Answer:
$450,000
Step-by-step explanation:
estimated silver deposit 500,000 ounces
cost $1,500,000
depletion expense per ounce of silver = deposit cost / estimated reserves = $1,500,000 / 500,000 ounces = $3 per ounce of silver
since Lucky Strike extracted 150,000 or silver, its depletion expense = 150,000 ounces x $3 per ounce = $450,000
Depletion expense is used when companies extract natural resources, e.g. mines, oil and gas. Generally the cost of the total deposit or reserve includes exploration and development costs which are generally capitalized and expensed according to the estimated reserves.
