One of them formula try an expanded high quality open-pit mineable core off ninety million tonnes grading 0.4% copper, 0.05% molybdenum and 0.forty eight g/t silver. (Yukon Exploration and you will Geology 1993, p. 4 and you will Pacific Sentinel Silver Corp. 1993 Yearly Report p. 4).

Most other distinguished increases were acquired on the inferred capital of the supergene oxide, supergene sulphide and you will hypogene areas hence enhanced of 232 million tonnes to one 696 billion tonnes. 25% copper similar (Cu EQ) cutoff, complete one.06 billion tonnes of joint supergene oxide, supergene sulphide and you will hypogene mineralization in the measured and you can indicated level. The brand new leached limit/oxide silver region (employing a good 0.forty g/t silver cutoff) currently computers an extra thirty-two billion tonnes regarding joint mentioned and you will conveyed resources.
