Sun Summit Minerals Corp. (TSXV: SMN) (OTCQB: SMREF) ("Sun Summit" or the "Company") is pleased to announce that, further to its news release of January 13, 2025, the Company has entered into an option agreement with Eagle Plains Resources Ltd. (TSXV: EPL) ("Eagle Plains") (the "Theory Option Agreement") to earn up to a 100% interest in 10,000 hectares of mineral claims in the highly prospective Toodoggone Mining District, British Columbia (the "Theory Project").

Highlights

• Strategic acquisition: The acquisition of the Theory Project will increase Sun Summit's Toodoggone footprint by ~10,000 hectares, creating a combined district-scale project of ~25,000 hectares.

• Increased land position in prime location: The Theory Project borders Thesis Gold's Ranch Project to the north and is located within 10 km of Sun Summit's JD Project, presenting significant synergies and logistical advantages. The combined land package would effectively border the Ranch Project on its northern and eastern boundary and provide the Company with an attractive, district scale exploration and development opportunity.

• Significant exploration potential: Theory Project hosts highly prospective geology with both epithermal-related gold targets, and large bulk-mineable porphyry-related copper-gold targets, supported by historical exploration and recent geophysical surveys.

• Attractive option terms: The Theory Option Agreement includes the option to acquire a 75% interest over four years with aggregate exploration expenditures of CDN $3,000,000, cash payments of CDN $250,000, and the issuance of 750,000 shares, with the remaining 25% interest available for CDN $1,000,000.

• Ongoing exploration planning: Sun Summit in cooperation with Eagle Plains will complete an extensive data compilation and target generation exercise, which will inform future exploration planning at the Theory Project.

Niel Marotta, CEO of Sun Summit, commented: "We are pleased to finalize the Theory Option Agreement. This enlarged district scale Copper-gold project represents an exciting opportunity to revive exploration in the northern part of the Toodoggone mining district. We wish to thank Eagle Plains for having the business acumen to acquire an extensive land package with regional exploration targets. This deal, combined with the JD property, adds to the potential for a significant discovery and significantly enhances our strategic position in the Toodoggone Mining District. By combining the Theory and JD Projects, we create a district-scale opportunity with exceptional exploration potential and significant logistical synergies. The option terms are both manageable and structured, allowing us to maintain financial flexibility while advancing exploration efforts. This acquisition aligns with our goal of building a robust, diversified portfolio in this highly active mining district, and we look forward to unlocking the full potential of these assets."

Theory Project

The Theory Project comprises 23 mineral claims covering 9,676 hectares. The project is 100% owned by Eagle Plains, with 122 hectares of the property subject to an underlying 0.5% net smelter returns royalty ("NSR") held by a third party. The project is located in north-central B.C. within the Toodoggone Mining District, and is in close proximity with Sun Summit's JD Project. The project area shares similar geology to the JD Project and Thesis Gold's Ranch-Lawyers Projects.

The project is helicopter-accessible and recent road upgrades completed in 2023 by Thesis Gold has brought road access to within 8 kilometres of the southern boundary of the Theory Project.

Geology in the Theory region is primarily comprised of lower Jurassic Hazelton Group volcanics (Toodoggone Formation, same host rock as the JD Project) which unconformably overlie late Triassic Takla Group volcanics. The entire package of volcanic and volcaniclastic rocks is intruded by late Triassic and early Jurassic stocks. The Jurassic-Triassic unconformity (~200 Ma), termed by the B.C. Geological Survey as the 'red-line', is observed throughout the Golden Triangle and Toodoggone regions to have a high spatial correlation to many known mineral deposits. The majority of the property encompasses this highly prospective contact.

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 to 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.

Note: Grab samples by nature are selective and therefore may not be representative of the mineralization being evaluated.

Eagle Plains completed a 2024 property-wide airborne magnetic and radiometric survey at a nominal 100 metre line spacing to advance the property. The airborne geophysical survey highlighted a 13 by 13 kilometre area underlain by highly prospective Takla Group volcanics to the east and north, and Hazelton Group volcanics and sediments to the south and west. This data provides a solid foundation upon which to integrate historical local mapping and sampling results.

Next Steps

The terms and conditions of the Theory Option Agreement are subject to the approval of the Exchange.

An extensive compilation of historical exploration data is underway with emphasis on the extensive prospecting, mapping and geochemical surveys completed in 1988. Detailed georeferencing of historical geochemical anomalies and geological structures of interest against the new 2024 geophysical dataset will assist with identification of follow-up field targets for the 2025 season.

Following the target identification exercise, an exploration plan and budget will be defined for the 2025 season. Minimum expenditures in 2025 are $200,000 with work expected to be conducted from the JD camp. The Company intends to secure a new mineral exploration permit for any future diamond drilling. The application process will be initiated by Sun Summit.

Theory Option Agreement Terms

Under the terms of the Theory Option Agreement, Sun Summit has the option to acquire a 75% interest in the Theory Project ("Option 1") over a 4-year period in exchange for the issuance of 750,000 common shares, the payment of $250,000 cash and incurring total exploration expenditures on the Theory Project of $3,000,000.

About the JD Project

The JD Project is located in the Toodoggone mining district in north-central British Columbia, a highly prospective deposit-rich mineral trend. The project covers an area of over 15,000 hectares and is in close proximity to active exploration and development projects, such as Thesis Gold's Lawyers and Ranch projects, TDG Gold's Baker-Shasta projects, Amarc Resource's AuRORA project, Centerra's Gold's Kemess East and Underground projects, as well as the past-producing Kemess open pit copper-gold mine.

The project is 450 kilometres northwest of the city of Prince George, and 25 kilometres 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. Some historical exploration, including drilling, geochemistry and geophysics, has been carried out on the property, however the project area is largely underexplored.
