enCore Energy Extends Uranium Mineralization 3,700 Feet at Alta Mesa East

Executive Summary
- enCore Energy reported initial exploration drilling results from its 5,900-acre Alta Mesa East (AME) property, confirming uranium mineralization extending over 3,700 feet east from existing wellfields.
- Of 17 drill holes reported, 10 contained mineralization, with six achieving Grade Thickness (GT) values between 0.351 and 2.297, successfully meeting the >0.3 GT threshold required for ISR wellfield inclusion.
- Six drilling rigs are actively advancing the program across multiple sandstone horizons within the Pliocene Goliad Formation, targeting Middle C and Lower C sands at depths of 400–520 feet.
- Management states that ongoing results will guide permitting and future ISR expansion plans, with additional results pending.
Material Impact
- The results are fully in line with expectations established during the August 2025 land acquisition and drilling campaign announcement.
- No material surprises in grade, thickness, or geological continuity; the GT values are consistent with historical Alta Mesa data and management's internal models.
- The update validates the strategic pivot under new CEO Richard Little to aggressively develop AME, but does not immediately alter near-term production guidance, cost structure, or financial projections.
- The news is incremental, confirming that the company’s ISR expansion pipeline remains viable and on track for future wellfield additions, but lacks the unexpected catalyst required to move the stock materially.
