Depletion

On July 1, 2019, Amplex Company purchased a coal mine for $2 million. The estimated capacity of the mine was 800,000 tons. During 2019, Amplex mines 10,000 tons of coal per month and sells 9,000 tons per month. The selling price is $30 per ton and production costs (excluding depletion and depreciation) are $8 per ton.

At the end of the mine's life, Amplex estimates that the present value of the cost to restore the land is $300,000, after which it can be sold for $100,000. Amplex also purchased some temporary housing for the miners at a cost of $170,000. The housing has an expected life of 10 years but is expected to be sold for $10,000 at the end of the mine's life. The housing is depreciated using the activity method. Amplex uses the FIFO cost flow assumption and its discount rate is 10%.
