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, British Columbia--(Newsfile Corp. - 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

).

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.
