Ridgeline Minerals Samples up to 9.6 g/t Gold and 0.4% Copper at the Big Blue Porphyry Project, Nevada

• NOI exploration permit approved for up to 38 drill sites
• IP Geophysics survey scheduled for summer 2024

Vancouver, June 27, 2024 - Ridgeline Minerals Corp. (TSXV: RDG) (OTCQB: RDGMF) (FSE: 0GC0) ("Ridgeline" or the "Company") is pleased to announce additional high-grade surface rock chip results at the Big Blue ("Big Blue") porphyry copper ("Cu") - gold ("Au") - silver ("Ag") project in Elko County, Nevada. The sampling was completed by Ridgeline's technical team during reconnaissance prospecting and mapping at a high priority porphyry target located approximately three kilometers ("km") to the west of the Delker Mine, which historically produced 94,434 pounds of copper at an average grade of 6.2% Cu between 1916-1917 ¹ (Figure 1). Both porphyry targets, as originally defined by historic magnetic surveys are largely beneath shallow alluvial cover and future drill targeting will benefit greatly from the upcoming induced polarization ("IP") survey scheduled to begin this summer.

Michael Harp, Ridgeline's Vice President, Exploration commented, "Today's rock chip results continue to validate our exploration model at Big Blue, which projects at least two potential porphyry centers under shallow alluvial cover. We are also seeing an increase in gold grades to the west, where highlight samples returning up to 9.6 g/t gold represent the highest-grade gold values ever sampled on the project. Our IP geophysics program this summer has been designed to test for chargeability anomalies at depth across both porphyry targets and we eagerly anticipate the commencement of the survey in late July."

Surface Sampling Highlights:

• New Porphyry Target: 0.44% Cu, 9.56 grams per tonne ("g/t") Au, 0.30 g/t Ag and 0.25% Cu, 0.10 g/t Au, and 0.20 g/t Ag from two chip samples taken from separate outcropping quartz veins (Figure 1)

• The presence of highly elevated molybdenum ("Mo") values (average of 220.5 parts per million ("ppm") Mo) in the two rock chips taken at this new porphyry target compared to 94 rock chips in the Delker Mine area (average of 10.0 ppm Mo) suggests the porphyry system may be vectoring towards the west
• Additional surface sampling and mapping required in this area

• Previously reported rock chips at the Delker Mine and Skarn Hill porphyry & skarn targets include:

• Delker Mine: 10.80% Cu, 0.10 g/t Au, 4.51 g/t Ag and 4.88% Cu, 0.10 g/t Au, below detection limit ("BDL") Ag (Figure 1 & Picture 1)
• Skarn Hill: 6.44% Cu, 0.16 g/t Au, 53.75 g/t Ag (Figure 1)

• A total of 94 rock chips have been collected between Ridgeline and historical operators. Sample values range from BDL to 10.80% Cu, BDL to 9.56 g/t Au and BDL to 53.75 g/t Ag (avg. 0.96% Cu, 0.02 g/t Au, 1.52 g/t Ag)

Notice of Intent Exploration Permit

• The Company holds an active 5-acre Notice of Intent ("NOI") exploration permit at the project which is currently bonded for 4.92 acres of disturbance totaling 38 drill sites and approximately 4,888 linear feet of access roads (Figure 2)
  • Less than 0.1 acres has been disturbed to-date and the aforementioned permit may be amended with 30 days written notice to the BLM to revise or add additional drill sites and roads as needed

Big Blue Project
Big Blue is located in Elko County, Nevada, approximately seventy-five kilometers ("km") southeast of the city of Elko, NV. The Project includes the past producing Delker Mine, which produced a reported 94,434 pounds of copper at an average grade of 6.2% Cu between 1916-1917 ¹ and shares its southern boundary with Reyna Silver's Medicine Springs Ag-Pb-Zn Carbonate Replacement ("CRD") project. Mineralization occurs as outcropping, high-grade Cu occurrences located proximal to northeast trending felsic dikes that are interpreted as the zoned manifestations off a potential porphyry source, located in the northwest corner of the Big Blue property. Importantly, this target has never been drill-tested. The primary target at Big Blue is porphyry-skarn Cu ± Au-Ag mineralization, with potential to discover polymetallic, carbonate replacement deposit (CRD) style mineralization as the system zones outward over 6 kilometers of strike towards the Medicine Springs project. This target model is analogous to the Butte Valley porphyry Cu-Au system, which is inferred to be the source of CRD mineralization at the Company's nearby Selena project. Big Blue is 100% owned by the Company and is comprised of a total of 41 square kilometers of highly prospective exploration ground that has seen limited exploration since the early 1900's and will benefit from Ridgeline's systematic approach to discovery (view Ridgeline's Corporate Deck HERE).

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