- Over 800 outcrop chip samples highlighting a widespread
silver-lead-zinc-copper system. Grades up to 21% copper at the Big
Cut Skarn and 2,810 g/t silver in the untested Grade Creek
Zone1
- Results confirm a multi-kilometer-scale system, delimited by
a number of mineralized zones which may be contiguous under surface
cover
- Majority of samples collected from scattered bedrock
exposures of Hercules Rhyolite are mineralized and strongly
altered
- The best historical drilling intercepts lie below low grade
surface samples at Hercules Adit and Frogpond, suggesting leaching
may be downgrading geochemical values at surface
- The strongest and most consistent silver-lead-zinc grades on
surface occur within the untested Grade Creek Zone, which also
hosts the strongest historical chargeability and soil sampling
values
- Lack of bedrock exposure restricted sampling of several
parts of the Hercules Rhyolite on surface, however recent IP
geophysics indicates the potential for continuous sulfide
mineralization at depth (See Dec 15,
2022 NR)
- Rhyolite host for silver-lead-zinc mineralization remains
open under post-mineral basalt cover to the south of the map area,
with 7 additional samples pending from a historical adit uncovered
by recent prospecting

TORONTO, Jan. 24,
2023 /CNW/ - Hercules Silver
Corp. ("Hercules Silver" or the "Company")
(TSXV: BIG) (OTCQB: BADEF) (FWB: 6W0) is pleased to announce
widespread silver, lead, zinc and copper values from its 2022 rock
chip sampling program on the Hercules Property located in western
Idaho ("Hercules" or the
"Property"). The Company collected over 800 rock chip
samples to identify the source of previously announced soil
anomalies on the Property. The new results outlined the presence of
a large mineralized system, consisting of multiple outcropping
zones of silver-lead-zinc, spanning approximately 3.5 kilometers of
exposed Hercules Rhyolite, as well as two distinct copper targets,
the Metheny and Big Cut, hosted within Triassic aged Seven Devils
Group rocks.

A plan presenting the rock chip grades in silver equivalent
(AgEq2, g/t), is shown in Figure 1. A silver equivalent
calculation was used for compilation purposes only, to compare the
combined metal value from samples taken across the Property.
Investors are cautioned that the silver contribution varies
significantly from sample to sample, particularly at the Metheny
and Big Cut Zones, which are copper dominant targets. It should
also be noted that estimated recoveries of individual metals were
not applied in the AgEq calculation. Separate maps of silver, lead,
zinc and copper are presented in Figures 2-5.
Sampling was restricted to limited exposures of outcropping
bedrock and the majority of samples that were collected from the
Hercules Rhyolite, where exposed, are well mineralized and show
strong alteration. A series of zones mineralized with
silver-lead-zinc are exposed along an approximate 3.5-kilometer
strike length of rhyolite, and are open under Tertiary basalt cover
to the south. An IP geophysical survey conducted in late summer of
2022 suggests that these zones may connect at depth.

equivalent (AgEq) grades are calculated using metal prices of:
silver US$24/oz., copper US$4.15/lb, lead US$1.00/lb and zinc
US$1.50/lb. Silver equivalent grade is calculated as AgEq (g/t) =
Ag (g/t) + (Cu (%) * 118.558) + (Pb (%) * 28.568) + (Zn (%) *
42.852). Metal recoveries have not been applied in the silver
equivalent calculation.

Management Commentary
Chris Paul, CEO and Director of
the Company, noted: "We're excited by the consistency of
mineralization and alteration we are seeing over such a large area
at Hercules. These results demonstrate widespread geochemical
anomalies, and further strengthen our targeting effort at Hercules.
The strong IP chargeability values released last month indicate
that these zones may connect to a larger body of sulfide
mineralization at depth. We acquired the project in 2021 with a
view that shallow historical drilling had only just scratched the
surface at Hercules. The historical drilling had focused on
Frogpond and Hercules Adit, which together represent less than 5%
of the mineralized footprint, and it appears now that a large
amount of blue sky exists outside of that."
Potential for Increasing Grades
Below Surface
The Hercules Adit and Frogpond Zones were the focus of
historical drilling, where 189 of the 308 historical holes were
drilled. The area was also the focus of a small-scale feasibility
study completed in 1984. Despite the best historical drilling
intercepts being returned from this area, they show the lowest
grades on surface, out of all the zones sampled (Figure 1). This
supports conclusions from previous operators, that significant
leaching of metal values has occurred at surface, as much stronger
grades were reported in historical holes drilled within these
zones. The eastern side of the Frogpond has also been covered by a
landslide, consisting of barren andesitic lapilli tuff transported
from the east, as indicated by the hash marks on Figure 1. This
indicates that excellent subsurface grades may be discovered in
areas with relatively subdued surface geochemistry.
Grade Creek – Best Untested Target
on the Property
The Grade Creek Zone remains the best untested target on the
Property for silver-lead-zinc mineralization. The most consistent
and highest surface grades, both in soil sampling as well as the
new rock chip samples, occur along the north facing slope of Grade
Creek, which has never been tested by drilling. Historical IP
surveys, which covered the area from Hercules Adit to Grade Creek,
also reveal a large and strong (>25ms) chargeability anomaly
underlying the strong surface geochemistry. The steep north facing
slope of Grade Creek does not have existing road access but can be
tested with long drill holes, collared from a nearby road on
Hercules Ridge. 2022 mapping indicates that the rhyolite dips
subparallel to the slope, giving it a favourable open pit type
target geometry. It therefore ranks as a high priority target and
the Company is preparing a drill plan to permit and test the
zone.
Metheny and Big Cut Copper Skarn
Zones
Two high-grade copper-silver targets, the Big Cut and the
Metheny, occur within the Triassic Seven Devils Group on the east
side of the Property. Both targets represent skarn style
mineralization, which occurs where limestone comes in contact with,
or close proximity to, a nearby porphyry intrusion. The Big Cut is
characterized as a garnet-epidote skarn, whereas the Metheny is a
specularite (iron) skarn. The differing alteration is likely a
function of zonation around a potential porphyry intrusion or
multiple intrusive centers at depth.
Historical trenching at the Big Cut prospect, discussed in
unpublished reports obtained by Hercules Silver3,4,
yielded grades of up to 1.78% copper across 90 feet (~27 meters)
and 1.3% copper across 57 feet (~17 meters). Silver was only
selectively assayed at the time. Other notable historical trench
intercepts at the Big Cut prospect include:
The assay results reported above are historical in nature and
have not been verified by a Qualified Person; therefore, they
should not be relied upon.
Photo's 1 and 2 below show select high-grade samples taken from
the Big Cut, displaying partially oxidized semi-massive
chalcopyrite (copper) mineralization.
The Metheny copper skarn is associated with lenses of brecciated
limestone within a larger quartz feldspar porphyry unit. High-grade
copper with moderate to strong silver grades of up to 1,085 g/t
occur with massive to semi-massive specular hematite, a different
type of skarn alteration than is seen at the Big Cut. The
surrounding quartz-feldspar porphyry is also altered and carries
copper mineralization. Photos 3 and 4 show examples of strong
iron-copper-silver skarnification at the Metheny.

Sampling Methodology
Outcrop and subcrop samples were collected based on the presence
of bedrock exposure throughout the Property. A polygon area of
interest was laid out on a GIS map, representing the outline of
anomalous soil samples on the Property. LiDAR data was also
hillshaded and used to map outcrop locations for sampling. Sampling
lines were established within the area of interest which acted as a
guideline for sample traverses, along with the mapped outcrop
locations. Any outcrops encountered within 50 meters of either side
of the sampling lines were sampled. A series of contiguous chip
samples were also collected from mineralized outcrops within the
Belmont Zone. Following collection, the samples were shipped to MSA
Labs in Langley, British Columbia
for analysis.
Sample Analysis and QAQC
All rock samples were prepped and analyzed at MSA Labs in
Langley, British Columbia, an ISO
17025 and ISO 9001 certified laboratory. Samples were dried and
crushed to 2mm, from which a 250g sub-sample split was then
pulverized to 85% passing a 75 micron sieve. Following preparation,
671 of 807 rock assays were determined by the IMS-230 method. A
0.25g aliquot of the prepared pulp was digested in a 4-acid
solution consisting of hydrochloric, nitric, perchloric and
hydrofluoric acids. 4-acid is a near total digest and only the most
highly resistant minerals are not dissolved. The resulting solution
was analyzed via ICP-MS and ICP-ES for 48 elements and was
corrected for inter-element spectral interferences. Mercury is not
reported due to volatilization in reaction with hydrofluoric acid
and gold is not reported due to the small, 0.25g aliquot size being
insufficient to overcome the nugget effect. Samples taken early in
the campaign (136) were analyzed by other ICP procedures, IMS-116,
IMS-117 or IMS-131, entailing a less complete aqua regia digestion.
Select samples are currently being analyzed by a 50g fire assay for
gold.
MSA Labs employs internal quality control standards, duplicates
and blank samples at set frequencies.
For submitted sample batches, excluding 52 of 807 total outcrop
samples, blind certified reference materials (CRMs) purchased from
CDN Resource Laboratories of Langley,
B.C., and duplicate samples were inserted by the Company at
a frequency of one in every 50 samples, totaling 23 analyses. CRM
results for copper, silver, lead and zinc were within acceptable
limits with only one result >2SD from the certified value and
none exceeding 3SD.
Fifteen barren rock blanks were inserted blind in five of the
sample batches. These yielded two 10x lower detection limit
failures for silver, four 10x failures for copper, and no failures
for lead and zinc. The Company is performing a follow-up on
the failures, but given the low thresholds of the exceedances, the
impact is not material to the identification of the strong
geochemical anomalies on the Property.
Fourteen duplicate samples were collected from the outcrops to
check sample precision for copper, silver, lead and zinc.
Considering the limited size of the data set and the presence of
outlier grades in some of the samples, the mean comparisons appear
reasonable, within ±15% for silver, copper and zinc. Removing
one outlier from the lead duplicate pairs, lead original and
duplicate means are within 5%. Scatterplots show reasonable
clustering along a linear trend line with no evidence of sample
mix-ups; correlation coefficients for originals and duplicates for
each metal are 0.95 or higher.
