Founders Metals Hits Deep High-Grade

Mineralization at Upper Antino; 18.0 m of 6.14

g/t Gold from 450 m

Vancouver, British Columbia--(Newsfile Corp. - September 3, 2025) -

Founders Metals Inc.

(TSXV:

FDR) (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 (g/t) gold (Au)

and

5.0 m of 10.61 g/t Au

(Figure 2) from ~450.0

m vertical depth, further building on initial results from the preliminary deep drilling program as outlined

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 &

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)

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.
