VIZSLA COPPER DRILLS 237 METERS OF 0.51% CUEQ AT THE THIRA DISCOVERY; EXPANDS COPPER-MOLYBDENUM MINERALIZATION 200 METERS TO THE SOUTH

[20-October-2025]

VANCOUVER, BC, Oct. 20, 2025 /CNW/ - Vizsla Copper Corp. (TSXV: VCU) (OTCQB: VCUFF) (FRANKFURT: 97E0) ("Vizsla Copper" or the "Company") is pleased to announce results from the final four drill holes completed during the Phase 1 drill program at the Thira porphyry discovery, Poplar Project, central British Columbia.

HIGHLIGHTS

Near-surface, porphyry-related mineralization intersected in every drill hole: The final four drill holes (TH25-144, 145, 146, and 147) of Phase 1 drilling further demonstrate that porphyry-related copper-molybdenum mineralization extends for at least 800 meters east-west and for at least 500 meters north-south. Mineralization remains open in every direction.
Drill hole TH25-145 was collared 200 meters east of discovery drill hole TH25-138 and intersected:
- 237.3 meters of 0.51% copper equivalent* (CuEq, 0.36% Cu, 0.02% Mo, 1.19 g/t Ag, and 0.06 g/t Au, above a 0.2% Cu cutoff grade) from 117.7 meters down hole, including
- 77.0 meters of 0.55% copper equivalent* (0.43% Cu, 0.01% Mo, 1.48 g/t Ag, and 0.09 g/t Au, above a 0.4% Cu cutoff grade) from 124.0 meters down hole
- Mineralization remains open to the south.
Drill hole TH25-144 was drilled to the south from the TH25-138 pad and intersected:
- 240.0 meters of 0.39% copper equivalent* (0.29% Cu, 0.01% Mo, 1.08 g/t Ag and 0.06 g/t Au, above a 0.2% Cu cutoff grade) from 12.0 meters down hole, including
- 38.4 meters of 0.53% copper equivalent* (0.40% Cu, 0.01% Mo, 1.30 g/t Ag and 0.08 g/t Au, above a 0.3% Cu cutoff grade) from 193.0 meters down hole
- Mineralization remains open to the south.
Further targeted exploration activities are ongoing: Expanded soil geochemical and IP geophysical surveys are ongoing. The surveys are designed to identify additional porphyry centers and prioritize new drill targets across the ~8 by 2 kilometer, mostly till-covered Thira alteration corridor.
Planning is underway for a follow-up drill program: Planning is now underway for a significant Phase 2 drill program aimed at further evaluating the potential size and scale of the Thira porphyry-related copper-molybdenum system.

*Copper equivalent calculation (CuEq) uses metal prices of: Cu US$4.00/lb, Mo US$20.00/lb, Au US$2,000/oz and Ag US$22/oz and conceptual recoveries of Cu: 80%, Mo: 80%, Au: 70% and Ag: 65%. CuEq is provided for illustrative purpose only to show the combined grades of Cu, Mo, Au and Ag relative to copper price net of conceptual metallurgical recoveries. Composite intervals are calculated using length weighted averages above the cutoff grades noted above, with up to 10 meters of internal dilution. True thickness of the bulk-tonnage style, stockwork-hosted mineralization is unknown.

"Thira has delivered a new discovery of shallow, porphyry-related copper mineralization in an infrastructure rich area of BC mining country," commented Craig Parry, Executive Chairman and CEO. "Congratulations to our technical team on this excellent discovery at a time when the world needs more copper".

"I'm very pleased with the scale and tenor of the Thira discovery to date," commented Steve Blower, VP Exploration. "Strong porphyry-related mineral deposits commonly have large, mineralized footprints and very large alteration haloes. Based on our first phase of drilling on 200m spaced sections, it is clear, this alteration system has significant scale potential. I look forward to continuing to evaluate the ultimate size and grade of the porphyry system with the next drill program, and am optimistic that there may be more than one porphyry center within the 8-kilometer-long Thira alteration zone."

Testing the Limits of Thira

The recently completed Phase 1 drill program at Thira consisted of ten drill holes totalling over 4,500 meters. The angled drill holes tested a footprint of approximately 800 meters by 500 meters with results from all ten drill holes now reported. The widely-spaced, Phase 1 drill holes evaluated coincident geophysical and geochemical anomalies (see June 16^th, 2025 News Release) central to the Thira alteration corridor (Figure 1).

Drill holes TH25-144, 145, 146, and 147 evaluated the lateral and vertical extent of copper-molybdenum mineralization south of discovery hole TH25-138 (e.g., 345.3 meters of 0.43% CuEq* (0.31% Cu, 0.02% Mo, 1.1 g/t Ag and 0.05 g/t Au), see June 22^nd 2025 News Release). The drill holes were collared along a 500 meter east-west section with holes primarily drilled to the south, except for TH25-146 (Figure 2) which was drilled steeply to the north (Figures 2 to 6). These drill holes, as well as the six previously reported drill holes, have all intersected porphyry-related copper-molybdenum-silver-gold mineralization from top of bedrock (average 8.4 meters down hole) to bottom of holes (>400m). Strong mineralization (e.g., 77.0 meters of 0.55% CuEq* (0.43% Cu, 0.01% Mo, 1.48 g/t Ag, and 0.09 g/t Au) from 124.0 meters downhole in TH25-145, Table 1) consists of chalcopyrite-molybdenite bearing stockwork and multi-stage porphyry-related veins (A- and B-type) that crosscut intensely biotite altered volcanics and volcanic breccias and at least four phases of pre- and intra-mineral intrusions varying from plagioclase-biotite monzonite porphyries to equigranular biotite monzonite (Figure 7a to e). The intra-mineral variants have local truncated quartz veins and disseminated chalcopyrite. Zones of anhydrite veins and breccias with locally strong molybdenite mineralization associated with white mica-quartz alteration locally crosscut the main stage potassic alteration.

Results from the Phase 1 drill program at the Thira discovery highlight a zone of near-surface, porphyry-related copper-molybdenum-silver-gold mineralization that spans at least 800 meters east-west and at least 500 meters north-south. Mineralization remains open in every direction.

Additional Porphyry Targets

Further targeted exploration activities across the ~8 by 2 kilometer, mostly till-covered Thira alteration corridor (Figure 1) are ongoing. A comprehensive soil geochemical survey is now complete and over 35 line kilometers of IP (induced polarization) surveying is ongoing. The surveys, designed to define additional porphyry centers, will build on results from previous surveys (see October 8^th, 2024 News Release) that highlighted broad, coincident and open-ended multi-element soil geochemical and IP geophysical anomalies.

Next Steps at Thira

Lithological, geochemical and structural data from all holes are currently being integrated into a comprehensive 3D geological model that will inform the next round of drilling. Planning for an upcoming follow-up Phase 2 drill program is underway.

Poplar Project

The 44,200 hectare Poplar project in central BC covers Mesozoic aged arc-related volcanic, sedimentary and intrusive rocks considered prospective for porphyry-related copper and gold mineralization. In addition to the Thira target, the project also hosts the Poplar deposit, a near-surface porphyry-related copper and gold system. The Thira target is approximately 10 km south of the Poplar deposit. Vizsla Copper has the option to earn a 100% interest in the property through a series of expenditure commitments and annual cash payments until 2027.

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 near the Poplar Project

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, including Cu, Ag, Mo 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.
