Ridgeline Minerals posts more assays for Chinchilla Sulfide CRD discovery at the Selena Project, Nevada

Ridgeline Minerals Corp. [TSXV: RDG; OTCQB: RDGMF; FSE: 0GC0] reported additional assay results from the Chinchilla Sulfide CRD discovery at the Selena Project, Nevada.

Core hole SE25-054 was a 700-metre step-out northeast of discovery hole SE25-053 and intersected an “upper” oxide mineralized intercept of 3.1 metres grading 86.5 g/t silver, 0.3% zinc, 3.8% lead, 2.9 g/t gold, and 0.07% antimony (353.1 g/t AgEq or 14.7% ZnEq) starting at 639 metres downhole. The drillhole was paused at a depth of 916 metres in mid-December due to winter weather constraints and the company anticipates re-entering and continuing the hole in the spring to a target depth of up to 1,200 metres to ensure the hole fully tests the MT target anomaly.

Chad Peters, Ridgeline’s President, CEO & Director commented, “Our 2025 drill program has intersected high-grade CRD mineralization in two of three holes with individual samples grading up to 379 g/t silver, 27% zinc and 2.9 g/t gold. We are very encouraged with the results of the first phase of drilling, and we anticipate a big year ahead now that we have a stronger understanding of the structural controls on mineralization at the Chinchilla Sulfide discovery. Drill planning is in progress, and we anticipate our fully funded 2026 drill program to begin in May.”

Chinchilla Sulfide Zone – Discovery Highlights: SE25-054: 3.1 metres grading 86.5 g/t Ag, 0.3% Zn, 3.8% Pb, 2.9 g/t Au, and 0.07% Sb (353.1 g/t AgEq or 14.7% ZnEq) starting at 639 metres downhole, true thickness unknown.

Hole 54 intersected the faulted and mineralized lower section of what equates to the same host horizon as the Chinchilla Oxide zone that outcrops ~2.5km to the east.

Drilling did not fully test the same lower Chinchilla Sulfide horizon that was intersected in hole SE25-053. The hole was paused in prospective carbonate host rocks and the company intends on completing additional geophysics this spring followed by deepening of hole 54 during the 2026 drill program.

SE25-053: 1.1 metres grading 60.1 g/t Ag, 27.1% Zn, 0.7% Pb, 1.5 g/t Au, 0.4% Cu, and 0.03% Sb (766.4 g/t AgEq or 31.9% ZnEq) starting at 943 metres downhole, true thickness unknown and 17.4 metres grading 35.6 g/t Ag, 6.0% Zn, 0.5% Pb, 0.2 g/t Au, 0.1% Cu, and 0.1% Sb (219.9 g/t AgEq or 9.2% ZnEq), including: 8.6 metres grading 21.1 g/t Ag, 10.4% Zn, 0.3% Pb, 0.1 g/t Au, 0.1% Cu, and 0.1% Sb (273.6 g/t AgEq or 11.4% ZnEq) and 8.7 metres grading 13.9 g/t Ag, 7.0% Zn, 0.3% Pb, 0.1 g/t Au, 0.1% Cu, and 0.01% Sb (175.5 g/t AgEq or 7.3% ZnEq).

The company intends on completing two borehole electromagnetic (BHEM) surveys at the start of the 2026 drill campaign on hole SE25-053 and SE25-054.

The BHEM survey will detect conductive anomalies such as the massive sulfide zones intercepted in SE25-053 and can detect conductive anomalies up to 250m outside of the borehole, which will improve drill targeting and geologic modeling within the survey areas

This method is especially effective for detecting massive sulfide deposits and is commonly used in CRD, VMS and magmatic nickel sulfide exploration.

The project is currently operated by Ridgeline under Phase 1 of an earn-in agreement with a wholly owned subsidiary of South32 Limited, whereby South32 may earn up to an 80% interest in the project by satisfying all commitments under the earn-in agreement.

South32 retains the right to earn an initial 60% interest in the Selena project by funding a minimum of US$10 million in qualifying work expenditures on the Project over an initial five-year term, following which South32 will have a further option to increase its interest in the Project to a total of 80% by funding an additional US$10 million in qualifying work expenditures (for an aggregate spend of US$20 million) over an additional three-year term. If South32 wishes to exercise the Phase 2 option, it must arrange for and provide draft definitive documentation in respect of a debt facility from which (if executed) Ridgeline may draw on to sufficiently fund Ridgeline’s share of costs (20% pro-rata) associated with development of a mine at Selena through to commercial production.

Selena is located in White Pine County, Nevada, approximately 64 km north of the town of Ely, Nevada. The project is currently being operated by Ridgeline under Phase 1 of an earn-in agreement with a wholly owned subsidiary of South32 Limited and shares a property boundary with the Butte Valley project, a $33M earn-in agreement between Freeport-McMoRan and the underlying owner, Falcon Butte Minerals. The project is comprised of 39 km2 of prospective exploration ground including Ridgeline’s shallow-oxide Ag-Au ± Pb-Zn Chinchilla Oxide and deeper Chinchilla Sulfide discoveries.

Subsequent drilling has continued to highlight the potential for high-grade CRD type mineralization (Ag-Zn-Pb-Au ± Cu-Sb-W) between Chinchilla Oxide and Freeport-McMoRan’s Butte Valley Cu-Au-Ag-Zn porphyry located directly west of the property.

Ridgeline Minerals is a discovery focused precious and base metal explorer with a proven management team and a 200 km2 exploration portfolio across seven projects in Nevada, USA. The company is a hybrid explorer with a mix of 100%-owned exploration assets (Big Blue, Atlas, Bell Creek & Coyote) as well as two earn-in exploration agreements with Nevada Gold Mines at its Swift and Black Ridge projects and a third earn-in with South32 at its Selena Project.
