e. maybe not NI-43-101 agreeable) of 558 million tonnes with one.43 million kilograms off copper, mil g out of silver and you can 140 million kilograms of molybdenum regarding the new leached cap, supergene (oxide and you can sulphide) and hypogene zones. Included in this computation try a broadened high quality open pit mineable key regarding 90 billion tonnes grading 0.4% copper, 0.05% molybdenum and you will 0.forty-eight grams/t silver. (Yukon Exploration and Geology 1993, p. four and you may Pacific Sentinel Gold Corp. 1993 Yearly Declaration p. 4).

This triggered an overall total reduced total of the fresh tonnage said to own the latest measured and you can inferred classes in comparison to values said for the the new 2004 financing guess.
The fresh new 2008 pre-feasibility research as well as provided the first NI 43-101 mineral put aside imagine towards Casino project.
