Eagle Plains Intersects Mineralization in Step-out Holes at George Lake Critical Metals Project, Saskatchewan

CRANBROOK, BRITISH COLUMBIA / ACCESS Newswire / March 4, 2026 / Eagle Plains Resources Ltd. (TSXV:EPL)(OTCQB:EGPLF) (“EPL” or “Eagle Plains”) is pleased to report that two of the three holes planned for the 2026 diamond drilling program have been completed at the George Lake Project, northeast Saskatchewan. Both of the holes successfully intersected the George Lake Zn/Pb deposit horizon, with the deepest 2026 intersection to date approximately 208m vertically below the deepest historical intercept. Analytical results are pending for both holes. Preliminary interpretation of the 2026 drilling, along with historical results, indicates that mineralization remains open down-dip and along strike.

The 2026 drill targeting is driven by results from geophysical and technical work, paired with advanced interpretation. The holes were located to test for down dip extensions of the prospective sedimentary exhalative (sedex) stratigraphy, over a strike length of 385m. The program was conducted by TerraLogic Exploration Inc. of Cranbrook, BC under the direction of Kerry Bates, P.Geo., Exploration Manager for Eagle Plains. The drill contractor was New Age Drilling Solutions.

The George Lake deposit horizon is characterized by significant critical metal mineralization over a broad strike length of approximately 8.1 kilometers. The source of this mineralization has never been established, and forms the basis for Eagle Plains’ continuing exploration work.

George Lake is one of the projects 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. YNLR has been providing technical support for the program.

The project is also eligible for the Saskatchewan Targeted Mineral Exploration Incentive (TMEI), which may provide funding of up to $150,000 towards drilling-related program costs.

2026 Drilling Summary

*Coordinates projected in NAD83 UTM Zone 13N

Drill-hole GL26001 was designed to undercut historic drillholes GL08-02: 55.8m (206.0-261.8m) @ 4.01% Zn/0.54%Pb including 8.0m (252.8-260.6m) @ 6.96% Zn/1.42% Pb) and GL-21: 32.0m (286.5-318.5m) @ 3.66% Zn/0.40% Pb including 10.7m (297.2-307.9m) @ 5.43% Zn/0.34% Pb). The intersected mineralized stratigraphy has a drill length of 56m from 480-536m. The mineralization is hosted in white/grey quartzite with disseminated and stringer sphalerite, and disseminated galena, pyrrhotite and arsenopyrite. The mineralized zone, as well as the hanging wall and footwall contacts have strong to moderate biotite and silica alteration. The mineralized horizon was intersected approximately 208m downdip from GL-21, the closest hole on the section and one of the deepest holes historically drilled at the deposit.

Drill-hole GL26002, an 200m step-out to the southwest of GL26001, undercut historic drillholes GL08-01: 57.90m (189.2-247.1m) @ 2.69% Zn/0.41% Pb including 6.0m (220.1-226.1m) @ 5.37% Zn/0.64% Pb) and GL-25: 42.7m (237.7-280.4m) @ 3.09% Zn/0.36% Pb including 10.7m (239.3-250.0) @ 5.38% Zn /0.81% Pb). The mineralized zone has a length of 49m from 468-517m, with disseminated and stringer sphalerite associated with galena, pyrrhotite and arsenopyrite. The clean white/grey quartzite host has strong pervasive silicification. The mineralized horizon was intersected approximately 171m downdip from GL-25, the closest hole on the section and one of the deepest holes historically drilled at the deposit.

The current drill-hole, GL26003, is a 185m step-out to the northeast of GL26001, designed to undercut historic drillholes GL08-08B and GL08-03 (40.0m (221.5-261.5m) @ 1.80% Zn/0.23% Pb including 7.00m (252.5-259.5m) @ 5.23% Zn/1.00% Pb).

Detailed reporting will be completed when all geochemical results have been received and interpreted.

All drill indicated intercepts as reported in this news release are measured along core length and true thickness is yet to be determined.

About the George Lake Project

The fully permitted 6868 ha George Lake project is located 280km north of La Ronge, Saskatchewan. The project has excellent access and is located on a recently completed highway connecting Saskatchewan Highway 905 to the community of Wollaston Lake. Eagle Plains holds a 100% interest in claims comprising the property, subject to a 2% royalty held in favour of Summit Royalties Ltd., 1% of which can be bought back by Eagle Plains for $1,000,000.

George Lake Project Highlights

• 4,131m of historical drilling completed in 22 holes at the deposit, with the best drill holes returning 57.9m grading 2.65% Zn and 0.41% Pb (including 13.5m grading 4.36% Zn and 0.76% Pb) (DDH GL08-01) and 47.8m grading 4.03% Zn and 0.44% Pb (including 8.0m grading 6.96% Zn and 01.42% Pb) (DDH GL08-02) (SMAF 64E05 0033);

• George Lake Deposit comes to surface and has dimensions of approximately 35m width x 800m length, and is open to depth and along strike;

• Potential for discovery of extensions of existing mineralization and other discrete mineralization elsewhere on the property;

The property overlies 13 Saskatchewan Mineral Deposit Index (“SMDI”) occurrences including the George Lake Zn Deposit. Zinc and lead mineralized boulders were discovered in the George Lake area in 1965 which led Falconbridge Nickel Mines to acquire a large land position in the area, resulting in a 34-hole diamond drill program in 1969-70 which defined the George Lake deposit. The deposit contains sedimentary-exhalative (“sedex”) style mineralization, with a higher-grade core of >5% Zn.

Some of the above results were taken directly from the SMDI descriptions and assessment reports (SMAF) 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. All drill indicated intercepts as reported in this news release are measured along core length and true thickness is yet to be determined.
