e. not NI-43-101 certified) regarding 558 million tonnes that has 1.43 mil kilograms from copper, billion grams off gold and you can 140 million kilograms from molybdenum out of the newest leached limit, supergene (oxide and you may sulphide) and hypogene areas. Included in this computation is a widened high-grade open-pit mineable key of 90 billion tonnes grading 0.4% copper, 0.05% molybdenum and you will 0.48 g/t silver. (Yukon Exploration and you may Geology 1993, p. 4 and you may Pacific Sentinel Silver Corp. 1993 Annual Report p. 4).

The brand new 2008 pre-feasibility data as well as integrated the initial NI 43-101 mineral set aside imagine into the Casino endeavor. The fresh set-aside guess will be based upon pit structure and mine manufacturing agenda developed in the fresh pre-feasibility investigation and is said while the a factory ore put aside and bunch leach set aside. The fresh heap leach set aside tonnage figure is large plus the gold grade is leaner than one reported on the resource guess.

The fresh leached limit/oxide silver area (making use of their good 0.forty g/t silver cutoff) already hosts a supplementary 32 million tonnes off combined measured and you may expressed info.
