Hotmuck, ..lets get back over to the bulk sample area of 16 gr and take out a few rounds..A Sudbury miner would drill off a 10x12x8 = 960 cu ft ( 83 tn ) and keep the strip ratio down or if a wider vein warrants then cut a ten or 12 width. Alittle bit of high grade throwen in the mix could raise the oz"s pretty quick here....Traps7
