RIDGELINE MINERALS ACQUIRES EXTENSIVE HISTORICAL DATABASE FOR THE BIG BLUE PROJECT, NEVADA

Ridgeline Minerals Corp. has acquired, at no cost to the company, an extensive historical exploration database for the Big Blue project from an undisclosed third party. Big Blue is a porphyry-CRD (carbonate replacement deposit), copper (Cu), gold (Au), silver (Ag), lead (Pb) and zinc (Zn) exploration prospect in Elko county, Nevada, which includes the past-producing high-grade copper Delker mine (see Feb. 9, 2023, press release). The newly acquired data are a modern geologic database consisting of detailed mapping, surface geochemistry, drill data, and multiple generations of surface and airborne geophysics. The data have been thoroughly validated and incorporated into the Big Blue geologic model, and is expected to save significant time and exploration capital to advance the project to a maiden drill program in 2024. A detailed summary of the historical database is highlighted below.

Mike Harp, Ridgeline's vice-president, exploration, commented: "The acquisition of this historical dataset is a major step forward for the geologic model at Big Blue and significantly accelerates the exploration process for our team. The geophysical surveys in particular highlight multiple potential targets, including porphyry targets and a well-defined, northeast-trending structural corridor that extends between the historical Delker copper-gold mine and Reyna Silver's Medicine Springs CRD project located on our southwestern boundary. This untested structural trend represents a highly prospective, six-kilometre-long target area that is bracketed on both ends by historical copper and base metal mines. The database also suggests that the limited historical drilling that was conducted on the project did not drill deep enough to adequately test geophysical anomalies located directly beneath multiper-cent-copper mineralization that was historically mined from the Delker mine and Skarn Hill adit. Our team plans on integrating and reinterpreting the raw data sets to continue building out the geologic mode, with the goal of initiating a maiden drill campaign in 2024."

Historical data summary

Geophysics:

• Two generations of magnetic surveys, including a regional airborne survey and high-resolution ground magnetics with a 3-D inversion focused on the Delker mine area;
• Ground gravity survey with supporting 3-D inversion;
• Two induced polarization (IP) lines focused on the Delker mine and Skarn Hill adits;
• Significance -- airborne magnetics and IP lines highlight potential for porphyry source at depth, while ground magnetics and gravity surveys highlight key structural trends.

Surface geochemistry:

• Individual rock chip samples returned up to 5.5 per cent Cu:
  • A total of 61 historical rock chips have been added to the Ridgeline database, ranging from below assay detection limits to 5.5 per cent Cu (average 0.42 per cent Cu).
• 251 soil samples were collected on a 100-metre by 100 m grid within outcrop and shallow alluvium in the Delker mine area;
• Significance -- rock chips confirm roughly 1.5-kilometre-long trend of high-grade Cu-skarn mineralization on-trend of the Delker mine and Skarn Hill adit.

Drilling:

• Six historical drill holes completed by Newmont and Exxon Minerals were drilled on the project for a total of 1,177 metres, with the deepest hole reaching a maximum depth of 1,177.3 metres;
• Significance -- limited drilling on the property did not drill deep enough to test targets within prospective limestone host horizons.

Mapping:

• Multiple generations of detailed geologic mapping between 1989 and 1992;
• Significance -- mapping highlights copper-bearing felsic dikes that crosscut older Jurassic-age porphyries in the Delker mine area.

Geochronology:

• Regional age-dating program highlights up to six generations of Jurassic-age porphyry intrusions with multiple copper-bearing felsic dikes that crosscut the Jurassic intrusions;
• Significance -- Jurassic-age porphyries are the same age range as Nevada's Yerington copper district, with mapped and crosscutting copper-bearing dikes in the Delker mine area suggesting the potential for a Cretaceous-age porphyry system (that is, Robinson copper district)

Big Blue project

Big Blue is located in Elko county, Nevada, approximately 75 km southeast of the city of Elko, Nev. The project includes the past-producing Delker mine, which produced a reported 94,434 pounds of copper at an average grade of 6.2 per cent Cu between 1916 and 1917, and shares its southern boundary with Reyna Silver's Medicine Springs Ag-Pb-Zn carbonate replacement project. Mineralization occurs as high-grade skarn located proximal to northeast-trending felsic dikes that are interpreted as bleeding off a potential porphyry source located on or near the Big Blue property, which has never been drill tested. The primary target at Big Blue is porphyry-skarn Cu plus or minus Au-Ag mineralization, which may be the source of distal CRD mineralization at Medicine Springs -- analogous to the Butte Valley porphyry Cu-Au system inferred to be a source of CRD mineralization at the company's nearby Selena project. A large portion of the project is covered by shallow, postmineral gravels covering a roughly five km target area, resulting in limited surface expression of the porphyry system. The 100-per-cent-owned project is composed of a total of 29 square kilometres of highly prospective exploration ground that has seen limited exploration since the early 1900s and will benefit from the Ridgeline's systematic approach to discovery (view Ridgeline's corporate deck on-line).

Quality assurance/quality control (QA/QC) procedures

Samples are submitted to American Assay Laboratories (AAL) of Sparks, Nev., which is a certified and accredited laboratory, independent of the company. Samples are prepared using industry-standard prep methods, and analyzed using FA-PB30-ICP (Au: 30-gram fire assay) and ICP-5AM48 (48-element suite: 0.5 g five-acid digestion/ICP-MS (inductively coupled plasma mass spectrometry)) 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.

Technical information contained in this news release has been reviewed and approved by Mr. Harp, CPG, the company's vice-president of exploration, who is Ridgeline's qualified person under National Instrument 43-101 and responsible for technical matters of this release.
