One method for developing a mine will result in a recovery of 62% of the available ore deposit and will cost 1,150.00 per ton of material removed. A second method of development will recover 50% of the ore deposit, but it will cost only 4750.00 per ton of material removed. Subsequent processing of the removed ore recovers 300 pounds of metal from each ton of processed ore and costs P2,000 per ton of ore processed.
