Super Copper Corp. (CSE: CUPR) has announced results from new three-dimensional modelling of magnetic survey data at its Castilla Project in Chile's Atacama Region, identifying multiple kilometre-scale magnetic target zones beneath high-grade surface copper and gold samples. The modelling, carried out by APEX Geoscience Ltd., supports the company's interpretation that Castilla may host a structurally controlled iron oxide copper-gold (IOCG) system — the deposit style behind several of Chile's large copper-gold mines. Investors may be watching closely given the scale of anomalies identified and the company's outlined follow-up programme.

Key Points

  • Super Copper Corp. (CSE: CUPR | OTCQB: CUPPF | FSE: N60)
  • 3D magnetic vector inversion modelling at the Castilla Project identifies multiple kilometre-scale subsurface magnetic anomalies interpreted to begin at or near surface
  • Principal anomalies extend to approximately 400–800 metres depth; certain responses reach the approximately 2,500-metre base of the inversion model; surface samples graded up to 17.7% copper and 53.8 g/t gold
  • Investors should watch for results of a planned induced polarization survey designed to define drill targets above the buried magnetic bodies

What the 3D Magnetic Modelling Revealed at Castilla

APEX Geoscience Ltd. processed data from a drone magnetic survey flown by Geodatos at 50-metre line spacing over an 8 km by 9 km area, using magnetic vector inversion (MVI) to build a three-dimensional picture of subsurface magnetism. The technique can detect magnetite that crystallised in ancient mineralising systems and retained a fossil magnetic direction. The resulting model shows several steep-sided, tabular magnetic bodies in close proximity to gold-bearing surface anomalies, while the magnetic response at surface remains quiet — a pattern the company states is consistent with the hematite-rich upper levels of an IOCG system, where copper-gold mineralisation typically forms.

High-Grade Surface Copper and Gold Clustering Above Buried Anomalies

Rock grab samples collected during the company's 2023 and 2025 field programmes returned gold values up to 53.8 g/t and copper values up to 17.7%, with 22 of 95 samples grading above 1.0 g/t gold. The release states that samples with higher gold, copper, and iron grades cluster directly above and along the edges of the buried magnetic bodies. Samples were prepared and analysed by ALS Global Laboratories, an independent ISO/IEC 17025-accredited facility. The company cautions that rock grab samples are selective by nature and are unlikely to represent average grades across the project.

Planned Induced Polarization Survey to Define Drill Targets

Super Copper's announced next step is an induced polarization (IP) survey over areas where surface copper and gold anomalies sit above buried magnetic anomalies. The survey is designed to detect high chargeability associated with sulphide minerals related to copper and gold. In parallel, the company states it will continue geological mapping, measure rock magnetic susceptibility to refine the 3D model, interpret fault structures, and integrate WorldView-3 satellite alteration data completed by PhotoSat. The disclosed goal is a ranked list of drill targets where sulphide response, structure, and surface copper coincide.
