Mantoverde (MV Optimized) Feasibility Study: $176M Capex
Capstone Copper Corp.'s Mantoverde (MV Optimized) in Atacama Region, Chile has a Feasibility Study outlining initial capital of $176M.
Capstone Copper Corp.'s Mantoverde (MV Optimized) has reported Feasibility Study results for the copper project in Atacama Region, Chile. It reflects Capstone Copper Corp.'s (CS.TO) latest disclosed economics for the asset.
Economics. Initial capital expenditure is estimated at $176M. Economics are based on $4.10/lb Cu and $1,800/oz Au (MV-Optimized capital intensity basis).
Production and mine plan. The project envisions an open-pit (sulphide concentrator + sx-ew cathode) operation. Average annual production is approximately 20000 t Cu (incremental avg annual, first 10 years). Average head grade is 0.65% Cu (Q3 2026 sulphide grades). Metallurgical recovery averages 87.7%.
Resources and ownership. Mineral resources: Sulphides: ~1.0Bt M&I (incl. reserves), ~0.6Bt Inferred; Oxides: ~0.4Bt M&I (incl. reserves), ~0.1Bt Inferred (district); slide 6 breakdown: Sulphides 0.4Bt Reserve, 0.2Bt M&I, 0.6Bt Inferred; Oxides 0.2Bt Reserve, 0.2Bt M&I, 0.1Bt Inferred.
These figures are extracted from Capstone Copper Corp.'s technical disclosures and reflect the most recent Feasibility Study on file.

Our Analysis
- Initial capex
- $176M
costlier than 17% of 53 projects we track
- Study price assumption
- $4.10/lb Cu and $1,800/oz Au (MV-Optimized capital intensity basis)
- Spot copper today
- $6.48/lb
Measured against the 53 copper projects we track, this one sits in the pack rather than ahead of it: initial capex of $176M is lower than 83% of them, which puts the build in the cheaper quartile without making it distinctive. For an investor, that rank means the differentiator is not scale, jurisdiction or capital efficiency on its own, because none of those is an outlier. What separates this asset is the combination: a modest build in Chile's Atacama Region, a mining-friendly jurisdiction, carried by a diversified mid-cap with ten projects in our coverage and a market cap of roughly US$6.15B. The build cost is small relative to that market cap, and that is the sharpest funding signal here: this is a cheque the company can write without the dilution or project-finance scramble that sinks single-asset developers.
The confidence behind these numbers matters as much as the numbers. This is a feasibility study, the build-ready estimate typically carrying a plus or minus 15% band, so the capex and returns deserve more weight than a scoping-level PEA would earn. The project is already at production stage, which further narrows the execution gap between study and cash flow.
The caution sits in the price deck. The study is built on $4.10/lb copper and $1,800/oz gold, while copper trades at $6.48/lb today. That gap means the published economics were struck well below the current market, so the returns as presented are not stretched by an optimistic assumption; if anything they understate what spot would deliver. The question that decides this project is not whether it clears its hurdle at $4.10 copper, but whether the company converts a cheap, feasibly-defined build into production on schedule, because at this size the value is in execution, not in the headline.
