Imperial Metals has announced underground drilling results from the high-grade Boundary zone of Mount Polley and surface drilling results from the WX zone.
The company has conducted underground drilling at the Boundary and cut numerous high-grade breccias including 2.56% copper, 1.68 g/t gold and 14.59 g/t silver over 27.5 metres in hole NDU11-160. Also, the hole NDU11-149 has returned 4.23% copper, 1.51 g/t gold and 35.26 g/t silver over 9.5 metres.
The company focuses exploration on the Boundary zone at the Mount Polley property and the Cariboo, WX and C2 zones near the Springer pit.
The initial 17 underground hole results from the Boundary zone have confirmed the high-grade mineralization continuity hosted in a brecciated monzonite. The recent underground program has been planned to add to the formerly reported surface drilling and offer thorough information about the Boundary zone breccia. The stope mining analysis at the Boundary zone offers geotechnical and cost data needed to expand an underground mining at Mount Polley.
Underground exploration holes are in progress to analyze the mineralization extent in the formerly exposed Zuke zone, besides describing the Boundary zone breccia. Surface drilling is continuing in both the north and south parts of the WX zone.
The hole WX11-46 has cut 0.26% copper and 0.26 g/t gold over 230 metres at the north side of the WX zone including 0.36% copper and 0.74 g/t gold over 41.7 metres. Imperial is drilling the targeted area to outline the mineralization at WX and C2 zones and below the Cariboo Pit.
