The maximum amount that operators can deduct as a depreciation allowance in respect of class 1A, class 2A and class 3A property in calculating the mine-mouth output value is the least of the following amounts:

  • the capital cost of the property of the class that was used in the operation of the mine, multiplied by the depreciation rate that applies to the property;
  • the undepreciated capital cost of the property of the class that was used in the operation of the mine at the end of the fiscal year;
  • zero (where an operator no longer owns property of the class at the end of the fiscal year).

The maximum amount that operators can deduct as a depreciation allowance in respect of class 4A property in calculating the annual earnings from a mine is 30% of the undepreciated capital cost of the property of that class that is used in the operation of the mine at the end of the fiscal year. If an operator no longer owns property of the class at the end of the fiscal year, the allowance is equal to zero.

If an operator deducts an amount as a depreciation allowance in calculating the mine-mouth output value, the operator must deduct the same amount in calculating the annual earnings from the mine.

Operators can deduct the depreciation allowance in respect of class 4A property for a fiscal year only if they deducted the maximum amount in respect of class 1A, class 2A and class 3A property for the same fiscal year.
