Founders Metals Hits 22.5 M Of 11.88 G/T Gold In New Discovery At Maria Geralda

(MENAFN- Newsfile Corp) Vancouver, British Columbia--(Newsfile Corp. - June 24, 2025) - Founders Metals Inc. (TSXV: FDR) (OTCQX: FDMIF) (FSE: 9DL0) ("Founders" or the "Company") announces a new high-grade gold discovery at its Antino Gold Project ("Antino" or "Project") in southeastern Suriname (Figure 1). The Company reports a 22.5 metre (m) interval of 11.88 grams per tonne (g/t) gold (Au) at Maria Geralda, a new exploration target approximately 5 km SE of Lower Antino. The drilling follows up on systematic surface exploration, including prospecting, mapping, and augering programs that identified a 500 m by 400 m gold anomaly at surface.

Highlights

• First-ever drilling at Maria Geralda delivers exceptional results with 22.5 m of 11.88 g/t Au (MG003)
• Discovery validates systematic exploration approach with auger sampling identifying a 500 m by 400 m gold anomaly at surface where 54% of samples returned assays above 0.1 g/t Au
• Significant expansion potential with the discovery zone open along strike and to depth, supporting plans for follow-up drilling in 2025

Colin Padget, President & CEO of Founders, commented, "While weather has limited our access to other exploration targets recently, we were pleased to maintain ready access to Maria Geralda and follow up on early surface results. This outstanding start to drilling at Maria Geralda further validates our exploration approach across the 200 km2 Antino land package. The 22.5 m interval grading 11.88 g/t Au represents some of the highest-grade mineralization we've encountered to date. These results demonstrate the substantial discovery potential that exists beyond the property's current established zones. Between this discovery, recent expansions at Upper and Lower Antino, and our ongoing 2025 exploration program, we see significant opportunity to build shareholder value."

Maria Geralda is located along a major structural corridor on a northwest-trending lineament at the geologic boundary between intrusive rocks and mixed metavolcanic-metasedimentary formations. The discovery hole was designed to test the geochemical anomaly identified through the Company's auger sampling program. Founders plans to follow-up with systematic step-out drilling to define the extent of mineralization along strike and to depth.

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.
