SUN SUMMIT SIGNS LETTER OF INTENT TO ACQUIRE THE THEORY PROJECT IN THE TOODOGGONE MINING DISTRICT, B.C.

Sun Summit Minerals Corp. has entered into a non-binding letter of intent (LOI) with Eagle Plains Resources Ltd. whereby Sun Summit and Eagle Plains will negotiate and settle the terms of a definitive option agreement for Sun Summit to acquire up to a 100-per-cent interest in Eagle Plains' wholly owned Theory copper-gold project located in the highly prospective Toodoggone mining district, British Columbia.

Highlights

• Strategic acquisition: Proposed acquisition of the Theory project would increase Sun Summit's Toodoggone footprint by approximately 10,000 hectares, creating a combined district-scale project of approximately 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 kilometres of Sun Summit's JD project, presenting significant synergies and logistical advantages. The combined land package would effectively border the Ranch property 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 high-grade 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 letter of intent includes the option to acquire a 75-per-cent interest over four years with exploration expenditures of $3-million, cash payments of $250,000, and issuance of 750,000 shares, with the remaining 25-per-cent interest available for $1-million.
• Continuing exploration planning: Once the formal agreement is finalized and executed, Sun Summit will complete an extensive data compilation and target generation exercise, which will inform future exploration planning at Theory.

Sharyn Alexander, president of Sun Summit, commented: "This proposed acquisition of the Theory project 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-per-cent owned by Eagle Plains, with 122 hectares of the property subject to an underlying 0.5-per-cent net smelter royalty (NSR) held by a third party. The project is located in north-central British Columbia 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 eight kilometres of the southern boundary of the Theory project.

Geology in the Theory region primarily comprises 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 (approximately 200 Ma (million years ago)), 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-1960s 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 grams per tonne Au (gold), 195 g/t Ag (silver) and 6.2 per cent Cu (copper) at the DM occurrence (B.C. 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 (B.C. Minfile 094E 402). The BEV occurrences (B.C. Minfile 094E 259), interpreted as a Cu-Au porphyry target, returned select historical rock results up to 0.47 per cent Cu, 10.5 g/t Ag and 0.13 g/t Au. Detailed soils revealed a 1.6-by-two-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. These data provides a solid foundation upon which to integrate historical local mapping and sampling results.

Letter of intent terms

Under the terms of the agreement, Sun Summit would acquire a 75-per-cent interest in the Theory project over a four-year period in exchange for the issuance of 750,000 common shares, $250,000 cash and exploration expenditures to a total of $3-million; according to the following schedule:

• $200,000 ($200,000 total) on or before Dec. 31, 2025;
• $400,000 ($600,000 total) on or before Dec. 31, 2026;
• $1-million ($1.6-million total) on or before Dec. 31, 2027, including a minimum of 1,000 metres of drilling;
• $1.4-million ($3-million total) on or before Dec. 31, 2028, including a minimum of 1,500 metres of drilling.

In addition, Sun Summit will agree to pay a total cash consideration of $250,000 according to the following schedule:

• $20,000 cash payment on signing of formal option agreement;
• $30,000 ($50,000 total) on or before Dec. 31, 2025;
• $50,000 ($100,000 total) on or before Dec. 31, 2026;
• $75,000 ($175,000 total) on or before Dec. 31, 2027;
• $75,000 ($250,000 total) on or before Dec. 31, 2028.

In addition, Sun Summit will agree to issue to Eagle Plains 750,000 voting class common shares according to the following schedule:

• 50,000 shares on signing of formal option agreement;
• 100,000 shares (150,000 total) on or before Dec. 31, 2025;
• 150,000 shares 300,000 total) on or before Dec. 31, 2026;
• 200,000 shares (500,000 total) on or before Dec. 31, 2027;
• 250,000 shares (750,000 total) on or before Dec. 31, 2028.

Upon completion and notice of exercise of option 1, Eagle Plains will retain a total 2.0-per-cent NSR on all areas underlain by the project, which may be bought down to 1.0 per cent through a cash payment of $1-million. Two of the claims are subject to a separate agreement which includes a 0.5-per-cent net smelter returns royalty payable by the optionor to an arm's-length third party, which may be repurchased in its entirety for $1-million. For greater clarity, none of the Theory claims are encumbered in excess of an aggregate of 2.5-per-cent NSR.

Following the completion and notice of exercise of option 1, Sun Summit shall have the right to earn an additional 25-per-cent (for a total of 100 per cent) by making an additional cash payment and issuing shares (option 2). In order to exercise option 2, Sun Summit shall notify Eagle Plains of its intent to increase its interest to 100 per cent, no later than 180 days from the notice of exercise of option 1 and make additional one-time payments of $1-million cash; of which half can be paid in Sun Summit shares (valuation to be at the time of notification).

Following the exercise of option 1, and in the event of failure to exercise option 2, Sun Summit and Eagle Plains shall then form a 75/25 joint venture (JV) to further explore and develop the project. The JV will hold and operate the properties, and each party will proportionately finance their share of expenditures.

Next steps

A formal agreement with industry standard terms will be prepared, and the expectation is the agreement will be settled and executed by the parties within 90 days. The terms and conditions of the formal agreement will be subject to the laws of the Province of British Columbia, Canada, and subject to regulatory approval.

A more extensive compilation of historical exploration data needs to be completed 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 data set 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. A new mineral exploration permit (MX permit) will need to be secured for any future diamond drilling. The application process will be initiated by Sun Summit shortly after execution of the formal agreement.

Sun Summit has reviewed all available data as part of the due diligence process including compilation and interpretation of available data from historical work programs. Work is continuing and will lead to recommendations for future work in consultation with Eagle Plains.

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, 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.
