elizabeth. not NI-43-101 certified) regarding 558 million tonnes which has 1.43 million kilograms out of copper, mil grams of gold and 140 million kilograms out of molybdenum regarding the newest leached cap, supergene (oxide and you can sulphide) and you Wintopia casino may hypogene areas. Among them calculation is an extended high-grade open pit mineable center out of 90 million tonnes progressing 0.4% copper, 0.05% molybdenum and 0.forty-eight grams/t gold. (Yukon Exploration and you may Geology 1993, p. 4 and Pacific Sentinel Silver Corp. 1993 Annual Declaration p. 4).

The latest leached limit/oxide gold area (with regards to good 0.forty g/t silver cutoff) already servers an additional thirty-two billion tonnes of shared measured and you may conveyed resources.
