/CNW/ - Vizsla Copper Corp. (TSXV: VCU) (OTCQB: VCUFF)
(
FRANKFURT
: 97E0) ("
Vizsla Copper
" or the "
Company
") is pleased to report final drill results
from its summer core drilling program at the Woodjam and Redgold copper-gold projects in central
BC (Figure 1).
A polymictic breccia containing intrusive clasts with porphyry-related quartz-chalcopyrite±bornite
stockwork was intersected in two drill holes northwest of the Three Firs target. The clasts may
suggest proximity to a potentially mineralized and concealed copper-gold porphyry system. Future
drilling at Three Firs will target the source of the mineralized clasts.
HIGHLIGHTS
Drill holes TF24-123 and TF24-126 intersected a new zone of polymictic breccia
approximately 500 meters northwest of the Three Firs copper-gold target:
Breccia contains common intrusive clasts with quartz-chalcopyrite±bornite stockwork
Assays from the breccia returned up to 0.35% copper and 0.50 g/t gold, with mineralization
hosted mainly in the clasts
Results from a recent induced polarization (IP) survey across the Three Firs area
demonstrate an increase in chargeability in the down-plunge direction from the breccia
intersections
Future drilling will target the source of the mineralized clasts
Drill hole DH24-125 targeted the southern extension of the Deerhorn deposit:
50 meter step-out hole along strike to the south of the Deerhorn deposit intersected strong
alteration with individual assays up to 3.5% copper
2024 exploration program successfully:
Expanded the Deerhorn copper-gold deposit where mineralization remains open
Expanded and verified higher-grade copper-gold zones within the Southeast deposit
Generated high-priority exploration targets at the Great Plains and Three Firs areas
"
I'm very pleased with the results of our summer exploration programs,
" commented
Craig Parry
,
Executive Chairman. "
Woodjam continues to deliver exceptional exploration results, and the
mineralized breccia intersections at the Three Firs zone provide further evidence that additional
porphyry-related deposits are waiting to be found.
"
"Thanks to the excellent work of our field crews, the summer drilling program at Woodjam has
been very successful,"
commented
Steve Blower
, Vice President of Exploration
. "We've expanded
zones of high-value mineralization at both the Deerhorn and Southeast deposits, and with the
mineralized breccia intersections, we're possibly vectoring toward a new porphyry center at Three
Firs.
"
2024 Exploration Program
The 2024 exploration program at the Woodjam and Redgold projects (Figure 1) consisted of over
4,000 metres of diamond drilling in ten holes (seven at Woodjam and three at Redgold) and the
completion of over 40 line kilometres of induced polarization (IP) geophysical surveying across three
main target areas (Three Firs, Great Plains and Redgold).
The program successfully accomplished its two main objectives: 1) expand on high-grade porphyry-
related gold-copper mineralization at the Deerhorn and Southeast deposits (see
September 3
rd
,
2024 and
September 9
th
, 2024 news releases), and 2) define new exploration targets to be
evaluated in future drill programs (Three Firs, this release and Great Plains, see
October 30
th
, 2024
news release).
Three Firs
Drilling at Three Firs was designed to investigate the extent of near-surface, porphyry-related
copper and gold mineralization to the northwest. Drill holes TF24-123 and TF24-126, collared 500
meters from the core of the Three Firs target (Figure 2), intersected a new occurrence of polymictic
breccia containing intrusive clasts with porphyry-related quartz-chalcopyrite±bornite stockwork
(Figures 4 and 5).
Mineralized clast-bearing breccia was intersected over 41.6 meters (
363.4 m
to
405 m
at EOH) in
TF24-123 and in TF24-126 over two intervals including 27.6 meters (
499.7 m
to
527.3 m
, upper
breccia) and 39.9 meters (
598.15 m
to
638.0 m
, lower breccia). Based on clast composition and
texture, the breccia in TF24-123 is interpreted to be related to the upper breccia in TF24-126. The
breccia matrix in TF24-123 has been strongly clay+carbonate altered (Figure 4) whereas the matrix
in the upper breccia in TF24-126 is variably quartz-sericite-chlorite altered (Figure 5d). In both
intervals, clast compositions vary from intrusive (monzonite to granodiorite) with porphyry-related
stockwork, fractured and truncated quartz veins, to plagioclase porphyritic andesites, hornblende-
phyric diorites, and fine-grained volcanics/sediments (Figures
4b
, c, d, e and
5b
, c, d). Potassically
altered intrusive clasts are more abundant in TF24-126 and clasts with porphyry-related stockwork
mineralization are locally brecciated (Figures
4b
, d). The frequency of mineralized clasts within the
TF24-123 and upper TF24-26 breccias increases with depth from hole TF24-123 to TF24-126
corresponding to an increase in copper and gold grades. The breccia in TF24-126 returned 27.6
meters of 0.18% copper and 0.13 g/t gold relative to TF24-123 which yielded 41.6 meters of 0.06%
copper and 0.03 g/t gold (Table 1 and Figure 3). The lower breccia in TF24-126 (Figure 6) contains
strongly sericite altered andesite clasts set in a quartz-pyrite cement. Minor chalcopyrite-bearing
clasts are also observed (Figure
6b
).
The presence of multiple facies of polymictic breccias in TF24-123 and TF24-126 suggests a
complex magmatic-hydrothermal system during the late-stages of porphyry system development in
the Three Firs area. Modelling shows a general plunge of the breccia system to the southeast
towards a broad and untested high-chargeability anomaly (Figure 3). This anomaly will be tested for
a potential center of intrusion-hosted, porphyry-related mineralization and the source of the
mineralized clasts within the breccias.
Deerhorn Expansion Drilling
Drill hole DH24-125 at the Deerhorn deposit was designed to step-out 50 meters south of the
previously reported drill hole DH24-120, which intersected 1.16 g/t gold equivalent (0.91 g/t gold,
0.18% copper) over
86.0m
(see
September 3
rd
, 2024 news release, Table 1). DH24-125
intersected a broad zone of strong fracturing with associated clay alteration and local copper and
gold mineralization, up to 3.5% copper and 0.6 g/t gold (Figure 7). Further drilling up-dip from holes
DH24-120 and DH24-125 is required to evaluate the extension of mineralization southeast from the
main Deerhorn resource area.
Redgold Inaugural Drilling
Drilling at the Redgold project, contiguous and immediately north of the Woodjam district (Figure 1),
consisted of three holes, targeting the eastern and northern extension of porphyry-related copper
and gold mineralization at the East zone target (Figure 8). Hole RG24-15, a 135 meter step-out to
the southeast of hole RG12-11 (151.9 meters of 0.21% copper with 0.24 g/t gold
3
, see
May 12
th
,
2023 news release), intersected numerous intervals of anomalous copper and gold mineralization
highlighted by 30.0 meters of 0.15% copper and 0.13 g/t gold. These new drill results together with
recently acquired IP chargeability and resistivity data will be interpreted together to refine the
Redgold exploration model.
Next Steps
The 2024 drill program is now complete and assay results have been received from all the drill
holes. New drilling and geophysical data are currently being integrated with existing project-wide
data to prioritize targets for the next phase of exploration which may include drilling at the Three
Firs, Deerhorn, and Southeast targets.

Sampling, Chain of Custody, Quality Assurance and Quality Control
All drill core analytical results have been monitored through the Company's quality assurance and
quality control program (QA/QC). Drill core was sawn in half at Vizsla's dedicated and secure core
logging and processing facility in
Horsefly, BC
.
Half of the drill core was sampled and shipped by a bonded courier in sealed and secured woven
polyester bags to the ALS Global preparation facilities in
Kamloops, BC
. Core samples were
prepared using ALS standard preparation procedure PREP-31A which involves crushing the sample
to 70% less than 2mm, followed by a riffle split of 250g, and then a pulverised split to better than
85% passing 75 microns.
Following sample preparation, the pulps were sent to the ALS Global analytical laboratory in
North
Vancouver, BC
for analysis. ALS Global is registered to ISO/IEC 17025:2017 accreditations for
laboratory procedures.
Drill core samples were analyzed for 48 elements by ICP-MS on a 0.25-gram aliquot using a four-
acid digestion (method ME-MS61). Overlimit samples (>10,000 ppm Cu) were re-analyzed using an
ore-grade, four-acid digestion and ICP-AES finish (method ME-OG62). Gold was analyzed by fire
assay on a 30-gram aliquot with an AES finish (inductively coupled plasma atomic emission
spectroscopy - method Au-ICP21).
In addition to ALS Global laboratory QA/QC protocols, Vizsla implements a rigorous internal QA/QC
program that includes the insertion of field and lab duplicates, certified reference materials
(standards prepared by an independent lab) and blanks into the sample stream. Data verification of
the analytical results includes a statistical analysis of the QA/QC data. Results are considered
acceptable.
