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

The highlight intercept occurs where the mineralized structures transect a large gabbro body. Gold mineralization at Upper Antino remains structurally controlled, with the gabbro providing a favourable host: the competent, brittle unit fractures readily where the shears cut through it, opening space for the quartz veining that carries high-grade gold, while its iron-rich composition promotes gold deposition from the mineralizing fluids. Because the unit widens down-dip, the structures intersect progressively greater volumes of this favourable host at depth. Mineralization remains open, and follow-up drilling is planned to track the high-grade structure along strike and down-plunge, with emphasis on its intersection with the gabbro.

The remaining holes in this release tested parallel shears across Upper Antino at a range of depths, returning results consistent with the multi-zone character of the target, including 3.0 m of 6.06 g/t Au from 45.6 m in FR231 and a broad interval of 56.0 m of 0.40 g/t Au from 351.0 m, including 10.0 m of 1.10 g/t Au in drill hole FR241.

Intervals are down-hole depths. True widths of mineralization are unknown at this time based on currently available results and observations. All are diamond drill holes. Interval average grades are calculated with un-capped gold assays, as insufficient drilling has been completed to determine capping levels for higher-grade gold intercepts. Widths are calculated using a 0.10 g/t gold cut-off grade with <5.0 m of internal dilution of zero grade material, and a minimum composite length of 2.0 m. Intervals below 3.0 gram-metres are omitted.

Quality Assurance and Control
Samples were analyzed at FILAB Suriname, a Bureau Veritas Certified Laboratory in Paramaribo, Suriname (a commercial certified laboratory under ISO 9001:2015). Samples are crushed to 75% passing 2.35 mm screen, riffle split (700 g) and pulverized to 85% passing 88 µm. Samples were analyzed using a 50 g fire assay (50 g aliquot) with an Atomic Absorption (AA) finish. For samples that return assay values over 5.0 grams per tonne (g/t), another cut was taken from the original pulp and fire assayed with a gravimetric finish. Founders Metals inserts blanks and certified reference standards in the sample sequence for quality control. External QA-QC checks are performed at ALS Global Laboratories (Geochemistry Division) in Lima, Peru (an ISO/IEC 17025:2017 accredited facility). A secure chain of custody is maintained in transporting and storing of all samples. Drill intervals with visible gold are assayed using metallic screening. Diamond drill core is HQ diameter through oxide intervals and predominantly NQ diameter in deeper drilling. All samples are half core, split using a diamond saw Rock chip samples from outcrop/bedrock are selective by nature and may not be representative of the mineralization hosted on the project.
