enCore Energy reports uranium oxide suitable for wellfield at Alta Mesa East
enCore Energy Corp. announced that drill hole 12-20 at the Alta Mesa East Project intersected 8.5 feet of uranium oxide mineralization grading 0.199% U3O8, yielding a Grade Thickness (GT) of 1.69. The company deems a GT of 0.3 suitable for wellfield inclusion. Of 20 recent drill holes, 12 were mineralized, with six returning GT values between 0.43 and 1.76.

enCore Energy Corp. reported that a uranium oxide well drilled at the Alta Mesa East Project is suitable for inclusion in the wellfield. The company identified drill hole 12-20 as containing significant mineralization, intersecting 8.5 feet of material grading 0.199% U3O8. This resulted in a Grade Thickness (GT) of 1.69, exceeding the company's threshold of 0.3 for wellfield inclusion. The Alta Mesa East Project is located immediately adjacent to the established Alta Mesa Wellfields and Central Processing Plant in South Texas.
The ongoing drilling program targets the continuation of productive roll fronts from several Alta Mesa Wellfields. The latest results encompass 20 drill holes, with 12 found to be mineralized. Six of the ten specific drill holes analyzed returned GT values ranging from 0.43 to 1.76. The program has discovered uranium mineralization within sands at average depths between 400 and 460 feet, and within sands between 480 and 520 feet.
Drilling Progress and Scope
The drill program continues with six rigs typically operating on 400 to 500 foot spacing and reaching an average depth of 600 feet. Seven widely spaced east-west fences of drilling are underway to characterize the mineralization across the entire property. The company aims to define the extent of the resource through this systematic approach.
Key Drilling Results
| Drill Hole | Depth (feet) | Mineralization (feet) | Grade (% U3O8) | GT Value |
|---|---|---|---|---|
| 12-20 | 487 | 8.5 | 0.199 | 1.69 |
| Range (6 holes) | - | - | - | 0.43 – 1.76 |
