elizabeth. not NI-43-101 certified) away from 558 billion tonnes who has 1.43 mil kilograms regarding copper, billion g regarding gold and you will 140 million kilograms from molybdenum away from the fresh new leached cover, supergene ( Clemens Spillehal SE oxide and sulphide) and you will hypogene zones. One of them formula is actually an extended high-grade open pit mineable key regarding ninety mil tonnes grading 0.4% copper, 0.05% molybdenum and 0.48 grams/t gold. (Yukon Exploration and Geology 1993, p. 4 and you will Pacific Sentinel Silver Corp. 1993 Annual Statement p. 4).
