Sun Summit drills 4.35 g/t Au over 23.5 m at JD Project

Vancouver, British Columbia--(Newsfile Corp. - October 6, 2026) - Sun Summit Minerals Corp. (TSXV: SMN) (OTCQB: SMREF) ( "Sun Summit" or the "Company" ) is pleased to report assay results from the first thirteen drill holes at the Creek Zone, part of its 2026 drill program at the Company's JD Project, Toodoggone Mining District, north-central British Columbia (the " JD Project ").

The 2026 drill program at the JD Project consisted of 16,000 meters in 55 drill holes across the Creek, Finn and Schmitt zones (see September 15 th , 2026, News Release ). Drilling was designed with two primary goals: (1) establish inaugural mineral resource estimates for the Creek, Finn and Schmitt zones, and (2) explore the lateral and vertical extents of near surface, epithermal-related gold-silver-base metal mineralization at all three targets.

Drilling at the Creek Zone successfully extended high-grade and bulk-tonnage style, epithermal-related gold-silver mineralization by approximately 100 meters along strike to the northwest where it remains open. Assay results are pending from the remaining 42 holes completed during the 16,000-meter 2026 drill program.

Highlights:

Creek Zone extension: Four drill holes evaluated the strike-extent of Creek Zone mineralization. Holes were stepped out to the northwest from 2025 drilling. All reported holes intersected gold-silver mineralization, highlights include:

23.5 meters of 4.35 g/t Au and 4.69 g/t Ag from 109.0 meters down hole including 4.50 meters of 21.8 g/t Au and 20.18 g/t Ag in drill hole CZ-26-023

32.5 meters of 3.02 g/t Au and 2.53 g/t Ag from 139.0 meters down hole including 7.57 meters of 12.15 g/t Au and 9.24 g/t Ag in drill hole CZ-26-032
