Founders Metals Inc. (TSXV: FDR,OTC:FDMIF) (OTCQX: FDMIF) (FSE: 9DL0) ("Founders" or the "Company") is pleased to announce drill core assay results from its ongoing, fully funded 60,000 metre drilling campaign at the Antino Gold Project in southeastern Suriname (Figure 1). The Company's deep drilling program at Upper Antino has successfully intersected multiple zones of high-grade gold mineralization in FR138, including at 18.0 metres (m) of 6.14 grams per tonne (gt) gold (Au) and 5.0 m of 10.61 gt Au (Figure 2) from ~450.0 m vertical depth, further building on initial results from the preliminary deep drilling program as outlined on August 11, 2025.
Colin Padget, President and CEO, commented: "These results support our geological model and confirm that high-grade mineralization continues at depth, significantly increasing the potential scale of Upper Antino. High-grade intersections in drill hole FR138 include 18.0 m of 6.14 g/t Au and 5.0 m of 10.61 g/t Au demonstrating that Founders is beginning to successfully target high-grade gold at depth. We are excited about the ongoing drilling at Upper Antino and Maria Geralda and look forward to getting back out to other exploration targets this Fall."
Drilling Highlights
- High-grade depth extension success: Drill hole FR138 supports the thesis of repeating, high-grade ore shoots at over 450 m vertical depth within broader, mineralized structures (Figures 3 & 4)
- 18.0 m of 6.14 g/t Au from 550.0 m
- 5.0 m of 10.61 g/t Au from 516.0 m
- Parallel shears between Froyo and Donut: Recent intercepts demonstrate the continued growth along strike and at depth in parallel shears
- Mineralization in parallel shears to the north intersecting 15.6 m of 1.25 g/t Au from surface (FR134)
- Furthest east parallel structure confirmed to ~250 m vertical depth with 8.0 m of 1.11 g/t Au from 312.0 m (FR138)
- Gold vein intersected in recent drilling testing southern extension: assays are pending and will be released once received (Figure 5)
Geology Discussion
Systematic drilling at Upper Antino has intercepted multiple kilometre-scale, gold-bearing shears with strong vertical continuity. The current deep drilling program has doubled the vertical extent from 280 m to ~500 m vertical depth with FR138 confirming the presence of high-grade gold at these levels with 18.0 m of 6.14 g/t Au and 5.0 m of 10.61 g/t Au in drill core beginning at approximately ~450 m vertical depth.
We note the increasing width of an intrusive body (tonalite) with depth and a coincident increase in strain intensity throughout. Figure 3 shows the highest-grade intervals in drill hole FR138 occur near the footwall margin of this intrusive, with gold also present in other substantial shears up-hole.
Step-out exploration drilling approximately 500 metres north did not intersect significant gold mineralization over a 4-hole fence (FR110-113), however, gold was present over a 24-metre interval in FR129 extending Upper Antino gold mineralization by ~200 m north of previous work. Follow-up drilling intends to target west of FR110 where gold mineralization may extend following the dominant regional geologic fabric and where recent mapping/prospecting work identified quartz veins and shearing at surface.
Ongoing Work at Antino
Four drill rigs are currently turning at Antino. The Company's current activities are:
- Continue drilling along strike and at depth on Upper Antino
- Drilling at Maria Geralda with results pending
- Completing Parbo auger program
- Ongoing surface exploration programs to provide structural context for Phase 2 drilling across high-priority targets including Van Gogh, Da Vinci and Lawa
This comprehensive exploration approach positions Founders to unlock the Antino Project's full potential while systematically advancing multiple high-potential targets.

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. Rock chip samples from outcrop/bedrock are selective by nature and may not be representative of the mineralization hosted on the project.
