Sun Summit concludes 2025 exploration program at Theory Project, British Columbia

Sun Summit Minerals Corp. [TSXV: SMN; OTCQB: SMREF] has completed the 2025 exploration program at the Theory project in the Toodoggone mining district, north-central British Columbia.

The Theory project borders Thesis Gold’s Ranch project to the north and is located 10 km northwest of Sun Summit’s JD project. Sun Summit has an exclusive option agreement with Eagle Plains to earn up to a 100% interest in the project, located in the highly prospective Toodoggone mining district.

Highlights: Preliminary mapping of alteration assemblages at the Bev area strongly suggests potential for a concealed porphyry system: At upper elevations, widespread epidote-carbonate-plus-or-minus-chlorite-plus-or-minus-hematite alteration is commonly associated with copper mineralization as chalcopyrite, bornite or chalcocite in epidote-carbonate-quartz veining/fractures.

The saboteur zone, located northeast of the main Bev showing, represents a new target generated in 2025: Prospecting and mapping identified an approximately 3-km-long zone of local chalcopyrite, bornite and chalcocite mineralization associated with a northeast-trending magnetic high.

Prospecting at the Fred-DM area focused on an approximately 5-km linear magnetic-low trend associated with the known mineral occurrences: Mineralized veins and fractures are spatially associated with north-northeast-trending barite veins, with over 150 metres of continuous barite vein exposure that is up to four metres thick, and subcrop/float exposures that suggest strike length of copper mineralization in excess of 1.0 km.

Fieldwork at the Stik-1 showing identified epithermal-related alteration and mineralization within a proximal to a granodioritic-to-dioritic intrusion.

A total of 268 rock grab samples, 417 soil samples and 40 silt samples were collected: Geochemical and assay results are pending and will be reported after receipt and interpretation.

“We are very pleased with the early prospecting work completed on the Theory project, and the potential for discovery of a large porphyry system,” said Niel Marotta, CEO of Sun Summit Minerals. “The Theory project is nearly 10,000 hectares, complementing the roughly 15,000 hectares at our JD project, and represents an important asset base in the Toodoggone region. The 2025 prospecting program will help define drill targets for upcoming exploration seasons, and we look forward to continuing to work with Eagle Plains as we advance the Theory project towards its inaugural drill campaign.”

The 2025 exploration goals at the Theory project were to identify and assess new areas of interest and to refine drill targets generated through integrating historical exploration data with new geophysical and geochemical surveys. Eagle Plains and Sun Summit commissioned Terralogic Exploration Inc. of Cranbrook, B.C., to design and execute the 2025 satellite (remote sensing) data acquisition and field programs.

The 2025 work included: data compilation with rectification and analysis of historical surface sampling and reconnaissance mapping; acquisition of district- and property-scale remote-sensing data sets, focusing on VNIR (visible and near-infrared) and SWIR (short-wave infrared) bands to identify mineral groups diagnostic of epithermal and porphyry alteration.

A field program consisting of prospecting, detailed geological mapping, and systematic rock, soil and silt geochemical sampling on targets identified through data analyses was conducted.

This integrated approach builds on the 2024 airborne magnetic and radiometric survey results and was designed to prioritize high-potential areas for future drilling. More than 15 distinct geochemical and geophysical targets were defined for field follow-up.

Terralogic Exploration engaged the services of EarthDaily Analytics to interpret remote-sensing data sets. A total of 257 rock samples, 417 soil samples and 27 silt samples were collected during the program, which was based out of fly camps, with Sun Summit’s JD camp used as a logistical hub.

Terralogic field personnel carried out geological mapping, prospecting and geochemical sampling at all of the primary target areas. Most targets are underlain by mafic volcanic sequences of the Takla group, with Jurassic Hazelton group intermediate and mafic volcanics and related sediments encountered at the Stik, Dar and southernmost Bev areas. Intrusions encountered in outcrop are noted at the Stik-1 showing, with granodiorite boulders also noted south of the Bev zone.

Sun Summit is engaging with first nations on whose territory the company’s projects are located and is discussing their interests and identifying contract and work opportunities as well as opportunities to support community initiatives.

The Omineca resource road provides access to the region from Mackenzie, B.C. Recent road upgrades completed in 2023 by Thesis Gold on its Lawyers-Ranch project brought road access to within 8 km of the Theory project.

The project is 450 km northwest of the city of Prince George and 25 km north of the Sturdee airstrip. It is proximal to existing infrastructure in place to support the past-producing Kemess mine, including roads and a hydroelectric power line.

The JD project is in a favourable geological environment characterized by both high-grade epithermal gold and silver mineralization as well as porphyry-related copper and gold mineralization.
