A drill program is under way on the McNeil property held equally by Greenstone Resources (TSE) and Dragoon Resources (VSE). Located in the Kootenay area of the province, the McNeil property has geological similarities to the Sullivan base metals mine located 28 miles to the northwest.
The program will focus on testing a series of shear zones which range up to 16 ft in width and strike for more than 1,000 ft. Surface showings associated with the shears have assayed up to 55% lead, 12.4 oz of silver and 0.124 oz gold per ton, Greenstone says.
“This is a stratigraphic situation,” Ian Park, president of Greenstone explained to The Northern Miner. “We’ve had good lead, zinc and silver values in trenching.” Greenstone and Dragoon geologists believe the surface showings represent remobilized Sullivan-type mineralization which is associated with thrust faults. This, Park says, suggests that a Sullivan-type massive sulphide deposit could occur at a depth of 250 m and greater.
Sullivan-type lead-zinc deposits make a worthy target. Since beginning operations 79 years ago, the Sullivan mine has produced more than 180 million tons of ore.
The partners are also encouraged by a 7,500-ft long lead-zinc geochemical anomaly which could represent a `pooled’ sulphide deposit, similar to those known to occur beneath gabbro sills at the Sullivan mine.
The McNeil project is a part of Greenstone’s bid to further diversify into base metals. The company is better known for its gold projects in Latin America. Several of these in Colombia and Costa Rica are scheduled to enter production shortly.
