SUPER COPPER COMPLETES FIRST EXPLORATION PROGRAM AT ITS CASTILLA GOLD-COPPER PROJECT, NORTHERN CHILE

Super Copper Corp. has completed its first exploration program at the recently acquired Castilla gold-copper project, located in Chile's Atacama Desert.

The Castilla project represents a new foundation for Super Copper, complementing its flagship Cordillera Cobre property with an emerging gold-copper system characterized by multiple historical workings, high-grade surface samples and strong geological signatures consistent with IOCG-style (iron oxide, copper and gold) mineralization.

Program highlights

The 2025 first-pass prospecting program focused on evaluating historical mineral occurrences, mapping alteration zones and collecting systematic samples to establish a modern geochemical baseline across the property.

Highlights include:

• Systematic fieldwork: Super Copper's technical team conducted site visits to more than 15 historical mineral occurrences distributed across the Castilla claim block.
• Rock sampling: A total of 93 rock samples were collected from outcrops, historical mine workings and surface veins, exhibiting visible copper and iron oxide mineralization.
• Geological observations: Mineralization was observed in quartz veins with sulphides, copper-bearing carbonates and iron oxide veins, containing specular hematite and magnetite. Vein thickness ranged from a few centimetres up to three metres, hosted primarily within Cretaceous quartz diorite and tonalite intrusions.
• Historical grades: Previous surface sampling from 2023 returned values of up to 5.53 per cent copper with 1.7 grams per tonne (g/t) gold from limited sampling, confirming the potential for significant polymetallic mineralization at shallow levels.

Geological context

The Castilla property hosts a network of subvertical veins trending north-south to north-northwest, with historical underground workings reaching depths of more than 50 metres. The combination of copper-gold mineralization, iron oxide alteration and structural control strongly supports an IOCG-style model, similar to deposits found throughout Chile's coastal range belt.

Zachary Dolesky, chief executive officer of Super Copper, stated: "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."

Next steps

All samples from the current program have been sent to ALS Laboratories in Chile for geochemical analysis, with results expected in the coming weeks. The company is also incorporating field observations and mapping data into a new 3-D geological model to refine priority targets for follow-up exploration and potential drilling.

Super Copper plans to release the complete geochemical results and geological interpretation once analysis and modelling are finalized.
