$500,000 Annual Exempt Profit Deduction / Dollars only
Each associated group of mine operators is eligible for an annual exempt profit deduction of $500,000. The exempt profit deduction is prorated for short taxation years and may be reduced further where a mine operator has a partial interest in a mine or where the operator ceases production in the taxation year for a period exceeding 60 days.
If your mining operations include a remote mine(s), calculate separately your profits from remote and non-remote mines on page 2 and prorate the annual exempt profit deduction between the two categories of mines using the formulae in E and F below.
An operator's total Annual Exempt Profit Deduction is the lesser of the following amounts:
1 / Short taxation year [s.3(2)(a)]
$500,000 X / No. of days in taxation year / ...... / = / A

§  up to 100% of the UCC of the assets provided that it does not exceed the operator’s profit for the taxation year from the new mine or major expansion (attach calculation). / 2.

a. 30% of the original capital cost for mining assets not previously used in mining operations (15% for other mining assets), and

Determination of Processing Allowances / Dollars only
Non-remote mines Remote mines
Use this schedule to compute the deduction for non-remote mines and remote mines by checking the applicable box above. Include only the cost of processing assets used for each category of mines.
The processing allowance applies to processing assets as constructed only to the extent that they remain in use after construction. Allowance is suspended on processing assets that are not fully completed within eight years after the date of commencement of construction. Allowance claimed on assets as constructed, but not in use must be supported by a progress report showing work done and monies expended on the assets during the taxation year [S. 9(3) and (4) of Reg. 769]. / The minimum and maximum allowance is neither less than 15% nor more than 65% of profit before processing allowance from the applicable column on page 2, Line 240.
Where an operator’s mining operations includes a remote mine, the cost of processing assets must be classified as either remote or non-remote based on their use. The processing allowance for the year in respect of a remote mine is to be computed separately on this form based on processing assets used for the remote mine (including those reclassified from non-remote mines) as if the mine operator had no interest in any mine other than the remote mine during the taxation year [S. 3(8)].
