Founders Metals hits 27.0 m of 20.38 g/t Au at Antino West Zone

Vancouver, British Columbia--(Newsfile Corp. - September 9, 2026) - Founders Metals Inc. (TSXV: FDR) (OTCQX: FDMIF) (FSE: 9DL0) ("Founders" or the "Company") announces drill results from the Upper Antino-West Zone ("West Zone") at its Antino Gold Project ("Antino" or the "Project") in southeastern Suriname (Figure 1). Hole FR251 returned 27.0 metres (m) of 20.38 grams per tonne (g/t) gold (Au) from 100.0 m, including 10.0 m of 43.26 g/t Au. The West Zone is located 1.2 kilometres (km) west of the established Froyo Zone and was first intersected by discovery hole FR217, approximately 50 m to the north, which returned 53.1 m of 1.21 g/t Au from surface ( announced June 23, 2026 ; Figure 2).

Colin Padget, President & CEO, commented , "This ground has been part of Founders' land package for less than a year. Going from adding it to the project, to drilling 27.0 metres of 20.38 g/t gold in FR251, one of the best single intercepts in Antino's history, is a clear demonstration of the exploration potential of this district. That result came from a disciplined process: airborne geophysics, auger sampling and systematic follow-up of the resulting anomalies, the same approach we are applying across the rest of Antino."

West Zone Highlights

High-grade gold at West Zone: 27.0 m of 20.38 g/t Au from 100.0 m in hole FR251, including 10.0 m of 43.26 g/t Au from 100.0 m (Figure 3).

Additional gold-bearing shear zone intersected to the west of FR251: 14.0 m of 1.63 g/t Au from 119.0 m, including 2.0 m of 9.86 g/t Au (FR250).

Gold mineralization style similar to the Upper Antino-Froyo Zone: gold is associated with the same alteration, veining, and structural style that hosts the high-grade mineralization in the Froyo Zone, including the recently announced 28.0 m of 14.27 g/t Au in drill hole FR249 (See August 6, 2026 news release).

The West Zone is a priority target for the rema
