e. not NI-43-101 agreeable) away from 558 million tonnes containing one.43 billion kilograms off copper, billion g away from silver and you may 140 billion kilograms away from FairPari molybdenum of the latest leached limit, supergene (oxide and you will sulphide) and you may hypogene areas. One of them computation is an expanded high grade open pit mineable center off ninety mil tonnes progressing 0.4% copper, 0.05% molybdenum and you can 0.forty eight g/t gold. (Yukon Mining and Geology 1993, p. four and you will Pacific Sentinel Silver Corp. 1993 Annual Declaration p. 4).

The latest leached limit/oxide silver zone (using their an effective 0.forty grams/t silver cutoff) currently hosts an extra 32 million tonnes regarding shared counted and you will shown information.
