Vancouver, British Columbia--(Newsfile Corp. - August 8, 2025) - Ridgeline Minerals Corp. (TSXV:

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

Ridgeline

" or the "

Company

") is pleased to provide assay

results for the maiden two-hole drill program at the Company's Atlas project, Nevada (

Figure 1

). Atlas is

an early-stage Carlin-Type oxide gold prospect and is 100%-owned by the Company with no underlying

work commitments or royalties. Details on the drill program are highlighted below.

Mike Harp, Ridgeline's Vice President, Exploration commented, "We are pleased that our maiden

drill program confirmed that our Atlas project exhibits both the scale and grade potential that's

required to host a significant gold deposit. The first two drill holes at Atlas were completed in the

northernmost section of a greater than four-kilometer gold trend. With a limited budget this year, our

focus was testing the favourable Pennsylvanian to Permian age carbonate host rock section to

confirm whether those host rocks showed evidence of a Carlin-Type gold system."

Mr. Harp continues, "Both holes returned thick intercepts of anomalous oxide gold and Carlin-Type

alteration, with hole AT25-001 exhibiting a stronger gold vector to the south than AT25-002. Hole

AT25-001 intersected 298 meters of continuous Carlin-Type alteration and mineralization with

elevated pathfinder elements, anomalous gold, and up to 1.8 g/t gold in individual samples."

Mr. Harp concludes, "Mineralization at Atlas appears to be hosted within the same thick section of

Pennsylvanian to Permian age host rocks that host Orla Mining's nearby Dark Star deposit. Our team

interprets the first two holes as having intersected a low-grade gold and trace element halo that is

typically associated with the outer margins of Carlin-Type gold deposits. We will continue to focus on

land consolidation and additional field work throughout the remainder of the 2025 field season with the

goal of a Phase II drill program in 2026 to follow up on these results."

Drill Program Highlights

The maiden program completed two core holes totaling 551 meters ("m") in the northern section of the

Atlas land package. Drilling targeted favourable Pennsylvanian to Permian ("Penn-Perm") age debris-

flow conglomerates, limestones, and siltstone host rocks along a roughly 1-kilometer ("km") trend of

elevated gold-in-soils and rock chips grading up to 7.7 g/t Au (

Figure 2

).

AT25-001 drilled to the east and down-dip of gold bearing and partially eroded Penn-Perm host rocks

and intersected a highlight intercept of:

0.2 m grading 1.80 grams per tonne ("g/t") gold ("Au") and 2.10 g/t silver ("Ag") within 8.5

m grading 0.20 g/t Au and 0.52 g/t Ag

starting at a true vertical depth ("TVD") of 80 meters

(

Figure 3

&

Picture 1

)

Additional results include multiple 1.0 to 5.0-meter intercepts throughout the hole ranging

from 0.1 to 0.5 g/t Au and 0.1- to 5.0 g/t Ag starting at 30m TVD

Drilling also intersected high-grade silver intercepts within clay altered fault zones that returned

1.5m grading 75.1 g/t Ag and 0.5m grading 52.5 g/t Ag (

Figure 3

)

The hole returned 297.9m grading 0.01 g/t Au, 0.41 g/t Ag and bottomed in anomalous Au

mineralization

AT25-002 was collared approximately 700m north of AT25-001 and drilled to the west towards the same

gold bearing and partially eroded Penn-Perm host rocks and intersected a highlight intercept of:

5.9m grading 0.20 g/t Au and 2.43 g/t Ag starting at 124m TVD and;

2.6m grading 0.25 g/t Au and 2.59 g/t Ag within 9.8m grading 0.15 g/t Au and 2.20 g/t Ag starting

at 182 m TVD (

Figure 2

) and;

1.4m grading 31.6 g/t Ag within a clay altered fault zone

The top of AT25-001 intersected 106m of andesite (volcanic rocks) with the remainder of the hole

drilling a partial section of Penn-Perm rocks that returned 147.6 m grading 0.01 g/t Au and 0.41 g/t

Ag

Geologic Interpretation

Both holes intersected a thicker than anticipated section of Penn-Perm debris-flow conglomerate host

rocks (150-300m), which exhibited weak to strong Carlin-Type alteration and oxide mineralization

throughout with both holes bottoming in oxide mineralization.

Anomalous gold-silver and Carlin-type trace element pathfinders were observed throughout both

drillholes with the highest values (up to 1.8 g/t Au and 75.1 g/t Ag) associated with strongly altered

and mineralized Penn-Perm carbonate host rocks

Compared to AT25-001, hole AT25-002 exhibited similar zones of widespread silicification,

decalcification, and oxidation. However, AT25-002 returned weaker Au values overall

Results from these two holes indicate a potential vector to the south where the intersection of a

northeast and northwest trending fault corridor coincides with a kilometer-scale gold in soils and

rock chip anomaly

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 at AAL and analysed using a photon assay (Au-Ag,

500g) at Paragon. AAL and Paragon also undertake their 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.

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.
