Super Copper Announces Bonanza-Grade Gold Discovery at Castilla: Assays up to 53.8 g/t Gold and 17.7% Copper

January 15, 2026 – Vancouver, British Columbia

SUPER COPPER CORP. (CSE: CUPR) (OTCQB: CUPPF) (FSE: N60) (“Super Copper” or the “Company”), is pleased to announce a high-grade discovery from rock grab samples following the completion of its Phase 1 surface sampling program at the 100%-owned Castilla Copper-Gold Project, located in the prolific Atacama Region of Chile.

• Bonanza Gold Discovery: Surface sampling headlined by exceptional grades of 53.8 g/t Au, among the highest reported in the Atacama region this year.
• Exceptional Copper Grades: Results include up to 7% Cu, confirming the potential for a high-grade sulfide system.
• Significant Iron Values: 10 assays exceeding0% Fe, 23 assays exceeding 10.0% Fe, levels typically observed in IOCG systems.
• Strong Grade Distribution: 25% of all assays returned grades, demonstrating property-scale mineralization rather than isolated anomalies.

The sampling program, which is comprised of mostly selective rock grab samples and floats, has identified a high-grade, multi-commodity mineral system characterized by bonanza-grade gold (Au), exceptionally high copper (Cu) and iron (Fe) values, supporting the presence of a large and robust mineralizing system. Although the sampling was mostly selective rock grab and float samples, and by nature represent a biased high population, the presence of a robust mineralization system is supported by the fact that there are numerous samples from numerous locations that have yielded greater than 1 gram per tonne (g/t) Au and 1 percent (%) Cu along with significant alteration and pathfinder elements as shown in Tables 1 to 3, and on Figures 1 to 5.

“These results represent a defining discovery moment for Super Copper,” said Zachary Dolesky, CEO. “Grades of 53.8 g/t gold, 17.7% copper, and over 50.0% iron are exceptional on their own, but what matters most is the consistency and scale emerging across the property. The combination of gold, copper, iron and pathfinder elements points to a robust mineralizing system rather than a single isolated occurrence. With multiple mineralized structures identified, Castilla is quickly shaping up as a potential flagship asset in one of the world’s premier copper-gold jurisdictions.”

Discovery Highlights:

High-Grade Hit Rate:

• 24 of 93 samples (25%) returned gold grades over 1.0 g/t Au.
• 8 of 93 samples returned copper grades over 1.0% Cu, and 24 samples returned higher than 0.1% Cu.
• 10 of 93 samples returned iron grades over 50.0% Fe, and 23 samples returned iron grades over 10.0% Fe.

Bonanza Gold:

• 53.8 g/t Au (Sample E02610). Quartz vein float from historical mine working.
• 15.9 g/t Au (Sample E02567). Quartz vein float from historical trench.
• 6.09 g/t Au (Sample E02521). Sheared/brecciated vein in old near vertical shaft.

Exceptional Copper:

• 17.7% Cu (Sample E02505). Float near excavation of magnetite vein breccia with malachite and minor chrysocolla and azurite. Malachite infilling fractures and in breccia cement.
• 6.86% Cu (Sample E02525). Float near old mine working. Altered quartz diorite.
• 3.27% Cu (Sample E02506). Quartz vein hosted in quartz diorite with malachite and chalcocite.

High Grade Iron Oxide Veins:

• 10 of 93 samples returned iron grades over 50.0% Fe, hosted in magnetite-, hematite-, and specular hematite–rich veins and brecciated zones with quartz and minor copper sulphides within diorite.

Strategic Location:

• Situated in Chile’s Atacama Region, host to multiple world-class copper-gold deposits and established infrastructure.

The Castilla Project is located within a world-class copper-gold belt. Notably, the lack of direct correlation between peak gold and peak copper values suggests the presence of multiple mineralized structures, rather than a single localized zone, an important indicator of scale. Mineralization is consistent with IOCG style deposits typically reported in the region with possible superimposed events associated with gold bearing quartz veins. Extent and depth of these veins remain to be determined.

Upcoming Exploration & Catalysts

Building on these results, Super Copper is accelerating exploration activities at Castilla:

• Further property wide detailed sampling and mapping.
• Property-Wide Magnetics and IP Survey: Magnetics to map magnetite bearing zones such as iron oxide copper-gold (IOCG) veins, breccia zones and related skarns; Induced Polarization geophysics to map sulfide concentrations and identify high-priority targets at depth.
• Advanced Targeting: Integration of 3D magnetic inversions along with inversions of IP chargeability and resistivity data to refine drill targeting and structural interpretation.
• Drill Planning: Results will be used to finalize Phase 2 drill locations.

QA/QC

All samples were submitted to ALS Group Chile with a preparation laboratory in Copiapo. Analysis was carried out at ALS Global laboratories in Peru. Gold was determined by Fire Assay with an AAS finish and Gravimetric finish for over-limits. Copper was analyzed via 4-acid digestion ME-MS61 with Cu-OG62 for overlimits. ALS is an accredited geoanalytical laboratory with rigorous QA/QC program with the use of standards and blanks.
