Murphys Law appears to have been repealed at the Table Mountain project near Cassiar, B.C. Cusac Industries (TSE) has found that the Michelle Highgrade zone is not under water as previously thought.
In addition to developing the Bain vein, Cusac is evaluating the old mining areas, which date back to Total Engergolds involvement in the operation. Total had attempted to reach the Michelle Highgrade zone from its existing Eileen vein workings but was forced to suspend the development about 650 ft. short of the target because of extreme water flows.
Drilling on the zone in 1987 returned some spectacular results, including 6 ft. grading 3.7 oz. gold per ton in Hole 87-205, 10 ft. grading 12 oz. in Hole 87-200, 5 ft. grading 0.84 oz. in Hole 87-230, and 7 ft. grading 1.3 oz. in Hole 87-236.
To circumvent the water problem, Total started a 7,000-ft.-long haulageway to the zone but the company stopped about 2,000 ft. short of the target because of financial constraints and a change in exploration plans.
Cusac reports that the haulageway provided drainage to the Eileen workings and that they are now completely dry.
It adds that its work on the Bain vein development is ahead of schedule. A decline to the zone is finished and 100 ft. of lateral development on the vein have been completed. The decline measures 700 ft. long, 9 ft. high and 12 ft. wide Cusac plans to process the Bain veins 36,000 tons of minable reserves in 1994, using the existing 300-ton-per-day mill.
Based on a grade of about 0.69 oz., production is expected to total 23,000 oz. at a cash operating cost of less than US$200 per oz.
