Founders Metals Discovers New Parallel Zone; Hits 14.5 m of 16.26 g/t Gold and 26.0 m of 4.86 g/t Gold

Vancouver, December 21, 2023 - Founders Metals Inc. (TSXV: FDR) (OTCQX: FDMIF) (FSE: 9DL0) ("Founders" or the "Company") announces drill core assay results from the Antino Gold Project in southeastern Suriname. The Company reports intercepting numerous high-grade gold intervals in a new zone parallel to the main Antino Shear Zone, more than doubling the width of the gold mineralized footprint to over 200 m. The intervals include, from separate holes, 14.5 metres* (m) of 16.26 grams per tonne (g/t) gold (Au), 26.0 m of 4.86 g/t Au, and 14.0 m of 3.65 g/t Au.

Highlights

• New gold zone discovery in step-out drilling parallel to the main Froyo Gold Zone
• Drill hole 23FR041 intercepts 14.5 m of 16.26 g/t Au from 52.7 m down hole
• Drill hole 23FR044 intercepts mineralization from surface with four major zones and one interval containing visible gold (Figure 1):
  • 11.6 m of 2.59 g/t Au down hole from surface
  • 13.0 m of 6.29 g/t Au from 42 m down hole
  • 26.0 m of 4.86 g/t Au from 56 m down hole and,
  • 6.0 m of 8.52 g/t Au from 117 m down hole
• Drill-defined gold mineralization at Froyo covers more than 500 x 200 m and extends to vertical depths of >150 m (Figure 2)

Colin Padget, Founders' CEO, commented, "We continue to expand the exceptional gold mineralization at Upper Antino, and these new results represent a major addition to the overall footprint of this robust gold system. We can now point to a sizeable Froyo volume extending more than 500 metres along strike, 200 metres wide, and over 150 metres vertical depth, and that remains open along strike and at depth. Even more exciting is that this year's drilling has tested only a fraction of the historical auger gold anomalies at Upper Antino, with similar surficial gold signatures yet to be tested at Lower Antino, Parbo, and Buese areas."

Anomalous gold mineralization extends over 8 kilometres from Upper Antino to Buese, with a similar scale signature identified at Lower Antino. The outline of Froyo Zone gold mineralization in the Upper Antino area demonstrates the scale of potential future gold discoveries on the property. The map shows only ~40% of the Project's 20,000-hectare land package.

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 Vancouver, Canada (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.
