Last fall Suntac entered into an option agreement with Rembrandt Gold Mines (ASE) to earn a 60% interest in the former producer located in the Tulsequah River area of northwestern British Columbia. This year’s program is designed to continue testing areas outside the fully diluted reserve of 244,000 tons grading 0.33 oz gold per ton.
Hole 89-1 returned 8 ft of 1.17 oz gold. Hole 89-2 returned 18 ft of 0.548 oz and a 44.2-ft interval grading 0.536 which included 12.7 ft of 1.034 oz and 27.5 ft of 0.472 oz. The company plans to drill further holes to orient the significant intercepts encountered in hole 89-2.
Hole 89-3 intersected 4 ft of 0.498 oz, 1.8 ft of 0.419 oz and 11.8 ft of 0.412 oz grade gold.
Suntac’s objective this season is to outline sufficient tonnage to enable it to commission a feasibility study later this year or in early 1990. A mill no longer exists on the property, although the mill building remains. The property is air or barge-accessed.
Classified as a mesothermal lode gold deposit, the Polaris-Taku mine produced 230,000 oz of gold from ore grading 0.47 oz from 1938 to 1951. Gold mineralization is in quartz veins and associated altered volcanics, with the gold associated with arsenopyrite.
Previous operators produced flotation concentrates that were shipped by barge to a smelter, however, in the later years of production a roaster and cyanide plant were added to improve recoveries to about 93% and partly reduce shipping costs. Suntac intends to examine modern methods to enhance metallurgical recoveries.
