Founders Metals Extends Buese Gold

Mineralization over 1,000 m & Intersects 21.6

m of 2.38 g/t Au

Vancouver, British Columbia--(Newsfile Corp. - April 23, 2025) -

Founders Metals Inc.

(TSXV: FDR)

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

Buese Prospect ("Buese") at its Antino Gold Project ("Antino") in Suriname. Buese covers over 600

hectares (ha) and is ~6 kilometres (km) southeast of Upper Antino (Figure 1). The Company reports 6.0

metres (m) of 2.33 grams per tonne (g/t) gold (Au) (BU025) in northwest step-out drilling along strike of

the main Antino Gold Trend. Combined with further broad intervals of intrusion-hosted gold

mineralization including 21.6 m of 2.38 g/t Au (BU014) and 112.0 m of 0.55 g/t Au (BU019) in the central

Buese area, the step-out drilling indicates significant potential for further growth.

Highlights

Step-out drilling 1,000 m northwest from previously released results demonstrates significant

expansion along strike of regional scale mineralizing structure (Figure 2)

Results continue to confirm bulk tonnage potential (Figure 2)

Positive initial results from in-progress Buese tailings auger drill program

230 one-metre auger samples collected over 61 holes up to 10 m deep

41 samples over 1.00 g/t Au

Gold ranges from 0.10 g/t Au - 3.39 g/t Au with an average grade of 0.64 g/t Au

15.6 m of 0.45 g/t Au of tailings in diamond drill hole BU002 (previously released)

Buese tailings processed from primary materials cover an area of ~1.3 km²

Colin Padget, President & CEO, commented, "These results demonstrate the scale and continuity of

gold mineralization emerging at Buese. The broad, intrusion-hosted intervals, along with the discovery of

a parallel zone, further reinforces our excitement about the opportunity Buese represents for Founders.

Work is ongoing to further understand the potential economic opportunity that the Buese tailings may

offer in future production scenarios, and we are encouraged by initial results. Though we have

experienced some slowdown in assay turnaround time due to the increasing exploration activities in

Suriname, we are still on track to hit our 60,000-metre drilling goal for 2025. Upcoming news will include

some in-progress corporate items along with more drilling results."

Buese Exploration

The second phase of drilling at Buese focused on exploring outside of artisanal mining areas to

demonstrate the concept of a multi-kilometre scale gold system focused within, and on the margins of

large tonalitic intrusions.

Intrusion-hosted drilling results include 21.6 m of 2.38 g/t Au in drill hole BU014 and 112.0 m of 0.55 g/t

Au in BU019. Step-out drilling to the west in BU018 intersected 6.0 m of 6.38 g/t Au, indicating the

presence of a parallel zone of gold mineralization. Collared over 1,000 m northwest of any previously

known mineralization BU025 returned 6.0 m of 2.33 g/t Au, confirming both scale and an extension of the

mineralized system.

Concurrent with Buese drilling, surficial teams have been developing new adjacent targets that share

similar structural and lithological features as the mineralized bodies within Buese. These efforts have

successfully developed a new emerging trend(s) northeast of Buese, with rock samples grading up to

8.98 g/t Au.

Buese Tailings

New and ongoing auger drilling of tailings piles from historical artisanal gold mining at Buese

demonstrate consistent gold grades averaging 0.64 g/t Au, with up to 3.39 g/t Au samples. The

homogeneity in gold grades over a large area returned in initial tailings results validate both the

economic potential of the tailings, as well as the consistent head grade produced by the artisanal

miners. These results support diamond drilling results which indicates strong bulk tonnage potential

within the targeted tonalitic intrusions and associated structures at the Buese prospect.

About Founders Metals Inc.

Founders Metals is a Canadian-based exploration company focused on advancing the Antino Gold

Project located in Suriname, South America, in the heart of the Guiana Shield. Antino is 20,000 hectares

and has produced over 500,000 ounces of gold from surface and alluvial mining to date1. The Company

is fully financed for up to 60,000 metres of drilling in 2025.

Quality Assurance and Control

Results from 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 10.0 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.
