Mesteña Grande Uranium Project (Alta Mesa ISR Project area) PEA: $154M NPV, $108M Capex
enCore Energy Corp.'s Mesteña Grande Uranium Project (Alta Mesa ISR Project area) 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 area) has reported Preliminary Economic Assessment (PEA) results for the uranium (u3o8) 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. All-in sustaining costs are pegged at 25.49 USD/lb U3O8. 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. Metallurgical recovery averages 60%.
Resources and ownership. Royalties and streams: Cumulative 3.6% surface and mineral royalty ($30.0 M or $3.60 per pound U3O8). State of Texas ad valorem property tax $2.5 M ($0.30/lb). Total Federal income tax estimated at $90.1 M ($10.82/lb)..
These figures are extracted from enCore Energy Corp.'s technical disclosures and reflect the most recent PEA on file. Compare this project against other developers and producers in our project economics database, and always verify the numbers against the original technical report before making any investment decision.

A PEA sits at the bottom of the confidence ladder, so the first thing to establish about this Texas uranium project is how little weight its numbers can carry. Scoping-level studies lean on inferred material and attach a plus or minus 50% band to the capital estimate, which means the $154M after-tax NPV should be read as a direction of travel rather than a valuation. On that basis it ranks above only 9% of the 11 uranium projects we track: near the bottom of a peer set, not an outlier in either direction. The study's own $85.48 per lb LOM sales price is the single assumption that carries the most leverage here, and it deserves to be stress-tested rather than taken at face value.
The constraint that decides this one is funding, not geology. Initial capex of $108M is 70% of NPV, moderately capital-intensive and lower than 82% of the tracked uranium peers, so the build itself is not unusual for the sector. The problem is scale: that $108M is roughly half the company's entire US$197M market cap. A micro-cap cannot absorb a build of that size quietly, and the realistic routes are equity dilution, debt, a partner, or a staged approach, each of which changes the returns an equity holder actually keeps. The NPV sitting at about 0.8x market cap cuts both ways: it can mean the asset is unrecognised, or that the market is discounting financing, dilution and the fact that this is one of 12 projects the company is carrying.
Texas is a favourable jurisdiction for permitting and infrastructure, which removes one common overhang but does nothing for the capital gap. The question that settles it: can this company fund $108M without diluting away the value the NPV represents?
