The five holes (TH25-139, 140, 141, 142 and 143) build on discovery hole TH25-138 and demonstrate that porphyry-related copper-molybdenum-silver-gold mineralization extends for at least 800 meters along an east-west section and remains open in every direction. Results from the remaining four holes completed in Phase 1 drilling are pending.

HIGHLIGHTS

• Near-surface, porphyry-related mineralization intersected in every hole: Holes TH25-139, 140, 141, 142 and 143 were mineralized along their entire >400 meter lengths and tested a ~800 meter east-west section.

*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.

“Based on these drill results, it is clear that our Thira porphyry discovery has significant scale potential” commented Craig Parry, Executive Chairman and CEO. “Mineralization intersected in these new drill holes, together with our previously announced discovery hole are part of a near-surface porphyry-related system that spans at least 800 meters east-west and is open in every direction.

Defining the Potential Scale of Thira

The recently completed Phase 1 drill program at Thira consisted of 10 drill holes totalling over 4,500 meters. The angled holes tested a footprint of approximately 800 meters by 500 meters with results from six holes, all collared on the same east-west section (78100 N, holes TH25-138, 139, 140, 141, 142 and 143; Figure 3), now reported. The widely-spaced, Phase 1 drill holes tested coincident geophysical and geochemical anomalies (see June 16^th, 2025 News Release) central to the Thira alteration corridor (Figure 1).

Holes TH25-139 and TH25-140 were collared approximately 200 meters and 300 meters east 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) respectively. Holes TH25-141 and 142 were collared a further 100 meters east, approximately 400 meters east of hole TH25-138. Hole TH25-143 was collared on the same pad as TH25-138 but drilled to the west. The holes were designed to test the lateral and vertical extents of porphyry-related copper-molybdenum mineralization intersected in TH25-138.

All six now reported drill holes intersected porphyry-related copper-molybdenum-silver-gold mineralization from top of bedrock (average 8.1 meters down hole) to bottom of holes (>400m). The strongest mineralization (e.g., 74.0 meters of 0.57% CuEq (0.37% Cu, 0.028% Mo, 0.075 g/t Au, and 1.23 g/t Ag) from 138.0 meter downhole in TH25-142, 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 three phases of pre- and intra-mineral intrusions varying from plagioclase-biotite monzonite porphyries to equigranular biotite monzonite. 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 six reported drill holes at Thira document a zone of porphyry-related copper-molybdenum-silver-gold mineralization that spans at least 800 meters east-west. The potential scale of the Thira porphyry system is highlighted by hole TH25-140 that intersected mineralization 600 meters to the east of hole TH25-138, hole TH25-143 that intersected mineralization 200 meters to the west of TH25-138 and hole TH25-139 that bottomed in strong copper-molybdenum mineralization (e.g., 19.0 meters of 0.44% CuEq (0.24% Cu, 0.036% Mo, 0.02 g/t Au, and 0.80 g/t Ag), Table 1). Mineralization remains open in every direction.

Next Steps at Thira

Results from the remaining 4 holes completed during the Phase 1 drill program will be released once assay results are returned from the lab, compiled and interpreted. Lithological, geochemical and structural data from all holes will be integrated into a comprehensive 3D model that will inform the next round of drilling.

Generating Additional Porphyry Targets

Further targeted exploration activities across the ~8 by 2 kilometer, mostly till-covered Thira alteration corridor (Figure 1) have commenced with over 1,500 soil samples and over 35 line kilometers of IP (induced polarization) surveying now underway. 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.

Table 1. Assay Results

*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$22/oz and conceptual recoveries of Cu: 80%, Mo: 80%, Au: 70% and Ag: 65%. Metallurgical test work has not been performed on core from Thira, therefore it is uncertain which metals would report to potential concentrates – recoveries are conceptual in nature. CuEq is provided for illustrative purpose only to show the combined grades of Cu, Mo, Au and Ag relative to copper price net of conceptual metallurgical recoveries. CuEq% = Cu% + (Au g/t x (Au recovery / Cu recovery) x [Au price US$/oz ÷ 31] / [Cu price US$/lb x 22.04623]) + (Ag g/t x (Ag recovery / Cu recovery) x [Ag price US$/oz ÷ 31] / [Cu price US$/lb x 22.04623] + (Mo grade % x (Mo recovery / Cu recovery) x [Mo price US$/lb x 2204.623] / [Cu price US$/lb x 2204.623]). 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.

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 the property.

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.
