AMOS, Que. The shaft at the Sleeping Giant gold mine is being deepened 200 m to reach a depth of 1,060 m. Owners CAMBIOR and AURIZON MINES are investing about $7 million in the project, which includes shaft sinking and lateral development of diamond drilling bases. The work is to be complete in the fourth quarter of 2004.
Underground diamond drilling is planned to verify the potential extensions of currently known mineralized zones or other mineralized zones below level 785. Deep drilling in 2001 discovered several new mineralized zones, notably zone 8. Drilling that year also identified significant mineral resources between levels 785 and 975.
The deepened shaft will permit the recovery of 77,000 tonnes of probable reserves grading 12.2 g/t Au and 192,000 tonnes of inferred resources grading 10.3 g/t Au. Mining these reserves and resources will extend the mine's life for another two years. During the deepening, ore production from the mine will continue at its scheduled rate of about 850 tonnes/day.
