Cotabambas Project Economics: $600M Capex
Panoro Minerals Ltd.'s Cotabambas in Peru (Apurimac region) has an economic study outlining initial capital of $600M.
Panoro Minerals Ltd.'s Cotabambas has reported economic study results for the copper-gold (cu/au) project in Peru (Apurimac region). It reflects Panoro Minerals Ltd.'s (PML.V) latest disclosed economics for the asset.
Economics. Initial capital expenditure is estimated at $600M. Economics are based on CuEq calculated using US$5.00/lb Cu, US$4,000/oz Au, and US$60/oz Ag.
Production and mine plan. The project envisions an open-pit operation. The open-pit strip ratio is 0.65:1.
Resources and ownership. The company holds a 100% interest in the project.

Our Analysis
- Initial capex
- $600M
costlier than 69% of 443 projects we track
- Study price assumption
- CuEq calculated using US$5.00/lb Cu, US$4,000/oz Au, and US$60/oz Ag
- Spot copper today
- $6.77/lb
The first question is not whether this mine works, but who writes the $600M cheque. That initial capex sits about 1.4x the company’s entire US$431M market cap, and while that build cost ranks lower than 31% of the 443 projects we track, it is still far beyond what a small-cap can quietly finance. Realistic paths are a strategic partner taking a large equity stake, significant debt against a copper-gold stream, or a joint venture that cedes control. Any of those routes dilutes existing holders meaningfully, so the headline return is secondary to the terms of that capital raise.
The project economics are the supporting act, and they deserve a skeptical read given the setting. This is an exploration/development-stage asset in Peru’s Apurimac region, a mining jurisdiction with real potential but also permitting and community-relations friction that can delay or repriced builds. More importantly, the study prices copper at US$5.00/lb while today’s spot sits at US$6.77/lb. That gap works in the project’s favour, providing a cushion against cost overruns or grade shortfalls, but it also means the study’s base case is conservative by construction, and the market may be discounting the financing overhang rather than the commodity upside.
The two-sided read on valuation is straightforward: a large NPV relative to a US$431M market cap either signals an underappreciated asset or a market skeptical that the company can fund construction without destroying shareholder value. Given the 1.4x capex-to-cap ratio, skepticism is rational. The single question that decides whether this works is not the IRR, but whether management can secure $600M on terms that leave existing holders with a meaningful stake in the outcome. If they cannot, the project’s economics are irrelevant to the equity.
