EAGLE PLAINS' PARTNER REFINED ENERGY CORP. MOBILIZES GEOPHYSICAL TEAM TO THE DUFFERIN WEST PROJECT, SASKATCHEW

Eagle Plains Resources Ltd. partner Refined Energy Corp. has mobilized a ground geophysical crew to Eagle Plains' 100-per-cent-owned Dufferin West property in Saskatchewan.

Refined holds the exclusive option to acquire up to a 75-per-cent interest in the 10,140-hectare Dufferin project, which is made up of the North and West Dufferin properties, located adjacent to NexGen Energy's SW3 property and approximately 18 kilometres from Cameco's Centennial deposit, where historic drill hole VR-031W3 intersected 8.78 per cent U3O8 (triuranium octoxide) over 33.9 metres (SMAF 74G12-0061).

Results from the time-domain electroamgnetic (TEM) ground geophysical program will be used to generate detailed inversion models and develop three-dimensional Maxwell plates to further refine drill hole targeting in advance of a 2026 diamond drilling program. The drilling is planned to commence in late February and will include a minimum of three drill holes totalling approximately 1,200 metres, designed to test two distinct conductors on the Dufferin West property. The depth to the base of the sandstone unconformity is relatively shallow on the Dufferin West, interpreted to be between 60 and 340 metres. Concurrent with the drilling, a ground gravity geophysical program will be conducted to further define and refine drill targets.

The approved 2026 budget is approximately $1.7-million, subject to adjustments based on timing, progress and continuing results. The program is structured to allow for expansion as drilling advances and new targets are generated. The work will be managed by TerraLogic Exploration Inc.

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 (Saskatchewan Mineral Deposit Index) descriptions and assessment reports (Saskatchewan mineral assessment files) filed with the Saskatchewan government. Management cautions that historical results were collected and reported by past operators and have not been verified or confirmed by a qualified person but form a basis for continuing work on the subject properties. Eagle Plains' 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.

Dufferin option agreement details

To exercise the option, Refined must make a series of cash payments and share issuances to Eagle Plains and finance exploration expenditures on the project. These payments, share issuance and expenditures are separated into two phases, with the first option entitling the company to acquire a 60-per-cent interest in the project by paying $275,000, issuing an aggregate of one million postconsolidated common shares to Eagle Plains and financing $2.6-million in exploration expenditures on the project by Dec. 31, 2026. Pursuant to the second phase of the option, the company may acquire an additional 15-per-cent interest in the project (for a 75-per-cent total interest) by paying an additional $500,000, issuing an additional 500,000 postconsolidated shares to Eagle Plains and financing an additional $3-million in exploration expenditures on the project by Dec. 31, 2028. The Dufferin project is owned 100 per cent by Eagle Plains, which has been appointed as operator during the first option period.

If the first option or the second option is exercised, a 2-per-cent smelter returns royalty will be granted to Eagle Plains, 1 per cent of which may be repurchased for $2-million.

About Eagle Plains Resources Ltd.

Based in Cranbrook, B.C., Eagle Plains is a well-financed, 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 Venture Exchange (and the only one of these four that has not seen a rollback or restructuring of its shares). Eagle Plains has continued to deliver shareholder value over the years and through numerous spinouts has transferred over $110-million in value directly to its shareholders, with Copper Canyon Resources and Taiga Gold Corp. being notable examples. Eagle Plains latest spinout, Eagle Royalties Ltd., was listed on May 24, 2023, and, on Oct. 30, 2025, Eagle Royalties 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-V with a market capitalization of over $100-million.

On Oct. 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. 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 its diverse portfolio of projects toward discovery through collaborative partnerships and development of a highly experienced technical team.

Expenditures from 2010 to 2024 on Eagle Plains-related projects exceed $41-million, the majority of which was financed by third party partners. This exploration work resulted in approximately 50,000 metres of diamond drilling and extensive ground-based exploration work facilitating the advancement of numerous projects at various stages of development.

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

We seek Safe Harbor.
