Eagle Plains and Xcite define geophysical trends at Black Bay, Lorado, Gulch uranium projects

Eagle Plains and Xcite Define Prospective Geophysical Trends at Black Bay, Lorado and Gulch Uranium Projects, SK.

CRANBROOK, BC / ACCESS Newswire / June 11, 2026 / Eagle Plains Resources Ltd. (TSX-V:EPL)(OTCQB:EGPLF) ("EPL" or "Eagle Plains") with partner, Xcite Uranium Inc. (TSX-V:XRI) ("XRI or Xcite"), is pleased to announce initial geophysical results from a 2025 VTEM Plus airborne geophysical survey carried out by Geotech Airborne Geophysical Surveys that covered the Black Bay (1114ha), Lorado (643ha) and Gulch (1996ha) uranium projects. Advanced geophysical interpretation and modeling by Condor Consulting Inc. is nearing completion and will aid in prioritizing areas for summer fieldwork and targeting drill holes in Q3/Q4 2026.

At the Gulch Project, the regional Black Bay Fault, one of the main controlling structures for uranium mineralization in the Beaverlodge camp, is clearly defined along a break between anomalous high conductivity to the east and low conductivity to the west (Figure 1). The Calculated Vertical Gradient (CVG) of the magnetic data defines the Black Fault as an area with a high magnetic trend with offsets and splays possibly indicative of a favorable structural environment (Figure 2). A similar correlation is shown at the Lorado Project, with the Lorado Mine - Pitchie trend occurring along a coincident conductivity and magnetic high. Uranium mineralization at the Black Bay project occurs along the flanks of a pronounced magnetic high.

The 2025 VTEM Plus airborne geophysical survey covered the six uranium projects and the survey data was merged with publicly available geophysical data collected by previous operators.

The Black Bay, Lorado and Gulch uranium projects are located near Uranium City, Saskatchewan, and host near surface uranium mineralization as well as past producing uranium mines. In December 2023 Eagle Plains granted Xcite the exclusive right to earn up to an 80% interest in the Gulch, Lorado, Beaver River, Black Bay, Don Lake, and Smitty projects (see Dec 14 news release). The six projects comprising the Xcite option agreements cover 54 Saskatchewan Mineral Deposit Index (SMDI) occurrences and five past-producing uranium mines, and are 100% owned by Eagle Plains. The projects are prospective for Beaverlodge style, basement hosted and unconformity hosted uranium mineralization.

Project Highlights

Black Bay

• Seven SMDI mineral occurrences

• Host to the past producing Black Bay Uranium Mine

• Grab samples from historical drill core at 12.8m depth returned 16.74% and 9.64% U3O8

Lorado

• Three SMDI uranium occurrences

• Host to the past producing Lorado Uranium Mine

• Drilling at Pitche Zone returned 0.79% U3O8 over 1.88m

• Structurally controlled uranium mineralization associated with graphite and pyrite

Gulch

• Four SMDI uranium occurrences

• Host to the past producing Gulch Uranium Mine

• Uranium mineralization is associated with regional Black Bay structure

• Trenching returned up to 0.37% U3O8 over 3m

• Prospective for both polymetallic Beaverlodge-type and unconformity-related uranium mineralization

The Uranium City projects are included in a formal Exploration Agreement between Eagle Plains and the Ya'thi Néné Lands and Resource Office ("YNLR"), representing the Athabasca Denesułiné First Nations of Hatchet Lake, Black Lake, and Fond du Lac, the Northern Hamlet of Stony Rapids, and the Northern Settlements of Uranium City, Wollaston Lake and Camsell Portage.

Rock grab samples are selective samples by nature and as such are not necessarily representative of the mineralization hosted across the property. The above results were taken directly from the SMDI descriptions and assessment reports) filed with the Saskatchewan government. Management cautions that historical results were collected and reported by past operators and have not been verified nor confirmed by a Qualified Person, but form a basis for ongoing work on the subject properties. Management cautions that past results or discoveries on proximate land are not necessarily indicative of the results that may be achieved on the subject properties.

About the Beaverlodge Uranium District

The Beaver River, Black Bay, Don Lake, Gulch, Lorado, and Smitty projects are located in the Beaverlodge District near Uranium City in the Lake Athabasca region of Saskatchewan. Occurrences of uranium mineralization are abundant in the Uranium City area and have been explored and documented since the 1940s. The Beaverlodge camp was the first uranium producer in Canada, with historic production of approximately 70.25 million pounds of U3O8 between 1950-1982, from ore grades averaging 0.23% U3O8. The two largest producers were the Eldorado Beaverlodge (Ace-Fay-Verna) mine and the Gunnar uranium mine. The Beaverlodge area has seen limited uranium focused exploration since the early 1990's.

The Uranium City area projects have potential for both Beaverlodge-style and basement-hosted uranium mineralization. Key features about the projects include:

• Outcropping, largely northeast-southwest-trending tectonic fabric;

• Electromagnetic conductors that have been confirmed as graphite-rich pelites within or near major faults;

• Anomalous uranium geochemistry and radioactivity associated with graphitic faults;

• Compelling property-wide evidence for hydrothermal alteration;

• Uranium mineralization with corresponding elevations in pathfinder elements.

These factors, along with the presence of a substantial uranium endowment in both basement rocks and Athabasca basin cover rocks, indicate excellent potential for economic uranium mineralization within the project. The mineralization, structures and alteration identified on the claims to date are strong indicators of the possibility of a nearby source for the uranium mineralization.

Uranium City Option Agreement

Under the terms of the agreements, Xcite may earn an 80% interest in each of the Beaver River, Black Bay, Don Lake, Gulch, Lorado, and Smitty projects by completing CDN$3,200,000 in exploration expenditures, issuing 750,000 common shares of Xcite and making cash payments to Eagle Plains of CDN$55,000 over four years, for an aggregate of CDN$19,200,000 in exploration expenditures, 4,500,000 shares and $330,000 in cash to Eagle Plains. Upon Xcite fulfilling the terms of any or all of the earn-in agreements, an 80/20 joint venture will be formed, with Eagle Plains retaining a carried interest in all expenditures until delivery by Xcite or its assigns of a bankable feasibility study. During the option earn in period, XRI will be appointed as operator, and EPL will manage the exploration programs under the direction of a joint technical committee. The projects are owned 100% by EPL, who will retain an underlying 2% NSR royalty on the each of the properties.
