**NEWS RELEASE** 

**NASDAQ:EU** 

**TSXV:EU** 

**September 2, 2025** 

**<u>www.encoreuranium.com</u>**

**enCore Energy Corp. Announces the Dewey Burdock ISR Uranium Project Approved for United States Government Fast-Track Permitting; First South Dakota Critical Minerals Project Added to Fast-41** 

**DALLAS, September 2, 2025 – enCore Energy Corp.** (NASDAQ: EU) (TSXV: EU) (the "Company" or "enCore"), America's Clean Energy Company<sup>™</sup>, announced today that its Dewey Burdock ISR Uranium Project ("Dewey-Burdock Project"), located in South Dakota, has been approved for inclusion in the Fast-41 Program by the U.S. Federal Permitting Improvement Steering Council ("Permitting Council"). This is a component of the implementation of President Trump's Executive Order on Immediate Measures to Increase American Mineral Production. The Company's Dewey-Burdock Project received its Source and Byproduct Materials License in 2014, from the Nuclear Regulatory Commission ("NRC"), now under timely renewal, and will work with the NRC as the lead agency for federal permitting. enCore's objective is to advance the Dewey Burdock Project into development and operation utilizing the In-Situ Recovery ("ISR") uranium extraction process.

Under the Executive Order, the Permitting Council identifies priority infrastructure and critical mineral projects to receive accelerated permitting review. The addition of the first South Dakota ISR project supports the domestic uranium production focus of the United States. This focus enables the development of essential clean energy, extracted through environmentally responsible ISR technology, to provide affordable, reliable domestic energy. To learn more, please visit the Federal Permitting Dashboard: <u>Dewey Burdock ISR Uranium Project \| Permitting Dashboard</u>

Executive Chairman, William M. Sheriff, stated: "enCore Energy is honored to see the Dewey Burdock Uranium Project selected as a Fast-41 Project and we look forward to working with the Permitting Council and the NRC to advance the project in an open and transparent process. Dewey Burdock plays an important role in supporting the U.S. nuclear fuel supply chain with domestically produced uranium for many years into the future. As the first critical mineral extraction project selected within the State of South Dakota we also look to working with the state government, tribal governments and local communities as we focus on building a stronger domestic supply of clean and affordable energy and providing economic stimulus to southwest South Dakota."

**About the Dewey Burdock ISR Uranium Project** 

The Dewey Burdock ISR Uranium Project ("Dewey Burdock Project), wholly owned by enCore, is an advanced-stage uranium project located in Custer and Fall River counties in South Dakota. The Dewey Burdock Project will recover uranium from subsurface sandstone ore bodies through ISR technology, which utilizes a chemical-free water based solution in the production wellfield to dissolve uranium minerals in place and then pumps the uranium-bearing solution to a central processing plant for recovery. The use of ISR technology allows for minimal surface disturbance compared to conventional open-pit or underground uranium mining. The project consists of wellfield areas, a central processing plant, supporting infrastructure and environmental protection systems.

The Company's Dewey-Burdock Project received its Source and Byproduct Materials License SUA-1600 on April 8, 2014, from the NRC, covering 10,580 acres. The Company controls the mineral and surface rights for the area pertaining to the NRC license. With the approval of Fast-41, enCore's objective is to advance the Dewey-Burdock Project into development and operation as an ISR uranium extraction project.

Notes:

1. Effective date of mineral resource is October 8, 2024.

2. enCore reports mineral reserves and mineral resources separately. Reported mineral resources do not include
mineral reserves.

3. The geological model used is based on geological interpretations on section and plan derived from surface
drillhole information.

4. Mineral resources have been estimated using a minimum grade-thickness cut-off of 0.20 ft% U<sub>3</sub>O<sub>8</sub>.

5. Mineral resources are estimated based on the use of ISR for mineral extraction.

6. Inferred mineral resources are estimated with a level of sampling sufficient to determine geological continuity
but less confidence in grade and geological interpretation such that inferred resources cannot be converted to mineral reserves.

7. Mineral resources that are not mineral reserves do not have demonstrated economic viability.

John M. Seeley, Ph.D., P.G., C.P.G., enCore's Chief Geologist, and a Qualified Person under Canadian National Instrument 43-101 and S-K 1300, has reviewed and approved the technical disclosure in this news release on behalf of the Company.
