LP Fault will likely be mined by block cave method
LP Fault will likely be mined by block cave methodeventually, which means a 1 g/t gold grade cutoff could be feasible based on current gold prices. Therefore we can include any contained ounces above that 1 g/t cut-off in our estimates of resource potential.
cut-off grades of open pit and block cave mining methods are not dramatically different, because the mining costs associated with them are not dramatically different
