Centerra Gold Secures Mount Milligan Permits Through 2035 with 10% Expansion, Reveals $1.1B Kemess PEA
Centerra Gold received amended permits extending Mount Milligan operations through 2035 with a 10% throughput expansion in 2028 and is studying a life extension to 2045. Its Kemess PEA forecasts after-tax NPV5% of $1.1 billion and 16% IRR, with 15-year output of 171 koz gold and 61 Mlb copper at $971/oz AISC.
1. Robust Earnings Surprise History Suggests Potential Upside
Centerra Gold has exceeded consensus estimates in four of its last five quarterly reports, delivering an average earnings surprise of 12%. Key drivers include beat-and-raise guidance in both gold production and all-in sustaining costs, as well as consistent outperformance at its Mount Milligan operation. Analyst models forecast gold equivalent production growth of 8% year-over-year, while the company has trimmed unit costs by more than 5% over the same period, creating a favorable setup for another positive surprise when results are released.
2. Permit Amendments Secure Mount Milligan Operations Through 2035
In late January, Centerra received amended environmental permits for its British Columbia Mount Milligan mine, authorizing a 10% expansion in plant throughput beginning in 2028 and increased stockpile capacity. The expedited permitting process, one of four projects selected by the provincial government, underpins a mine life extension to 2035 and sustains over 1,000 direct jobs in northern communities. Ongoing engineering studies are targeting a further extension to 2045 under a fully funded $186 million growth capital plan, reinforcing long-term cash flow visibility.
3. Kemess PEA Underpins Growth with $1.1 Billion NPV and 16% IRR
Centerra’s Preliminary Economic Assessment for the Kemess project outlines an after-tax net present value of $1.1 billion (5% discount) and a 16% internal rate of return based on a 15-year mine life. The study leverages existing infrastructure and an integrated open-pit and underground mining strategy, delivering average annual production of 171,000 ounces of gold and 61 million pounds of copper (267,000 gold-equivalent ounces) at an all-in sustaining cost of $971 per ounce. Initial capital requirements total $771 million, with an incremental $277 million to bring underground operations online, positioning Kemess as a cornerstone of Centerra’s organic growth pipeline.
