Super Copper Completes First Exploration Program at its Castilla Gold-Copper Project, Northern Chile

Executive Summary

• Super Copper Corp. completed its inaugural 2025 exploration program at the newly acquired Castilla Gold‑Copper Project in Chile’s Atacama Desert.
• The program involved systematic fieldwork on >15 historic occurrences, collection of 93 rock samples, and detailed geological mapping that identified quartz‑vein mineralization with copper, gold, iron‑oxide and sulphide minerals.
• Historical surface sampling (2023) returned up to 5.53 % Cu and 1.7 g/t Au, supporting the potential for a significant polymetallic IOCG system; full geochemical results are pending.

Key Details

• Program Scope: First‑pass prospecting focused on historic mineral occurrences, alteration mapping, and baseline geochemistry across the Castilla claim block.
• Fieldwork: Visits to more than 15 historic mineral occurrences distributed throughout the property.
• Rock Sampling: 93 rock samples collected from outcrops, historic mine workings, and surface veins showing visible copper‑bearing mineralization.
• Geological Observations:
• Quartz veins containing sulphides, copper‑bearing carbonates, and iron‑oxide (specular hematite, magnetite).
• Vein thickness ranging from a few centimetres to ~3 m within Cretaceous quartz diorite and tonalite intrusions.
• Historical Grades (2023 surface sampling): Up to 5.53 % Cu and 1.7 g/t Au from limited samples, indicating shallow‑level polymetallic potential.
• Structural Setting: Sub‑vertical veins trending N–S to NNW; historic underground workings extend >50 m depth, supporting an IOCG‑style model akin to other Chilean coastal belt deposits.
• Laboratory Analysis: All collected samples sent to ALS Laboratories (Chile); analytical results expected in the coming weeks.
• Next Steps:
• Incorporate field observations and mapping data into a new 3‑D geological model.
• Refine priority targets for follow‑up exploration, including potential drilling campaigns.
• Release full geochemical dataset and interpretive report once analysis and modeling are complete.
• Qualified Person (QP): Michael Dufresne, M.Sc., P.Geol., P.Geo., approved the scientific and technical information per NI 43‑101 standards.

Notable Quotes

“Castilla is a powerful addition to our copper‑gold pipeline. It sits in one of the most favorable geological belts in the Atacama and displays the structural and mineralogical features we like to see in early‑stage IOCG systems. This first program has already identified multiple zones of interest, and we're eager to review the analytical results and advance toward defining our next phase of work.” – Zachary Dolesky, CEO

Materiality Assessment: Non‑Material – Positive (early‑stage exploration update with promising historic grades but no definitive resource estimate).
