Super Copper identifies gold mineralization at Castilla

Executive Summary

• Super Copper Corp. reports assay results of up to 5.0 g/t gold and 5.5 % copper from initial rock sampling at the Castilla project in northern Chile.
• The discovery confirms spatial association of gold with quartz‑carbonate veins and copper‑bearing iron oxide systems, expanding the project's precious‑metal potential.
• Approximately 93 rock samples have been collected; a further ~100 samples are already submitted for analysis to delineate the extent of the gold‑bearing system.

Key Details

• Assay Highlights:
• Highest reported grade: 5.0 g/t Au and 5.5 % Cu from historical workings/outcrops sampled in late 2023.
• Sampling Program:
• Initial phase involved 93 rock chip samples from priority target zones across the 7,200‑ha Castilla concession (25 exploration permits).
• An additional ≈100 samples have been submitted to ALS Global Laboratories (Santiago) for assay; results expected in coming weeks.
• Geological Context:
• Gold mineralization occurs within at least two generations of quartz‑plus‑carbonate veins that intersect the copper‑bearing iron oxide system.
• Vein systems are hosted by altered diorite intrusives and are associated with magnetite‑bearing structures trending N‑S to NW.
• Project Scope:
• Castilla covers ~7,200 ha across 25 concessions, featuring surface oxidation zones, magnetite veining, visible copper mineralization, and structural corridors.
• Quality Assurance/Control:
• Samples analyzed at ALS Global Laboratories (ISO/IEC 17025:2017 accredited).
• Duplicates, blanks, and reference standards used; chain‑of‑custody procedures maintained.
• Qualified Person: Michael Dufresne, MSc, PGeol, PGeo – independent QP under NI 43‑101.

Notable Quotes

“These early gold values are a significant addition to our exploration opportunity at Castilla. They confirm that our system carries both copper and precious metal potential, a key characteristic of some of Chile's most productive deposits.” – Zachary Dolesky, CEO, Super Copper Corp.
