RIDGELINE MINERALS COMMENCES DRILL PROGRAM AT THE SELENA CRD PROJECT, NEVADA

Ridgeline Minerals Corp. has commenced its 2025 drill program at the Selena carbonate replacement project. The project is currently being operated by Ridgeline under phase 1 of an earn-in agreement with a wholly owned subsidiary of South32 Ltd. All dollars noted are U.S. dollars.

South32 has approved a year two exploration budget of $3.45-million to drill up to three deep core holes (4,500 metres total) targeting the highly conductive magnetotellurics anomaly that was identified at the Chinchilla sulphide carbonate replacement deposit target in early 2025. All three core holes will target specific stratigraphic and structural horizons across the known strike of the MT anomaly, with the first of three holes targeting the shallowest expression of the Chinchilla sulphide target. The anomaly plunges roughly 45 degrees north to south and is bound on both sides by a series of east-verging thrust faults, interpreted as key fluid conduits to the CRD system.

Quality assurance/quality control procedures

Samples are submitted to American Assay Laboratories of Sparks, Nev., which is a certified and accredited laboratory, independent of the company. Independent check samples are sent to Paragon Geochemical Labs of Sparks, Nev. Samples are prepared using industry-standard prep methods and analyzed using FA-PB30-ICP (gold, 30-gram fire assay) and ICP-5AM48 (48-element suite, 0.5-gram five-acid digestion/ICP-MS) methods. AAL also undertakes its own internal coarse and pulp duplicate analysis to ensure proper sample preparation and equipment calibration. Ridgeline's QA/QC program includes regular insertion of CRM standards, duplicates and blanks into the sample stream with a stringent review of all results completed by the company's qualified person, Michael T. Harp, vice-president, exploration.

Selena project

Selena is located in White Pine county, Nevada, approximately 64 kilometres north of the town of Ely, Nev. The project is currently being operated by Ridgeline under phase 1 of an earn-in agreement with a wholly owned subsidiary of South32 Ltd. and shares a property boundary with the Butte Valley project, a $33-million earn-in agreement between Freeport-McMoRan and the underlying owner, Falcon Butte Minerals. The project is composed of 39 square kilometres of highly prospective exploration ground, including Ridgeline's shallow-oxide silver-gold plus or minus lead-zinc Chinchilla oxide and deeper Chinchilla sulphide discoveries. Subsequent drilling has continued to highlight the potential for high-grade CRD type mineralization (silver-gold-lead-zinc plus or minus copper-tungsten) between Chinchilla oxide and Freeport-McMoRan's Butte Valley copper-gold-silver-zinc porphyry located directly west of the property. For additional information regarding the South32 earn-in agreement terms, view the Aug. 22, 2024, news release.
