Founders Metals Provides Exploration Update

on Emerging Targets; Drills 72.0 m of 1.01 g/t

Gold at Parbo

Vancouver, British Columbia--(Newsfile Corp. - December 11, 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 drill program at the Antino Gold Project ("Antino" or the "Project") in

southeastern Suriname (Figure 1). The results include the first phase of drilling at the Parbo target and

follow-up drilling at the Da Vinci and Maria Geralda targets - three priority emerging discoveries within

the 56,000 hectare (ha) Antino Gold Project.

At Parbo, inaugural drilling has outlined broad, intrusion-hosted gold mineralization with internal high-

grade shear zones, highlighted by 72.0 metres (m) of 1.01 grams per tonne (g/t) gold (Au) including 4.0

m of 11.97 g/t Au in hole PB003, and 101.0 m of 0.62 g/t Au from surface in hole PB013. At Da Vinci,

step-outs continue to extend the shear-hosted gold mineralization, including 19.5 m of 2.31 g/t Au and

22.5 m of 1.38 g/t Au in hole DV016. At Maria Geralda, drilling has now expanded mineralization 400 m

southeast of the initial discovery, returning broad intrusion-hosted gold with discrete high-grade zones,

including 53.0 m of 0.41 g/t Au in MG006 and 12.0 m of 1.12 g/t Au in MG010, adjacent to the previously

reported 22.5 m of 11.88 g/t Au in MG003.

Colin Padget, Founders' President & CEO, commented

: "These results from Parbo, Da Vinci, and

Maria Geralda further demonstrate the scale and consistency of the gold systems emerging across

Antino. Parbo, in particular, is shaping up as a significant intrusion-hosted target with multiple shear

zones that remain open in all directions. I was especially impressed with Parbo hole PB013 which,

including a 10 m interval of dilution, returned

200 m of 0.51 g/t

from surface

. We will continue to

advance this exciting target into the new year. Da Vinci and Maria Geralda continue to deliver robust

gold mineralized intercepts within increasingly well-defined structural corridors. Each round of drilling

strengthens our geological model, guiding a focused, systematic, and value-driven approach as we plan

our 2026 exploration program."

Drilling Highlights

PARBO - Broad intrusion-hosted gold system with internal high-grade shear zones

PB003:

72.0 m of 1.01 g/t Au from 111.0 m, including 4.0 m of 11.97 g/t Au

PB013:

101.0 m of 0.62 g/t Au from surface and 77.0 m of 0.47 g/t Au from 123.0 m

PB001:

21.0 m of 0.96 g/t Au from 66.0 m and 12.0 m of 2.91 g/t Au from 262.0 m

Drilling confirms substantial gold mineralization across an

~800 m by 400 m corridor

down to

250 m vertical depth and remains open

Core logging of additional holes pending assay results indicate the

intrusive complex, shearing,

and sulphide-bearing quartz vein system extends at least 1,400 m by 800 m and to at least

275 m depth

Vertical auger sampling to depths between 10-15 m demonstrates gold mineralization extends

through the oxide zone and to surface, with auger results including 13.0 m of 1.05 g/t Au (PB011)

and 13.0 m of 0.79 g/t Au (PB013)

DA VINCI - Main zone expansion and discovery of new parallel structure

DV016:

19.5 m of 2.31 g/t Au from 21.6 m;

22.5 m of 1.38 g/t Au from 99.6 m;

plus, additional broad shear-hosted intervals of anomalous gold mineralization

DV017:

18.0 m of 0.58 g/t Au and 4.0 m of 1.77 g/t Au

DV019:

22.5 m of 0.24 g/t Au in the first hole testing a

new parallel structure 1.5 km southwest

of Da Vinci with additional holes from this target pending assay

Regional auger sampling expands the Da Vinci gold-in-auger anomaly

>1.0 km southeast

, while

mapping, LiDAR, and magnetics collectively define a

>2.5 km structural trend

linking Da Vinci to

Buese

MARIA GERALDA - 400 metre strike extension from discovery hole and broad intrusive-hosted

mineralization

MG006:

53.0 m of 0.41 g/t Au and 17.0 m of 0.31 g/t Au

MG009:

3.0 m of 2.03 g/t Au and 22.5 m of 0.34 g/t Au

MG010:

12.0 m of 1.12 g/t Au, 2.0 m of 5.12 g/t Au, and 3.0 m of 1.71 g/t Au, plus additional

mineralized intervals (see table 1)

Drilling extends the mineralized trend

400 m southeast

, for a

total of over 600 m of drill-

confirmed gold-mineralized strike

Auger sampling extends the surface anomaly a further

950 m southeast towards the Van Gogh

target, bringing the total length of surface anomaly to 2 km.

Geological Discussion

PARBO

Parbo is defined by a

1.2 km × 0.6 km historical gold-in-auger anomaly

with local 1 m auger

samples grading up to 51.42 g/t Au*. Founders' Phase 1 drilling targeted mapped intrusive contacts and

shear zones to successfully confirm broad, continuous zones of gold mineralization within a granodiorite

intrusive body. The current drill-defined mineralized corridor measures

~800 m × 400 m and down to

~250 m depth

, remaining open in all directions. Geological logging from recent step-outs suggests the

broader intrusive complex extends at least

1.4 km × 0.8 km

and to

~275 m vertical depth

. Regional

auger sampling has also delineated a

2.8 km NW-trending anomaly

coincident with a major linear

feature identified in magnetic and LiDAR datasets. Future drilling will focus on targeting these potentially

higher-grade contact zones within the Parbo target area and numerous additional intrusive centres

identified across the Property.

DA VINCI

Drilling at Da Vinci extends the

highest-grade gold zones strike length to ~200 m

confirming

multiple stacked shears hosted within a dominantly sedimentary rock package. Initial drilling of a newly

identified parallel structure, located

1.5 km southwest

, has returned encouraging mineralization over

significant widths with 22.5 m of 0.24 g/t Au in DV019. This new zone represents part of a newly

identified prospective structural corridor that extends 2.5 km between Da Vinci to Buese.

MARIA GERALDA

Follow-up drilling southeast of discovery hole MG003 (22.5 m of 11.88 g/t Au; in oxide from 18 m down

hole) intercepted shear-hosted mineralization along predominantly intrusive contacts and broader

mineralized intervals within the intrusive body itself. Follow-up drilling and a thorough review of the

structural data suggest that the high-grade zone in hole MG003 may represent a sub-horizontal shoot or

rod-like body perpendicular to the main NW-trending shear zone - a common product of high-angle

movement along such structures. Alternatively, narrower (< 5 m) intervals of shearing and quartz veining,

locally containing anomalous gold values, were intercepted in hole MG005, ~80 m vertical distance

below the MG003 saprolite interval. Additional drilling is needed to better understand the nature of high-

grade gold mineralization at this target, however, these drill results extend the gold mineralized footprint

at Maria Geralda to over 600 m, whilst anomalous results from recent surface geochemistry (auger)

suggests the gold system extends more than double that to approximately 1.3 km, and the target retains

considerable potential for future exploration work.

The 2025 program continues to demonstrate that Antino hosts

multiple mineralizing centres

across a

regional structural framework with both high-grade shear zones and broad intrusion-hosted systems. All

eight target areas drilled to date have returned significant gold mineralization. Gold mineralization at

Antino occurs in several settings:

Shear zones within folded metavolcanic-metasedimentary units (Froyo, Da Vinci, Van Gogh)

Along intrusive contacts (Donut, Maria Geralda)

Within high-strain zones internal to intrusive bodies (Parbo, Lower Antino, Buese)

The Company is currently preparing its 2026 exploration plan to incorporate drill-ready targets from the

newly acquired expanded concession area and incoming high-resolution airborne geophysics and

expanded regional geochemical surveys. An exploration and drilling plan for 2026 will be released early

in the coming year along with additional pending drill assay results from Parbo, Da Vinci, Van Gogh, and

Lower Antino.

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.
