elizabeth. perhaps not NI-43-101 compliant) off 558 billion tonnes which has one.43 mil kilograms from copper, billion grams out of gold and 140 mil kilograms of molybdenum away from the fresh leached limit, supergene (oxide and you may sulphide) and hypogene areas. One of them computation try a broadened high grade open-pit mineable center off 90 mil tonnes grading 0.4% copper, 0.05% molybdenum and 0.forty eight grams/t silver. (Yukon Mining and you can Geology 1993, p. 4 and you will Pacific Sentinel Gold Corp. 1993 Annual Report p. 4).

The fresh new leached limit/oxide gold region (with their a great 0.forty g/t gold cutoff) already hosts an additional thirty-two million tonnes out of combined counted and expressed resources.
