Ridgeline Minerals Provides Drill Program

Updates for Its Three Partner Projects in

Nevada

Vancouver, British Columbia--(Newsfile Corp. - September 9, 2025) - Ridgeline Minerals Corp. (TSXV:

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

Ridgeline

" or the "

Company

") is pleased to provide

exploration updates for ongoing drill programs at the Swift, Black Ridge and Selena exploration projects

located in north-central Nevada (

Figure 1

). The Swift and Black Ridge gold projects are operated by

Nevada Gold Mines ("NGM") and are both in Phase 1 of separate exploration earn-in agreements

totaling US $40,000,000 in potential earn-in expenditures. Ridgeline remains the operator at the Selena

CRD project, which is in Phase 1 of an earn-in agreement with a wholly owned subsidiary of South32

Limited ("South32") totaling US $20,000,000 in potential earn-in expenditures.

The combined partner-funded 2025 exploration budget of US $9,500,000 represents the largest

exploration budget in Company history with assays pending at all three projects through Q4 of 2025 and

into Q1 of 2026.

Chad Peters, Ridgeline's President, CEO & Director commented, "Drilling is progressing smoothly

across our three partner projects with both Swift and Selena close to finishing up the first deep core

tails of their respective programs. NGM has also recently completed a single framework drill hole at

Black Ridge, which is on-trend of NGM's Leeville Mine and Fallon Deposit

1

to the south. We expect

drilling to continue at Swift and Selena through the end of 2025 with steady news flow and assay

results throughout the end of the year."

Selena Project (US $20,000,000 South32 Earn-in)

The drill program at Selena has been in progress since June with the first core tail commencing in late

July. The US $3,450,000 budget will drill up to three deep core holes (4,500 meters total) targeting the

highly conductive Magnetotellurics ("MT") anomaly that was identified at the Chinchilla Sulfide CRD

target in early 2025 (

Figure 2

). For a detailed summary of the drill program see the June 23, 2025 press

release

HERE

.

South32 has incurred a total of

US $573,758

in qualifying work expenditures at the Project through June

30, 2025, and must spend a minimum of

US $10,000,000

in qualifying work expenditures by August 21,

2029, to earn an initial 60% interest in the Project (see August 22, 2024 press release

HERE

).

Swift Project (US $30,000,000 NGM Earn-in)

The first of up to five holes is in progress and testing along strike of previous high-grade gold intercepts

(up to 1.1m grading 10.4 g/t Au in SW24-006) at the projected intersection of cross cutting fault zones

(i.e., fluid conduits) where they intersect a modeled fold hinge (i.e., fluid trap), on the hanging wall side of

the Mill Creek thrust (

Figure 3

). For a detailed summary of the drill program see the July 30, 2025 press

release

HERE

.

NGM has incurred a total of

US $10,869,000

in qualifying work expenditures at the Project through June

30, 2025, and must spend a minimum of

US $20,000,000

in qualifying work expenditures by December

31, 2026, to earn an initial 60% interest in the Project (see September 22, 2021 press release

HERE

).

Black Ridge Project (US $10,000,000 NGM Earn-in)

One deep core hole was completed by NGM in August with the primary goal of testing the same lower-

plate host rock section that hosts multiple past and currently producing gold deposits on the north Carlin

Trend

1

(

Figure 4

). Samples are being prepared for assay with results anticipated in Q4, 2025.

NGM has incurred a total of

US $586,904

in qualifying work expenditures at the Project through June 30,

2025, and NGM must spend a minimum of

US $4,500,000

in qualifying work expenditures by July 14,

2028, to earn an initial 60% interest in the Project (see July 17, 2023 press release

HERE

).

QAQC Procedures

Selena 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.

Swift and Black Ridge samples are submitted to ALS Minerals, Elko Nevada, which is a certified and

accredited laboratory, independent of Nevada Gold Mines. Samples are prepared using industry-

standard prep methods and analysed using Au-AA23 (Au; 30 g fire assay) and ME-MS61 (48 element

Suite; 0.25 g 4-acid digestion/ICP- MS) methods. ALS also undertakes its own internal coarse and pulp

duplicate analysis to ensure proper sample preparation and equipment calibration. Nevada Gold Mines

QAQC program includes regular insertion of CRM standards, duplicates, and blanks into the sample

stream with a stringent review of all results completed internally by Nevada Gold Mines technical

personnel.
