Sampling of an exploration drift directed to zone B on the 350-ft. level of the Wrightbar gold mine workings near Val d’Or, Que., has returned encouraging values, Lithos (ME) reports.
The old mine, closed since July, 1988, has been dewatered to the 550-ft. level. The project is now known as Bourlamaque-Nord.
The old drift was driven 400 ft., of which 200 ft. run alongside a quartz vein with a thickness of 2 to 6 ft.
Assays from the vein, sampled at 10-ft. intervals along the first 130 ft., returned 1.026 oz. gold per ton over an average width of 3.82 ft. (or, diluted, 0.787 oz. over an average 5-ft. width). The company awaits assays from the next 100 ft.
A report in February, 1988, listed estimated mine reserves of 305,000 tons grading 0.227 oz. (with 25% dilution) but made no reference to zone B. A work report in June, 1988, confirmed the extraction of 400 tons averaging 0.37 oz. from zone B.
Hoping to bring Bourlamaque-Nord into production, Lithos plans to extract a 10,000-ton bulk sample for testing.
Meanwhile, a unit of Noranda (TSE) continues to explore the southern portion of the old Wrightbar property for base metals under a 5-year agreement with Lithos. The project is known as Bourlamaque-Sud.
