Drilling by partners
Two of the four most recent holes tested the edges of the deposit’s Upper Duck lens. Drilling in the 1980s produced an inferred resource of 3.9 million tonnes grading 3.3% copper and 6.7% zinc, 1.1% lead, as well as 71 grams silver and 1.1 grams gold per tonne. Both new core holes intersected substantial lengths of massive-sulphide mineralization, suggesting that the strike of the deposit could extend southeast and northwest.
Sunk on the eastern margin of the deposit, hole 203 encountered 5.6 metres grading 2.4% copper, 6.3% zinc, 1.4% lead, 54 grams silver and 0.8 gram gold. The hole was collared 50 metres northeast of one of the partners’ first holes.
In hole 205, a 30.7-metre interval graded 4% copper, 9.6% zinc, 1.5% lead, 99 grams silver and 0.9 gram gold. That hole was collared near the northern end of the lens to test an area on the deposit’s northwestern fringe.
The two remaining holes, both infill, were drilled between holes that returned mineralization in the 1980s.
Hole 204, sunk about 50 metres northeast of hole 205, cut two zones of mineralization. The first was 7.1-metres long and graded 5.5% copper, 1.6% zinc, 0.1% lead, 24 grams silver and 0.2 gram gold. The second, sunk 14 metres deeper, was 27.9-metres long and graded 4.1% copper, 5.1% zinc, 1.1% lead, 77 grams silver and 1.2 grams gold.
Another hole, 206, encountered 14.8 metres of massive sulphides grading 2.8% copper, 5.5% zinc, 1.2% lead, 68 grams silver and 0.6 gram gold in the southern part of the deposit. It confirms the inferred thickness of the Upper Lens in that area.
