RIDGELINE MINERALS PROVIDES EXPLORATION UPDATE FOR THE SELENA CRD PROJECT, NEVADA

Ridgeline Minerals Corp. has provided an update for the continuing magnetotellurics geophysical survey being completed at the Selena carbonate replacement project, currently being operated by Ridgeline under phase 1 of the exploration earn-in agreement with a wholly owned subsidiary of South32 Ltd.

The MT survey has been designed to cover all high-priority CRD targets at Selena to test for conductive anomalies (that is, sulphide mineralization) at depth, particularly at the Chinchilla sulphide and Skarn targets. The MT contract has been awarded to Moombarriga Geoscience, an Australian-based service provider specializing in MT data collection and processing. The survey is composed of 211 survey stations collected on a 200-metre-by-400-metre grid pattern, with potential to infill the grid pattern as needed. The survey was initiated in early November, and is currently on budget and schedule with an estimated 80 per cent of the survey complete to date.

Mike Harp, Ridgeline's vice-president, exploration, commented: "Completion of this MT survey is a critical first step in advancing the Chinchilla sulphide and Skarn targets to a drill program in 2025. Ridgeline drilled a single drill hole at Chinchilla sulphide in 2022 that returned high-grade CRD mineralization in the same host horizon as the outcropping Chinchilla oxide discovery located 2.5 kilometres to the east. However, this hole did not fully test the target horizon at depth, with the hole ending at 670 metres in low-grade CRD alteration and mineralization after hitting the maximum depth capability of the drill rig."

Mr. Harp continued: "The 2025 drill program is expected to drill to depths exceeding 1,000 vertical metres, and the inclusion of the MT data into our geological model will allow us to more efficiently target the highest-priority zones. We have a high degree of confidence in this survey method as South32 has already utilized MT geophysics at its Hermosa carbonate replacement deposit in Arizona. This approach has been proven effective in identifying and interpreting mineralized trends at Hermosa, and we look forward to applying the same systematic approach to exploration at Selena."

Earn-in terms: South32 retains the right to earn an initial 60-per-cent interest in the Selena project (see Aug. 22, 2024, press release) by financing a minimum of $10-million (U.S.) in qualifying work expenditures on the project over an initial five-year term. South32 retains the option to increase its interest in the project to 80 per cent by financing an additional $10-million (U.S.) in qualifying work expenditures over an additional three-year term. During the phase 2 earn-in period, South32 has the option to take over operatorship of the project. Upon completion of the phase 2 earn-in ($20-million (U.S.) in total expenditures), South32 will provide or arrange for third party financing of Ridgeline's portion of debt financing (20 per cent pro rata) required for the development of the project through to commencement of commercial production.

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.

Technical information contained in this news release has been reviewed and approved by Michael T. Harp, CPG, the company's vice-president, exploration, who is Ridgeline's qualified person under National Instrument 43-101 and responsible for technical matters of this release.
