RIDGELINE MINERALS MT SURVEY CONFIRMS HIGH-PRIORITY 2025 DRILL TARGETS AT THE SELENA CRD PROJECT, NEVADA

Ridgeline Minerals Corp. has released the results of the magnetotellurics (MT) geophysical survey completed in late 2024 at the Selena carbonate replacement (CRD) project. The MT survey has identified a strong, kilometre-scale conductive anomaly that suggests the potential for the Chinchilla sulphide target to host a robust silver-(Ag)-gold-(Au)-lead-(Pb)-zinc-(Zn) CRD system at depth. Given these results, budgeting and planning in support of an accelerated 2025 phase 1 drill campaign is currently in progress.

The project is currently being operated by Ridgeline under phase 1 of the earn-in agreement with a wholly owned subsidiary of South32 Ltd. Highlights of the MT survey are detailed below.

Mike Harp, Ridgeline's vice-president, exploration, commented: "The CRD target coming together at Chinchilla sulphide has exceeded our teams' expectations in every way. The scale and intensity of the MT anomaly, combined with two high-grade intercepts drilled by our team in 2022 that tested the edges of the previously unknown MT anomaly now suggests we are vectoring towards a sulphide CRD horizon at depth."

Mr. Harp continues: "Drill planning is in progress for our 2025 program and the inclusion of the MT data into our geological model has allowed us to more efficiently target the highest-priority anomalies at depth. We have a high degree of confidence in the MT interpretation given that our partners at South32 have utilized MT geophysics to identify mineralized CRD trends at the Taylor deposit, part of South32's Hermosa project in Arizona."

MT survey highlights

• Chinchilla sulphide -- Geologically constrained 3-D inversion modeling of the MT survey has identified a large conductive anomaly with dimensions of approximately 1.5 kilometres (km) wide by 600 metres (m) in estimated thickness, and extends for over 2.0 km along strike.
• The core of the MT anomaly ranges from 25.0- to 100.0-ohm metres, which is highly conductive and interpreted as a broad zone of CRD alteration and sulphide mineralization:
  • Reverse circulation (RC) hole SE22-037 (2022 DDH) intersected 3.0 metres grading 40.2 grams per tonne (g/t) Ag, 7.0 per cent Pb-Zn and 3.0 g/t Au (or 605.3 g/t AgEq (silver equivalent)) within 15.3 m grading 12.30 g/t Ag, 1.7 per cent Pb-Zn and 0.8 g/t Au (or 156.3 g/t AgEq) starting at 735 m down hole.
  • RC hole SE22-038 intersected 1.5 m grading 97.4 g/t Ag, 5.0 per cent Pb-Zn and 0.4 g/t Au (or 342.9 g/t AgEq) starting at 765 m down hole.
    • Holes 37 and 38 were drilled on either side of the MT anomaly and were targeting magnetic highs, which are now interpreted as system bounding fault structures.
      • Due to the depth limitations of the RC rig, both holes were stopped directly above the 100 to 250 .m MT contours, which is interpreted as the outer extents of the sulphide CRD horizon.
• Chinchilla oxide -- The MT survey highlights a weakly conductive anomaly (500 to 1,000 .m) that directly correlates with known oxide CRD mineralization.
  • Supports the company's interpretation that shallow oxide mineralization (less conductive) is transitioning to sulphide mineralization (more conductive) at the Chinchilla sulphide target.
• Geologic controls -- The geometry of the Chinchilla sulphide MT anomaly is directly controlled by:
  • East verging thrust faults and northeast striking normal faults.
  • Intersection of the aforementioned structures with reactive carbonate host rocks of the Guilmette, Simonson and Sevy formations, which exceed 500 m in total thickness.

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 funding a minimum of $10-million (U.S.) 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 per cent by funding an additional $10-million (U.S.) in qualifying work expenditures (for an aggregate spend of $20-million (U.S.)) over an additional three-year term. During the phase 2 earn-in period, South32 has the option to take over operatorship of the project. Before exercise of the phase 2 option, South32 will arrange for and provide draft definitive documentation in respect of a debt facility from which (if executed) Ridgeline may draw on to sufficiently finance Ridgeline's share of costs (20-per-cent pro rata) associated with development of a mine at Selena through to commercial production.

QA/QC (quality assurance/quality control) procedures

Samples are submitted to American Assay Laboratories (AAL) of Sparks, Nev., which is a certified and accredited laboratory, independent of the company. Independent check samples are sent to Paragon Geochemical Labs (PAL) of Sparks, Nev. Samples are prepared using industry-standard prep methods and analyzed using FA-PB30-ICP (Au; 30 g fire assay) and ICP-5AM48 (48-element suite; 0.5 g 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.

The technical information contained in this news release has been prepared under the supervision of, and approved by Michael T. Harp, CPG, the company's vice-president, exploration.

Selena project

Selena is located in White Pine county, Nevada, approximately 64 kilometres (km) north of the town of Ely, Nev. The project shares a property boundary with the Butte Valley project, a $33-million (U.S.) earn-in agreement between Freeport-McMoRan and the underlying owner, Falcon Butte Minerals. The 100-per-cent-owned project comprised 39 square kilometres of highly prospective exploration ground including Ridgeline's shallow-oxide Ag-Au plus or minus Pb-Zn Chinchilla oxide and deeper Chinchilla sulphide discoveries. Subsequent drilling has continued to highlight the potential for high-grade CRD type mineralization (Ag-Au-Pb-Zn plus or minus Cu-W) between Chinchilla oxide and Freeport-McMoRan's Butte Valley Cu-Au-Ag-Zn porphyry located directly west of the property.
