In 2018, Green constructed a road to the silver mine costing P5,000,000. Improvements to the mine made in 2018 cost P750,000. Because of the improvements to the mine and the surrounding land, it is estimated that the mine can be sold for P600,000 when the mining activities are complete.
During 2019, five buildings were constructed near the mine site to house the mine workers and their families. The total cost of the five buildings was P1,500,000. Estimated residual value is P250,000. In 2017, geologists estimated 4 million tons of silver ore could be removed from the mine for refining.
During 2020, the first year of operations, only 5,000 tons of silver ore were removed from the mine. However, in 2021, workers mined 1 million tons of silver. During that same year, geologists discovered that the mine contained 3 million tons of silver ore in addition to the original 4 million tons. Improvements of P275,000 were made to the mine early in 2021 to facilitate the removal of the additional silver.
Early in 2022, an additional building was constructed at a cost of P225,000 to house the additional workers needed to excavate the added silver. This building is not expected to have any residual value.
In 2022, 2.5 million tons of silver were mined and costs of P1,100,000 were incurred at the beginning of the year for improvements to the mine.
Requirements:
Part (a) Calculation of Depletion from 2020 to 2022.
For 2020:
Calculation of Depletion per ton
Cost (Working Note 1) = 73,00,000.00
Residual Value (given)= 6,00,000.00
Estimated extraction (given)= 4 million tons = 40,00,000.00 tons
Depletion per ton=
Depletion for 2020= Number of tons withdrawn in 2020 Rate per ton
