Founders Metals Provides Exploration Update on Emerging Targets; Drills 72.0 m of 1.01 g/t Gold at ParboVancouver, British Columbia--(Newsfile Corp. - December 11, 2025) - Founders Metals Inc. (TSXV: FDR) (OTCQX: FDMIF) (FSE: 9DL0) ("Founders" or the "Company") is pleased to announce drill core assay results from its ongoing drill program at the Antino Gold Project ("Antino" or the "Project") in southeastern Suriname (Figure 1). The results include the first phase of drilling at the Parbo target and follow-up drilling at the Da Vinci and Maria Geralda targets - three priority emerging discoveries within the 56,000 hectare (ha) Antino Gold Project.At Parbo, inaugural drilling has outlined broad, intrusion-hosted gold mineralization with internal high-grade shear zones, highlighted by 72.0 metres (m) of 1.01 grams per tonne (g/t) gold (Au) including 4.0 m of 11.97 g/t Au in hole PB003, and 101.0 m of 0.62 g/t Au from surface in hole PB013. At Da Vinci, step-outs continue to extend the shear-hosted gold mineralization, including 19.5 m of 2.31 g/t Au and 22.5 m of 1.38 g/t Au in hole DV016. At Maria Geralda, drilling has now expanded mineralization 400 m southeast of the initial discovery, returning broad intrusion-hosted gold with discrete high-grade zones, including 53.0 m of 0.41 g/t Au in MG006 and 12.0 m of 1.12 g/t Au in MG010, adjacent to the previously reported 22.5 m of 11.88 g/t Au in MG003. Colin Padget, Founders' President & CEO, commented: "These results from Parbo, Da Vinci, and Maria Geralda further demonstrate the scale and consistency of the gold systems emerging across Antino. Parbo, in particular, is shaping up as a significant intrusion-hosted target with multiple shear zones that remain open in all directions. I was especially impressed with Parbo hole PB013 which, including a 10 m interval of dilution, returned 200 m of 0.51 g/t Au from surface. We will continue to advance this exciting target into the new year. Da Vinci and Maria Geralda continue to deliver robust gold mineralized intercepts within increasingly well-defined structural corridors. Each round of drilling strengthens our geological model, guiding a focused, systematic, and value-driven approach as we plan our 2026 exploration program."Drilling HighlightsPARBO - Broad intrusion-hosted gold system with internal high-grade shear zonesPB003: 72.0 m of 1.01 g/t Au from 111.0 m, including 4.0 m of 11.97 g/t AuPB013: 101.0 m of 0.62 g/t Au from surface and 77.0 m of 0.47 g/t Au from 123.0 mPB001: 21.0 m of 0.96 g/t Au from 66.0 m and 12.0 m of 2.91 g/t Au from 262.0 m Drilling confirms substantial gold mineralization across an ~800 m by 400 m corridor down to 250 m vertical depth and remains openCore logging of additional holes pending assay results indicate the intrusive complex, shearing, and sulphide-bearing quartz vein system extends at least 1,400 m by 800 m and to at least 275 m depthVertical auger sampling to depths between 10-15 m demonstrates gold mineralization extends through the oxide zone and to surface, with auger results including 13.0 m of 1.05 g/t Au (PB011) and 13.0 m of 0.79 g/t Au (PB013)DA VINCI - Main zone expansion and discovery of new parallel structure DV016:19.5 m of 2.31 g/t Au from 21.6 m;22.5 m of 1.38 g/t Au from 99.6 m;plus, additional broad shear-hosted intervals of anomalous gold mineralizationDV017: 18.0 m of 0.58 g/t Au and 4.0 m of 1.77 g/t AuDV019: 22.5 m of 0.24 g/t Au in the first hole testing a new parallel structure 1.5 km southwest of Da Vinci with additional holes from this target pending assayRegional auger sampling expands the Da Vinci gold-in-auger anomaly >1.0 km southeast, while mapping, LiDAR, and magnetics collectively define a >2.5 km structural trend linking Da Vinci to BueseMARIA GERALDA - 400 metre strike extension from discovery hole and broad intrusive-hosted mineralizationMG006: 53.0 m of 0.41 g/t Au and 17.0 m of 0.31 g/t AuMG009: 3.0 m of 2.03 g/t Au and 22.5 m of 0.34 g/t AuMG010: 12.0 m of 1.12 g/t Au, 2.0 m of 5.12 g/t Au, and 3.0 m of 1.71 g/t Au, plus additional mineralized intervals (see table 1)Drilling extends the mineralized trend 400 m southeast, for a total of over 600 m of drill-confirmed gold-mineralized strikeAuger sampling extends the surface anomaly a further 950 m southeast towards the Van Gogh target, bringing the total length of surface anomaly to 2 km. Geological DiscussionPARBOParbo is defined by a 1.2 km × 0.6 km historical gold-in-auger anomaly with local 1 m auger samples grading up to 51.42 g/t Au*. Founders' Phase 1 drilling targeted mapped intrusive contacts and shear zones to successfully confirm broad, continuous zones of gold mineralization within a granodiorite intrusive body. The current drill-defined mineralized corridor measures ~800 m × 400 m and down to ~250 m depth, remaining open in all directions. Geological logging from recent step-outs suggests the broader intrusive complex extends at least 1.4 km × 0.8 km and to ~275 m vertical dept
