I have been trying how to figure the silver amounts in this article. The silver is actually based on the "94.03 kilos of fine concentrates recovered from our processing of over 18,000 yards of frozen gold bearing gravels" Do we have any mining experts out there that can figure the tons of ore from 18,000 yards of ore??? What does a yard (cu/yd?) of ore weigh? That way the math would give an honest representation of how much silver is in the sample, converted to ounces/ton. Mind you I am in no way suggesting this is typical of the total Nolan properties, just this particular sample to show silver is present.
