Variance vs report+0.7%

Re-created NPV: the report's after-tax NPV recalculated in our model from the report's published inputs, using the report's own tax, working-capital and timing treatment. It shows how closely the published economics can be reproduced. It does not confirm that the report's calculations or assumptions are correct, and it is not our base case.

What the rebuild process surfaced

The study prints a single total-taxes row, with no pools, allowances or credit timing. Its taxes are C$140M below statute over the life of mine, with refunds in Years 1 and 2: about C$340M of deductions it does not name. The model builds tax from federal and Newfoundland and Labrador statute; on that basis the value is below the study's, while pre-tax the two are close. With the study's published taxes selected, the model lands 0.7% above the report.
