Mesteña Grande Uranium Project (Alta Mesa ISR Project) PEA: $154M NPV, $108M Capex
enCore Energy Corp.'s Mesteña Grande Uranium Project (Alta Mesa ISR Project) in Brooks and Jim Hogg Counties, Texas, USA has a Preliminary Economic Assessment (PEA) outlining an after-tax NPV of $154M and initial capital of $108M.
enCore Energy Corp.'s Mesteña Grande Uranium Project (Alta Mesa ISR Project) has reported Preliminary Economic Assessment (PEA) results for the uranium project in Brooks and Jim Hogg Counties, Texas, USA. The study headlines an after-tax net present value of $154M at a 8% discount rate. It reflects enCore Energy Corp.'s (EU.V) latest disclosed economics for the asset.
Economics. The after-tax NPV is $154M using a 8% discount rate. Initial capital expenditure is estimated at $108M. Economics are based on Average LOM sales price of $85.48 per lb U3O8.
Production and mine plan. The project envisions an in situ recovery (isr) operation. Average head grade is 0.119% U3O8 (inferred resource grade). Metallurgical recovery averages 60%.
Resources and ownership. Royalties and streams: Cumulative 3.6% surface and mineral royalty; total $30.0 M or $3.60 per lb U3O8 at $85.48/lb.
These figures are extracted from enCore Energy Corp.'s technical disclosures and reflect the most recent PEA on file.

Our Analysis
- NPV after-tax
- $154M
higher than 42% of 12 projects we track
- Initial capex
- $108M
70% of NPV
costlier than 36% of 11 projects we track
- Study price assumption
- Average LOM sales price of $85.48 per lb U3O8
Against the twelve uranium projects we track, this one sits squarely in the middle: an after-tax NPV of $154M ranks it above 42% of that peer set. Nothing about the returns is an outlier in either direction, and for a diversified developer with eleven projects in its pipeline, that is the honest read. This is not the asset that carries the story; it is one line in a broader portfolio, and it should be valued that way.
The constraint that matters is scale. The company's market cap is roughly US$204M, a micro-cap, and the initial capex of $108M is about half of that entire equity value. A build of that size relative to the balance sheet cannot be financed quietly: it implies either a substantial raise, dilution, partnering, or debt, and each of those paths changes the equity story. Capex at 70% of NPV is moderately capital-intensive, and it is lower than 64% of the eleven uranium peers, so the project is not an extreme case on that measure. But the ratio that bites is capex against market cap, not capex against NPV.
Two further caveats deserve weight. This is a scoping-level PEA, which may rest on inferred resources and carries a capital estimate with a plus or minus 50% band, so the $108M figure could move materially in either direction before a feasibility study. And the economics assume an average LOM sales price of $85.48 per lb U3O8. That single input drives the NPV, so the return is best read as a sensitivity to it: a weaker realised price would compress the $154M figure, and the study offers no cushion beyond its own assumption. The jurisdiction, Brooks and Jim Hogg Counties, Texas, is a favourable one for permitting and infrastructure, which offsets some operational risk but does nothing for the funding gap.
The question that decides this project: can a US$204M company fund a $108M build without diluting away the value of a mid-pack NPV?
