Star Copper completes first drill hole at Star North

Executive Summary

• Star Copper Corp. completed the inaugural drill hole (SN-25-001) at its Star North target, located approximately 1 km northeast of the Star Main deposit, marking the final hole of the 2025 exploration program.
• The company announced a non-brokered flow-through private placement for gross proceeds of up to $2.5 million, priced at $1.18 per unit, to fund Canadian exploration expenses on the Star project.
• While assay results for SN-25-001 are pending, core logging indicates encouraging geological features including chalcopyrite disseminations, quartz-sulphide veining, and potassic alteration consistent with a porphyry system.

Key Details

• Drilling Operations:
  • Hole ID: SN-25-001 (13th and final hole of 2025 program).
  • Location: Star North target, ~1 km northeast of Star Main zone, British Columbia.
  • Collar Coordinates: 340487E, 6459084N; Elevation: 1,163 metres.
  • Drill Parameters: Azimuth 131 degrees, Dip -45 degrees, Total Depth 402 metres.
  • Completion Date: November 6, 2025.
• Geological Observations (Core Logging):
  • Stratigraphy consistent with surface mapping: volcanic host units intruded by dykes, fracturing, brecciation, and quartz-sulphide veining.
  • Alteration ranges from propylitic to patchy potassic (K-feldspar) alteration.
  • Chalcopyrite observed as fine disseminations and within quartz-sulphide veinlets/stringers, locally accompanied by pyrite and magnetite.
  • Observations suggest a transition from structurally prepared volcanic units to intrusive porphyritic phases.
• Surface Geochemistry & Sampling:
  • Star North features a 500m x 1,000m copper-in-soil anomaly coincident with a strong IP chargeability high.
  • Sample AA002620: 17.6% Copper and 0.942 g/t Gold.
  • Sample AA002628: 3.21% Copper.
  • Samples collected from semi-massive chalcopyrite in highly altered augite-plagioclase porphyry.
• Financing Details:
  • Type: Non-brokered private placement of flow-through units.
  • Gross Proceeds: Up to $2.5 million.
  • Units Offered: Up to 2,118,644 flow-through units.
  • Price: $1.18 per flow-through unit.
  • Warrant Terms: Each unit includes one flow-through common share purchase warrant.
    • Exercise Price: $1.20 per warrant share.
    • Term: 24 months from issuance.
    • Note: Warrant shares do not qualify as flow-through shares.
  • Use of Proceeds: Incur Canadian exploration expenses classified as flow-through critical mineral mining expenditures on the Star project.
  • Hold Period: Statutory four-month hold period applies.
• Future Plans:
  • Assay results for SN-25-001, Copper Creek, and Star Main are pending (11 holes pending total).
  • Results will be used to refine the 3-D mineralization model for follow-up drilling in 2026.
  • Star North is viewed as a potential second mineralized center within a broader porphyry cluster framework.
