Vancouver, British Columbia--(Newsfile Corp. - May 14, 2026) - Ridgeline Minerals Corp. (TSXV: RDG) (OTCQB: RDGMF) (FSE: 0GC0) ("Ridgeline" or the "Company") is pleased to announce the initiation of the Company's 2026 partner-funded drill program at the Chinchilla Sulfide Carbonate Replacement ("CRD") discovery at the Selena ("Selena") project. Drilling will take a phased approach in 2026 with the program starting with three deep holes targeting the Chinchilla Sulfide discovery (Figure 1 & Picture 1) SE26-055 is a 250m step-out to the northeast of 2025 discovery hole SE25-053 which intersected multiple lenses of massive sulfide CRD style mineralization ranging from 1.1 - 17.4m thick including highlight intercepts of 1.1m grading 27.0% Zn, 60.1 g/t Ag, 0.7% Pb, 1.5 g/t Au, 0.4% Cu, 0.03% Sb (766.4 g/t AgEq or 31.9% ZnEq) starting at 943m downhole, true thickness unknown And: 17.4 meters grading 6.0% Zn, 35.6 g/t Ag, 0.5% Pb, 0.2 g/t Au, 0.1% Cu, 0.1% Sb (219.9 g/t AgEq or 9.2% ZnEq) (Figure 1) And: 8.7 meters grading 7.0% Zn, 13.9 g/t Ag, 0.3% Pb, 0.1 g/t Au, 0.1% Cu, 0.01% Sb (175.5 g/t AgEq or 7.3% ZnEq) (See December 18, 2025 PR HERE) SE26-056 will test between SE25-053 and the Company's 2022 RC drillhole SE22-038 that intercepted 1.5m grading 97.4 g/t Ag, 4.9% Zn, 0.1% Pb and 0.4 g/t Au in the same oxide upper horizon as SE25-054 (see March 16, 2026 PR HERE) but did not drill deep enough to test the projection of the same sulfide CRD horizon that was intercepted in SE25-053 (Figure 1) SE26-057 will test a new target concept adjacent to the Butte Valley Cu-Au-Ag-Zn porphyry system with the goal of intersecting copper-silver enriched skarn mineralization that is projected along the margins of the Butte Valley porphyry (Figure 1) Borehole electromagnetic ("BHEM") surveys will be completed in early-mid June in holes SE25-053 and SE25-054 to assist in the 3D modelling of conductive sulphide-rich zones at depth and laterally from the drill holes.
