Polley mine laboratory and Acme Analytical Laboratories in Vancouver. As silver has become a more significant commodity in the Boundary and Pond zone exploration, some samples analyzed at Mount Polley are subsequently sent to Acme Lab for silver analysis. A full QA/QC program using blanks, standards and duplicates was maintained for all samples submitted to the labs. The porphyry and breccia related deposits at Mount Polley are irregular in shape and true thicknesses have not been estimated.
