Founders Metals Increases Confidence in Regional Exploration Targets at Antino

Vancouver, August 26, 2024 - Founders Metals Inc. (TSXV: FDR) (OTCQX: FDMIF) (FSE: 9DL0) ("Founders" or the "Company") provides a corporate update and outlines regional exploration targets at the Antino Gold Project ("Antino" or "Project") in southeastern Suriname. The Company's surficial team is successfully developing key targets for future surface exploration and drilling, including Lower Antino, Lawa, and the Southern Froyo Extension. Founders intends to expand its drill program to include an initial 1,500 metres (m) at Lower Antino, commencing mid-September.

Founders' Management and Board of Directors ("Insiders") recently sold Company shares for taxation purposes connected with the exercise of Restricted Share Units and resulting tax implications due to the Company's stock price appreciation over the last 18 months. Founders' management organized a block trade with an existing institutional shareholder at market value ensuring no undue pressure on the stock. The related insider transactions will be filed on SEDI later today.

Highlights

Lower Antino

• Lower Antino is a high-priority target with over 25% of Founders grab samples grading >0.3 grams per tonne (g/t) gold (Au) and up to 20.4 g/t Au
• Historical results include auger samples with up to 49.3 g/t Au and very high-grade grab sample results, including two samples collected from shear-zone hosted quartz veins grading 144 g/t Au and 340 g/t Au
• Auger sampling reveals new >2.5 kilometre (km) gold trend hosting similar structures and geological features as the Froyo Gold Trend in Upper Antino
• Ground preparation underway for Lower Antino drilling to start in mid-September

Lawa

• New prospect identified by Founders in May 2024
• Completely unexplored area with three major gold-mineralized trends including two large intrusions along separate structures over a combined 2.7 km strike length

Southern Froyo Extension

• Recent grab sample of 57.4 g/t Au collected 1,500 m southeast of Froyo indicating the potential for repeat zones of high-grade gold mineralization similar to Froyo along the broader +10 km Antino gold trend that extends from Upper Antino to Buese

"Our regional exploration work continues to highlight the scale of the gold system at Antino and underscores the property's potential for additional new discoveries," commented President and CEO, Colin Padget. "Our surficial team is making significant progress toward refining existing targets to drill-ready status and identifying new areas of interest for on-the-ground follow-up. We now have a considerable pipeline of high-quality, well-defined targets and plans are in place to increase the number of active drills over the coming months."

Geology Discussion

Lower Antino is a high-priority drill target. Historical auger sampling identified an approximately 1.5 km wide and 2.0 km long gold anomaly with samples grading up to 49.3 g/t Au. The gold anomaly overlaps a large fold immediately south of the east-west Antino Creek Fault. The fold is easily identified in regional airborne magnetics data and has a distinct topographic feature in LiDAR. Founders' geologists recently mapped multiple gold-bearing shears uncovered by artisanal mining at Lower Antino with grab sample grades as high as 20.4 g/t Au. The shear-hosted mineralization occurs in, and is associated with, up to 2-metre-wide quartz and quartz-carbonate northeast veins with similar alteration assemblages, textures, and host-rocks as Upper Antino.

The most recent Founders discovery is the Lawa prospect. This new area has a 2.7 km strike length and demonstrates three significant trends. Lawa includes two, large volume intrusions along separate, distinct mineralizing structures. These intrusions exhibit a moderate to high density of quartz veining, variable pyritization, and strong sericite alteration. In addition to the intrusive suite in the northern extent of Lawa, Founders also uncovered a high-grade vein set in the southern extent of the area, with rock assays grading up to 6.7 g/t Au. Further exploration, including up to 1,500 auger samples, 2 km of trench sampling, and 250 rock samples, is planned for fall of 2024 to fully assess the potential and prepare for drilling in H1 2025.

Utilizing both LiDAR and air magnetics, the surficial team has identified zones that share similarities with the main Froyo Gold Zone. Founders recently received assay results from a surface grab sample with 57.4 g/t Au between Froyo and Buese, representing the possibility for repeated zones of high-grade gold mineralization within the broader 10 km gold trend at Antino.

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.
