elizabeth. maybe not NI-43-101 agreeable) from 558 mil tonnes who has one.43 billion kilograms off copper, billion g off gold and 140 billion kilograms regarding molybdenum of the newest leached limit, supergene (oxide and you may sulphide) and you may hypogene zones. Included in this calculation try a widened high-grade open-pit mineable center regarding 90 million tonnes progressing 0.4% copper, 0.05% molybdenum and you can 0.forty-eight g/t silver. (Yukon Exploration and Geology 1993, p. 4 and you can Pacific Sentinel Silver Corp. 1993 Annual Report p. 4).

Which led to an overall reduced amount of the new tonnage reported to possess the fresh new measured and you can inferred categories when compared with beliefs reported for the the fresh new 2004 funding estimate.

The latest leached limit/oxide silver zone (with the an excellent 0.40 g/t gold cutoff) already hosts an extra thirty two million tonnes off shared counted and you can shown resources.
