Leroy Mining Company purchased land containing an estimated 10,000,000 tons of ore for a cost of $750,000. The land without the ore is estimated to be worth $150,000 (the residual value). Buildings costing $45,000 with an estimated useil life of 20 years were erected on the site. Because of the remote location, the buildings have no residual value. The company expects that all the usable ore can be mined in eight years. During its rst year of operation, the company mined 1,000,000 tons of ore and at the end of the year had an inventory of 200,000 tons.
