Star Copper Advances Satellite Target Located 1.5 Km from Star Main Deposit; Arranges Non-Brokered Flow Through Private Placement

Executive Summary

• Star Copper completed its inaugural drill hole (SN‑25‑001) at the newly defined “Star North” target, reaching a depth of 402 m and providing the first subsurface data for this IP chargeability high.
• Assay results are still pending; however, core observations show favorable alteration, quartz‑sulphide veining and disseminated chalcopyrite consistent with a potential second mineralized centre on the Star Project.
• The company announced a non‑brokered flow‑through private placement to raise up to C$2.5 million (2,118,644 units at C$1.18 per unit) to fund Canadian exploration expenses on the Star Project.

Key Details

• Drill Hole SN‑25‑001 – Collar: 340487 E, 6459084 N; elevation 1,163 m; azimuth 131°; dip ‑45°; total depth 402 m; completed 6 Nov 2025.
• Target Characteristics – ~500 m × 1,000 m copper‑in‑soil anomaly coincident with a strong IP chargeability high; surface sampling yielded up to 17.6 % Cu and 0.942 g/t Au (sample AA002620).
• Core Logging Observations – Volcanic host units intruded by dykes, multiple fracture generations, quartz‑sulphide veining, variable alteration from propylitic to patchy potassic; fine disseminated chalcopyrite and veinlet occurrences noted.
• Implications – Data will be used to refine the 3‑D mineralization model for additional drilling in 2026; suggests Star North could be a second centre within a broader porphyry cluster.
• Assay Status – Results from SN‑25‑001 (and pending assays from Star Main and Copper Creek holes) are not yet released; will be disclosed after QA/QC review.
• Financing Terms – Up to C$2,500,000 gross proceeds; 2,118,644 FT Units at C$1.18 each. Each unit = one flow‑through common share + one warrant (exercise price $1.20, 24‑month term). Statutory 4‑month hold period applies.
• Use of Proceeds – To fund “Canadian exploration expenses” that qualify as flow‑through critical mineral mining expenditures on the Star Project.
• Finder’s Fees & Conditions – Company may pay finder’s fees; offering subject to customary closing conditions and required approvals.

Notable Quotes

“As the inaugural subsurface test of Star North, SN‑25‑001 provides the first drill‑hole look beneath compelling coincident geochemical and geophysical anomalies and will be integral to refining the 3‑D mineralization model for follow‑up drilling in 2026.” – Darryl Jones, CEO & President

Materiality Assessment: Non‑Material – Positive (the announcement adds operational insight and financing but does not contain definitive resource or earnings impact).
