Vancouver – Initial drill results from Bell Resources’ (BL-V, BZRSF-O) Granduc mine project, in northwestern British Columbia, delivered significant copper grades.
The 5-hole program testing geophysical targets at the past producer cut zones of chalcopyrite-magnetite-pyrrhotite mineralization returning high-grade copper values. Results include:
- Hole 2005-1 intersected 7.6 metres of true thickness (from 92.7-metres downhole depth) averaging 2.2% copper and 11.8 grams silver per tonne, and two 2-metre intercepts deeper downhole grading 1.7% and 1.8% copper and 18.8 and 21.8 grams silver respectively;
- Hole 2005-3 cut a true width of 4 metres (from 163 metres) grading 1.8% copper and 20.7 grams silver, followed by a deeper 4.8 metre interval of 1.5% copper and 13.1 grams silver;
- Hole 2005-4 returned a true width section of 7.8 metres (from 218- metres depth) averaged 2.6% copper and 6.7 grams silver, with a deeper 3.4-metres (from 366 metres) of 2% copper and 20.3 grams silver; and
- Hole 2005-5 intersected three zones of mineralization, 1.7 metres (from 197 metres) of 2.4% copper and 17.4 grams silver, 1.5 metres (from 263 metres) of 3.9% copper and 36 grams silver, and 8.1 metres (from 417 metres) grading 2.1% copper and 23.2 grams silver.
Copper-gold mineralized intercepts also ran from 0.1-0.25 gram gold per tonne with some minor cobalt values. Holes were positioned south of historic mining workings to test the strike continuity of known ore horizons, confirming the sulphide-ore zones previously mined at Granduc extend at least 240 metres southward along strike and more than 240 metres downdip. Results indicate a trend of increasing copper grade and thickness both downdip and to the southwest. Mineralization is open in both directions.
Historic grades from the Granduc mine averaged 1.8% copper, 7 grams silver and 0.1 gram gold.
The mine operated from 1969 to 1983, producing about 420-million pounds of copper, 4 million oz. of silver and some gold from the volcanogenic massive sulphide deposit.
