Eagle Plains’ Partner Refined Energy Corp. Approves 2026 Drill

Program for the Dufferin West Project, Saskatchewan

Cranbrook, B.C., December 18, 2025: Eagle Plains Resources Ltd. (TSX-V:EPL) (OTCQB:

EGPLF) (“EPL” or “Eagle Plains”) is pleased to announce that partner Refined Energy Corp (CSE:

RUU; OTC: RFMCF; FRA: CWA0) (“Refined” ) has approved a proposal for a 2026 exploration

program, which will include a minimum of 1200 meters of diamond drilling, 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).

The 2026 program is driven by results from geophysical and technical work, paired with advanced

interpretation to prioritize targets. The Phase I proposal includes ground-based gravity and electromagnetic

surveys and 3 drill holes totalling approximately 1200 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 to 340m. The approved budget is approximately $1.7

million, subject to adjustments based on timing, progress and ongoing 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. and is planned to commence in the first quarter of 2026.

Chuck Downie, P.Geo., President and CEO of Eagle Plains, commented, “We look forward to working

with Refined to undertake our first drill program on the Dufferin Project. We identified the Dufferin area

as a prospective area for claim acquisition starting in 2023, and the upcoming drilling is the culmination

of extensive technical work and data analyses, and affirms our project generator business model.”

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 veri fied nor confirmed by a Qualified Person, but form a

basis for ongoing 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 o n 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 fund exploration expenditures on the Project. These payments, share issuance and expenditures are

separated into two phases, with the first Option e ntitling the Company to acquire a 60% interest in the

Project by paying CA$275,000, issuing an aggregate of 1,000,000 post -consolidated common shares to

EPL and funding CA$2,600,000 in exploration expenditures on the Project by December 31, 2026.

Pursuant to the second phase of the Option, the Company may acquire an additional 15% interest in the

Project (for a 75% total interest) by paying an additional CA$500,000, issuing an additional 500,000 post-

consolidated Shares to EPL and funding an additional CA$3 ,000,000 in exploration expenditures on the

Project by December 31, 2028. The Dufferin project is owned 100% by EPL, wh ich has been appointed

as Operator during the first Option period.

If the First Option or the Second Option is exercised, a 2% smelter returns royalty will be granted to Eagle

Plains, 1% of which may be repurchased for CA$2,000,000.

Qualified Person

Technical information in this News Release has been reviewed and approved by C.C. Downie, P.Geo., a

director and officer of Eagle Plains, hereby identified as the “Qualified Person” under N.I. 43-101.

Pine Channel Option Agreement

Eagle Plains has received notice from Apogee Minerals Ltd (TSX -V-“APMI”) that Apogee has

decided not to proceed with the option on Eagle Plains’ 100% owned Pine Channel Au project, effective

as of December 17, 2025.

See Pine Channel Gold Project Information and Map here

The Pine Channel Property consists of 29 mineral dispositions covering 6,519 hectares located

approximately 40 km west of Stony Rapids, Saskatchewan which is the logistics/business hub for

northern Saskatchewan. The property can be accessed year -round by f loat- or ski-equipped aircraft

from Stony Rapids or Fort McMurray, AB. The eastern and northern part of the property is transected

by a high voltage powerline. Most geological fieldwork is limited to late May to October but other

operations such as geophysical surveys and diamond drilling can be completed year-round.

The main deposit type that is being explored for at Pine Channel is structurally controlled vein -quartz

(lode) gold deposits. Mineral occurrences on the Pine Channel Property contain predominantly gold,

with rare base metal occurrences. Within the Pine Cha nnel tenures there are twenty documented

historical showings.

Government mapping in the Pine Channel area dates from 1913, with the first industry work reported

in 1950. A total of 51 assessment reports have been filed within the current Pine Channel tenure area.

Past operators include Golden Rule Resources Ltd. and Colchis Resources Ltd. who were both active

on the project during the 1980’s, the last sustained period of exploration in the area. The most recent

work prior to Eagle Plains acquiring the claims in 2018 was in 2013 when the area was flown with an

airborne Variable Time Domain Electromagnetic (“VTEM”) survey focused on locating targets for

diamond exploration. There has been a total of 6,066 metres of diamond drilling in 115 historic holes

completed within the current Pine Channel property claim boundaries, with the majority of the holes

completed less than 100 metres in length. Although the wide -spaced drilling did intersect significant

gold mineralization in places, much of the drilling was completed using thin diameter core which is

considered ineffective for assessing the high -grade “nuggety” gold shears and veins found at Pine

Channel.

Since acquiring the property, Eagle Plains has completed field programs focused on prospecting and

mapping in areas of known mineral occurrences. The work confirmed the widespread occurrences of

auriferous quartz veins and associated shear systems in the Pine Channel property. Analytical results

from the seventy-two rock samples collected in 2020 range from 6 ppb Au to 68,400 ppb Au. Twenty-

three of the samples returned greater than 1 g/t Au, and eight returned greater than 10 g/t Au. The most

encouraging of the known showings are the ELA Shaft showing (SMDI 1574) and Occurrence No. 6

and No. 8 (SMDI 1581), which both demonstrate anomalous gold geochemical results and potential for

extension of known mineralization along strike.

2022 and 2024 work included a helicopter-borne high-resolution aeromagnetic and radiometric survey

and ahigh resolution LiDAR and orthophoto survey. Lineation analyses of the LiDAR imaging,

combined with the aeromagnetic data, defined a number of new target areas adjacent to and along strike

from known mineralization, which will be priority targets for future exploration.
