Vancouver, British Columbia--(Newsfile Corp. - September 5, 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 of up to

3.9 percent ("%") copper ("Cu") and

16.3

grams per tonne ("g/t") gold ("Au"), with visible gold ("VG")

noted in the same quartz veins hosting

high-grade Au mineralization (

Figure 1

&

Picture 1

) at the Big Blue ("Big Blue") porphyry Cu-Au project

in Elko County, Nevada.

Sampling was completed by Ridgeline's technical team with the highlight rock chips taken from a

recently identified historical prospect pit located approximately 300 meters ("m") west of the high-grade

Cu-Au rock chips announced on June 27, 2024 (see press release

HERE

).

The Company has since

staked an additional 111 lode claims totaling 2,293 acres to fully encompass the proposed porphyry

target on the west side of the property (

Figure 2

), which will be referred to as the "Ohio" target moving

forward. The combined Big Blue property now totals 602 lode claims totaling 12,463 acres (~50 square

kilometers).

Michael Harp, Ridgeline's Vice President, Exploration commented, "Today's rock chip results

represent the highest-grade gold samples at the Big Blue project to-date, with visible gold noted in our

highlight rock chip sample. Between the Delker Mine and Ohio targets we have defined a kilometer-

scale porphyry Cu-Au footprint that exhibits increasing gold and molybdenum grades towards the

Ohio target, which suggests a potential vector to the porphyry system to the west. Our IP geophysics

survey is now complete and preliminary results indicate the potential for coincident chargeability

anomalies at both porphyry targets, we eagerly anticipate the final IP results over the coming weeks."

Surface Sampling Highlights:

Ohio Target:

3.9% Cu, 16.3 g/t Au, 0.03 g/t silver ("Ag")

(see VG in

Picture 1

)

and 0.1% Cu,

0.01 g/t Au, 0.1 g/t Ag, from two rock chip samples taken from separate quartz veins located in an

outcropping historical prospect pit

June 27, 2024, press release

: 0.44% Cu, 9.56 g/t Au, 0.30 g/t Ag

and 0.25% Cu, 0.10 g/t

Au, 0.20 g/t Ag from two rock chip samples taken from two separate prospect pits with

outcropping quartz veins

The presence of highly elevated molybdenum ("Mo") values in the four rock chips taken at the

Ohio target (average of 219.6 parts per million ("ppm") Mo) compared to 112 rock chips in

the Delker Mine area (average of 9.9 ppm Mo) continues to support the Company's

interpretation that the porphyry system may be vectoring towards the west

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, BDL Ag

(

Figure 1

&

Picture 2

)

Skarn Hill:

6.44% Cu, 0.16 g/t Au, 53.75 g/t Ag

A total of 116 surface rock chips have been collected between Ridgeline and historical operators.

Sample values range from Below Detection Limit ("BDL") to 15.49% Cu, BDL to 16.3 g/t Au and

BDL to 53.75 g/t Ag (avg. 0.96% Cu, 0.28 g/t Au, 1.47 g/t Ag)

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.

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 historically produced

94,434 pounds of copper at an average grade of 6.2% between 1916-1917

1

from structurally controlled

skarn deposits outcropping between the Delker Mine and Skarn Hill Adit. The property shares its

southern boundary with Reyna Silver's Medicine Springs Ag-Pb-Zn Carbonate Replacement ("CRD")

project and had seen limited modern exploration in over a century until Ridgeline staked the property in

2023. The primary target at Big Blue is porphyry-skarn Cu-Au ± Ag-Mo 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 50 square kilometers of highly prospective exploration ground that will benefit

from Ridgeline's systematic approach to discovery (view Ridgeline's Corporate Deck

HERE

).
