FOUNDERS METALS PROVIDES EXPLORATION UPDATE ON EMERGING TARGETS AT ANTINO

Founders Metals Inc. has made significant progress in its surface exploration program at the Antino gold project in southeastern Suriname. The company has completed extensive sampling at the Maria Geralda and Parbo targets, setting the stage for upcoming drill programs during the current dry season.

Founders is executing an aggressive exploration strategy targeting high-grade prospects, including Maria Geralda, Parbo, Van Gogh, Da Vinci and Lawa, while systematically expanding known mineralization at Upper Antino, Buese and Lower Antino.

"Surface exploration continues to build a robust pipeline of high-quality drill targets that our team will systematically test through diamond drilling," said Colin Padget, president and chief executive officer. "The ongoing work at Maria Geralda and Parbo reveals significant opportunities for growth, further validating Antino's Tier 1 potential. Phase 2 drilling is under way at Maria Geralda and, with the rainy season ending, we're eager to return to Van Gogh, Da Vinci and Lawa to follow up on earlier drilling success."

Key surface exploration results

Maria Geralda target -- continues to demonstrate exceptional potential:

• 1.3-kilometre (km) strike length of anomalous auger samples with grades reaching up to 7.47 grams per tonne (g/t) gold (Au);
• 516 auger samples collected to date, including 314 anomalous (more than 0.02 g/t Au) results;
• Strong hit rate: 61 per cent of samples anomalous, with 25 per cent exceeding 0.1 g/t Au;
• Continuing sampling designed to test the southeastern extension toward Van Gogh.

Parbo target -- compelling high-grade vein system within large-scale auger gold anomaly:

• Historical 1,200-by-600-metre (m) auger anomaly with samples up to 51.42 g/t Au:
  • 1,344 historical auger samples with 83 per cent anomalous (more than 0.02 g/t Au) and 46 per cent exceeding 0.1 g/t Au;
• Newly discovered 15 m wide oxidized shear zone at surface with abundant quartz veining and grab samples grading up to 26.85 g/t Au;
• Historical trench results including 49.0 m of 1.02 g/t Au;
• Limited historical drilling intersected up to 12.0 m of 3.36 g/t Au;
• Commencement of auger and trenching programs to refine future phase 1 drilling targets.

Geological context and strategy

The company's exploration strategy targets structures associated with the central Guiana shear zone, a major regional control on gold mineralization. Recent surface work has successfully extended the Maria Geralda anomaly 1.3 km south of the discovery hole (22.5 m core length of 11.88 g/t Au in MG003), with the mineralizing structure remaining open in both directions along strike.

Gold mineralization at Maria Geralda occurs in two distinct styles:

• High-grade shear-hosted mineralization along the contact between metavolcanic-metasedimentary rocks and intrusive complex;
• Lower-grade bulk-tonnage mineralization within the intrusion itself.

At Parbo, surface teams have identified a high-grade vein system within felsic to intermediate intrusive rocks similar to Donut and Lower Antino. Recent mapping and trenching have exposed a 15 m wide mineralized shear zone characterized by intense silicification, quartz veining and sericite alteration, with up to 5 per cent pyrite in brittle fractures, a feature commonly associated with high-grade mineralization elsewhere on the property.

Next steps

With the dry season now under way, Founders plans to:

• Continue systematic drilling at Maria Geralda, with results pending;
• Complete auger program at Parbo ahead of phase 1 diamond drill program in Q4 (fourth quarter);
• Execute surface exploration programs to provide structural context for phase 2 drilling across other high-priority targets, including Van Gogh, Da Vinci and Lawa.

The comprehensive exploration approach positions Founders to unlock the full potential of the Antino gold project while systematically advancing multiple high-grade targets.

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 historical surface and alluvial mining to date. The company is systematically advancing one of Suriname's most promising gold exploration and development opportunities with drill-confirmed, district-scale potential. Founders is committed to responsible exploration and community engagement, and is delivering long-term value to shareholders through technical excellence and strategic growth in the Guiana shield.

Quality assurance and quality control (QA/QC)

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 per cent passing a 2.35-millimetre (mm) screen, riffle split (700 grams (g)) and pulverized to 85 per cent passing 88 microns. 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 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.
