Founders completes sampling at Maria Geralda, Parbo

Executive Summary
- Founders Metals reports extensive surface sampling results from the Maria Geralda and Parbo targets, highlighting high‑grade anomalous auger samples up to 7.47 g/t Au and 51.42 g/t Au respectively.
- The company confirms a 1.3 km strike length of anomalous material at Maria Geralda and a newly discovered 15 m wide oxidized shear zone at Parbo, supporting the rollout of Phase‑2 drilling at Maria Geralda and upcoming Phase‑1 diamond drilling at both targets in Q4.
- Exploration strategy continues to focus on high‑grade prospects (Van Gogh, Da Vinci, Lawa) and structural extension of known mineralization across Upper/Lower Antino, positioning the project for further bulk‑tonnage and high‑grade drill testing.
Key Details
- Maria Geralda Target
- 1.3 km strike length of anomalous auger samples; grades up to 7.47 g/t Au.
- Total of 516 auger samples, with 314 (61 %) anomalous (>0.02 g/t Au) and 25 % >0.1 g/t Au.
-
Ongoing sampling to test southeastern extension toward Van Gogh.
-
Parbo Target
- Historical auger anomaly (1,200 × 600 m) with samples up to 51.42 g/t Au.
- 1,344 historical auger samples; 83 % anomalous, 46 % >0.1 g/t Au.
- New surface discovery: 15 m wide oxidized shear zone with grab samples up to 26.85 g/t Au.
-
Historical trenching: 49.0 m of 1.02 g/t Au; limited drilling intersected 12.0 m of 3.36 g/t Au.
-
Geological Context
- Targets lie within structures associated with the central Guiana shear zone, a primary control on gold mineralization in the region.
-
Maria Geralda exhibits two styles: high‑grade shear‑hosted mineralization at rock contacts and lower‑grade bulk‑tonnage within intrusions.
-
Next Steps / Drilling Plans
- Continue systematic drilling at Maria Geralda (results pending).
- Complete auger program at Parbo ahead of a Phase‑1 diamond drill program in Q4 2026.
-
Surface programs to provide structural context for Phase‑2 drilling at Van Gogh, Da Vinci and Lawa.
