Snowline Gold Sets the Stage for Multi-Billion Dollar Yukon Mine
Snowline Gold’s Valley project in Yukon could redefine Canada’s mining future with massive gold reserves, low costs, and a multi-billion-dollar NPV.

Snowline Gold has unveiled its first-ever Preliminary Economic Assessment (PEA) for the Valley deposit at its Rogue project in Yukon, and the results are as striking as the gold grades it’s pulling out of the ground. This isn’t just another junior miner with a speculative drill hole and lofty dreams. This is a company laying down a serious claim for a world-class open-pit gold mine with the numbers to back it up. With a 20-year mine life and 6.8 million ounces of gold production projected, Snowline’s vision for Valley has suddenly become a lot more tangible.
The numbers are staggering. Average annual production during the first five years is forecasted at 544,000 ounces of gold, and that comes with an all-in sustaining cost of just $569 per ounce over the same period. For context, that’s among the lowest in the industry, giving Snowline a distinct edge. Over the entire life of mine, the AISC rises modestly to $844 per ounce, still comfortably below most global peers. Using a conservative base-case gold price of $2,150 per ounce, the project yields a post-tax net present value (NPV) of C$3.37 billion and an internal rate of return (IRR) of 25%. The company’s valuation explodes upward if you use a more bullish scenario. At $3,150 gold, the NPV climbs to C$6.8 billion and the IRR jumps to 37%, a clear signal that Valley is leveraged beautifully to a rising gold price.
What’s equally impressive is how quickly the project pays back its initial capital of C$1.7 billion. With a projected payback period of just 2.7 years, Snowline is showing off the rare combination of scale, efficiency, and profitability. This isn’t a far-off vision either. Mineralization at Valley starts right at surface and remains open in several directions, giving the project even more runway as drilling and engineering continue. The current PEA is based on an indicated resource of 164.2 million tonnes grading 1.48 grams per tonne for 7.8 million ounces of contained gold, with an additional inferred resource of 66.4 million tonnes grading 1.12 grams per tonne for another 2.4 million ounces. That places Valley squarely among the largest undeveloped gold projects in Canada.
