Founders Metals Commences Airborne Geophysics and Auger Sampling Programs at Antino
Vancouver, British Columbia, September 18, 2025 – Founders Metals Inc. (TSX-V: FDR, OTCQX: FDMIF, FSE: 9DL0) ("Founders" or the "Company") is pleased to announce the start of property-wide geophysical and geochemical surveys at the Antino Gold Project (“Antino” or “Project”) in southeastern Suriname (Figure 1). The surveys are intended to support growth-focused drilling around current targets, further improve the Company’s understanding of regional-to-deposit scale controls on gold mineralization, and identify new exploration targets.
Colin Padget, President & CEO, commented “More than half of the Antino Property remains completely unexplored by modern systematic exploration methods. This fall we intend to complete property-wide auger sampling at a spacing that has been effective at identifying major gold occurrences elsewhere at Antino. Additionally, the concurrent airborne geophysical surveys use the latest technology to provide high-resolution datasets that we believe are key to unlocking the full exploration potential of the target-rich geological environment at Antino. We are continuing aggressive exploration drilling on the project with our ongoing 60,000 m program, and we look forward to providing an update to the market with results in the near-term.”
Auger Sampling
As shown in Figure 2, extensive property wide auger sampling programs comprising approximately 8,000 samples are underway to:
- Extend recent and historical auger grids to gain full regional coverage across Antino at 400 m line spacing with 50 m sample spacing along lines
- Infill regional coverage at 200 m line spacing over areas of historical auger gold anomalies and where mapping/prospecting work identified quartz veining and shearing at surface
- Construct targeted 100 m line spaced grids over the Maria Geralda, Van Gogh, and Da Vinci gold trends (in progress). These more tightly spaced grids provide higher resolution geochemical data over regional-scale structures linked to Antino gold mineralization.
Airborne Geophysics
Founders has engaged Expert Geophysics Surveys Inc. to conduct a coincident airborne time-domain electromagnetic (EM) and magnetics survey at 100 m line spacing across the entire Project (Figure 3). The helicopter flown TargetEM26 system employed will deliver high resolution 3D conductivity-resistivity and magnetics data to up to 300 m vertical depth below surface. This system is widely recognized for its effectiveness in similar geologic terranes where it is known to successfully delineate key geological features associated with gold mineralization such as major faults, fold patterns, and the presence of intrusive complexes. These high-resolution datasets will aid in drill targeting on Founders’ intermediate and emerging target areas as well as give new insights into areas that, to date, remain completely unexplored. Founders expects preliminary data from these surveys by mid Q4.
Ongoing Work at Antino
Founders Metals continues to aggressively advance drilling at Antino, with four drills turning: two drills at Upper Antino, one newly arrived drill at Parbo, and one drill at Maria Geralda. Current work includes:
- Continued drilling at Upper Antino to extend gold mineralization along strike and between Froyo and Donut
- Maiden 2,000 m drill program now underway at the Parbo target
- Increased drill program at Maria Geralda following up on initial results in MG003 of 22.5 m of 11.88 grams per tonne (g/t) gold (Au) and subsequent 1,300 m long auger gold anomaly
- Ongoing trenching, mapping, and prospecting to provide structural context for the second phase of drilling across high-priority targets including Van Gogh, Da Vinci, and Lawa during this dry season

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.
