Vancouver, British Columbia--(Newsfile Corp. - November 4, 2025) - Ridgeline Minerals Corp. (TSXV:
RDG) (OTCQB: RDGMF) (FSE: 0GC0) ("
Ridgeline
" or the "
Company
") is
pleased to announce a new
high-grade zinc ("Zn") - silver ("Ag") - gold ("Au") - lead ("Pb") - copper ("Cu") - antimony ("Sb") massive
sulfide carbonate replacement ("CRD") discovery in the second hole of the Company's maiden drill
program testing the Chinchilla Sulfide target at the Selena project ("Selena" or "The Project"), Nevada.
Drilling has intersected multiple massive sulfide horizons to-date with full assay results for core hole
SE25-052A as well as assays for the first two of four massive sulfide intervals in SE25-053, which are
highlighted below (
Picture 1
&
Figure 1
).
The Project is currently being operated by Ridgeline under Phase 1 of an earn-in agreement with a
wholly owned subsidiary of South32 Limited. ("South32"), where South32 may earn up to an 80%
interest in the Project by executing all earn-in agreement milestones (see August 22, 2024 news release
HERE
).

Chad Peters, Ridgeline's President, CEO & Director commented, "This is an exciting day for
Ridgeline with our maiden drill program at the Chinchilla Sulfide target delivering a high-grade CRD
discovery. Hole SE25-053 has intersected multiple massive sulfide horizons within the kilometer-
scale MT anomaly that defines the Chinchilla Sulfide target, suggesting the potential to delineate a
polymetallic CRD deposit of considerable scale. This discovery is just getting started and I'd like to
congratulate our technical team, led by Ridgeline's Vice President of Exploration Michael Harp, as
well as our partners at South32 who shared in our belief that the Selena Project had the potential to
host a blind CRD system at depth."
Mr. Peters continues, "With zinc, silver, copper and antimony all designated as critical metals by the
U.S. government, Selena is uniquely positioned in the State of Nevada as a future domestic supplier
of precious and critical metals. Drilling will continue through the end of the year, and we will provide
regular updates as assays are received for this rapidly evolving discovery."

SE25-053 Highlights
Drillhole SE25-053 returned the first massive sulfide intercepts in the project's history with a highlight
intercept of:
1.1m grading 27.0% Zn, 60.1 g/t Ag, 1.5 g/t Au, 0.7% Pb, 0.4% Cu and 0.03% Sb (766.4 g/t
silver equivalent ("AgEq") or 31.9% zinc equivalent ("ZnEq"))
starting at 942.4m downhole
(
Figure 2
&
Picture 1
)
And;
17.4 meters grading 6.0% Zn, 35.6 g/t Ag, 0.2 g/t Au, 0.5% Pb, 0.1% Cu, and 0.1% Sb
(219.9 g/t AgEq or 9.2% ZnEq)
starting at 958.0m downhole (
Figure 2
and
Figure 3
)
Including, 8.6 meters grading 10.4% Zn, 21.1 g/t Ag, 0.3% Pb, 0.1% Cu, 0.1 g/t Au,
0.1% Sb (273.6 g/t AgEq or 11.4% ZnEq)
And, 0.4m grading 4.2% Zn, 379.0 g/t Ag, 1.2 g/t Au, and 7.2% Pb (586.4 g/t AgEq or
24.4% ZnEq)
Mineralization occurs as classic CRD, replacement style semi-massive to massive sulfides with a
primary metal assemblage of Sphalerite-Pyrrhotite-Pyrite-Galena-Chalcopyrite (listed in order of
relative abundance) (Picture 1)
Massive sulfide horizons intercepted to-date range from 0.5m - 17.4m thick and are hosted within
the favourable host rocks of the Guilmette Limestone (Chinchilla Oxide Zone host)
Individual assay samples grading up to 27.0% Zn, 379.0 g/t Ag, 7.2% Pb, 1.5 g/t Au, 0.4%
Cu and 2.6% Sb highlight the high-grade nature of the discovery
SE25-053 Next Steps
Two additional massive sulfide horizons have been intersected (assays pending) beneath the
upper sulfide zone ranging from 6.0- 8.7m thick and exhibit similar zinc-rich metal assemblages
The lower portion of hole SE25-053 is currently drilling ahead at 1,304 depth to test the core
of the MT anomaly (25 ohm.m) where it is projected to intersect the Simonson Dolomite
formation (potential host rock).
The Company intends to terminate the hole between 1,350 - 1,400m depth

SE25-052A Highlights
Drillhole SW25-052A intercepted widespread calcite crackle breccias with intense BBQ rock (
Picture
2
), low-grade silver, and anomalous CRD pathfinder elements (Mn-Pb-Zn-As-Sb) over 250 continuous
meters in the core of the MT anomaly.
Reportable intercepts include 25.6m grading 4.0 g/t Ag, including 0.8m grading 30 g/t Ag and
0.2% Zn starting at 605.0m downhole (
Figure 3
)
And, 0.3m grading 43.8 g/t Ag starting at 984.0m downhole
The Company interprets this intersection as a proximal hit to the main CRD system with hole
SE25-052A drilling back to the west and along the outer margin of the MT anomaly
This interpretation is further supported by SE25-053 which successfully intersected massive
sulfide CRD mineralization by drilling to the east and directly across the MT anomaly
SE25-052A Next Steps
Future drilling from this drill pad will focus on drilling back to the east to intersect the MT anomaly
from a more favourable orientation

pathfinders (Mn-Pb-Zn-As-Sb) in calcite veining, which are proximal indicators of CRD mineralization

Earn-In Terms
- South32 retains the right to earn an initial 60% interest in the Selena project (see
August 22, 2024, press release
HERE
) by funding a minimum of US$10 million in qualifying work
expenditures on the Project over an initial five-year term, following which South32 will have a further
option to increase its interest in the Project to a total of 80% by funding an additional US$10 million in
qualifying work expenditures (for an aggregate spend of US$20 million) over an additional three-year
term. If South32 wishes to exercise the Phase 2 option, it must arrange for and provide draft definitive
documentation in respect of a debt facility from which (if executed) Ridgeline may draw on to sufficiently
fund Ridgeline's share of costs (20% pro-rata) associated with development of a mine at Selena through
to commercial production.
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,

Selena Project
Selena is located in White Pine County, Nevada, approximately 64 kilometers ("km") north of the town of
Ely, NV. The Project is currently being operated by Ridgeline under Phase 1 of an earn-in agreement
with a wholly owned subsidiary of South32 Limited ("South32") and shares a property boundary with the
Butte Valley project, a $33M earn-in agreement between Freeport-McMoRan and the underlying owner,
Falcon Butte Minerals. The Project is comprised of 39 square kilometers of highly prospective
exploration ground including Ridgeline's shallow-oxide Ag-Au ± Pb-Zn Chinchilla Oxide and deeper
Chinchilla Sulfide discoveries. Subsequent drilling has continued to highlight the potential for high-grade
CRD type mineralization (Ag-Zn-Pb-Au ± Cu-Sb-W) between Chinchilla Oxide and Freeport-McMoRan's
Butte Valley Cu-Au-Ag-Zn porphyry located directly west of the property.
