**Accounting for Extractive Industries: A Comprehensive Case Study**

*Introduction:*

The accounting for extractive industries involves unique challenges due to the nature of their operations, including exploration, evaluation, and extraction of non-renewable resources such as oil, gas, and minerals. In this case study, we'll explore the accounting principles applied by XYZ Mining Corporation, a company engaged in the extraction of precious metals.

*Case Study: XYZ Mining Corporation*

**Step 1: Exploration and Evaluation Phase**

XYZ Mining Corporation embarks on an exploration and evaluation phase to identify potential mineral resources. Costs incurred during this phase, such as geological studies and drilling, are capitalized as exploration and evaluation assets.

**Step 2: Development and Extraction**

Upon identifying economically viable resources, XYZ Mining Corporation moves to the development phase. Costs incurred to develop the mine, including construction and infrastructure, are capitalized. Extraction costs, such as labor and machinery, are also capitalized until the resource becomes economically viable.

**Step 3: Depreciation and Amortization**

The capitalized exploration and development costs are depreciated or amortized over the useful life of the respective assets. The method used, whether straight-line or units-of-production, depends on the nature of the asset.

**Step 4: Impairment Testing**

XYZ Mining Corporation conducts regular impairment testing on its exploration and evaluation assets and mining assets. If there are indicators of impairment, the carrying amount of the assets is adjusted accordingly.

**Step 5: Revenue Recognition**

Revenue from the sale of extracted minerals is recognized when control of the goods is transferred to the customer. This typically occurs when the minerals are delivered to the customer, and payment is reasonably assured.

*Objective Type Question:*

**Fill in the blanks: XYZ Mining Corporation conducts regular ________ on its exploration and evaluation assets and mining assets. If there are indicators of impairment, the carrying amount of the assets is adjusted accordingly.**

A) Market analysis B) Impairment testing C) Exploration studies D) Resource evaluation

Please choose the correct option (A, B, C, or D) based on the information provided in the case study.
