/CNW/ - Super Copper Corp. (CSE: CUPR) (OTCQB: CUPPF)
(FSE: N60) ("Super Copper" or the "Company") is pleased to report results from its phase one
geophysics program at the 100%-owned Castilla Project ("Castilla" or the "Project"). The integrated
datasets define property-scale alteration and structural corridors that are spatially coincident with
the high-grade gold and copper rock samples previously reported (see news release dated January
15, 2026), and have identified a new, previously unsampled iron-oxide gossan target in the northeast
portion of the Project (Figures 1 and 2).

Highlights
Property-scale alteration system mapped.
WV3 hyperspectral mapping defines a large,
coherent zone of phyllic (sericite) and propylitic (chlorite–epidote) alteration across central and
southwestern Castilla, spatially coincident with the Company's highest-grade surface samples.
Structural control confirmed.
Drone magnetic data (first vertical derivative of the reduced-to-
pole field, "1VD-RTP") define conjugate northwest- and northeast-trending structural corridors.
The highest-grade gold and copper rock samples cluster at the intersections of these structures
(Figure 1), the dilational settings that typically focus mineralization in Atacama iron-oxide-
copper-gold ("IOCG") systems.
Iron-oxide alteration over the interpreted IOCG core.
Mapped hematite alteration coincides
with the magnetite-rich, high-iron zone in north-central Castilla, including sample E02505 (17.7%
Cu, 39.1% Fe), consistent with an IOCG core.
New iron-oxide gossan target identified.
A large iron-oxide gossan and goethite footprint has
been mapped in northeastern Castilla, in an area not covered by the Company's 2025 rock-
sampling program. Gossans represent weathered, oxidized caps to sulphide bodies and are a
recognized vector to copper mineralization.
Alteration assemblage supports the IOCG model.
The near-absence of advanced argillic
alteration (no detectable alunite and only minor kaolinite) is consistent with an IOCG /
structurally-controlled system rather than a high-sulfidation epithermal system, helping to refine
the exploration model.
Depth-targeting datasets to follow.
Total-field magnetic products, a three-dimensional
magnetization vector inversion ("MVI"), and an induced polarization ("IP") survey are planned to
model magnetite (IOCG) bodies and sulphide mineralization at depth, and to rank drill-ready
targets for a maiden diamond drill program at Castilla.

rock-sample copper grades overlaid, including the 17.7% Cu IOCG-core sample (E02505) in north-
central Castilla. The northeastern gossan target again stands out in warm colours, in ground not
covered by the 2025 sampling program. (CNW Group/Super Copper Corp.)
Geophysical and Alteration Survey
The drone magnetic survey was completed at Castilla over the Company's claim package, with
magnetic data processing, structural interpretation and three-dimensional modelling performed by
APEX Geoscience Ltd. ("APEX"). The first vertical derivative of the reduced-to-pole field ("1VD-
RTP") sharpens near-surface magnetic edges and reveals the Project's structural backbone: a
dominant northwest–southeast trend, consistent with the regional Atacama structural grain, cut by a
northeast–east-northeast set of cross-structures. Where those two directions cross is exactly where
the highest-grade samples sit.
The WV3 alteration mapping was completed by PhotoSat Information Ltd. ("PhotoSat") using
WorldView-3 satellite imagery and PhotoSat's deep-learning mineral-mapping process, delivered to
the Company on June 11, 2026. The survey mapped twelve alteration mineral products at 2-metre
resolution. Key results:
Sericite (phyllic) alteration:
Widespread and intense across the central and southwestern
Project area, hosting the Company's central gold corridor and southwestern copper
occurrences.
Chlorite-epidote (propylitic) alteration:
Extensive across the southwestern and central
Project area, forming a broad peripheral halo.
Hematite and iron-oxide alteration:
Concentrated in north-central Castilla, coincident with the
interpreted magnetite-rich IOCG core and historical iron-oxide workings.
Iron-oxide gossans and goethite:
A large footprint in northeastern Castilla, in ground not
previously sampled by the Company, interpreted as a new target.
Together, the structural and alteration datasets indicate that the high-grade surface mineralization at
Castilla sits within a large, coherent hydrothermal alteration system controlled by intersecting
structures, a setting consistent with IOCG-style deposits of the Chilean Copper Belt.
Management Commentary
"Castilla is coming together fast," said
Zachary Dolesky, CEO of Super Copper.
"We already
knew the surface grades were excellent with up to 53.8 g/t gold and 17.7% copper. This new
dataset adds scale and control. We can now see that our best hits sit at the intersection of
structure, alteration and geochemistry, inside a property-scale hydrothermal system. The alteration
assemblage points at an IOCG model, and on top of that we've identified an entirely new gossan
target in the northeast that we've never sampled. The upcoming 3D magnetic inversion and IP survey
will let us image potential sulphides at depth and push the strongest targets towards a prospective
drilling program."
Next Steps
The Company is advancing the following work programs at Castilla:
1
.
Total-field magnetic products and 3D MVI inversion.
APEX will deliver the total magnetic
intensity (reduced-to-pole) imagery and a three-dimensional MVI model to image magnetite-
bearing bodies at depth and resolve magnetite-additive (IOCG core) versus magnetite-
destructive (alteration) domains. The MVI methodology solves for magnetization direction and is
suited to settings where remanent magnetization is present.
2
.
Induced polarization survey.
An IP survey is planned to map chargeability associated with
sulphide mineralization below the depth of effective surface sampling. Survey design will be
finalized following review of the magnetic and alteration datasets.
3
.
Target ranking and drill planning.
All datasets: surface geochemistry, structure, alteration,
3D magnetics and IP, will be integrated under the supervision of the Company's Qualified
Person to prioritize and rank targets for a prospective
maiden drill program at Castilla.
These programs at Castilla advance in parallel with the Company's maiden diamond drill program at
its Cordillera Cobre Project, where drilling of geophysically-defined IOCG targets is expected to
start soon.
