Super Copper Highlights Large-Scale IOCG-Style System at Castilla with Extensive Strike and Depth Continuity

Executive Summary

• Super Copper reports Phase 1 surface sampling and mapping at the 100% owned Castilla Copper‑Gold Project, indicating a large‑scale Iron Oxide Copper‑Gold (IOCG) system with extensive strike continuity (up to 500 m on site, 700 m district‑wide) and vertical continuity to ≥50 m depth.
• High‑grade surface samples returned up to 53.8 g/t Au, 17.7 % Cu, and >50 % Fe, supporting the presence of a high‑grade mineralized zone.
• The company will use these results to advance Phase 2 drilling, including property‑wide magnetics and IP surveys and 3D inversion modeling to refine target selection.

Key Details

• Geological Interpretation: Mapping and mineral assemblages are consistent with an IOCG system similar to world‑class copper‑gold deposits.
• Strike Continuity: Individual vein systems and historic mine workings mapped with strike lengths up to 500 m within Castilla; district‑wide veins reported up to 700 m, all open along strike under shallow cover.
• Vertical Continuity: Historical underground workings confirm mineralization to depths of at least 50 m; no modern drilling yet tested deeper extensions.
• High‑Grade Surface Results: Select surface samples recorded:
• Gold: up to 53.8 g/t Au
• Copper: up to 17.7 % Cu
• Iron: >50 % Fe (historical mining reported 60–66 % Fe in the massive iron oxide core).
• Vein Characteristics:
• Quartz‑gold‑copper veins 0.5–3.0 m wide, strike lengths 20–500 m, sub‑vertical dip.
• Massive iron‑oxide veins 1–3 m wide, 10–300 m strike length, dominated by hematite/magnetite with associated copper sulfides.
• Structural Setting: Project lies within the Atacama Fault System, a primary corridor for major copper‑gold mineralization in northern Chile.
• Next Exploration Steps:
• Property‑wide detailed sampling and mapping.
• Magnetics survey to delineate magnetite‑bearing zones; Induced Polarization (IP) survey to map sulfide concentrations.
• Integration of 3D magnetic inversions with IP chargeability/resistivity data for refined drill targeting.
• Finalize Phase 2 drill locations using Phase 1 results.
• QA/QC: Samples analyzed by ALS Group Chile and ALS Global (Peru) with fire‑assay/AAS for gold and 4‑acid digestion MS for copper; accredited laboratory with standards and blanks.
• Qualified Person Statement: Technical information approved by Michael Dufresne, M.Sc., P.Geol., P.Geo., independent QP under NI 43‑101.

Notable Quotes

“Our Phase 1 work confirms that Castilla is not a collection of isolated veins, but a structurally coherent and potentially large IOCG system,” – Zachary Dolesky, CEO, Super Copper Corp.

Materiality Assessment: Material – Positive (the release provides substantive new geological data indicating significant exploration potential and outlines concrete next‑step actions that could materially affect the company’s valuation).
