RIDGELINE MINERALS PROVIDES DRILL PROGRAM UPDATES FOR ITS THREE PARTNER PROJECTS IN NEVADA

Ridgeline Minerals Corp. has provided exploration updates for continuing drill programs at the Swift, Black Ridge and Selena exploration projects located in north-central Nevada. The Swift and Black Ridge gold projects are operated by Nevada Gold Mines (NGM) and are both in phase 1 of separate exploration earn-in agreements totalling $40-million (U.S.) in potential earn-in expenditures. Ridgeline remains the operator at the Selena CRD (carbonate replacement deposit) project, which is in phase 1 of an earn-in agreement with a wholly owned subsidiary of South32 Ltd. totalling $20-million (U.S.) in potential earn-in expenditures.

The combined partner-financed 2025 exploration budget of $9.5-million (U.S.) represents the largest exploration budget in company history, with assays pending at all three projects through Q4 2025 and into Q1 2026.

Chad Peters, Ridgeline's president, chief executive officer and director, commented: "Drilling is progressing smoothly across our three partner projects, with both Swift and Selena close to finishing up the first deep core tails of their respective programs. NGM has also recently completed a single framework drill hole at Black Ridge, which is on trend of NGM's Leeville mine and Fallon deposit to the south. We expect drilling to continue at Swift and Selena through the end of 2025 with steady news flow and assay results throughout the end of the year."

Selena project ($20-million (U.S.) South32 earn-in)

The drill program at Selena has been in progress since June, with the first core tail commencing in late July. The $3.45-million (U.S.) budget will drill up to three deep core holes (4,500 metres total) targeting the highly conductive magnetotellurics (MT) anomaly that was identified at the Chinchilla sulphide CRD target in early 2025. For a detailed summary of the drill program, see the June 23, 2025, press release.

South32 has incurred a total of $573,758 (U.S.) in qualifying work expenditures at the project through June 30, 2025, and must spend a minimum of $10-million (U.S.) in qualifying work expenditures by Aug. 21, 2029, to earn an initial 60-per-cent interest in the project (see Aug. 22, 2024, press release).

Swift project ($30-million (U.S.) NGM earn-in)

The first of up to five holes is in progress and testing along strike of previous high-grade gold intercepts (up to 1.1 metres grading 10.4 grams per tonne gold in SW24-006) at the projected intersection of crosscutting fault zones (that is, fluid conduits), where they intersect a modelled fold hinge (that is, fluid trap) on the hangingwall side of the Mill Creek thrust. For a detailed summary of the drill program, see the July 30, 2025, press release.

NGM has incurred a total of $10,869,000 (U.S.) in qualifying work expenditures at the project through June 30, 2025, and must spend a minimum of $20-million (U.S.) in qualifying work expenditures by Dec. 31, 2026, to earn an initial 60-per-cent interest in the project (see Sept. 22, 2021, press release).

Black Ridge project ($10-million (U.S.) NGM earn-in)

One deep core hole was completed by NGM in August with the primary goal of testing the same lower-plate host rock section that hosts multiple past and currently producing gold deposits on the north Carlin trend. Samples are being prepared for assay, with results anticipated in Q4, 2025.

NGM has incurred a total of $586,904 (U.S.) in qualifying work expenditures at the project through June 30, 2025, and NGM must spend a minimum of $4.5-million (U.S.) in qualifying work expenditures by July 14, 2028, to earn an initial 60-per-cent interest in the project (see July 17, 2023, press release).

Note: The qualified person has been unable to verify the Fallon and Ren resources and mineralization on nearby properties is not necessarily indicative to the mineralization potential on the Black Ridge property.

Quality assurance/quality control procedures

Selena 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 (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 (certified reference material) 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.

Swift and Black Ridge samples are submitted to ALS Minerals of Elko, Nev., which is a certified and accredited laboratory, independent of Nevada Gold Mines. Samples are prepared using industry-standard prep methods and analyzed using Au-AA23 (gold; 30-gram fire assay) and ME-MS61 (48-element suite; 0.25-gram four-acid digestion/ICP- MS) methods. ALS also undertakes its own internal coarse and pulp duplicate analysis to ensure proper sample preparation and equipment calibration. Nevada Gold Mines' QA/QC program includes regular insertion of CRM standards, duplicates and blanks into the sample stream, with a stringent review of all results completed internally by Nevada Gold Mines technical personnel.
