CRANBROOK, BC / ACCESS Newswire / July 23, 2026 / Eagle Plains Resources Ltd. (TSX-V:EPL)(OTCQB:EGPLF) ("EPL" or "Eagle Plains") is pleased to announce that partner Sun Summit Minerals Corp. (TSX-V:SMN)(OTCQB:SMREF) ("Sun Summit") has mobilized exploration crews to commence the second phase of 2026 fieldwork at Eagle Plains' Theory copper-gold project (the "Theory Project"), north-central British Columbia. The property is owned
The Theory Project borders Thesis Gold's Ranch Project to the north and is located within 10 km to the northwest of Sun Summit's JD Project. Sun Summit signed an option agreement with Eagle Plains to earn up to a
Theory Project 2026 Exploration Program
The 2026 work program will build on the success from the 2025 field season, the first significant fieldwork on the property in over 30 years. (see press release dated January 21, 2026)
The three phase 2026 fieldwork will include an Airborne MT geophysical survey (complete), a 28-day field program (underway) including prospecting, geological mapping, and geochemical sampling, and Induced Polarization (IP) geophysics on select targets.
A total of 476 line-kilometers of airborne magnetotelluric ("MobileMT") surveying was completed in June at a nominal line spacing of 250 meters. The data will image subsurface resistivity and help locate causative intrusions and possible conduits for mineralization. The Mobile MT survey was completed by Expert Geophysics Surveys Inc. of Newmarket, ON, under the guidance of geophysicist, Andrei Bagrianski, P.Geo. Final deliverables are anticipated to be received in the near term and will help to guide the second and third phases of fieldwork.
Phase 2 fieldwork will include mapping/prospecting and rock, soil, silt geochemical sampling with crews based out of temporary, helicopter supported, camps. Work will focus on the detailed evaluation of targets identified by 2025 fieldwork, assessment of areas of interest generated by the MobileMT survey, and ongoing target generation and assessment in underexplored areas of the property.
Phase 3 will include up to 22-line km of IP surveys over high priority target areas, including the Bev and Saboteur Zones.
The results from the 2026 work program will be analysed and modelled to identify and prioritize targets for 2027 drill testing. The proposed work program has a budget of approximately
Fieldwork will be managed by TerraLogic Exploration Inc. with helicopter and logistical support from the Sun Summit's JD Camp as required. The field work has commenced and is expected to continue into September. Eagle Plains is the project operator.
Highlights from 2025 Field Program
2025 work included:
Data Compilation with rectification and analysis of historical surface sampling and reconnaissance mapping.
Remote Sensing Acquisition of district-and property-scale datasets, focusing on VNIR and SWIR bands to identify mineral groups diagnostic of epithermal and porphyry alteration.
Field Program consisting of prospecting, detailed geological mapping, and systematic rock, soil, and silt geochemical sampling on targets identified through data analyses.
Saboteur Zone: New high grade copper discovery
3km length zone of copper mineralization associated with coincident magnetic high transition zone and strong radiometric potassic alteration anomaly
15 of the rock samples collected returned over

0.65% copper, 12.6 g/t gold, 3150 g/t silver;
Petrographic analyses of 2025 samples identified strong epidote-chlorite-carbonate alteration directly with hypogene copper mineralization (chalcopyrite - bornite - chalcocite). This type of mineralization and alteration assemblage is interpreted to represent the inner shell of a porphyry system, which may indicate a proximal source for some of the Theory mineralization.

The 9676ha Theory Project is located in northern BC within the Toodoggone Mining District. The district is endowed with both epithermal gold and porphyry copper-gold deposits, most notably the past producing Kemess Mine owned by Centerra Gold. The Omineca Resource Road provides access to the region from Mackenzie, BC. Recent road upgrades completed in 2023 by Thesis Gold on their Lawyers-Ranch Project brought road access to within 8 kms of the Theory Project.
Geology in the Theory region is primarily comprised of lower Jurassic Hazelton Group volcanics which unconformably overlie late Triassic Takla Group volcanics. The entire package of rocks is intruded by late Triassic and early Jurassic stocks. The majority of the Theory property encompasses the highly prospective Jurassic-Triassic unconformity (~200 Ma), termed by the BC Geologic Survey as the 'Red-Line', which is known to have a high spatial correlation to many of the known deposits throughout the Golden Triangle and Toodoggone.
Exploration by previous operators has been intermittent since the mid-1960's and regional government surveys are sparse, however encouraging mineralization and alteration commonly associated with both epithermal and porphyry systems has been documented. The most significant documented work was completed in 1988 in the north and west areas of the Theory project area. Work consisted primarily of alpine ridge and subalpine prospecting traverses as well as reconnaissance soil sample lines in areas where no outcrop was present. This work documented occurrences of low-sulphidation epithermal-related mineralization including quartz-barite veins with up to 8.2 g/t Au, 195 g/t Ag, and
Recent exploration success in the area has been highlighted by Thesis Gold's announcement at their Lawyers-Ranch Project of a combined Measured and Indicated Mineral Resource of 4.564 Moz grading 1.21 g/t AuEq and Inferred Resources of 643 koz grading 1.23 g/t AuEq (Lawyers - Ranch Project NI 43 - 101 Technical Report and Pre - feasibility Study British Columbia, Canada Effective Date: December 1, 2025) and by Amarc Resources' new high-grade copper-gold-silver discovery at the AuRORA zone of the Joy Project (Amarc Resources, January 17, 2025 News Release).
In late 2023 Eagle Plains acquired the property through staking and third-party agreements. After undertaking initial compilation and interpretation of historical data on the project, Eagle Plains completed a property wide, high resolution airborne magnetic and radiometric survey in July 2024, followed by fieldwork in 2025.
