Star Copper Kicks Off Inaugural Drilling at Star North Target

Executive Summary

• Star Copper commenced drilling on its inaugural hole SN‑25‑001 at the newly defined “Star North” target, located ~1 km NE of the Star Main area.
• Surface sampling from 119 rock chips returned high-grade copper (up to 17.6 % Cu) and notable gold (0.942 g/t Au), supporting the presence of two distinct copper mineralisation styles.
• The hole is currently at 144 m depth of a planned 400 m (≈1,300 ft) and will test coincident magnetic and IP chargeability anomalies to evaluate the relationship between geophysics, alteration and sulphide distribution.

Key Details

• Hole SN‑25‑001 – UTM 340,487E / 6,459,084N; elevation 1,163 m; azimuth 131°; dip ‑45°. Planned depth 400 m; current depth 144 m.
• Target Geology:
• Style 1 – semi‑massive chalcopyrite veins/stringers in silicified brecciated volcanic units.
• Style 2 – fine to blebby disseminated chalcopyrite ± pyrite in quartz monzodiorite/monzonite with potassic alteration.
• Surface Sampling Highlights (119 samples):
• Sample AA002620 – 17.6 % Cu, 0.942 g/t Au (Easting 340628, Northing 6459062).
• Sample AA002628 – 3.21 % Cu, 0.027 g/t Au (Easting 340525, Northing 6458995).
• Statistical Summary (119 samples):
• Cu % – Mean 0.482 %, Median 0.019 %, Max 17.6 %.
• Au (g/t) – Mean 0.038 g/t, Median 0.005 g/t, Max 0.942 g/t.
• Geophysical Context: Star North sits within a 500 m × 1,000 m soil Cu‑in‑soil anomaly and coincident IP chargeability high; similar signatures at Star Main previously correlated with strong historic drill intercepts.
• Program Objective: Evaluate the “heart” of the target by intersecting magnetic and IP anomalies, testing alteration zones, and defining sulphide distribution for potential resource expansion as a second copper centre.
• QA/QC Protocols: HQ/NQ diamond core; 5 % certified reference materials, blanks & duplicates; analysis by Bureau Veritas (ISO/IEC 17025) using multi‑element ICP‑ES/MS and fire assay for Au.
• Qualified Person: Jeremy Hanson, P.Geo., independent contractor, NI 43‑101 qualified, reviewed and approved the technical content.

Notable Quotes

“Kicking off drilling at Star North marks a major milestone for our 2025 program,” said CEO Darryl Jones. “With compelling surface results and robust geophysical and geochemical signatures, this first hole is an important step toward demonstrating a second copper center alongside our Star Main location.”
