What the rebuild surfaced. Two opposite effects net to the difference. The study's printed revenue is US$410.75M below payable metal times price in Years 5-27, all in the copper and silver credits, with no selling term to explain it; and its published taxes cannot be rebuilt from statute. The model takes revenue at the stated selling terms and tax from federal and Québec statute; with both of the study's printed figures selected, it lands 0.1% above.
