DALLAS, April 7, 2025 /PRNewswire/ -- enCore Energy (NASDAQ: EU) (TSXV: EU) (the "Company" or "enCore"), announced today the results of the most successful month at the Alta Mesa In-Situ Recovery Uranium Central Processing Plant ("CPP") since commencing operations in June 2024. Following previously announced improvements to operations (see EU NR dated March 13, 2025) with the goal of expanding uranium extraction, decreasing unnecessary costs and increasing efficiency, the Company captured 50,000 pounds of uranium ("U₃O₈") in the last 26 days in March 2025.  With a healthy treasury including unencumbered cash, inventory and marketable securities of ~$40 million USD, the Company continues to improve Alta Mesa CPP operations and the wellfield development program, which is now on track to meet 2025 contract projections. The Company also announced the appointment of Rob Willette, Acting Chief Executive Officer ("A/CEO"), to the Board of Directors and the promotion of Daniel Calderon to Director of Texas Operations.  Mr. Willette will hold the Board seat dedicated to the Chief Executive Officer until such time a permanent appointment is made.

William M. Sheriff, Executive Chairman of enCore Energy stated: "The improvements at the Alta Mesa CPP are the result of a true team effort, led on site by an outstanding group of dedicated professionals. Mr. Calderon has taken on a key leadership role, managing day-to-day operations at both the Rosita and Alta Mesa CPP's. We also want to recognize the invaluable contributions of two of our Directors—Dr. Dennis Stover and Mark Pelizza—who bring decades of experience in In-Situ Recovery (ISR) operations. Their ongoing commitment and additional efforts have been instrumental in enhancing site operations and advancing permitting initiatives at the Texas state level."

Mr. Sheriff further added: "Mr. Willette has provided immense value to the Company in his role of Chief Legal Officer, and now A/CEO, assisting greatly with the transition to a U.S.-domiciled company. His understanding of the regulatory environment in the U.S. has been of great benefit to our team. I am pleased he has agreed to join the Board to provide continuity at the leadership level."

Alta Mesa CPP and Project highlights include:

• Uranium capture of 50,000 pounds of uranium has been realized at the Alta Mesa CPP between March 6^th and March 31^st with one day offline due to power failures associated with torrential rain;
• Average daily capture rate for the last 26 days of March 2025 was in excess of 1,900 pounds of uranium per day; this is the highest rate since the plant returned to operations in June of 2024;
• In 2025, the Company has, as of this date, delivered 290,000 pounds of uranium under its contracts with utility companies. An additional 365,000 pounds of uranium is expected to be delivered for contracts through 2025. At the current extraction rate, it is expected that the Company will not purchase additional uranium in the market to meet 2025 contractual commitments;
• The Company accelerated its August 2025 contract delivery requirements to May 2025 due to the improved uranium capture at the Alta Mesa CPP;
• A total of 21 drill rigs are now in operation at the Alta Mesa Project; 14 drill rigs dedicated to wellfield installation and advancement of Wellfield 7 ("PAA-7"). 4 drill rigs are at Wellfield 8 ("PAA-8") focused on development drilling; 2 drill rigs are focused on Alta Mesa exploration and 1 drill rig is located at Upper Spring Creek;
• Initial preparatory work commenced at the permitted Wellfield 6 ("PAA-6"), which was in operation in 2013 briefly, prior to operations at Alta Mesa being placed on stand-by due to low uranium prices. The Company looks forward to resuming operations of the fully permitted wellfield in Q4 2025 following necessary refurbishment and repairs.

The Company will continue to accelerate wellfield development and intends to source up to 12 additional drill rigs, with the target of at least 30 drill rigs operating at its South Texas projects.  This target is expected to provide the Company with the optimal number of drill rigs to accelerate extraction and advance wellfield development at the Alta Mesa Project.

About the Alta Mesa Uranium CPP and Wellfield
The Alta Mesa Project hosts a fully licensed and constructed ISR Central Processing Plant and operational wellfield located on 200,000+ acres of private land and mineral rights in and regulated by the state of Texas. Total operating capacity at the Alta Mesa CPP is 1.5 million lbs. uranium per year with additional drying capacity of 0.5 million lbs. The Alta Mesa Project operates under a 70/30 joint venture with Boss Energy Limited (ASX: BOE; OTCQX: BQSSF) that is managed by the Company.

The Alta Mesa CPP historically produced nearly 5 million lbs. of uranium between 2005 and 2013 when production was curtailed as a result of low prices. The Alta Mesa Project utilizes well known ISR technology to extract uranium in a non-invasive process using natural groundwater and oxygen. Currently, oxygenated water is being circulated in the wellfield through injection or extraction wells plumbed directly into the primary pipelines feeding the Alta Mesa CPP. Expansion of the wellfield will continue with production to steadily increase from the wellfield as expansion continues through 2025 and beyond.
