Ridgeline Minerals Commences Drill Program at the Big Blue Porphyry Cu-Au Project, Nevada

Ridgeline Minerals Commences Drill Program

at the Big Blue Porphyry Cu-Au Project,

Nevada

Vancouver, British Columbia--(Newsfile Corp. - March 11, 2025) - Ridgeline Minerals Corp. (TSXV:

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

Ridgeline

" or the "

Company

") is pleased to announce the

commencement of the Company's diamond core drill program at the Big Blue ("

Big Blue

" or "

Project

")

porphyry copper ("Cu") - gold ("Au") project in Elko County, Nevada (

Figure 1

). The maiden drill program

has been designed to test high-priority chargeability and resistivity anomalies located directly beneath

the historically producing Delker Mine trend (see January 20, 2025 press release

HERE

) with the goal of

intersecting the proposed porphyry source to the high-grade Cu-skarn observed at surface. The program

will complete an initial 2-hole fence of up to 1,800 meters ("m") starting with core hole BB25-001, with

results to be released as they are received (

Figure 2

).

Mike Harp, Ridgeline's Vice President, Exploration commented, "The first of two planned core holes

is in progress and will be drilled beneath the historic Delker mine and directly across the porphyry

dike swarm that is the interpreted source to the high-grade Cu-skarn at surface. Our recent IP survey

has identified multiple highly prospective porphyry centers at Big Blue with the past producing Delker

Mine trend being our shallowest and highest priority target. We will provide regular updates as the

program progresses."

Drill Program Objectives

The initial program at Big Blue has been designed to test key structural and geophysical targets along

the Delker Mine trend with the goal of intersecting high-grade Cu-skarn and/or porphyry Cu-Au style

mineralization at depth.

BB25-001 will drill across the projected quartz feldspar porphyry ("QFP") dike swarm and directly

down-dip of the high-grade past producing Delker Mine (

Figure 2

)

Hole will test both chargeability and resistivity anomalies identified in the Company's 2024 IP

survey and has the potential to intersect both skarn and porphyry Cu style alteration and

mineralization

Potential for a 2

nd

steeper angle hole beneath BB25-001 depending on visual results of the

first hole

BB25-002 will drill a near-vertical hole into the core of the 20-25 mV/V chargeability high that

underpins the Delker Mine trend (

Figure 1

)

This hole will target the conceptual porphyry source to the shallow high-grade Cu-skarn that

was mined near-surface

models. Core hole BB25-001 will drill down-dip of the historic, high-grade Delker Mine and test both the

chargeability and resistivity anomalies that underpin the Delker Mine trend. Note the prominent resistivity

anomaly, which is interpreted as upwelling Cu-rich fluids during porphyry emplacement

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 50 square kms of highly prospective exploration ground that will

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

).

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.
