· 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
March 19, 2026 – Vancouver, British Columbia – 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:
o Northern Showing: 7.13% Cu with 98.7 g/t Ag (new discovery)
o Anima Mine Trend: 6.92% Cu over 1 m in chip samples
o 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.
