Encore Energy Continues Wellfield Expansion at the Alta Mesa Uranium Project in South Texas - 2025

Uranium (Nuclear Minerals) / Exploration, Mining, Marketing, & Acquisitions

enCore Energy Corp. provided continued positive results from on-going improvements to wellfield operations at the Alta Mesa Uranium Central Processing Plant ("CPP") and Wellfield (see EU NR dated April 7, 2025). 

The Alta Mesa CPP and Wellfield expansion highlights include:

• Wellfield development continues to show positive results with a total of 32 wells, 15 extractors and 17 injectors installed and operational with uranium-bearing solution scheduled to be piped to the Alta Mesa CPP by April 23, 2025. This current rate of under two days per installed well is the best in the Company’s history at the the Alta Mesa Project (more);
  
  
• Installation of PathCAD™ wellfield simulation and design software providing enCore the ability to model wellfield flow for current and future wellfields. PathCAD™ software is proven to provide for improved wellfield management, efficient wellfield planning, operations and optimization of uranium extraction;
  
  
• Wellfield 8 ("PAA-8"), planned for uranium extraction following the currently operational Wellfield 7 is now renamed Wellfield 3-Ext ("PAA-3 Extension"). The original plan to develop Wellfield 8 is altered due to new delineation drilling which indicates the uranium mineralization occurs within the same ore horizon and partially within the boundary of the existing monitor well ring of the past-producing Wellfield 3 ("PAA-3"). Modelling Wellfield 3-Ext as an extension of Wellfield 3 is expected to reduce permitting timelines and wellfield installation costs while extending the existing monitor well ring. This approach also provides the ability to capture uranium stranded within the previously operated Wellfield 3;
  
  
• Alta Mesa wellfield optimization training and updated procedures are on-going. The enhanced procedures are positively impacting the productive life of existing wellfields and is expected to enhance future wellfield operations and total uranium capture.

About the Alta Mesa Uranium CPP and Wellfield ("Alta Mesa Uranium Project")

The Alta Mesa Uranium 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.
