Founders Metals hits 53.1 m of 1.21 g/t Au, Froyo Zone intersects 12.21 g/t Au

Vancouver, British Columbia--(Newsfile Corp. - June 23, 2026) - Founders Metals Inc. (TSXV: FDR) (OTCQX: FDMIF) (FSE: 9DL0) ("Founders" or the "Company") announces drill results from the Upper Antino target area at the Antino Gold Project ("Antino" or the "Project") in southeastern Suriname. The Company has made a new gold discovery 1.2 kilometres (km) west of Upper Antino, where hole FR217 returned 53.1 metres (m) of 1.21 grams per tonne (g/t) gold (Au) from surface in a previously untested area. Drilling also continues to demonstrate that Upper Antino is strongly mineralized at depth, highlighted by 9.0 m of 12.21 g/t Au from 320 m vertical depth, together with 37.0 m of 3.27 g/t Au from 209.0 m in the same hole (FR230).

Upper Antino Drilling Highlights New discovery 1.2 km west of Upper Antino: 53.1 m of 1.21 g/t Au from surface (FR217) - new discovery targeted by a surficial geochemical anomaly More than a kilometre beyond the known mineralized footprint of Upper Antino, opening a new target in previously untested ground within the Antino land package. Follow-up drilling is underway. High-grade gold across multiple zones at Upper Antino: 9.0 m of 12.21 g/t Au from 408.0 m (FR230) approximately 320 m vertical depth and 37.0 m of 3.27 g/t Au from 209.0 m (FR230) Additional high-grade gold intersected in northern follow-up drilling: 3.0 m of 29.17 g/t Au from 101.0 m (FR219) 100 m up-dip extension of high-grade from infill drilling: 33.0 m of 2.15 g/t Au from 85.0 m (FR225) Shallow mineralization on the main shear that links the near-surface zone to the deeper high-grade intercepts, reinforcing grade continuity from surface to depth Colin Padget, President & CEO, commented , "Today's results demonstrate further growth of the gold system at Upper Antino.

To the west, we have made an entirely new discov
