Hole 90-29 on the Tulsequah Chief property was drilled into footwall andesite and stopped at a depth of 2,635 ft. without encountering H Lens mineralization. The Tulsequah property is in northwestern British Columbia where owners Cominco (TSE) and Redfern Resources (TSE) have been drilling deep holes to determine the downdip extent of the H Lens, a thick massive sulphide lens intersected in previous drilling.
Cominco, operator and 60% owner, encountered technical problems in drilling hole 90-29 when a clay-rich fault zone was encountered. Unable to penetrate the zone, the hole was wedged above the zone and continued to depth. The hole was targeted to intersect the H Lens about 400 ft. downdip from hole 90-23.
Hole 90-23, drilled earlier this year, intersected the H Lens over a length of 89.5 ft. grading 1.2% copper, 1.2% lead, 5.4% zinc, 0.11 oz. gold, and 4.2 oz. silver per ton.
Redfern said hole 90-29 had deviated considerably to the east and is believed to have missed the eastern boundary of the lens which dips to the north.
The market showed its disappointment in the drilling, pushing Redfern’s price to a low of $2.50 from the previous day’s close of $3.60.
Cominco plans to continue drilling hole 90-28 in January after a Christmas break. The hole encountered technical problems similar to hole 90-29.
Hole 90-28 is targeted at the centre of the H Lens downdip from hole 90-23 and should be completed by the end of January.
