• Mineralized clusters occur across approximately 8 km of strike, supporting the interpretation of a large structurally controlled copper system at Cordillera Cobre.
• New high-grade copper (Cu) discovery in previously undrilled northern project area returning up to 7.13% Cu and 98.7 grams per tonne (g/t) silver (Ag) from outcrop samples
• Three distinct high-grade target areas confirmed at surface: Northern Showing 7.13% Cu, Anima Mine Trend 6.92% Cu/1 meter (m), Calcite Hill 3.40% Cu/1m
• El Alto Trench: 17m @ 0.34% Cu including 2m @ 1.48% Cu, confirming continuity and width potential below surface, consistent with a structurally controlled deposit at depth
• Ground magnetometry (800+ ha) defines NW-trending structural corridors; IP survey now complete, chargeability results to be released in the near future

VANCOUVER, BC, March 19, 2026 /CNW/ - SUPER COPPER CORP. (CSE: CUPR) (OTCQB: CUPPF) (FSE: N60) ("Super Copper" or the "Company") is pleased to report Phase 1 exploration results from its flagship Cordillera Cobre Project, located in Chile's Atacama region. Cordillera Cobre is one of two copper exploration assets held by the Company in the Atacama belt, alongside the Castilla Project, which Super Copper acquired in 2025 and is advancing through early-stage exploration.

Phase 1 represents its most significant field program to date: two new high-grade copper zones discovered in a completely undrilled area, with excellent surface grades confirmed across three distinct target areas, and structural controls on mineralization mapped across 800+ hectares via ground magnetometry. The IP survey is now complete, with chargeability data being processed for near term release.

Highlights

• Two new high-grade copper zones discovered in the northern project area, returning up to 7.13% Cu and 4.78% Cu from rock grab samples of outcrop, in an area with no prior drill testing
• 24 of 102 rock grab samples exceeded 1% copper, with 10 samples returning greater than 3% Cu, demonstrating widespread high-grade mineralization across multiple target areas
• Excellent surface grades confirmed at three distinct target areas:
  • Northern Showing: 7.13% Cu with 98.7 g/t Ag (new discovery)
  • Anima Mine Trend: 6.92% Cu over 1 m in chip samples
  • Calcite Hill: 3.40% Cu over 1 m in chip samples
• El Alto Historical Trench T-267A returned 17 m grading 0.34% Cu, including 2 m at 1.48% Cu in chip samples, demonstrating continuity and width potential, and potentially indicative of a structurally controlled system at depth
• An IP survey is now complete across El Alto and Calcite Hill target areas; chargeability results to be released imminently 

Why These Results Matter

Super Copper's Phase 1 results at Cordillera Cobre include samples grading up to 7.13% Cu across multiple target areas, well above typical mine grades in the region.

The combination of high-grade copper exposed at surface, multiple mineralized zones, and structural controls now defined by geophysics de-risks the path to targets and provides a technical foundation for high-confidence drill target selection. These combined results indicate the potential for a larger, structurally controlled copper system rather than isolated high-grade occurrences.

New High-Grade Results in the North

Phase 1 prospecting identified two previously unknown high-grade copper zones in the northern portion of Cordillera Cobre, an area not covered by historical drilling. The newly designated Northern Showing returned 7.13% Cu with 98.7 g/t Ag and 4.78% Cu in rock grab samples from outcrop. Mineralization is hosted in breccias and veins within diorite (northernmost cluster) and volcaniclastic rocks, and appears structurally controlled, with the two zones located approximately 1.5 kilometres apart (Figure 1).

The 1.5-kilometre separation between the two zones, combined with consistent structural orientation, suggests these are not isolated occurrences but surface expressions of a broader mineralized system, one that has received no drill testing to date. The Northern Showing is now a priority target for follow-up work alongside El Alto and Calcite Hill.

Phase 1 Assay Results Summary

The program resulted in the collection of 102 rock samples from outcrops, trenches, and underground workings. Results are summarized below in tables 1 and 2, sorted by grade:

Geophysics: Defining the Drill Targets

Ground magnetometry across 800+ hectares reveals a coherent set of northwest-trending structural corridors controlling mineralization at both Calcite Hill and El Alto. Magnetic low anomalies, reflecting magnetite destruction by hydrothermal fluids, a hallmark of Atacama copper systems, are spatially coincident with the project's highest-grade surface samples (see Figure 2, Insets A and B).

The magnetometry data has now been integrated with an Induced Polarization (IP) survey across both the El Alto and Calcite Hill target areas. IP chargeability results will be released in a subsequent announcement. While magnetics define where the hydrothermal system was active, IP chargeability pinpoints potential disseminated sulphide concentrations at depth, which will help convert structural targets into high-confidence drillable targets. The full dataset will advance the Company toward its Phase 1 drill program, targeted for Q2 2026.

Zachary Dolesky, CEO of Super Copper, stated: "What Phase 1 has given us is a fundamentally different company than six months ago. What began as a single historic target has evolved into multiple high-priority copper zones across a large structurally controlled system. With high-grade copper now confirmed at surface and geophysics defining drill targets, we are moving toward our first drill program with the strongest target pipeline in the Company's history."

Technical Analysis

The Phase 1 campaign marks the Company's most comprehensive field program to date at Cordillera Cobre, designed to validate historical drill results and generate new data across multiple high-priority copper zones to support drill target definition.

All rock samples were submitted to ALS Laboratories in Chile for geochemical analysis. The geophysical survey was carried out by Argali Geophysics. These results form the foundation for Super Copper's next phase of target definition, with Phase 1 drilling targeted for Q2 2026.
