ENCORE ENERGY ANNOUNCES EXPANSION OF THE ALTA MESA URANIUM PROJECT

EnCore Energy Corp. has acquired a 5,900-acre parcel of private land (Tacubaya), located immediately adjacent to, and east of, EnCore's Alta Mesa historical and producing wellfields and central processing plant. Tacubaya is expected to provide additional feed and longevity for the Alta Mesa in situ recovery (ISR) uranium central processing plant (CPP).

William M. Sheriff, executive chairman of EnCore Energy, stated: "On behalf of the board, I extend our congratulations to our land department, which worked for many months to assemble this strategic land acquisition that significantly expands the Alta Mesa uranium project. The compelling geology and location, immediately adjacent to, and on trend with, our active and past wellfields make this a key acquisition for EnCore. We will begin an aggressive exploration program, following up on mineralization discovered by Chevron in the late 1970s, which lies along projected trends extending from several of the wellfields at Alta Mesa."

Highlights for the Tacubaya acquisition include:

• Over 5,900 acres of private land consisting of mineral and surface leases with private parties located immediately adjacent to, and east of, EnCore's Alta Mesa uranium project;
• Tacubaya is a part of the Alta Mesa uranium project joint venture (JV) between EnCore Energy (70 per cent) and Boss Energy Ltd. (30 per cent);
• Tacubaya's uranium mineralization occurs as roll fronts in multiple stacked sands within the Goliad formation just as it does at the Alta Mesa uranium project;
• Historical drilling completed by Chevron Minerals during the late 1970s discovered multiple uranium roll fronts located at various depths within multiple sand units interpreted to be the lower C, middle C, B and A sands, all of which have been, or are currently productive, at the Alta Mesa uranium project;
• Additional exploration will be required to fully explore and delineate uranium mineralization on Tacubaya;
• Projected continuation of productive roll fronts from Alta Mesa wellfields 1, 3, 4 and 5B, and the currently operating wellfield 7;
• Initial exploration to include a 200-hole drilling program beginning in two key areas utilizing several rigs. Two rigs will begin in October, 2025, with an additional two drill rigs being added as the program progresses.

About the Alta Mesa ISR uranium CPP and wellfield

The Alta Mesa uranium project hosts a fully licensed and operational ISR central processing plant and operational wellfield located on 200,000-plus 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 pounds uranium per year with additional drying capacity of 500,000 pounds. The Alta Mesa uranium project operates under a 70/30 joint venture with Boss Energy Ltd., which is managed by the company.

The Alta Mesa uranium project utilizes 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 extraction to steadily increase from the wellfield as expansion continues through 2025 and beyond. The Alta Mesa CPP historically produced nearly five million pounds of uranium between 2005 and 2013 when production was curtailed as a result of low prices.
