Star Copper Receives Excellent Preliminary Assay Results and Applauds Proposed Nation-Building Golden Triangle Investment

Executive Summary

• Star Copper Corp. announced preliminary results from the first three drill holes (S-050, S-051, S-052) of its Phase 1 drill program at the Star Project in British Columbia's Golden Triangle.
• The results confirm a broad near-surface supergene copper enrichment blanket at Star Main, covering approximately 300 x 250 m to a depth of 100 m, with significant intercepts of copper and gold.
• Phase 2 drilling has commenced to expand the shallow supergene footprint and confirm the oxide footprint at surface, which remains open to the northeast and southwest.

Key Details

• Hole S-051: Intersected 226.54m at 0.67% CuEq (0.42% Cu & 0.25 g/t Au) from 14m.
  • Included 90m at 1.06% CuEq (0.59% Cu & 0.47 g/t Au) from 14m.
  • Included 40m at 1.56% CuEq (0.89% Cu & 0.68 g/t Au) from 37m.
• Hole S-050: Intersected 93m at 0.91% CuEq (0.55% Cu & 0.37 g/t Au) from 8m.
  • Included 32m at 1.21% CuEq (0.76% Cu & 0.45 g/t Au) from 15m.
• Hole S-052: Intersected 397m at 0.37% CuEq (0.25% Cu & 0.11 g/t Au) from 29m.
  • Included 228m at 0.51% CuEq (0.33% Cu & 0.17 g/t Au) from 17m.
  • Included 90m at 0.74% CuEq (0.51% Cu & 0.23 g/t Au) from 29m.
• Geological Model: Results confirm a transition from supergene mineralization to hypogene zonation below fault structures, showing vertical and lateral continuity at depth.
• Future Plans: Phase 2 drilling is underway to expand the supergene footprint and test nested porphyry cluster deposit models at Copper Creek and Star North.
• Assay Methodology: Copper equivalent (CuEq) calculated using metal prices of Cu US$4.00/lb and Au US$3000/oz, with conceptual recoveries of 80% for both metals.
• QA/QC: Samples analyzed by Bureau Veritas Laboratories; QA/QC protocols include certified reference materials, blanks, and field duplicates, verified by Qualified Person Jeremy Hanson, P. Geo.

Notable Quotes

• "Recent announcements by the Canadian government regarding the fast-tracked mine expansion at the nearby Red Chris Copper-Gold Project as one of five 'nation-building' projects has captured the interest and attention of our entire team... the early returns from our Phase 1 drilling have us excited about the potential for the Star Project to emerge as a prominent copper district in the province." — Darryl Jones, CEO
• "The timing of this excellent economic message comes just as we have received strong initial results validating our geologic model of a laterally extensive near-surface supergene copper enriched blanket over hypogene chalcopyrite at depth which underscores the scale and potential at Star Main." — Darryl Jones, CEO
