e. maybe not NI-43-101 agreeable) of 558 million tonnes who has 1.43 mil kilograms regarding copper, million grams out of silver and you will 140 billion kilograms off molybdenum away from the newest leached limit, supergene (oxide and sulphide) and you will hypogene zones. Among them computation is actually a broadened high quality open-pit mineable center regarding 90 million tonnes leveling 0.4% copper, 0.05% molybdenum and you may 0.48 g/t silver. (Yukon Mining and you will Geology 1993, p. 4 and you will Pacific Sentinel Gold Corp. 1993 Yearly Declaration p. 4).

So it lead to an overall reduced total of the brand new tonnage advertised getting the fresh new mentioned and you may inferred classes when comparing to beliefs claimed in the the latest 2004 resource estimate.
The latest 2008 pre-feasibility analysis together with integrated the initial NI 43-101 nutrient set aside estimate towards Casino venture.

The fresh new leached limit/oxide silver zone (with the a good 0.forty grams/t silver cutoff) currently computers a supplementary 32 billion tonnes of shared counted and you may expressed resources.
