BRITISH COLUMBIA – Imperial Metals Corp. of Vancouver says the Boundary zone at the Mount Polley copper-gold mine continues to demonstrate discovery potential. Underground drilling from three drill station on the 812 level intersected breccia hosted copper-gold mineralization confirming continuity and extending the know limits of the nearby but separate Zuke zone.
The Zuke zone is currently modelled as two steeply dipping breccia lenses, approximately 8 metres wide, 30 metres high and 75 metres long. The two lenses are separated by a 5-metre-wide unmineralized core and are also cut by a post mineral dyke having a strike of 55° and dips 48° to the southeast. Imperial also noted that the breccias at Mount Polley are normally irregular bodies with no specific orientation, but the Zuke zone breccias have a planar geometry so true thicknesses have been estimated for drill holes that cross the zone.
Drill hole NDU12-196 returned 12.8 metres (estimated true width 8.0 metres) grading 4.73% Cu, 2.61 g/t Au and 30.05 g/t Ag starting at 22.1 metres, and drill hole NDU12-197 intersected a higher grade interval of 9.66% Cu, 6.42 g/t Au and 52.81 g/t Ag over 2.8 metres.
Last year the company completed approximately 986 metres of ramping and drifting in the Boundary zone including the decline which was extended down to the 782 metre level. This work will allow for test mining of a selected block of the high grade Boundary zone breccia mineralization approximately 60 metres long and 18 metres wide, extending from the 752 to the 842 metre levels.
