Ridgeline Minerals (OTCQB: RDGMF) announced a new high-grade carbonate-replacement (CRD) massive sulfide discovery at the Chinchilla Sulfide target, Selena project, Nevada, from hole SE25-053 on November 4, 2025. Key assays include 1.1m @ 27.0% Zn, 60.1 g/t Ag, 1.5 g/t Au and 8.6m @ 10.4% Zn, 21.1 g/t Ag, within broader 17.4m @ 6.0% Zn, 35.6 g/t Ag. Multiple massive sulfide horizons (0.5–17.4m) were intersected in Guilmette Limestone; additional deeper assays are pending. The project is under a South32 earn-in where South32 can fund up to US$20M to earn up to an 80% interest.

Ridgeline Minerals (OTCQB: RDGMF) has announced the grant of equity-based compensation to company insiders and employees. The company has issued 1,955,000 stock options exercisable at $0.24 per share with a five-year term.

Ridgeline Minerals (OTCQB: RDGMF) provided updates on drilling programs at its three partner projects in Nevada: Swift, Black Ridge, and Selena. The company has secured its largest exploration budget to date of US $9.5 million through partner funding, with assays pending through Q4 2025 and Q1 2026.

The Selena project, operated by Ridgeline under a US $20 million South32 earn-in agreement, is progressing with a US $3.45 million budget for up to three deep core holes. The Swift project, under a US $30 million NGM earn-in agreement, is testing high-grade gold intercepts with up to five planned holes. At Black Ridge, under a US $10 million NGM earn-in agreement, one deep core hole was completed in August with results expected in Q4 2025.

Ridgeline Minerals (OTCQB: RDGMF) has announced results from its maiden drill program at the Atlas project in Nevada. The program completed two core holes totaling 551 meters in the northern section of the Atlas property, targeting Pennsylvanian to Permian age host rocks.

Key highlights include hole AT25-001 intersecting 0.2m grading 1.80 g/t gold within 8.5m grading 0.20 g/t Au, and AT25-002 returning 5.9m grading 0.20 g/t Au. Both holes exhibited continuous Carlin-Type alteration and mineralization, with AT25-001 showing 298 meters of continuous mineralization and high-grade silver intercepts up to 75.1 g/t Ag.

The company interprets these results as intersecting a low-grade gold and trace element halo typically associated with Carlin-Type gold deposits' outer margins. Ridgeline plans to continue land consolidation and field work throughout 2025, with a Phase II drill program planned for 2026.

Midasco Capital Corp. (TSXV: MGC-H) has completed the acquisition of Spartan Exploration Nevada Corporation from Ridgeline Minerals Corp. (TSXV: RDG) (OTCQB: RDGMF). The acquisition includes the Eagle Property in Nevada, comprising 244 lode mineral claims with significant tungsten-copper deposits. The property historically produced 8,352 tonnes of tungsten trioxide at grades of 0.6-1.0% between 1917-1956.

As part of the deal, Midasco issued 5,830,466 shares to Ridgeline (19.9% ownership) and will issue additional shares on the one-year anniversary. Ridgeline also received a 1% net smelter return royalty. Midasco has changed its name to Spartan Metals Corp. and will trade under the symbol "W" starting August 5, 2025.

Ridgeline Minerals (OTCQB: RDGMF) has launched a significant 6,000-meter drill program at its Swift gold project in Nevada, operated under an exploration agreement with Nevada Gold Mines (NGM). The program is backed by NGM's US$5 million exploration budget for 2025, building on successful 2024 results that included high-grade gold intercepts of 10.4 g/t Au over 1.1 meters.

The program includes five planned drill holes, with four targeting the SW Swift area and one testing the Mill Creek target. NGM has invested US$10.87 million in the project through June 2025 and must spend US$20 million by December 2026 to earn a 60% interest, with options to increase ownership to 75% through additional investments and development financing.

Ridgeline Minerals (OTCQB: RDGMF) has issued a correction notice regarding its upcoming annual general meeting (AGM). The company identified and corrected a typographical error in the AGM materials concerning the record date, which is confirmed as July 3, 2025.

Shareholders can access the amended AGM materials through SEDAR+ and the company's website.

Ridgeline Minerals (OTCQB: RDGMF) has reported results from maiden drilling programs at its 100%-owned Big Blue and Atlas projects in Nevada. At Big Blue, hole BB25-003 intercepted high-grade mineralization of 0.7% Cu, 3,194 g/t Ag and 2.6% W over 0.6 meters (35.3% copper equivalent) at 675.7m depth. The program completed three core holes totaling 2,072 meters targeting the Delker Mine area.

The Delker porphyry target drilling revealed a pre-mineral intrusion without significant copper values. At Atlas, two core holes totaling 551 meters were completed, intersecting anticipated Penn/Perm host rocks with Carlin-Type alteration and oxide mineralization to depths of approximately 200m vertical. Assay results for Atlas are pending.

Ridgeline Minerals has initiated its 2025 drill program at the Selena Carbonate Replacement project in Nevada, operating under Phase 1 of an earn-in agreement with South32. South32 has approved a $3.45 million Year-2 exploration budget to drill up to three deep core holes, totaling 4,500 meters, targeting a highly conductive Magnetotellurics anomaly at the Chinchilla Sulfide CRD target. The drilling program will test specific stratigraphic and structural horizons across the known strike of the MT anomaly, with the first hole targeting the shallowest expression of the Chinchilla Sulfide target. The anomaly plunges approximately 45 degrees north to south and is bounded by east verging thrust faults, which are interpreted as key fluid conduits to the CRD system. The Selena Project, located 64 kilometers north of Ely, Nevada, shares a property boundary with the Butte Valley project and comprises 39 square kilometers of exploration ground.
