$CGAU Mount Milligan Mine – 5x Improvement from 2020 to 2025
Ever wonder how a single mine can go from a modest 9-year life to a 20-year cash machine? Centerra’s Mount Milligan mine did just that. A fresh 2025 study flipped the script: new drilling and steeper pit slopes quintupled measured + indicated resources—from about 125 Mt to more than 670 Mt—and doubled reserves, while higher metal prices and a massive expansion plan boosted the after-tax NPV from
$342 M to nearly
$1.X.5 B. But those gains come with lower grades, a fourfold increase in capital spending and huge sensitivity to copper, gold and currency swings. Curious how a mine reinvents itself? Read on to see the numbers and the risks.
