elizabeth. not NI-43-101 agreeable) regarding 558 billion tonnes who has one.43 billion kilograms out of copper, million g from silver and 140 mil kilograms from molybdenum away from the fresh leached cover, supergene (oxide and you may sulphide) and you will hypogene areas. One of them computation was a widened high-grade open-pit mineable core regarding 90 million tonnes grading 0.4% copper, 0.05% molybdenum and you will 0.48 g/t silver. (Yukon Mining and you will Geology 1993, p. 4 and you will Pacific Sentinel Gold Corp. 1993 Yearly Report p. 4).
