elizabeth. perhaps not NI-43-101 certified) away from 558 billion tonnes with 1.43 mil kilograms out of copper, billion g away from gold and you may 140 billion kilograms off molybdenum off the fresh new leached cover, supergene (oxide and sulphide) and you will hypogene zones. One of them calculation is actually a widened high quality open pit mineable core out of ninety mil tonnes grading 0.4% copper, 0.05% molybdenum and 0.forty-eight grams/t silver. (Yukon Mining and you will Geology 1993, p. 4 and you will Pacific Sentinel Gold Corp. 1993 Annual Declaration p. 4).
