Drill Results

Founders Metals Expands Upper Antino; Hits

33.0 m of 3.50 g/t Gold

Vancouver, British Columbia--(Newsfile Corp. - May 21, 2025) -

Founders Metals Inc.

(TSXV: FDR)

(OTCQX: FDMIF) (FSE: 9DL0) ("Founders" or the "Company") announces drill core assay results from

the Antino Gold Project ("Antino" or "Project") in southeastern Suriname (Figure 1). The Company

reports high-grade gold mineralization at Upper Antino including

33.0 metres (m) of 3.50 grams per

tonne (g/t) gold (Au)

in drilling east of the Main Froyo Shear ("Froyo"). Additional drilling results extend

gold mineralization north 125 m, increasing total strike length of Froyo to ~1.7 kilometres (Figure 2).

Drilling Highlights

Growth-focused drilling expands high-grade gold mineralization in parallel structures (Figures 2 &

3):

33.0 m of 3.50 g/t Au

and

19.0 m of 0.84 g/t Au

(FR114)

13.0 m of 2.00 g/t Au

(FR082)

4.0 m of 5.92 g/t Au

(FR105)

Broad gold zones and 125 m northward extension:

41.9 m of 1.06 g/t Au

(FR099)

12.0 m of 1.51 g/t Au

and

22.5 m of 0.50 g/t Au

(FR101), extending gold mineralization

north in two parallel mineralized zones

Colin Padget, President & CEO, commented, "These results clearly demonstrate Upper Antino's growth

potential in multiple directions. Gold mineralization continues eastward over substantial intervals while

our step-out drilling has successfully expanded the northern boundary by 125 metres. The two broad

intervals in hole FR114 align well with our mineralization and structural models and suggest there is

potential to 'connect-the-dots' between Froyo and Donut. Additionally, while we have seen some

increases in assay turnaround times and have been focusing on certain corporate items, we anticipate

releasing additional results from our earlier-stage exploration targets along-side a comprehensive

overview in the coming weeks."

Drilling continues to expand Upper Antino gold mineralization and Figure 4 provides a 12-month

snapshot showing the growth of the mineralized footprint over that time. In this release, drill hole FR114

intersecting 33.0 m of 3.50 g/t Au, is one of several holes planned to target further eastward growth of

Froyo gold mineralization and determine if additional parallel zones link Froyo with the Donut target.

Drillhole FR101 intercepted two distinct zones of mineralization with the shallower 22.50 m interval of 0.5

g/t Au beginning at 27.60 m and potentially a new shear as the deeper 12 m of 1.51 g/t Au aligns well

with the previously reported 8.0 m of 2.08 g/t Au in hole FR095. These are encouraging intercepts

indicating additional northward potential and drill holes are planned further north to continue testing these

structures.

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.
