Huasco Water - Stage 1 (Seawater Supply to Costa Fuego) PFS: $122M NPV, 19% IRR

A 19% after-tax IRR puts this water project in the bottom quartile of the 390 projects we track, above only 17% of them, and the NPV lands in much the same place: $122M, higher than 16% of 564 peers. That is the honest starting point. Nothing here is broken, but nothing stands out either, and an investor should read the numbers as mid-pack rather than as a mispricing waiting to close. The payback of 4.5 years reinforces the picture, longer than all but 12% of the 318 projects we score on that measure.

The constraint that matters is funding, and it is sharper than the headline returns suggest. Initial capex of $151M is 124% of NPV and roughly 0.7x the company's entire US$215M market cap. A build of that size against a micro-cap balance sheet cannot be absorbed quietly; it implies dilution, partner carry, or debt that will lean hard on a 19% return. The practical hurdle for a junior with little else to lean on is nearer 20% than the 15% a well-capitalised developer might accept, so this IRR sits just under the line where project finance gets comfortable. The PFS stage adds its own discount: a plus-or-minus 25% band on a pre-feasibility estimate is not a build decision, and the capex figure could move materially before it is.

Chile's Atacama Region is a genuinely favourable jurisdiction for development, with an established mining and infrastructure base, and that is worth real credit in how the numbers should be read. But jurisdiction does not fix a thin return. Water as a commodity also brings offtake and regulatory questions that a metal price does not. The NPV at 0.6x market cap is roughly in line rather than a gap, which reads as the market already having priced the asset rather than overlooked it. The question that decides this project: can a micro-cap fund $151M of capex without diluting the 19% return down to something the equity no longer rewards?
