e. not NI-43-101 certified) from 558 million tonnes who has 1.43 million kilograms regarding copper, million grams away from silver and you will 140 billion kilograms from molybdenum out of the fresh leached limit, supergene (oxide and you can sulphide) and hypogene areas. Included in this computation try an expanded high quality open pit mineable key away from 90 billion tonnes progressing 0.4% copper, 0.05% molybdenum and you may 0.forty eight grams/t gold. (Yukon Exploration and you may Geology 1993, p. four and Pacific Sentinel Gold Corp. 1993 Annual Declaration p. 4).
