Eagle Plains Partner Refined Energy Completes First Drill Hole at Dufferin West; Second Hole Underway to Test High-Priority EM Conductor

CRANBROOK, BC / ACCESS Newswire / March 17, 2026 / Eagle Plains Resources Ltd. (TSXV:EPL)(OTCQB:EGPLF) (“EPL” or “Eagle Plains”) is pleased to announce that partner Refined Energy Corp (CSE: RUU; OTC: RFMCF; FRA: CWA0) (“Refined”) has completed the first drill hole at Eagle Plains’ 100% owned Dufferin West Property, Saskatchewan.

Refined holds the exclusive option to acquire up to a 75% interest in the 10,140ha Dufferin Project, which is made up of the North and West Dufferin properties, located adjacent to NexGen Energy’s SW3 Property and approximately 18km from Cameco’s Centennial Deposit where historic drill hole VR-031W3 intersected 8.78% U308 over 33.9m (SMAF 74G12-0061).

Highlights

• Maiden drill hole (DW26-001) successfully reached targeted unconformity depth at 332 metres, validating the Company’s geological model;

• Second drill hole (DW26-002) now underway testing the same high-priority EM conductor and associated structural target;

• Ground gravity survey completed to further refine drill targets

• Initial drill program planned for a minimum of three holes totaling approximately 1,200 metres

Drill hole DW26-001 intersected the unconformity at a depth of 332 metres and was completed in basement rock at 432 metres. Core logging and sampling are underway, with samples to be submitted to an accredited laboratory for detailed analysis and assay results.

MWH Geo-Surveys recently completed a ground gravity survey across the target area. A total of 817 unique stations in a 50m by 100m grid were surveyed covering approximately 530ha. Preliminary results have been incorporated into the targeting of the second drill hole and will be further utilized for targeting the planned third drill hole.

The second drill hole, DW26-002, is now underway, located approximately 100 metres south of the first hole. The hole is designed to further evaluate the same electromagnetic (“EM”) conductor defined by previous airborne VTEM data and refined by a recently completed time-domain moving loop EM (TEM) ground geophysical program.

The second hole is also designed to test the interpreted intersection of the EM conductor with a gravity low, believed to represent a cross-cutting N70 structural fault – a structural setting commonly associated with Athabasca Basin uranium mineralization.

The current drill program is designed to test multiple high-priority geophysical and structural targets and is planned to consist of a minimum of three drill holes totalling approximately 1,200 metres, with oriented core collection to provide critical geological and structural information. The initial budget is approximately $1.7 million.

The Dufferin Project is located on or in close proximity to the known trace of the Virgin River Shear Zone and related splays which are key structures for potential uranium mineralization.

The Project is prospective for unconformity- and basement-hosted uranium mineralization in proximity to the Virgin River Shear Zone. Faulted basement contacts and brittlely reactivated structures are the primary locations for mineralization in the area covered by the Dufferin Project. The relatively high concentration of secondary uranium-bearing minerals demonstrated by prior exploration work on the Dufferin Project may also indicate uranium mineralization remobilization may play an important role in this region of the Athabasca Basin. Geophysical EM and magnetic anomalies demonstrated by prior exploration work on the Dufferin Project are supported by previous uranium and boron soil and lake sediment anomalies along the inferred fault zones, which are expected to aid in focusing future exploration programs.

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.

About Eagle Plains Resources

Based in Cranbrook, B.C., Eagle Plains is a well-funded, prolific project generator that continues to conduct research, acquire and explore mineral projects throughout western Canada, with a focus on critical metals integral to an increasingly electrified, decarbonized economy.

The Company was formed in 1992 and is the fourth-oldest listed issuer on the TSX-V (and the only one of these four that has not seen a roll-back or restructuring of its shares). Eagle Plains has continued to deliver shareholder value over the years and through numerous spin outs has transferred over $110,000,000 in value directly to its shareholders, with Copper Canyon Resources and Taiga Gold Corp. being notable examples. Eagle Plains latest spinout, Eagle Royalties Ltd. (CSE:”ER”) was listed on May 24, 2023, and on October 30, 2025, ER shareholders overwhelmingly approved a three-cornered amalgamation that resulted in a reverse takeover of Eagle Royalties by Summit Royalty Corp. The resulting issuer is named Summit Royalties Ltd. and trades under the symbol SUM on the TSX Venture Exchange with a market capitalization of over $100M.

On October 2, 2024, Eagle Plains announced the formation of a separate division within the Company that will give Eagle Plains’ shareholders direct exposure to strategic opportunities in Canadian green energy transition. As a wholly owned subsidiary of Eagle Plains, Osprey Power Inc. (“OP”) will focus on identifying and advancing innovative and diverse clean energy project portfolios in target markets throughout Canada, with an initial focus on Western Canada.

Eagle Plains’ core business is acquiring grassroots critical- and precious-metal exploration properties. The Company is committed to steadily enhancing shareholder value by advancing our diverse portfolio of projects toward discovery through collaborative partnerships and development of a highly experienced technical team.

Expenditures from 2010-2025 on Eagle Plains-related projects exceed $41M, the majority of which was funded by third-party partners. This exploration work resulted in approximately 50,000m of diamond-drilling and extensive ground-based exploration work facilitating the advancement of numerous projects at various stages of development.

Throughout the exploration process, our mission is to help maintain prosperous communities by exploring for and discovering resource opportunities while building lasting relationships through honest and respectful business practices.

On behalf of the Board of Directors of Eagle Plains
