Star Copper begins drilling at Star North target

Executive Summary

• Star Copper Corp. has commenced drilling on the inaugural hole (SN-25-001) at its Star North target, located one kilometre northeast of the Star Main project area.
• The company highlights compelling surface results from the 2025 season, including high-grade grab samples containing up to 17.6% copper and 0.942 g/t gold.
• The drilling program aims to test a high-impact target with defined geochemical and geophysical anomalies, seeking to establish a nested porphyry cluster model alongside the existing Star Main location.

Key Details

• Drilling Status: Inaugural hole SN-25-001 is currently drilling at a depth of 144 metres.
• Hole Specifications:
  • Location: UTM 340,487E/6,459,084N; elevation 1,163 metres.
  • Orientation: Azimuth 131 degrees; dip minus 45 degrees.
  • Planned Depth: 400 metres.
• Target Characteristics: Star North hosts two documented copper styles: semi-massive chalcopyrite in veins/stringers within silicified/brecciated volcanic units, and fine to blebby disseminated chalcopyrite plus pyrite in quartz monzodiorite/monzonite with potassic alteration.
• Geophysical Context: The target features a well-defined 500-metre-by-1,000-metre soil geochemical anomaly and a coincidental IP (induced polarization) chargeability high. Historic drilling at the nearby Star Main target correlated chargeability highs with the best results.
• 2025 Surface Sampling Results:
  • Crews completed detailed mapping and collected 119 rock samples.
  • Sample AA002620: 17.6% copper and 0.942 g/t gold from semi-massive chalcopyrite in highly altered augite-plagioclase porphyry.
  • Sample AA002628: 3.21% copper.
• Strategic Objective: The company aims to demonstrate a second copper centre alongside Star Main, evaluating the relationship between geophysics, alteration, and sulphide distribution at depth.

Notable Quotes

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