Star Copper begins drilling at Copper Creek target

Executive Summary

• Star Copper Corp. has commenced first-pass drilling at the Copper Creek satellite target, located approximately 2.2 km southeast of the Star Main project within the company's flagship Star project in northwestern British Columbia.
• The initial campaign consists of two planned holes, each approximately 400 metres in length, designed to confirm historic mineralized intervals and test high copper-gold soil and rock XRF anomalies coincident with strong IP chargeability.
• The target was refined using modern geophysics, soil analysis, and detailed mapping, with field crews identifying widespread copper at surface (chalcopyrite, malachite, and azurite) across upper and lower gullies.

Key Details

• Location: Copper Creek satellite target, ~2.2 km southeast of Star Main, Star Project, Golden Triangle, British Columbia.
• Drilling Status: First-pass drilling has commenced; drill is "turning."
• Program Scope: Two-hole program, approximately 400 metres per hole.
• Objectives:
  • Confirm historic mineralized intervals from earlier drilling.
  • Test high copper-gold soil and rock XRF anomalies coincident with strong IP chargeability across the east-west structural corridor in the lower gully.
• Geological Context:
  • Copper Creek comprises two copper-in-soil and gold-in-soil trends coinciding with IP chargeability and magnetic highs.
  • Widespread copper at surface noted in upper and lower gullies.
  • Lower gully hosts a complex, broadly east-west structural corridor focusing mineralization.
• Historic Work: Includes prospecting, trenching, limited 1970 drilling, and 2013 geophysical/geochemical surveys. Data recently reinterpreted with 3-D inversion and Leapfrog modelling.
• QA/QC Protocols:
  • HQ- and NQ-sized diamond drill core.
  • Samples shipped to Bureau Veritas Laboratories (ISO/IEC 17025-accredited).
  • Analytical procedures: Multielement ICP-ES/MS following four-acid digestion; gold/precious metals by fire assay with atomic absorption or ICP finish.
  • QA/QC includes minimum 5% certified reference materials, blanks, and field duplicates.
  • Qualified Person: Jeremy Hanson, PGeo.
• XRF Disclaimer: Portable XRF readings are rapid, on-site estimates reflecting only a small portion of rock surface and are not necessarily representative of overall grades or assay results.

Notable Quotes

• "Having the drill start turning at Copper Creek marks an exciting milestone as we broaden our exploration footprint beyond our Star Main project area," stated Darryl Jones, chief executive officer of Star Copper. "The integration of modern geophysics, soil analysis and detailed mapping delivered clear targets for exploration. With the drill pads completed and the first of two planned [approximately] 400-metre holes under way, we are eager to test this structurally focused copper-gold system and report results as they become available."
