Super Copper Announces Up to 5.0 g/t Gold Mineralization at the Castilla Project

Executive Summary

• Super Copper reports historic rock‑grab samples from the Castilla Project yielding up to 5.0 g/t Au and up to 5.5 % Cu, confirming gold presence within quartz‑carbonate veins associated with copper mineralization.
• A total of 93 new surface rock samples have been collected in 2025; assay results are pending and will be used to refine a Phase I drill targeting model.
• The company is expanding its systematic surface sampling program (≈100 samples) and integrating detailed mapping, geochemistry, and ground magnetic surveys to define the gold‑copper relationship across multiple target zones.

Key Details

• Assay Highlights:
• Historical grab samples (late 2023) returned 5.0 g/t Au and 5.5 % Cu.
• Sampling Program:
• 93 rock chip samples collected in 2025 from priority zones; results expected “in the coming weeks.”
• Near‑100 total samples now submitted for laboratory analysis.
• Geological Context:
• Gold mineralization occurs within at least two generations of quartz‑carbonate veins and copper‑bearing iron‑oxide systems.
• Veins are hosted by altered diorite intrusives with magnetite‑bearing structures, trending N‑S to NW.
• Project Scope:
• Castilla Project covers ~7,200 ha across 25 exploration concessions in northern Chile.
• Future Work Plan:
• Ongoing detailed surface mapping, systematic sampling, and ground magnetic surveys.
• Data will feed into a Phase I drill targeting model to test the gold‑copper relationship.
• Quality Assurance/Control:
• Samples analyzed by ALS Global Laboratories (ISO/IEC 17025:2017 accredited).
• Duplicates, blanks, and SRMs used; chain of custody maintained.
• Qualified Person Statement:
• Technical information reviewed and approved by Michael Dufresne, M.Sc., P.Geol., P.Geo., 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

Materiality Assessment: Material – Positive (the discovery of economically significant gold grades alongside copper at a large, multi‑concession project represents a materially positive development for the company’s valuation and future drilling plans.)
