Vizsla Copper Corp. (TSX-V: VCU) (OTCQB: VCUFF) (FRANKFURT: 97E0) is pleased to announce the discovery of a significant copper-molybdenum porphyry-related system at the Thira target. Thira is located on the Poplar Project in central British Columbia. The drill program has been expanded with over 5,000 meters now planned at the Thira target area.

HIGHLIGHTS

• Thira Discovery: The first drill hole of the program, TH25-138, intersected near-surface, porphyry-related copper-molybdenum-silver-gold mineralization throughout its entire ~500 meter length:
  • 499.3 meters of 0.39% copper equivalent* (CuEq, 0.28% Cu, 0.02% Mo, 1.01 g/t Ag and 0.04 g/t Au, above a 0.1% CU cutoff grade) from 10.7 meters down hole, including
  • 345.3 meters of 0.43% copper equivalent* (0.31% Cu, 0.02% Mo, 1.10 g/t Ag, and 0.05 g/t Au, above a 0.2% Cu cutoff grade) from 10.7 meters down hole, including
  • 78.25 meters of 0.46% copper equivalent* (0.40% Cu, 0.01% Mo, 1.49 g/t Ag, and 0.09 g/t Au, above a 0.3% Cu cutoff grade) from 21.75 meters down hole, and including
  • 53.0 meters of 0.53% copper equivalent* (0.35% Cu, 0.04% Mo, 1.28 g/t Ag, and 0.04 g/t Au, above a 0.3% Cu cutoff grade) from 140.0 meters down hole
• Drilling is Ongoing: The drill rig is currently evaluating the western extent of strong copper-molybdenum mineralization intersected in discovery hole TH25-138.
• Program Expansion: Over 5,000 meters of drilling are now planned at Thira to systematically advance the discovery.

“The Thira discovery marks a significant milestone for Vizsla Copper” commented Craig Parry, Executive Chairman and CEO. “Considering the shallow mineralization, large remaining untested anomaly, excellent road access, and gentle topography, this result has extraordinary potential to become a significant discovery in central British Columbia. This tremendous outcome is a product of the hard work, skill and effort applied by the entire Vizsla Copper team. With the strong long-term fundamentals for the copper market, this is excellent timing to announce a new copper discovery.”

“Our technical team, led by Dr. Chris Leslie (Technical Advisor) and Kevin Pinkerton (Senior Geologist), have done a tremendous job identifying the Thira target with the skillful application of geology, geochemistry and geophysics,” commented Steve Blower, VP Exploration. “I’m encouraged that our discovery drill hole, TH25-138, has intersected significant multi-stage stockwork veining with copper-molybdenum mineralization along its entire 500m length, which suggests that the system is large and robust.”

Thira Porphyry Discovery

Drilling at Thira is designed to target copper-molybdenum mineralization across a broad, untested and concealed target area (Figure 2, see June 16^th, 2025 News Release). Besides one historical percussion drill hole (P95-05) completed in 1995 on the edge of the target area (0.18% Cu and 0.022% Mo throughout its 67 meter length²), the strongest coincident anomalies (e.g., high-chargeability, magnetic, MobileMT, and multi-element soil geochemical) have never been drilled (Figure 2).

The first hole of the current drill program (and the first hole ever completed by Vizsla Copper on the Poplar Project), TH25-138, was drilled towards 360 with a -80 dip. Following only 10 meters of overburden (Figures 3 and 4), TH25-138 intersected porphyry-related copper-molybdenum mineralization at the top of bedrock, extending to the bottom of the hole at 510 meters (e.g., 499.3 meters of 0.39% copper equivalent* (0.28% Cu, 0.02% Mo, 1.01 g/t Ag and 0.04 g/t Au), Table 1, Figure 3). Mineralization consists primarily of quartz-chalcopyrite-molybdenite stockwork and disseminated chalcopyrite associated with locally strong potassium feldspar + biotite alteration (Figure 4). Stockwork zones and multi-stage porphyry-related veins (A- and B-type) and vein-dykes crosscut at least three phases of pre- and intra-mineral intrusions varying from plagioclase-biotite monzonite porphyries to equigranular biotite monzonite (Figure 4). Zones of anhydrite-chalcopyrite-molybdenite veins and stockworks associated with white mica-quartz alteration crosscut the main stage potassic alteration (Figure 4). The strongest copper mineralization (e.g., 78.25 meters of 0.40% Cu from 21.75 meters down hole and 17.0 meters of 0.40% Cu from 244 meters down hole, Table 1) is associated with zones of intense biotite alteration and a higher-frequency of quartz-chalcopyrite veins and stockwork. Additional drilling is evaluating the extent and structural controls on this style of higher-grade mineralization.

The nature of the porphyry-related, stockwork-controlled copper-molybdenum mineralization in discovery hole TH25-138 suggests the hole intersected a new and previously unknown porphyry center. The announced 2,400 meter drill program has therefore been expanded to over 5,000 meters with drilling aimed at investigating the lateral and vertical extent of the porphyry system.

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 Poplar deposit is approximately 10 km north of the Thira target. 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 Nadina Lake, 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.
