Star Copper Completes Copperline Field Program with Drill Permit Submitted for 2026

Executive Summary

• Star Copper completed its inaugural reconnaissance field program on the 945‑ha Copperline Property, confirming historic copper‑silver mineralization with visible malachite at the Beaman Adit and mineralized float below the Main Zone.
• Infill soil sampling was conducted to extend 2023 copper‑in‑soil anomalies (up to 463 ppm Cu); assay results are pending.
• Historic drill core was located on‑site for future re‑logging and verification, supporting the volcanic redbed copper‑silver deposit model.

Key Details

• Property Overview: 8 claims (~4,502 ha) in north‑central BC; 945 ha actively explored; access by helicopter or logging roads.
• Field Program Date: October 30 2025 (snow‑covered conditions, crews on snowshoes).
• Visible Mineralization: Four rock grab samples from historic Beaman Adit showed malachite staining, confirming copper presence.
• Float Observation: Malachite‑bearing boulders collected below the Main Zone, interpreted as talus derived from upslope mineralization.
• Soil Sampling: Infill lines (four east‑west traverses) sampled at 25 m spacing to test extensions of 2023 anomalies (449–463 ppm Cu). Results pending.
• Historic Drill Intercepts (1973‑74):
• DR‑9 – 25 m @ 2.54 % Cu, 50.4 g/t Ag
• DR‑11 – 9.1 m @ 2.94 % Cu, 83.3 g/t Ag
• DR‑12 – 3.0 m @ 3.05 % Cu, 78.9 g/t Ag
• DR‑1 – 12.2 m @ 1.62 % Cu, 35.0 g/t Ag
• Historic Core: Cross‑stacked drill core located at 649970 E / 6190360 N; available for future examination and re‑sampling.
• Future Priorities Identified:
• IP geophysical survey (never completed).
• West Zone (MINFILE 093M230) – historic 2.14 % Cu, 50.2 g/t Ag, untested by drilling.
• Dave’s Zone (MINFILE 093M231) – outcrop, untested.
• Strike extensions north of DR‑2 and south of DR‑12; down‑dip potential beyond historic ~150 m depth.
• QA/QC: Samples processed at Bureau Veritas Laboratories under chain‑of‑custody; QA/QC program includes ≥5 % certified reference materials, blanks, and duplicates.
