Answer:
Ore deposit depletion and Mining machinery depreciation Journal entries
Dr Depletion charge (Ore deposits) 405,528
Cr Accumulated depreciation 405,528
Dr Depletion charge (Ore deposits) 23,268
Cr Accumulated depreciation 23,268
Explanation:
Preparation of the year-end entries to record both the ore deposit depletion and the mining machinery depreciation of Montana Mining Co
Depletion of natural resources can be defined as the way in which the cost of natural resources is apportioned upto the period when it will be utilized which is why they are shown at cost in balance sheet.
The entry is to record depreciation charged on ore deposit depletion. Therefore To record this entry we have to debit depletion charges, and credit accumulated depreciation
Dr Depletion charge (Ore deposits) 405,528
Cr Accumulated depreciation 405,528
Computation of depletion cost per unit:
The depletion cost per unit can be calculated by dividing the net cost of the ore with the total units of capacity :
Depletion/units = Cost - Salvage/ Total unit of capacity
$3,721,000/1,525,000 tons
=$2.44
Hence, depletion per unit is $2.44.
Computation depletion amount on ore deposit:
The depletion amount on ore deposit can be calculated by multiplying the cost per depletion unit with the number of units utilized:
Depletion =Cost/Unit ×Units Utilized
$2.44×166,200 tones
=$405,528
Hence, depletion expenses on ore deposit amounts to $405,528.
The pass entry to record depreciation charged on mining machine :
Dr Depletion charge (Ore deposits) 23,268
Cr Accumulated depreciation 23,268
Computation of depreciation cost per unit:
The depletion cost per unit can be calculated by dividing the net cost of the ore with the total units of capacity :
Depletion/units = Cost - Salvage/ Total unit of capacity
$213,500/1,525,000 tons
=$0.14
Hence, depreciation per unit is $0.14.
Computation of depreciation amount on ore deposit:
The depletion amount on ore deposit can be calculated by multiplying the cost per depletion unit with the number of units utilized:
Depletion =Cost/Unit ×Units Utilized
$0.14×166,200 tones
=$23,268
Therefore the depreciation expenses on ore deposit amounts to $23,268
