Ridgeline Minerals Expands Copper-Gold
Porphyry Targets with Infill IP Survey at the
Big Blue Project, Nevada
Vancouver, British Columbia--(Newsfile Corp. - January 20, 2025) - Ridgeline Minerals Corp. (TSXV:
RDG) (OTCQB: RDGMF) (FSE: 0GC0) ("
Ridgeline
" or the "
Company
") is pleased to announce the
results of its Phase II, induced polarization ("IP") geophysical survey at the Big Blue ("Big Blue") porphyry
copper ("Cu") - gold ("Au") project in Elko County, Nevada. The pole-dipole infill survey was collected in
December 2024 by Moombarriga Geoscience and consisted of an additional eight line-kilometer ("line-
km") survey across three high-priority IP lines in the Delker Mine area to complement the original twenty-
eight line-km survey collected in August 2024.

The Phase II survey infilled lines between the Skarn Hill and Delker mines, which historically produced
94,434 pounds of copper at an average grade of 6.2% between 1916-1917
1
from near surface, high-
grade, Cu-bearing skarn. The mines overlie an approximately 2.0 km long by 1.0 km wide chargeability
high, which is interpreted as the potential blind porphyry source to the high-grade Cu Skarn previously
mined across the Delker trend (
Figure 1
). Merlin Geophysics oversaw data processing and subsequent
interpretation of the raw IP data with highlights of the survey below.
Michael Harp, Ridgeline's Vice President, Exploration, commented, "The Phase II infill results have
expanded the kilometer-scale chargeability high underpinning the Delker Mine trend, which we
interpret as the porphyry source to the high-grade copper skarn at surface. We also observe a
continuous resistivity anomaly located directly adjacent to the inferred porphyry target that exhibits a
strong vertical control and is interpreted as zones of upwelling fluids during porphyry emplacement.
These fluids are an indicator of a strong hydrothermal system at depth and a likely contributor to the
pervasive skarn alteration and copper mineralization that was historically mined across the Delker
trend."
Michael Harp continues: "We are fully permitted and bonded for our maiden drill program, which is
scheduled to begin in early March. The initial core holes will test for the continuation of high-grade
copper skarn and porphyry dikes beneath the historical mine workings followed by a direct test of the
chargeability high with the goal of identifying a porphyry copper-gold system at depth."
IP Survey Highlights
IP Line 71500N to 72900N highlights a kilometer-scale chargeability and coincident resistivity anomaly
located directly down-dip of the Skarn Hill and Delker Mines
(
Figure 1
)
Chargeability:
The chargeability high measures roughly 2km long by 1 km wide and is interpreted
as the potential porphyry source to Cu-Au mineralization along the greater Delker Mine trend
Chargeability values in the core of the anomaly consistently average 20-25 Millivolts per volt
("mV/V"), which is consistent with chargeability values observed in the productive horizons of
many known porphyry systems (
Figure 2
&
Figure 3
)
Resistivity:
The highest priority resistivity anomaly is a subvertical feature that extends across the
entire Delker trend and averages between 150-350 ohm.m (highs of up to 500 ohm.m)
This anomaly exhibits a bias to the western margin of the dike swarm, which is interpreted as
emanating from the Delker porphyry/chargeability anomaly at depth (
Figure 3
&
Figure 4
)
Resistivity values between 100-500 ohm.m is considered relatively low compared to the
background values of unaltered host rocks at Big Blue, suggesting the presence of a significant
alteration cell beneath the Delker trend
Decreased resistivity may be explained by pervasive alteration and subsequent sulfide
deposition within both carbonate and QFP dike host rocks during porphyry emplacement
Maiden Drill Program
Drill planning for an initial 2,000-meter core program is in progress with an anticipated start date of
March 3, 2025. The Company intends to drill test two primary targets in the maiden drill program
including:
1
.
Drill down-dip of outcropping high-grade Cu-bearing skarn mineralization in the Delker Mine area
to transect the QFP dike swarm (genetic link to deeper porphyry source) and coincident resistivity
anomaly
2
.
Drill the core of the Delker chargeability anomaly to test for the blind porphyry Cu-Au source to the
QFP dikes and high-grade skarn observed at surface

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 shipped 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 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+ kilometers of untested 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
