Ridgeline Minerals Provides Drill Program

Updates for the Big Blue and Atlas Projects

Vancouver, British Columbia--(Newsfile Corp. - May 15, 2025) - Ridgeline Minerals Corp. (TSXV: RDG)

(OTCQB: RDGMF) (FSE: 0GC0) ("

Ridgeline

" or the "

Company

") is pleased to provide updates for

maiden drill programs at the Big Blue and Atlas exploration projects (

Figure 1

). Both projects are 100%-

owned by the Company with no underlying work commitments or royalties. The Big Blue (Porphyry Cu-

Au) drill program is nearing completion after which the core rig will be moved to the Atlas (Carlin-Type

oxide Au) project. Details on each drill program are highlighted below.

Big Blue

The Company completed two deep core holes drilling from the western flank of the Delker Butte mine

trend to test both high-grade Cu-Au skarn and potential porphyry Cu-Au targets at depth

Upon completion of the first two holes, Ridgeline decided to add a third hole drilling back from the

east side of the mine trend (

Figure 2

)

Based on the first two holes, the Company believes drilling from the east side of the Delker

trend will intersect the high-grade Cu-Au skarn target at a more favourable orientation

Hole #3 is expected to be complete over the next 7-10 days with assays for the entire program to

be released together in late June

Atlas

The maiden drill program at Atlas will start with an initial 3-hole (500 meters) program targeting shallow

oxide, Carlin-Type gold mineralization in the north block of the Atlas property, which highlights the

strongest gold in soil and surface rock chip grades across the property (

Figure 3

)

Pending results of the first three holes the Company may decide to expand the program to 5-6

holes

The Company has staked an additional thirteen (13) BLM lode claims to consolidate all available

BLM claims in the South Block of the property

Mike Harp, Ridgeline's Vice President, Exploration commented, "We have encountered some difficult

drill conditions at depth in our third hole at Big Blue, which has put us a few weeks behind schedule.

However, production is back on track, and over the next few weeks we expect to fully test the high-

grade copper skarn target horizon that is the interpreted feeder to the historical copper mines at

surface."

Mike Harp continues "We are excited to get this last hole complete before heading over to Atlas where

we will test the outcropping oxide gold system in the north block, which exhibits many geologic

similarities to the nearby Dark Star deposit, a multi-million-ounce Carlin-Type gold deposit currently

being developed by Orla Mining."

QA/QC 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; 30g fire assay) and ICP-5AM48 (48 element

Suite; 0.5g 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.

The technical information contained in this news release has been prepared under the supervision of,

Project

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

14

from structurally controlled

skarn deposits outcropping between the Delker and Skarn Hill mines. 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+ kms of untested strike towards the Medicine Springs project. Big Blue is 100% owned by the

Company and is comprised of a total of fifty square kilometers of highly prospective exploration ground.

Atlas Project

Atlas is located in Eureka County, Nevada, approximately 30 kilometers southwest of the town of Carlin,

NV. The property exhibits classic Carlin-Type alteration and gold mineralization within outcropping

Pennsylvanian to Permian age carbonate to siliciclastic host rocks. The primary target at Atlas is a bulk

tonnage, oxide, Carlin-Type gold system, which is analogous to the nearby Dark Star gold deposit (part

of the greater Railroad Mining District), which is currently owned by Orla Mining and advancing towards

mine development. The 100% owned Project is comprised of a total of six square kilometers of highly

prospective exploration ground that has never been drill tested and will benefit from the Ridgeline teams'

systematic approach to discovery (view the Ridgeline Corporate Deck
