Star Copper releases early results at Star project

Executive Summary

• Preliminary results from drill holes S‑057 (completed) and S‑058 (in progress) tighten the 3‑D geometry of the Star Main system, extending the potassic‑chalcopyrite corridor westward and probing continuity northward.
• Hole S‑057 intersected quartz‑actinolite‑pyrite‑epidote veins with chalcopyrite at a scale of 0.5–1 cm, confirming sustained hypogene fluid flow and supporting the geological model.
• The company entered into a six‑month marketing and investor‑relations services agreement with Capital Analytica, paying $150,000 and issuing 200,000 incentive stock options (exercise price $1.20).

Key Details

• Hole S‑057 – Steep fan from the S‑056 pad (TD 511.25 m); intersected ~140 m of pervasive potassic alteration in quartz monzodiorite; chalcopyrite localized in quartz‑sulphide veins and vein halos; identified early quartz‑actinolite‑pyrite‑epidote veins with chalcopyrite (0.5–1 cm scale).
• Hole S‑058 – Vertically drilled step‑out 60 m north of historic hole S‑037; currently to ~250 m depth; passes oxidized fractured QMD → layered volcanic package with propylitic alteration and potassic halos; below ~130 m shows dense quartz‑pyrite‑chlorite‑magnetite (D‑type) veining with increasing chalcopyrite percentages.
• Sampling – Core from S‑057 has been sampled and sent to Bureau Veritas Laboratories for analysis under QA/QC protocols. Results pending release upon completion of S‑058 (target depth 500 m).
• Marketing Services Agreement – Effective Oct 5 2025, Capital Analytica will provide awareness, marketing, and IR services for six months; consideration: $150,000 cash + issuance of 200,000 incentive stock options at $1.20 exercise price, exercisable within 12 months.
• QA/QC – HQ‑ and NQ‑size diamond drilling; 5 % certified reference materials, blanks, and field duplicates inserted; analysis performed by ISO/IEC‑17025 accredited Bureau Veritas Laboratories using multielement ICP‑ES/MS and fire assay for precious metals.
• Qualified Person – Jeremy Hanson, P.Geo., independent contractor, reviewed and approved technical aspects of the release (NI 43‑101).

Notable Quotes

“Based on the results of our extremely promising six‑hole phase 1 drill program, our phase 2 campaign continues to build our understanding of the fault structure and grade of the supergene zone through and transition to hypogene copper mineralization at Star Main.” – Darryl Jones, CEO

Materiality Assessment: Non‑Material – Positive (early-stage drilling results that are encouraging but not yet indicative of a defined resource).
