Sun Summit Minerals: Advancing District-Scale Gold and Copper Projects in British Columbia

Market Focus

Sun Summit Minerals is a Canadian mineral exploration company focused on district-scale gold, silver and copper assets in British Columbia. Its flagship assets include the 100%-owned Buck Project near Houston and the JD Project and Theory Project in the Toodoggone district. The Buck Project recently received its inaugural NI-43-101 Mineral Resource Estimate, demonstrating significant near-surface bulk-tonnage gold-silver-zinc mineralization.

Platform and Strategy

Sun Summit’s strategy is to systematically advance its multi-asset portfolio via delineation of defined resources, targeted follow-up drilling and exploration of broader discovery potential. Key elements of the strategy include:

• Defining and expanding the known resource at the Buck Project through drilling, while optimizing metallurgy and assessing economics.

• Advancing the JD and Theory Projects in the Toodoggone district by executing fully funded exploration programs in 2025 designed to generate new targets and eventually convert prospects into defined resources.

• Maintaining strong exploration discipline, leveraging British Columbia’s mining-friendly jurisdiction, infrastructure and known mineral belts.

Recent Progress and Growth

• At the Buck Project, Sun Summit filed the inaugural Mineral Resource Estimate for the Buck Main zone in early 2025: An Indicated resource of approximately 1.15 Mt at ~0.519 g/t AuEq and an Inferred resource of ~52.2 Mt at ~0.489 g/t AuEq.

• The discovery cost metric is extremely efficient, with average drill cost of CAD $18 per AuEq ounce included in the MRE.

• At the JD Project, the company commenced its fully funded ~C$6 M 2025 exploration program including over 5,000 m of drilling plus geophysical and geochemical surveys.

• The Theory Project exploration program was likewise completed in 2025, positioning the company to follow up on generated targets.

Partnerships and Strategic Positioning

Sun Summit is positioned in jurisdictions with strong infrastructure, stable governments and proven mining history. Its assets in B.C. are located near active development projects and within established mineral belts, giving the company leverage to both resource-driven growth and discovery upside.

Leadership and Capital Markets Strategy

Sun Summit is led by Chief Executive Officer Niel Marotta, under whose leadership the company is executing a disciplined, discovery-focused program. The company maintains active investor communications and regularly updates stakeholders on exploration progress and technical milestones.

Near-Term Catalysts

• Additional assay results from ongoing drilling at the JD Project and infill/step-out drilling at Buck.

• Metallurgical test results and economic study initiation at the Buck Project following the MRE.

• Exploration advancement at the Theory Project with newly generated targets, and further drilling campaigns planned.

• Corporate updates on drilling progress, resource growth and potential partnerships or joint ventures.

Conclusion

Sun Summit Minerals enters late 2025 with a defined resource at Buck, fully funded exploration programs across two additional projects and significant discovery leverage in British Columbia. With a seasoned management team, a multi-asset pipeline and a focus on systematic growth, the company is well-positioned to deliver value through resource conversion and new discoveries in a mining-friendly jurisdiction.
