Vancouver, British Columbia--(Newsfile Corp. - February 25, 2025) - Ridgeline Minerals Corp. (TSXV:
RDG) (OTCQB: RDGMF) (FSE: 0GC0) ("
Ridgeline
" or the "
Company
") is pleased to announce the
results of the Magnetotellurics ("MT") Geophysical survey completed in late 2024 at the Selena
Carbonate Replacement ("CRD") project ("Selena" or "Project") (
Figure 1
). The MT survey has identified
a strong, kilometer-scale conductive anomaly that suggests the potential for the Chinchilla Sulfide target
to host a robust silver ("Ag") - gold ("Au") - lead ("Pb") - zinc ("Zn") CRD system at depth. Given these
results, budgeting and planning in support of an accelerated 2025 Phase I drill campaign is currently in
progress.
The Project is currently being operated by Ridgeline under Phase 1 of the earn-in agreement with a
wholly owned subsidiary of South32 Limited ("South32"). Highlights of the MT survey are detailed below.
Mike Harp, Ridgeline's Vice President, Exploration commented, "The CRD target coming together at
Chinchilla Sulfide has exceeded our teams' expectations in every way. The scale and intensity of the
MT anomaly, combined with two high-grade intercepts drilled by our team in 2022 that tested the
edges of the previously unknown MT anomaly now suggests we are vectoring towards a sulfide CRD
horizon at depth."
Mr. Harp continues, "Drill planning is in progress for our 2025 program and the inclusion of the MT
data into our geological model has allowed us to more efficiently target the highest priority anomalies
at depth. We have a high degree of confidence in the MT interpretation given that our partners at
South32 have utilized MT geophysics to identify mineralized CRD trends at the Taylor deposit, part of
South32's Hermosa project in Arizona."
MT Survey Highlights
Chinchilla Sulfide
- Geologically constrained 3D inversion modeling of the MT survey has
identified a large conductive anomaly with dimensions of approximately 1.5 kilometers ("km") wide
by 600 meters ("m") in estimated thickness, and extends for over 2.0 km along strike (
Figure 2
&
Figure 3
)
The "core" of the MT anomaly ranges from 25.0 - 100.0-ohm meters ("Ω.m"), which is highly
conductive and interpreted as a broad zone of CRD alteration and sulfide mineralization
Reverse circulation ("RC") hole SE22-037 (2022 DDH) intersected
3.0m grading 40.2
grams per tonne ("g/t") Ag, 7.0% Pb-Zn and 3.0 g/t Au (or 605.3 g/t AgEq)
within 15.3m
grading 12.30 g/t Ag, 1.7% Pb-Zn and 0.8 g/t Au (or 156.3 g/t AgEq) starting at 735m
downhole
RC hole SE22-038 intersected
1.5m grading 97.4 g/t Ag, 5.0% Pb-Zn and 0.4 g/t Au (or
342.9 g/t AgEq) starting at 765m downhole
Holes 37 and 38 were drilled on either side of the MT anomaly and were targeting
magnetic highs, which are now interpreted as system bounding fault structures
Due to the depth limitations of the RC rig, both holes were stopped directly above
the 100-250 Ω.m MT contours, which is interpreted as the outer extents of the
sulfide CRD horizon (
Figure 2
&
Figure 3
)
Chinchilla Oxide
- The MT survey highlights a weakly conductive anomaly (500 -1,000 Ω.m) that
directly correlates with known oxide CRD mineralization (
Figure 2
).
Supports the Company's interpretation that shallow oxide mineralization (less conductive) is
transitioning to sulfide mineralization (more conductive) at the Chinchilla Sulfide target
Geologic Controls
- The geometry of the Chinchilla Sulfide MT anomaly is directly controlled by:
East verging thrust faults and northeast striking normal faults,
and;
Intersection of the aforementioned structures with reactive carbonate host rocks of the
Guilmette, Simonson and Sevy Formations, which exceed 500m in total thickness (
Figure 3
)
Figure 1
: Plan view map of the Selena project showing MT contours across the Chinchilla Sulfide target.
The contours highlight a 2+ kilometer long anomaly ranging from 25 Ω.m (highly conductive) to 250 Ω.m
(moderately conductive). The anomaly is interpreted as a broad zone of potential CRD alteration and
mineralization, which is supported by high-grade CRD intercepts from 2022 drilling that flank the
anomaly

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. During the Phase 2 earn-in period, South32 has the option to take over operatorship of the Project.
Before exercise of the Phase 2 option, South32 will 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.

Selena Project
Selena is located in White Pine County, Nevada, approximately 64 kilometers ("km") north of the town of
Ely, NV. The Project shares a property boundary with the Butte Valley project, a US $33M earn-in
agreement between Freeport-McMoRan and the underlying owner, Falcon Butte Minerals. The 100%
owned project is comprised of 39 square km's 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-
Au-Pb-Zn ±Cu-W) between Chinchilla Oxide and Freeport-McMoRan's Butte Valley Cu-Au-Ag-Zn
porphyry located directly west of the property.
