VIZSLA COPPER EXPANDS FOOTPRINT OF STRONG COPPER-MOLYBDENUM MINERALIZATION AT THE THIRA DISCOVERY; DRILLS 264 METERS OF 0.43% CUEQ IN 400 METER STEP-OUT HOLE

Executive Summary

• Vizsla Copper reported assay results from five new drill holes (TH25‑139 to TH25‑143) that extend the known copper‑molybdenum‑silver‑gold porphyry system at Thira to at least 800 m east‑west and remain open in all directions.
• The most significant intercepts include 324 m @ 0.39 % CuEq (TH25‑142) and 429 m @ 0.28 % CuEq (TH25‑140), with multiple higher‑grade sub‑intervals (>0.4 % CuEq).
• The results support a large, near‑surface bulk‑tonnage target and justify continued exploration, including additional soil sampling, IP surveys, and the next phase of drilling.

Key Details

• Hole TH25‑142 (collared 400 m east of discovery hole) – 324.0 m @ 0.39 % CuEq (0.27 % Cu, 0.014 % Mo, 0.90 g/t Ag, 0.05 g/t Au) from 6 m depth; includes 264.0 m @ 0.43 % CuEq (0.30 % Cu, 0.016 % Mo, 0.98 g/t Ag, 0.06 g/t Au) from 51 m depth.
• Hole TH25‑140 (collared 300 m east) – 429.0 m @ 0.28 % CuEq (0.20 % Cu, 0.01 % Mo, 0.71 g/t Ag, 0.03 g/t Au) from 6 m depth; includes 93.1 m @ 0.39 % CuEq (0.28 % Cu, 0.012 % Mo, 0.96 g/t Ag, 0.06 g/t Au) from 187.9 m depth.
• Hole TH25‑143 (drilled west) – 411.7 m @ 0.27 % CuEq (0.20 % Cu, 0.009 % Mo, 0.76 g/t Ag, 0.03 % Au) from 14.3 m depth; includes 122.0 m @ 0.36 % CuEq (0.25 % Cu, 0.012 % Mo, 1.1 g/t Ag, 0.05 g/t Au).
• Hole TH25‑139 – multiple intervals, highest sub‑interval 19.0 m @ 0.44 % CuEq (0.24 % Cu, 0.036 % Mo, 0.02 g/t Au, 0.80 g/t Ag).
• All five holes intersected mineralization over their full >400 m lengths; mineralization remains open to the east (TH25‑142) and west (TH25‑143).
• Phase 1 drilling now totals 10 holes / >4,500 m, covering an ~800 m × 500 m footprint.
• Remaining four Phase 1 holes have assays pending; results will be released when available.

Notable Quotes

“Based on these drill results, it is clear that our Thira porphyry discovery has significant scale potential,” said Craig Parry, Executive Chairman and CEO. “Mineralization intersected in these new drill holes…spans at least 800 meters east‑west and is open in every direction.”

Materiality Assessment: Material – Positive (the extensive, near‑surface copper‑molybdenum system materially enhances the company’s exploration outlook.)
