Sun Summit Announces the Completion of the Inaugural 2025 Exploration Program at the Theory Project, Toodoggone Mining District

Sun Summit Minerals Corp. announced the completion of its inaugural 2025 exploration program at the Theory Project, located in the Toodoggone Mining District of British Columbia. The program involved prospecting, geological mapping, and geochemical sampling. Preliminary results from this work suggest the potential for a concealed porphyry system and have successfully identified new targets within the project area. The company has stated that assay results from the geochemical sampling are pending. Niel Marotta, CEO, expressed satisfaction with the early prospecting work and the potential for a large porphyry system at Theory, emphasizing its contribution to Sun Summit's asset base in the Toodoggone region alongside the JD Project. The program aims to define drill targets for future exploration seasons.

This news is a routine positive development for Sun Summit Minerals. The completion of the initial exploration program at the Theory Project, a newly optioned asset, is in line with the company's previously stated plans and minimum expenditure commitments for 2025. The program successfully achieved its objective of defining future drill targets and has yielded encouraging preliminary results suggesting porphyry potential. This moves the Theory project forward from conceptual target to a more refined exploration stage.

However, the impact is not material for several reasons: * Early Stage: This is an inaugural exploration program, focused on reconnaissance-level work (prospecting, mapping, sampling), not drilling or resource definition. * Pending Results: The key data, assay results, are still pending. The "preliminary results" and "potential for a concealed porphyry system" are qualitative and indicative, not quantitative or definitive. * Expected Progression: The progression of exploration at Theory was anticipated following the formalization of the option agreement in March 2025 and the planning announced in August 2025. The company had committed to a minimum $200,000 expenditure for 2025 at Theory to define targets. The completion of this work, therefore, meets expectations rather than exceeding them. * Focus Shift: While positive, this news is overshadowed by the more advanced and immediately impactful exploration activities at the JD Project, which recently delivered high-grade drill results (CZ-25-007) and identified a major 8.5km porphyry anomaly. JD also saw a significant increase in its 2025 drill program and completed over 6,800 meters of drilling, with many assay results pending, which will likely be more material.

The news indicates sound operational execution but does not fundamentally alter the company's risk profile or valuation in the absence of concrete assay results or resource-defining information.

Sun Summit Minerals Corp. (TSXV: SMN, OTCQB: SMREF) is a Canadian mineral exploration company focused on the discovery, expansion, and advancement of district-scale gold and copper assets in British Columbia.

The company's primary projects include: * JD Project: Located in the Toodoggone Mining District of north-central British Columbia, this is a large (over 15,000 hectares) and highly prospective project. It hosts both high-grade epithermal gold-silver mineralization (e.g., Creek and Finn zones) and porphyry-related copper-gold targets (e.g., McClair, Belle, Fericrete). Recent exploration has defined an 8.5km long chargeability-high anomaly, enhancing its porphyry potential. The JD Project is actively being explored with significant drilling, geophysical, and geochemical programs. * Buck Project: Situated in central British Columbia, the Buck Project is 100% owned by Sun Summit. An inaugural Mineral Resource Estimate (MRE) on the Buck Main deposit was announced in February 2025, outlining significant indicated and inferred gold equivalent resources in an open-pit shell. It is characterized by intermediate-sulfidation epithermal gold-silver-zinc mineralization. * Theory Project: This project, covering approximately 10,000 hectares in the Toodoggone Mining District, was recently optioned from Eagle Plains Resources Ltd. It borders Thesis Gold's Ranch project and is within 10km of Sun Summit's JD Project, creating a combined 25,000-hectare strategic land package. Theory is being explored for epithermal-related gold and large bulk-mineable porphyry-related copper-gold targets, similar to its neighbors.

The company aims to leverage the geological prospectivity of these regions, particularly the Toodoggone District, which is experiencing heightened corporate activity.
