Ridgeline Minerals Reports Additional Assays for the Chinchilla Sulfide CRD Discovery at the Selena Project, Nevada
Ridgeline Minerals Reports Additional Assays
for the Chinchilla Sulfide CRD Discovery at the
Selena Project, Nevada
Vancouver, British Columbia--(Newsfile Corp. - December 18, 2025) - Ridgeline Minerals Corp. (TSXV:
RDG) (OTCQB: RDGMF) (FSE: 0GC0) ("
Ridgeline
" or the "
Company
") is pleased to announce
additional assay results for discovery drillhole SE25-053 at the Selena project ("Selena" or "Project") in
Nevada. The lower sulfide horizon was intersected 94 meters beneath the previously announced upper
zone discovery and returned a highlight intercept of
8.7 meters ("m") grading 175.5 g/t silver
equivalent ("AgEq") or 7.3% zinc equivalent ("ZnEq")
starting at 1,069m downhole (
Figure 1
&
Picture 1
).
Chad Peters, Ridgeline's President, CEO & Director commented, "Discovery hole SE25-053 has
exceeded our expectations for a maiden drill program, intersecting three high-grade CRD horizons
with a cumulative mineralized thickness of 27.2 meters. We are especially encouraged to have hit
multiple stacked sulfide lenses in a single hole, which show evidence of base metal zoning and further
support our interpretation that Selena hosts a multi-phase CRD system with significant growth
potential."
Mr. Peters continues "We are still in the early days of a new discovery but with individual samples
grading up to 27% zinc and 379 g/t silver, we believe Selena has the potential to deliver even higher
grades as we continue to vector into the core of the CRD system. Follow up drillhole SE25-054 is in
progress with assay results to be released as they are received in 2026."
SE25-053 Highlights
1.1m grading 27.0% Zn, 60.1 g/t Ag, 0.7% Pb, 1.5 g/t Au, 0.4% Cu, 0.03% Sb (766.4 g/t
AgEq or 31.9% ZnEq)
starting at 943m downhole, true thickness unknown (

And:
17.4 meters grading 6.0% Zn, 35.6 g/t Ag, 0.5% Pb, 0.2 g/t Au, 0.1% Cu, 0.1% Sb
(219.9 g/t AgEq or 9.2% ZnEq)

Drillhole SE25-053 is the second of the Company's three-hole maiden drill program testing the
Chinchilla Sulfide target and represents a new CRD discovery. Hole SE25-054 is in progress and
represents a roughly 700m step-out to the northeast of hole SE25-053 to test the extension of the same
kilometer-scale MT conductive anomaly (

The Project is currently 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 satisfying all commitments under the earn-in agreement (see August 22, 2024 news release
HERE
).
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 shipped 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
