The after-tax IRR is not disclosed, but the NPV of $541M at roughly 1.3x market cap signals a project that could deliver meaningful value if de-risked—but the gap is two-sided. It may reflect the market’s skepticism on financing, permitting, or jurisdiction risk for a single-asset junior, not just unrecognized upside. The study’s copper price assumption of $3.25/lb sits dramatically below the current spot of $6.36/lb, which implies the returns are likely optimistic under today’s pricing; conversely, if the study’s price proves conservative, the upside could be material. The 22-year mine life supports long-duration cash flows, but capital intensity relative to NPV and market cap is the key funding risk—dilution is a real concern for a developer of this scale. The single most important watch-item is whether the company can secure financing without excessive equity dilution, given the large capex relative to its current market valuation.
