07:33 AM EDT, 10/15/2025 (MT Newswires) -- enCore Energy , an American clean energy company, was at last look up near 13% in US premarket trade Wednesday after saying "important new uranium discoveries have been made in areas in or near existing wellfields".

According to a statement, these discoveries have been made as a result of a major ongoing re-analysis of thousands of historic drill holes from across the Alta Mesa In-Situ Recovery Uranium Project that began in April 2025. It said this more granular and detailed evaluation has identified uranium mineralized roll fronts in at least three areas to date. Follow up drilling by enCore has delineated these new roll fronts with drilling continuing to determine the extents of each, it added.

Wednesday's statement said: "This additional roll front uranium mineralization has been discovered in close proximity to known and already exploited roll fronts. One of these new roll fronts has progressed such that it has now advanced to permitting as Wellfield 3 Extension. Mineralized roll fronts have also been found overlying the past productive mineralization in Wellfield 4 with at least two new roll fronts discovered to date, each extending more than 2500 feet in length with both included in the existing permit authorization."

"This newly discovered mineralization lies at a depth of 320 to 345 feet, almost 200 feet above the previously exploited roll front. This shallow mineralization makes for shorter drill times with less footage required, less cement and shorter casing intervals resulting in significant cost savings in delineation and extraction versus deeper mineralization. A third area extending south from the previously exploited mineralization in Wellfield 1 continues to expand with additional ongoing drilling."

It added this granular re-analysis of previous drill data is expected to continue through the end of the year with follow-up delineation drilling continuing into 2026. This drilling is in addition to the major drill program, expected to commence in the next few weeks, on the recently acquired Alta Mesa East Property which hosts the extensions of roll front uranium mineralization from several of the Wellfields to the west on the established Alta Mesa Project.
