Founders Metals hits 28.0 m of 14.27 g/t Au at Upper Antino

Vancouver, British Columbia--(Newsfile Corp. - August 6, 2026) - Founders Metals Inc. (TSXV: FDR) (OTCQX: FDMIF) (FSE: 9DL0) ("Founders" or the "Company") announces results from the Upper Antino target area at its Antino Gold Project ("Antino" or the "Project") in southeastern Suriname (Figure 1). Recent exploration drilling at Upper Antino intersected 28.0 metres (m) of 14.27 grams per tonne (g/t) gold (Au) from 433.0 m in drill hole FR249, a 50 m down-dip extension of previously reported FR175 (10.0 m of 5.90 g/t Au).

Colin Padget, President & CEO, commented, "These results demonstrate meaningful high-grade growth potential at Upper Antino. FR249 is one of the strongest holes we've drilled at Antino, returning 28.0 metres of 14.27 g/t gold — grade we have typically seen only within the high-grade Froyo core, now intersected well outside it. By extending this mineralization down-dip from FR175, the hole potentially demonstrates strong vertical continuity of a new high-grade zone. Establishing its scale is a priority for our ongoing drilling."

Highlights

Broad high-grade gold: 28.0 m of 14.27 g/t Au from 433.0 m (~340 m vertical) in FR249, a 50 m down-dip extension from the previously reported drill hole FR175 intersecting 10.0 m of 5.90 g/t Au

Multiple stacked zones: Drill hole FR249 intersected multiple gold zones with downhole widths ranging from 6.0 m to 28.0 m (Figures 2 and 3)

Growing gabbro-hosted target: gold mineralization occurs within a gabbro unit widening at depth, representing a progressively larger target for follow-up drilling

Geological Discussion Ongoing drilling at Upper Antino is testing the down-dip continuation of the multiple gold-bearing shear zones that define the target. Hole FR249 cut four stacked, sub-parallel shears between 285.0 m and 461.0 m down-hole, the deepest of which returned 28.0 m of 14.27 g/t Au from 433.0 m (~340 m vertic
