Eagle Plains' Partner Sun Summit Minerals Commences Fieldwork at the Theory Project, Toodoggone District, BC

Sun Summit Minerals Corp. (SMN) and partner Eagle Plains Resources have mobilized crews to begin the 2026 fieldwork program at the Theory Copper-Gold Project in the Toodoggone Mining District, BC. The company has allocated approximately $700,000 for the 2026 Theory exploration program, which is structured in three phases.

Phase 1, which has been completed, involved 476 line-km of Airborne Magnetotelluric (MobileMT) survey work finished in June. Phase 2 is currently underway and consists of a 28-day helicopter-supported prospecting, mapping, and geochemical sampling program. Phase 3 is scheduled to follow, featuring up to 22 line-km of Induced Polarization (IP) surveys over high-priority targets in the Bev and Saboteur zones.

The release highlights 2025 grab sample results, including up to 6.42% Cu, 12.6 g/t Au, and 3,150 g/t Ag, which are interpreted as the inner shell of a porphyry system.

Concurrently, the company filed an application with the TSX Venture Exchange to extend the expiry of 2,220,750 common share purchase warrants by 12 months. The expiry date is moving from August 2, 2026, to August 2, 2027, while the exercise price remains unchanged at $0.30 per warrant.

Sun Summit Minerals Corp. (SMN) has begun fieldwork at its Theory project, marking the start of the exploration plan previously announced in May 2026. This development confirms that management is adhering to the $700,000 budget and established timeline for the initiative.

In addition to the exploration update, the company extended its warrants as standard corporate housekeeping to prevent expiry and potential dilution, a move that aligns with the firm's longer-term exploration schedule.

The announcement serves as a routine operational update, validating the company's execution without introducing new financial data, unexpected assay results, or strategic shifts. Consequently, the news is not expected to serve as a new catalyst for the stock.

Market reaction is anticipated to be neutral to marginally positive, as the 2026 fieldwork schedule had already been priced in. The stock is currently consolidating, and this update alone is insufficient to drive a breakout without accompanying drill or assay results.

Sun Summit Minerals Corp. (SMN) is an exploration-stage company focused on gold, silver, and copper projects in British Columbia's Toodoggone Mining District. Its flagship JD Project spans over 15,000 hectares and hosts epithermal Au-Ag systems, specifically the Creek and Finn zones, alongside porphyry Cu-Au potential. The company is advancing toward an inaugural MRE for Q1 2027.

The company also holds the Theory Project, a 9,676-hectare early-stage copper-gold-silver exploration property. Under an option agreement with Eagle Plains Resources, Sun Summit can earn up to 100% of the project. Recent fieldwork targets a potential porphyry system source. Additionally, the Buck Project covers 52,000 hectares of Cu-Mo porphyry-style mineralization and is fully permitted and bonded to drill.

Infrastructure support for the JD Project includes all-season road access, proximity to the Sturdee airstrip, and access to the Kemess Mine hydroelectric power grid.
