Super Copper Commences Property-Wide Geophysics at Castilla Copper-Gold Project, Atacama, Chile
Integrated drone magnetics, induced polarization (IP) and WorldView-3 hyperspectral programs designed to convert surface signatures (up to 53.8 g/t Au and 17.7% Cu) into drill-ready targets
VANCOUVER, BC, May 26, 2026 /CNW/ - Super Copper Corp. (CSE: CUPR) (OTCQB: CUPPF) (FSE: N60) ("Super Copper" or the "Company") is pleased to announce that it has commenced an integrated geophysical and hyperspectral exploration program at its 100%-owned Castilla copper-gold project ("Castilla" or the "Project"), located approximately 60 km southwest of Copiapó in Chile's Atacama region. The program is designed to systematically convert Castilla's extensive surface mineralization, including results of up to 53.8 g/t Au and 17.7% Cu, into ranked, drill-ready targets across the property.
Program Highlights
- Drone-borne magnetic survey engaged to complete high-resolution total-field magnetics over the full property footprint, flown at 50 m above ground level using a Geometrics MagArrow cesium-vapour magnetometer on a DJI Matrice 300 RTK platform
- WorldView-3 satellite hyperspectral imagery engaged with PhotoSat Information Ltd. for high-resolution alteration mineral mapping over an 85 km² core area, complemented by a regional (R-HET) hyperspectral package covering 2,000 km²
- Induced Polarization (IP) survey to follow on highest-priority targets identified by magnetics and hyperspectral integration, designed to map disseminated sulphides and chargeable bodies at depth
- Integrated 3D inversion of magnetic and IP datasets planned to deliver a fully-modelled targeting package
CEO Commentary
"Castilla has already produced some of the most striking surface signatures in our portfolio, 53.8 g/t gold and 17.7% copper from grab samples, and consistent IOCG-style iron values across the property," said Zachary Dolesky, Founder and CEO of Super Copper. "What the project has not had is the modern geophysical coverage needed to vector those signatures into the subsurface. This program changes that. Drone magnetics will map the structural architecture and IOCG plumbing system, WorldView-3 will fingerprint the alteration footprint at two-metre resolution, and IP will test the highest-priority chargeable targets at depth. Our objective is simple: develop a maiden Castilla drill program with a ranked, geophysically-defined target inventory."
Castilla Project Background
The Castilla project comprises a ~7,200 hectare 100%-owned land package in Chile's Atacama region, with no underlying royalties or back-in rights. Surface sampling has returned high-grade results including up to 53.8 grams per tonne (g/t) gold (Au) and 17.7% copper (Cu) from selective grab samples, with mineralized vein systems mapped over strike lengths of up to 500 metres. Significant iron values, 23 assays returning greater than 10% Fe and 10 assays greater than 50% Fe, are consistent with an Iron Oxide Copper-Gold (IOCG) style system. Historical artisanal underground workings confirm continuity of mineralization to at least 50 metres depth; the property has never been drill-tested.
Castilla is positioned along the Atacama Fault System (AFS), the same regional structural corridor that hosts producing and historic mines including Manto Negro and Osornina. The current program is designed to integrate magnetic, IP, and hyperspectral datasets into a single 3D targeting framework, building on the Company's technical approach previously applied at the El Alto target on the Cordillera Cobre project.
Drone Magnetic Survey
The Company has engaged a Santiago-based geophysical services contractor with ISO 9001, 14001 and OHSAS 18001 accreditation, to execute a property-wide drone-borne magnetic survey at Castilla. Key survey parameters:
- Platform: DJI Matrice 300 RTK drone with Geometrics MagArrow total-field cesium-vapour magnetometer
- Base station: Geometrics G-859 for diurnal correction and magnetic storm monitoring
- Flight height: 50 metres above ground level, terrain-following using SRTM digital elevation model
- Line spacing: production lines spaced every 100 metres east-west, with north-south tie lines every 1,000 metres
- Total survey: approximately 798 line-kilometres across the property
- Deliverables: total magnetic intensity (TMI), reduced-to-pole (RTP), first vertical derivative, and analytic signal maps, with optional 3D magnetic susceptibility inversion using the UBC MAG3D system
Field acquisition is expected to take approximately eight days, followed by processing and reporting.
WorldView-3 Hyperspectral Imagery: PhotoSat
In parallel, the Company has engaged PhotoSat Information Ltd. of Vancouver to deliver an integrated remote-sensing alteration mapping package including WorldView-3 high-resolution satellite imagery and hyperspectral dataset:
- WorldView-3 alteration mapping will be carried out over an 85 km² core area at the Castilla property, mapping up to 12 alteration minerals (including kaolinite, alunite, sericite, chlorite/epidote, calcite, hematite, goethite, jarosite, and iron-oxide gossans) at 2-metre resolution
- Context imagery including geology-enhanced colour, SWIR-enhanced, Sabins composite and Sultan composite images for structural and lithological interpretation
The combined hyperspectral package is designed to characterize the surface alteration footprint of the Castilla IOCG system, identify previously unmapped alteration centres, and provide an independent dataset that can be co-registered with magnetic anomalies to high-grade IP target selection.
Induced Polarization (IP) Survey
Following completion and integration of the magnetic and hyperspectral datasets, the Company anticipates deploying a ground IP / resistivity survey across the highest-priority target areas. The IP program will be intended to detect disseminated sulphide mineralization and chargeable bodies at depth, replicating the targeting workflow previously applied by the Company at the El Alto target on the Cordillera Cobre project, where IP, magnetics and MVI inversion defined an 800-metre coincident anomaly corridor now being advanced to maiden diamond drilling.
Final IP line layout, total line-kilometres and contractor selection will be confirmed and announced following review of the magnetic and hyperspectral results.
Next Steps
- Drone magnetic acquisition: mobilization within approximately two weeks of contractor preparation period
- PhotoSat hyperspectral deliverables: digital deliverables expected in parallel with magnetic acquisition
- Integrated magnetic and hyperspectral targeting review and announcement of IP survey design
- 3D inversion and final target ranking
