Star Copper prepares for phase 2 drilling at Star

Executive Summary

• Star Copper Corp. reports that drill pad construction for its planned 2025 Phase 2 program uncovered significant surface mineralization, specifically a large supergene-enrichment zone with exceptional malachite.
• The first hole of Phase 2, designated G (S-056), is positioned to test targets south of the Star fault zone, aiming to extend the copper footprint southwest and evaluate hypogene Cu/Au zones at depth.
• The company has established access to the Copper Creek project area, a high-priority target located 2.5 km southeast of Star Main, where mapping and sampling are underway to inform future drilling.

Key Details

• Surface Discovery: During drill pad construction for Phase 2, crews uncovered the top of a large supergene-enrichment zone featuring exceptional malachite mineralization.
• Hole G (S-056) Specifications:
  • Location: Approximately 130 meters south of Hole D (S-053B) and 100 meters west of Hole F (S-055).
  • Coordinates: UTM 339,691E/6,458,142N, elevation 1,050 meters.
  • Orientation: Azimuth 000 degrees, dip negative 75 degrees.
  • Planned Depth: 500 meters.
  • Objective: To pierce near-surface supergene copper mineralization (malachite/azurite) and step down into the hypogene domain (chalcopyrite). It aims to cross a corridor of mineralized quartz monzodiorite (QMD) identified in Hole F and evaluate a hypogene Cu ± Au zone intersected in historical hole S-040 at depths greater than 300 meters.
  • Geological Context: Positioned to further evaluate the southwest extension of magnetic and induced polarity anomalies and clarify grade-control architecture in the footwall of the Star fault zone.
• Copper Creek Project Update:
  • Location: 2.5 kilometers southeast of Star Main.
  • Status: Ground access established; mapping and sampling of a ~2 km by 1.5 km Cu ± Au soil anomaly are underway.
  • Significance: Validated historical exploration records; represents a high-priority target that may be the southeastern extent of a broader mineralized trend extending northwest toward the Main zone.
  • Future Plans: Insights from current fieldwork will inform potential drilling in the later stages of Phase 2.
• Strategic Context: Phase 2 marks a transition from Phase 1's structural mapping to targeted drilling designed to advance continuity and scale across the Star Main deposit.

Notable Quotes

• Darryl Jones, CEO: "By retesting the target that hole D could not fully evaluate and by stepping west from hole F, our upcoming hole G is positioned to confirm and extend the copper footprint of Star Main to the southwest, clarify grade-control architecture in the footwall of the Star fault zone and strengthen links between oxidation profiles, potassic alteration and hypogene sulphide mineralization. As the first hole of phase 2, it marks the transition from phase 1's mapping of structure and alteration to targeted drilling that advances continuity and scale across Star Main."
