Exploration Results from the Blackhawk
Mine and Surrounding Target Area at its
Ranger-Page Project in the Silver Valley,
Northern Idaho, USA
VANCOUVER, BC, Feb. 9, 2023 /CNW/ - Silver Valley Metals Corp.
(TSXV: SILV) (OTCQB: SVMFF) ("Silver Valley" or the "Company"), a
brownfields exploration Company with two potential high impact
projects that comprise silver-zinc-lead located in north Idaho, USA and
lithium - potassium (sulphate of potash) located in Zacatecas and San
Luis Potosi, Mexico respectively, is pleased to provide strong
exploration results from its Blackhawk Mine target at the Ranger-Page
Project, Silver Valley, Idaho.

Highlights:
• Significant near surface coincident Induced Polarization and
Resistivity anomaly matching historical trend of the Blackhawk
Mine.
• Strike and dip length of the coincident anomalies is
approximately 480 and 200 meters respectively located up
plunge from the first level of the Blackhawk mine.
• Mine remains open at depth below the 1200' level (465 metres
below elevation); no drilling has tested the down plunge
extension of the Blackhawk mine.
• Strike length of the mineralized silver-zinc-lead Curlew vein at
the bottom of the Blackhawk mine is approximately 370 metres
• Zinc, lead, and copper – strong anomalous geochemistry results
collected on surface and coincident with geophysics.
• Historic mining at Blackhawk: 214,126 tonnes grading 100 g/t
silver, 2.2% zinc and 8.1% lead – limited past recovery of zinc.
• One of seven high priority large target areas defined from 2022
exploration campaign constrained within a 3km x 2km area.

"The Blackhawk target has always been considered one of the highest
priority targets prior to the first exploration program," comments CEO,
Brandon Rook. With the exploration results now in hand, the
Blackhawk target appears larger than first contemplated. The ground
Induced Polarization and Resistivity geophysical surveys and
coincident geochemical results verify the target and with a planned
inaugural drill program scheduled in 2023 there is a significant target
to drill near the surface. A successful drilling program at Blackhawk
would be a great step forward, as access to the upper mineralization
occurrence would be cost-effective and would enhance the economics
of the lower Blackhawk target which is the continuation at depth of the
historic Blackhawk mine."
The deepest stope (where the ore is mined) in the Blackhawk mine is
situated 465m below surface, making it reachable from a surface
drilling platform. The Company believes the Curlew vein (Blackhawk
mine) is consistent with other significant deposits in the Silver Valley,
and has the potential to increase in width, grade, and strike length with
depth, if it intersects favorable host rocks, such as the Revett
formation which the Company believes is likely based on the recent
geological modeling of underground maps.

The Blackhawk mine ceased operations in 1944 after 21 years of
operation when the owner of the Page Mine, ASARCO, discontinued
operations despite the presence of mineralization in the deepest
stopes. The Blackhawk mine was leased by ASARCO from the
Blackhawk mine owners at that time to optimize ASARCO's Page
mine mill. Silver Valley Metals entered into an option agreement to
acquire 100% of the historic Page Mine – see press release

The Blackhawk target is located 1,000 metres east from the
Company's high-grade and top ten past-producer in the District, Page
Mine, and located 650 metres due west from the high-grade silver

The Blackhawk Mine and target area is one of seven high priority
target areas that the Company has defined from its successful 2022
exploration campaign. Importantly, all high priority areas are
constrained to a relatively small area approximately 3 kilometres X 2
kilometres and each target shows significant strike and depth
potential.

Geophysics Interpretation:
The ground Induced Polarization and Resistivity surveys indicate a
significant anomaly exists above the existing Blackhawk stopes, with
an interpreted plunge line matching the historical trend of the
Blackhawk Mine indicating the system is open up-plunge and along
the same dip.
The background Induced Polarization readings observed at the
Blackhawk host rocks was measured at 0-4 msec, as compared to the
background observed at the Prichard formation (+20 msec) located
north of the Blackhawk target. The Blackhawk Induced Polarization
anomaly ranges between 6 and 20 msec, which is an anomalous
result from the widespread dataset accumulated during the program.
Resistivity values are locally elevated (1,000 to +2,000 ohm) up
plunge of the Blackhawk stopes, and coincident with the polarization
results, indicating the likely presence of silicification, an alteration
closely associated with mineral occurrences in the Coeur d'Alene
mining district. The strike and dip length of the anomaly is
approximately 480 and 200 meters respectively. This ground Induced
Polarization survey is the first-time modern exploration techniques
have been deployed at the Blackhawk Mine to identify additional
mineralization, and this result represents a significant step forward in
our evaluation of the target.
Geochemical Program:
A surface geochemical program was initiated to further validate the
ground geophysics targets. Samples were collected from the B and C
soil horizons on a 30-metre spacing. At each location, a pit was dug
until refusal (could not dig deeper). The B and C soil horizons were
sampled separately to assess and compare geochemical results from
Ranger-Page weathered bedrock and soils to results published in
other Silver Valley geochemical studies. Samples were described,
photographed, staked and location data collected via GPS. Results
were loaded into Leapfrog Geo and displayed via a proportional grade
plot to highlight high values.

Results over the Blackhawk target are summarized below. The results
are consistent with the Company's expectation of a zinc-lead system
with lesser silver, in line with historic production records. Background
levels of lead, zinc and copper in the project area are typically 10 ppm,
40 ppm, 6 ppm respectively based on all 2022 geochemical data.
Average lead, zinc and copper values measured over Blackhawk are
59, 87 and 10 ppm respectively. Anomalous values for lead, zinc and
copper are 379, 183 and 22 ppm respectively. Trace element vector
analysis is ongoing, and we expect it will further validate the target.

Lab Analysis – QA-QC:
Atomic absorption analysis for Silver:
American Analytical Services, Inc ("AAS") is an ISO/IEC 17025
accredited laboratory, located in Osburn Idaho. All analysis includes
quality control measures to ensure an acceptance standard
established within AAS methods. All samples sent to AAS were
checked for accuracy between the chain of custody and the samples
with the client present. Samples are dried before starting the prep
process. The prep process includes crushing the sample in its entirety
to 80% passing a 10 mesh, split in a riffle box to make a 250g sub-
sample and pulverized to 85% passing a 140 mesh. Analysis for AA-
Ag is done by 2 or 4 acid digestion. Detection limit for AA-Ag is 0.100
Oz/ton - 15.0 Oz/ton. Any results over the detection limit are sent to
fire assay to do Ag gravimetric finish.
ICP-OES analysis for 35 element analysis:
All samples are subjected to a 4 acid digestion. Digestion QC consists
of a reagent blank, control standard and for every 20 samples there is
a duplicate of a sample pulp to check RPD. To begin ICP-OES
analysis, the instrument is standardized with the five working standard
solutions (multi-point linear fitting). Samples are then measured with
the reagent blank, control standard and a CCV (continuous calibration
verification). Once samples are analyzed, all QC is checked, and
results are sent to LIMS system to be made into the client's report.
