Question
Zvinakis Mining Company paid $300,000 for the rights to mine lead in southeast Missouri. The cost to drill and erect a mine shaft was $2,500,000, and equipment to process the lead ore before shipment to the smelter was $2,010,000. The mine is expected to yield 2,000,000 tons of ore during the five years it is expected to be operating. The equipment has an estimated residual value of $160,000 when mining is concluded. The mine started operations on April 30, 2018. In 2018, 400,000 tons of ore were extracted, and in 2019, 800,000 tons were mined. Required: 1. Compute the depletion rate and the units-of-production depreciation rate. 2. Compute depletion and depreciation for 2018 and 2019.
Explanation / Answer
Answer:
1. Compute the depletion rate and the units-of-production depreciation rate.

2. Compute depletion and depreciation for 2018 and 2019.
Depletion for 2018 and 2019
2018 (400,000*1.4)
560000
2019(800,000*1.4)
1120000
Depreciation for 2018 and 2019
2018(400,000*0.925)
370000
2019(800,000*0.925)
740000
