VIZSLA COPPER INTERSECTS MINERALIZED BRECCIA IN EXPLORATION DRILLING NEAR THE THREE FIRS TARGET, WOODJAM PROJECT

 

 

 

 

 

Vizsla Copper Corp. (TSX-V: VCU) (OTCQB: VCUFF) (FRANKFURT: 97E0) 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 3rd, 2024 and September 9th, 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 30th, 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 3rd, 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 gold3, see May 12th, 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. 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.
