Star Copper talks mineralized zone at Copper Creek

Executive Summary

• Star Copper confirmed the continuity of historic copper mineralization at its Copper Creek satellite target, located 2.5 km southeast of the Star Main zone, through the completion of its first modern drill hole (CC-25-001) in 2025.
• The drilling campaign included mapping, soil sampling, and the initial drill test, which intersected heavily fractured and sheared lithic tuffs and sediments with intense chlorite-epidote alteration and observed chalcopyrite mineralization.
• The company plans to use these results to guide the 2026 campaign, which will include confirmatory drilling on the Copper Creek target and testing of a northern geophysical target to expand the project scope.

Key Details

• Drill Hole ID: CC-25-001
• Location: Copper Creek satellite target, 2.5 km southeast of Star Main.
• Coordinates: 341181E, 6456422N, 902 metres above sea level.
• Drill Parameters: Azimuth 262 degrees, dip -45 degrees, total depth 151 metres.
• Geological Intersections:
  • Sequences of heavily fractured and sheared andesite lithic tuffs.
  • Dark, cherty laminated sediments.
  • Common brecciation and zones of intense chlorite-epidote alteration.
• Mineralization Observations:
  • Chalcopyrite observed in discrete intervals as quartz-epidote vein material.
  • Semi-massive pyrrhotite-pyrite-chalcopyrite associated with shear zones.
• Context: The hole was drilled west to evaluate and characterize copper-gold mineralization reported in 1970s drilling (ARIS 80026) within a wider 550-metre-by-1,000-metre copper- and gold-in-soil anomaly.
• 2025 Campaign Activities:
  • Established trail access from Star Main.
  • Completed a 32-sample soil grid over a strong IP chargeability high in the upper Copper Creek drainage.
  • Conducted detailed mapping with 36 rock samples within the Copper Creek gully system.
• Future Plans:
  • Compiling results from the 2025 fieldwork.
  • Aiming to report assay results from CC-25-001 and related sampling.
  • Planning confirmatory drilling on the Copper Creek target for 2026.
  • Accessing the northern geophysical target to plan additional drilling.

Notable Quotes

• "Collectively, the 2025 campaign mapping, soils sampling and first drill hole confirms continuity with historic copper mineralization and meaningfully advances Copper Creek toward identifying the porphyry-style source driving the drainage-scale anomalies. The drilling data significantly increases the overall scope of our Star project and offers intriguing early indications of a regional large-scale copper deposit." — Darryl Jones, CEO
