Sun Summit Commences Fully Funded 10,000 Meter Drill Program at the JD Project, Toodoggone Mining District, B.C.

Executive Summary

• Sun Summit Minerals has commenced its fully funded 2026 exploration drill program at the JD Project in north-central British Columbia, planning over 10,000 meters of drilling across the Creek and Finn zones.
• The program is strategically designed to generate data for an inaugural mineral resource estimate (MRE) anticipated in Q1 2027, building upon significant historical and recent drilling intercepts.
• A project-wide airborne mobile magnetotelluric (MobileMT) geophysical survey is concurrently underway to characterize alteration zones and identify new drill targets.

Key Details

• Drill Program Scope: Fully funded 2026 program targeting 10,000 meters total across Creek and Finn zones.
• Rig Deployment: One drill rig is currently operating at the Creek Zone; a second rig begins operations in the coming days; one rig will relocate to the Finn Zone in the coming weeks once drill pads are constructed.
• Creek Zone Drilling: Up to 5,000 meters planned to evaluate vein-controlling structures over a 600-meter strike length and 350-meter vertical extent. Focus on step-out and infill holes for near-surface, high-grade, bulk-tonnage gold. Follows up on CZ-25-021: 81.0 meters @ 4.80 g/t Au (including 34.0 meters @ 9.07 g/t Au).
• Finn Zone Drilling: Up to 5,000 meters planned to evaluate the down-dip and strike extent of a volcaniclastic unit over a ~650m x 350m footprint. Focus on step-out, infill, and exploration holes for near-surface bulk-tonnage gold-silver. Follows up on FZ-25-002: 17.0 meters @ 2.31 g/t Au & 113.1 g/t Ag (including 6.0 meters @ 5.30 g/t Au & 157.9 g/t Ag).
• Geophysical Survey: Airborne MobileMT survey underway across the entire JD Project (740 line kilometers, 250-meter spacing, NW-SE orientation) to image subsurface resistivity/conductivity to depths of 1-2 kilometers for target generation.
• MRE Timeline: Inaugural mineral resource estimate for the Finn and Creek zones is expected in Q1 2027.
• Option Grant: 250,000 stock options granted to investor relations service providers at an exercise price of $0.15 per share, with a 3-year expiration and 12-month vesting schedule, subject to TSX Venture Exchange approval.
• Project Location & Infrastructure: JD Project covers >15,000 hectares in the Toodoggone Mining District, located 450 km NW of Prince George and 25 km N of the Sturdee airstrip, proximal to Kemess mine infrastructure (roads, hydro power).

Notable Quotes

• "We are excited to have officially launched our fully funded 10,000 meter drill program at our JD Project," said Niel Marotta, CEO. "This program will include the most significant drilling at JD since the late 1990s. The 2026 program is the largest drill program planned since Sun Summit optioned the JD property in 2024, and represents more meters of drilling at JD than the last two drill seasons combined. Importantly, this program will drive the JD project towards an inaugural mineral resource estimate, expected in Q1 of 2027."
