Eagle Plains’ Partner Sun Summit Minerals Approves 2025 Exploration
Plan for the Theory Project, Toodoggone District, BC
Cranbrook, B.C., August 05 , 20 25: (TSX-V:EPL) (OTCQB: EG PLF) (“EPL” or
“Eagle Plains”) is pleased to announce that partner Sun Summit Minerals Corp. (TSX-
V: SMN; OTCQB: SMREF) (“Sun Summit”) has approved the 2025 exploration plan
at the Eagle Plains’ Theory copper -gold project (the " Theory Project "), Toodoggone
Mining District, north -central British Columbia . The property is owned 100% by Eagle
Plains, with 122 hectares of the property subject to an underlying 0.5% Net Smelter Royalty
held by a third party.
The Theory Project borders Thesis Gold’s Ranch Project to the north and is located within
10 km to the North West of Sun Summit’s JD Project. Sun Summit signed an option
agreement with Eagle Plains Resources Ltd. to earn up to a 100% interest in approximately
10,000 hectares of mineral claims in the highly prospective Toodoggone Mining District .
(see press release dated March 17, 2025)
Theory Project Exploration Program
The focus of the 2025 program will be to identify drill targets using prospecting, geological
mapping, geochemical sampling and remote sensing to follow up on areas of interest
generated through a 2024 airborne geophysical survey and a comprehensive, ongoing data
compilation. The proposed work program will have a budget adequate to exceed the
minimum required 2025 exploration expenditures of $200,000.
Eagle Plains will serve as operator for the project. The work will be completed TerraLogic
Exploration and is anticipated to begin in late August and continue into September.
See Theory Property Information and Map here
The 9676ha Theory Pr oject 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 6.2%
Cu at the DM occurrence (BC Minfile 094E 231)*; and a quartz carbonate vein system with
up to 6.8 g/t Au and 1,480 g/t Ag at the Fred-1 occurrence (BC Minfile 094E 402)*. The
BEV occurrences (BC Minfile 094E 259)*, interpreted as a Cu -Au porphyry target,
returned select historical rock results up to 0.47% Cu, 10.5 g/t Ag, and 0.13 g /t Au .
Detailed soils revealed a 1.6 by 2 kilometre copper-in-soil anomaly with peak soil results
to 920 ppm Cu . Very little work is documented in the south and eastern parts of the
property.
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 4.0 Moz and an Inferred Mineral Resource of 727 Koz at respective grades of 1.51 and
1.82 g/t AuEq. (Thesis Gold, May 1, 2024 News Release) 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.
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. 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.
