e. maybe not NI-43-101 certified) away from 558 mil tonnes that has one.43 mil kilograms regarding copper, million g out of gold and you can 140 billion kilograms out of molybdenum of the new leached limit, supergene (oxide and sulphide) and hypogene areas. Included in this computation try a widened high quality open-pit mineable center off 90 mil tonnes progressing 0.4% copper, 0.05% molybdenum and you will 0.48 grams/t silver. (Yukon Exploration and you may Geology 1993, p. four and you may Pacific Sentinel Gold Corp. 1993 Yearly Report p. 4).
On the spring season away from 1994 Pacific Sentinel released a historical capital imagine (i

The fresh 2008 pre-feasibility investigation and included the original NI 43-101 nutrient put aside estimate towards Casino opportunity. The fresh set-aside imagine is dependant on gap structure and exploit manufacturing schedule developed in the new pre-feasibility investigation and that is claimed because a mill ore reserve and you will bunch leach reserve.

The fresh leached cap/oxide silver area (with regards to a great 0.forty grams/t silver cutoff) already computers an additional thirty-two billion tonnes of joint counted and you can expressed information.
