VIZSLA COPPER DRILLS 298 METERS OF 0.49% CUEQ, EXPANDING THE THIRA DISCOVERY, CENTRAL BRITISH COLUMBIA

Vizsla Copper reported initial assay results from two of 17 Phase 2 holes at the Thira porphyry Cu-Mo discovery, Poplar Project, central BC. The release leads with TH26-170, a deep hole collared on the northern side of Thira and drilled southwest at -66 degrees.

• TH26-170 returned 297.8 m at 0.49% CuEq from 386.0 m to 683.8 m downhole, above a 0.20% Cu cutoff. Primary grade is 0.29% Cu, 0.027% Mo, 0.03 g/t Au and 1.6 g/t Ag.
• Within that, 52.2 m at 0.64% CuEq from 563.8 m to 616.0 m above a 0.30% Cu cutoff. Primary grade is 0.43% Cu, 0.029% Mo, 0.03 g/t Au and 1.4 g/t Ag.
• Within that, 28.5 m at 0.71% CuEq from 573.0 m to 601.5 m above a 0.40% Cu cutoff. Primary grade is 0.50% Cu, 0.028% Mo, 0.034 g/t Au and 1.55 g/t Ag.
• TH26-170 also reported broader lower-cutoff intervals: 83.4 m at 0.22% CuEq from 129.6 m, 46.6 m at 0.28% CuEq from 257.0 m, and 366.0 m at 0.45% CuEq from 345.0 m, all at a 0.10% Cu cutoff.
• TH26-169 returned 243.5 m at 0.22% CuEq from 266.5 m to 510.0 m above a 0.10% Cu cutoff. Primary grade is 0.14% Cu, 0.01% Mo, 0.016 g/t Au and 0.49 g/t Ag.
• The company says Phase 2 is complete: over 8,800 m in 17 holes along the Thira alteration corridor. Only TH26-170 and TH26-169 are reported; seven Thira holes, six Camp Lake holes and two Copper Pond holes are pending.
• CuEq uses Cu US$4.00/lb, Mo US$25.00/lb, Au US$2,500/oz and Ag US$25/oz, with conceptual recoveries of Cu 80%, Mo 80%, Au 70% and Ag 65%. Metallurgical testwork has not been performed on Thira core.
• True thickness is stated to be unknown. The mineralized footprint is described as approximately 800 m by 900 m, now extending from top of bedrock to at least 670 m below surface, and open at depth.

Vizsla Copper is an explorer/development-stage company with no revenue, a market capitalization of roughly C$87 million based on the implied post-Agnico share count, and a portfolio that now includes Palmer, Poplar/Thira, Woodjam, Copperview, Miller, Delta and Helm Bay. Thira is pre-resource. A 297.8 m at 0.49% CuEq porphyry intercept is meaningful for the geological model, but it is not a resource-defining or economic milestone.

The result is genuinely new in one respect: it extends mineralization to at least 670 m below surface and remains open at depth. That grows the vertical dimension of the Thira system. But the grade and width are in line with prior Thira holes, not materially better. The 800 m by 900 m footprint was already known; the release does not establish a new porphyry centre, a new high-grade zone with assays, or a resource.

The stock is near its 52-week low at C$0.77, down from C$2.55 in January 2026. The prior Thira anchor results are therefore not embedded in the current price; the market is not pricing this release for perfection. That supports a positive, rather than negative, read. It does not make the release transformational. The appropriate expected share-price impact is modest positive, with the larger re-rating dependent on the pending seven Thira holes, Camp Lake and Copper Pond assays, and ultimately metallurgy and a resource.

Vizsla Copper is a Vancouver-based critical-minerals explorer and developer. It has no revenue and is funded by equity. Its main assets are: - Palmer VMS project, southeast Alaska: 100% owned after the December 2025 Constantine acquisition. Indicated resource of 4.77 Mt at 1.69% Cu and 5.17% Zn, plus Inferred 12.0 Mt at 0.57% Cu and 3.92% Zn, with silver, gold and barite. The 2026 programme is about 12,250 m, with a resource update planned for Q1 2027. - Poplar/Thira, central BC: porphyry Cu-Mo discovery. Thira has a defined footprint of about 800 m by 900 m and mineralization to at least 670 m depth. About 20,000 m were drilled at Poplar in 2026. No resource. - Woodjam, central BC: porphyry-related Cu-Au project, including the Deerhorn deposit. Deerhorn has a historical inferred estimate of 32.8 Mt at 0.22% Cu and 0.49 g/t Au; this is historical and not treated as current. - Copperview, south-central BC: M5 porphyry target, inaugural 2,000 m drill programme ongoing. - Miller, central BC: 25,274 ha staked near Centerra’s Mount Milligan mine; early-stage. - Delta VMS and Helm Bay gold, Alaska: acquired from Agnico Eagle in October 2026. Delta has a historical 2006 estimate of 15.4 Mt at 0.6% Cu, 1.6% Pb, 3.8% Zn, 62 g/t Ag and 1.7 g/t Au, not a current resource. Agnico became largest shareholder at about 19.99%, potentially about 22.0%. - Financial backdrop, prior-period context: Q1 FY2027 ended July 31, 2026, with a net loss of about C$2.95 million, cash of about C$22.47 million, no revenue and exploration and evaluation assets of about C$65.58 million. The share count in that filing was about 90.1 million before the Agnico share issuance; the market capitalization above uses the roughly 112.7 million shares implied by Agnico’s 19.99% post-closing stake.
