QUEBEC – CAMPBELL RESOURCES (50%) of Montreal and NUINSCO RESOURCES (50%) of Toronto have the flooding problem under control at their Corner Bay copper project near Chibougamau. Campbell reported in mid-December 2007 that excessive inflows of water were encountered as development neared the ore zone.

Pumping capacity has been increased to reduce the volume and pressure of the water in the host rocks around the orebody, and the remaining leaks have been grouted.

Development in ore will begin soon, says Campbell, on both the 55-metre and 75-metre levels. Lengthening the main ramp will also resume. To date 465 metres of the main ramp have been completed to a vertical depth of 85 metres. Ore from the Corner Bay mine will be trucked 45 km and processed at Campbell’s Copper Rand mill.

Corner Bay remains open at depth, where drilling has returned intercepts grading up to 9.27% Cu over 6.7 metres at 1,200 vertical metres. An exploration drilling program is planned for 2008 to further test the extension at depth. At a 3% Cu cut-off, Corner Bay has measured and indicated resources of 446,000 tonnes averaging 5.58% Cu and inferred resources totalling 1,441,000 tonnes averaging 6.76% Cu.
