RE:Au and Ag samples in the latest NRCorrect me if I'm wrong but a quick google search says that on average you need a minimum of 5g of gold per ton of rock to be economically viable. None of the drill holes in the Starcore press release meets that threshold.
A similar search indicates that you need at least 200g of silver per ton to be economically viable and only three of the dril holes just barely meet that threshold.
The drill results from my (limited) undertanding seem to indicate they are not finding enough gold. The silver seems to be enough that it's a nice "bonus" if mined as a by-product of moly but forget about any primary silver mining.
