Foreword It is known that the Chetwurn region was a Cu-Au vantage point from 1902. Previous surveys have focused on a small area two kilometers southwest of the newly discovered area at Selco, BP Resources Canada. In 1982, the company made its first profit in the area. In 1983 the implementation of a preliminary survey, after the mine hit the hole that year. After two years of rapid progress, it has been determined that the mine has 4.5 million g / t Au ore 11.2 million tons, the border grade 2.5g / t. A comprehensive estimate of gold 62.2 tons (two million ounces) border grade 1g / t. In 1985, about 31 kg of gold (1000 oz) was produced by the dumpling method. Underground mining is expected in mid-1986.
