This sounds promising. Assume the mining cost of the ROM ore to be $60/ton, sorting costs at $15/ton, and one needs two tons head grade to produce one ton of "super" grade – into a truck or railway car – than that could be shipped to an arsenopyrite processor,say in Red Lake, say for $100/ton.
Sorting and Loading: All expense of hand-concentration; the cost of tramming to the dump the waste picked from the ore, of loading the ore into the railroad-cars for shipment, and of keeping the ore-houses and bins in repair. Pumping: The cost of keeping the mine dry, including repairs to both pumps and lines.
