Super Copper completes exploration program at Castilla

Executive Summary

• Super Copper Corp. completed its first exploration program at the Castilla gold-copper project in Chile's Atacama Desert, marking a significant step in the evaluation of this newly acquired asset.
• The program focused on prospecting, mapping, and sampling across 15 historical mineral occurrences, identifying geological features consistent with IOCG-style mineralization.
• Historical surface sampling from 2023 previously returned high-grade results (up to 5.53% Cu and 1.7 g/t Au), and current samples have been sent for analysis to define next-phase exploration targets.

Key Details

• Project Location: Castilla gold-copper project, Atacama Desert, Northern Chile.
• Program Scope: First-pass prospecting program involving site visits to more than 15 historical mineral occurrences across the claim block.
• Sampling Data:
  • 93 rock samples collected from outcrops, historical mine workings, and surface veins.
  • Samples exhibited visible copper and iron oxide mineralization.
• Geological Findings:
  • Mineralization observed in quartz veins with sulphides, copper-bearing carbonates, and iron oxide veins containing specular hematite and magnetite.
  • Vein thickness ranges from a few centimeters up to three meters.
  • Host rock primarily consists of Cretaceous quartz diorite and tonalite intrusions.
  • Subvertical veins trend north-south to north-northwest; historical underground workings reached depths of over 50 meters.
• Historical Grades: Previous 2023 surface sampling returned values of up to 5.53% copper and 1.7 grams per tonne (g/t) gold.
• Mineralization Style: IOCG-style (iron oxide, copper, and gold) mineralization, similar to deposits in Chile's coastal range belt.
• Next Steps:
  • Samples sent to ALS Laboratories in Chile for geochemical analysis.
  • Results expected in the coming weeks.
  • Development of a new 3-D geological model to refine priority targets for follow-up exploration and potential drilling.
• Qualified Person: Michael Dufresne, MSc, PGeol, PGeo.

Notable Quotes

• "Castilla is a powerful addition to our copper-gold pipeline. It sits in one of the most favourable 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, Chief Executive Officer
