The VP of shore gold has stated that they would require a MINIMUM of $15/tonne rock, so even using the results from the 235m level 17 CPHT, plus $10-$12 mining/processing costs it would TAKE a min $160 US/carat valuation to have feasibility.
I am still being generous with the 17 CPHT since Shore is on pace for about 13 CPHT which would require a higher valuation.
