Vancouver, British Columbia--(Newsfile Corp. - December 11, 2025) - Ridgeline Minerals Corp. (TSXV: RDG) (OTCQB: RDGMF) (FSE: 0GC0) ("Ridgeline" or the "Company") is pleased to provide assay results for the Black Ridge Project ("Black Ridge") and an exploration update for the drill program at the Swift Project ("Swift") located on the Carlin and Cortez mine trends in north-central Nevada (Figure 1). Swift and Black Ridge are operated by Nevada Gold Mines ("NGM") and are both in Phase 1 of separate exploration earn-in agreements totaling US $40,000,000 in potential earn-in expenditures. Details for each program are highlighted below.
Chad Peters, Ridgeline's President, CEO & Director commented, "We are very encouraged by the Nevada Gold Mines teams first drill hole at Black Ridge, which has validated our Lower Plate target concept and confirms that gold mineralization continues along the Leeville Trend and extends onto the Black Ridge property at shallower than modeled depths. The anomalous gold and Carlin-Type alteration was intersected within the same host rocks as NGM's neighbouring Leeville Mine and Fallon gold deposit, highlighting the exploration potential at Black Ridge. Further drilling is required to vector into higher-grade gold mineralization along this highly prospective fault corridor."
Mr. Peters continues, "Assays are pending for two deep core holes at our Swift project, with drilling following up on the success of last year's drill program, which delivered the first high-grade gold intercepts ever drilled at the SW Swift target. We originally anticipated results from our first hole in November; however, NGM is experiencing lab delays due to the high volume of samples from the Fourmile project. We have recently received confirmation that our samples are now being processed, and we look forward to releasing assay results as soon as they are available."
Black Ridge Project (US $10,000,000 NGM Earn-in)
NGM completed one deep core hole to a depth of 1,109 meters ("m") in August with the primary goal of testing the same lower-plate host rock section that host NGM's currently producing Leeville Mine and high-grade Fallon discovery, both of which are located on-trend of and approximately 3.0 kilometers to the southwest of Black Ridge (Figure 2).
- Drilling intersected Lower Plate Rodeo Creek formation (Drc) host rocks at 773 m vertical depth, which is substantially shallower than anticipated based on Ridgeline's 2020 drill campaign.
- The hole transitioned from Rodeo Creek into a 6.7m thick section of Popovich formation (Dp), which is thinner than usual and interpreted as a potentially faulted off section of Dp (Figure 3).
- The entire section of Dp exhibited extensive silicification, crackle brecciation and sulfidation with elevated Carlin-Type pathfinders (As-Sb-Hg) throughout.
- Returned a highlight intercept of 0.8m grading 0.113 g/t gold starting at 972.8 m in sulfidized Popovich formation (Picture 1). True widths of the drilled intercept are unknown at this time.
- The hole bottomed in variably altered and bleached Bootstrap Formation (SDb), which is the host to multiple past and currently producing gold deposits on the Carlin Trend .
NGM has incurred a total of US $1,071,000 in qualifying work expenditures at the Project through November 30, 2025, and NGM must spend a minimum of US $4,500,000 in qualifying work expenditures by July 14, 2028, to earn an initial 60% interest in the Project (see July 17, 2023 press release HERE).
Swift Project (US $30,000,000 NGM Earn-in)
The second core tail out of the five proposed holes in 2025 is complete with assays pending on both. An additional RC pre-collar has been completed to depth of 730 m and drilling is in progress on a second. Both will be ready for re-entry in the spring of 2026 to continue drilling along strike of previous high-grade gold intercepts (up to 1.1m grading 10.4 g/t Au in SW24-006) at the SW Swift target (Figure 4).
NGM has incurred a total of US $14,789,000 in qualifying work expenditures at the Project through September 30, 2025, and must spend a minimum of US $20,000,000 in qualifying work expenditures by December 31, 2026, to earn an initial 60% interest in the Project (see September 22, 2021 press release HERE).

QAQC Procedures
Swift and Black Ridge samples are submitted to ALS Minerals, Elko Nevada, which is a certified and accredited laboratory, independent of Nevada Gold Mines. Drill core samples consist of both HQ and NQ size core which is split using a diamond core saw with 1/2 of the cut core sample submitted for assay and the remaining 1/2 core sample retained in the core box for future reference. Samples are prepared using industry-standard prep methods and analysed using Au-AA23 (Au; 30 g fire assay) and ME-MS61 (48 element Suite; 0.25 g 4-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 QAQC 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.
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. Mr. Harp has reviewed Nevada Gold Mines' internal QAQC program and has confirmed that it meets or exceeds best practice standards. Mr. Harp is a "qualified person" under National Instrument 43-101 - Standards of Disclosure for Mineral Projects.
