Star Copper is trading 6.04% up at $0.58 after geological logging identified porphyry-style alteration and chalcopyrite mineralization beyond the historically defined footprint.
- On August 25, 2026, Star Copper announced it completed seven northeast step-out drill holes at Star Main.
- Assays remain pending for all seven holes; the program is anchored by a historic 269-metre copper-gold intercept.
- The drilling update appears to be the clear company-specific catalyst.
