Vancouver – Through wholly owned subsidiary Redfern Resources, Redcorp Ventures (RDV-T) has launched an exploration program aimed at reviving the past-producing Tulsequah Chief massive sulphide project in northwestern British Columbia.
Redfern previously spent $36 million to advance the former zinc-copper-silver-gold mine project to the mine-development permitting stage. Legal challenges from environmental groups stalled development for several years, but the company has since received environmental certification from both federal and provincial agencies, along with a Special Use Permit governing use of an access road.
Redfern is preparing to select an engineering consultant to lead a new feasibility study scheduled for completion later this year. Based on previous studies, the polymetallic massive sulphide deposit hosts measured and indicated resources totaling 5.38 million tonnes grading 1.41% copper, 1.32% lead, 6.73% zinc, 2.73 grams gold and 100.8 grams silver per tonne. A further 1.54 million tonnes of 1.13% copper, 1.07% lead, 5.44% zinc, 2.23 grams gold and 85.1 grams silver are classified as an inferred resource.
The work program proposed for this year will include at least 20,000 metres of drilling, with six holes aimed at testing the upper levels of the Tulsequah deposit. Surface drilling will test various priority exploration targets, including 13,500 metres at the past-producing Big Bull mine deposit.
Big Bull is situated 9 km from Tulsequah Chief, on the same property. Previous production totaled 360,073 tonnes grading 1.2% copper, 1.9% lead, 7.3% zinc, 5.14 grams gold and 154.29 grams silver. Previous drilling (1993-1994) had identified extensions to known mineralization, but no resource estimates were completed at that time.
