CopperCorp Confirms Large Untested EM Anomaly
Beneath Historical Cu-Au Mine at Jasper Hills, Tasmania
VANCOUVER, BC June 16th, 2025 – CopperCorp Resources Inc. (TSXV: CPER) (OTC QB: CPCPF)
(“CopperCorp” or the “Company”) is pleased to announce that reviews of historical data has identified a
large electromagnetic (EM) conductor drill-target beneath historical copper mine workings at the Jasper
Hills prospect, part of the Company’s 100%-owned AMC Project in western Tasmania, Australia.
The conductor was confirmed through advanced reprocessing and modelling of historical airborne
Versatile Time-Domain Electromagnetic (VTEM) data, integrated with legacy downhole EM surveys. The
results provide compelling evidence of a southwest -dipping bedrock conductor located down -dip of
previously reported high -grade copper-gold mineralization sampled at the Old Jasper historical mine
workings1.
HIGHLIGHTS
• Modelled VTEM anomaly defines a 1km long southwest-dipping bedrock conductor extending
beneath the historical Old Jasper copper mine workings at Jasper Hills.
• Anomaly is consistent with interpreted down-dip extension of previously reported anomalous Cu-
Au in rock chip sampling (with up to 16.45% Cu and 10.1g/t Au)1 taken at surface over the area of
historical workings, indicating a strong vector for potential massive sulphide style mineralization.
• Reprocessed geophysical data indicates that historical drilling did not intersect the main
conductor horizon.
• Target is drill-ready with a fully permitted drill program in place.
• Jasper Hills is 100% owned by CPER and is favourably located within excellent access to mining
infrastructure.
• Western Tasmania is renowned for hosting large-scale VMS deposits, including Roseberry (52Mt
@ 13% Zn, 4% Pb, 0.5% Cu, 1.9g/t Au and 132g/t Ag)4, which has been in operation since 1936.
Stephen Swatton, President and CEO of CopperCorp commented:
“Jasper Hills has been a prospect that we have been quietly working on for the past 3 years and while we
consistently sampled high grade copper outcrop and mine ‘muck pile waste’ we struggled to find targets
that were sizeable enough to warrant drilling. CopperCorp’s recent geophysical re-interpretation has now
confirmed a large undrilled geophysical EM conductor. The project is easily accessible by road and credit
to the geological team that through persistence and astute application of recent reprocessing and
interpretive techniques to old data have provided evidence for a compelling sizable drill target. I will be
excited to see a drill turning at this site in the near future.

The reinterpretation of historical geophysical data with modern techniques and algorithms combined with
our own rigorous geological and geochemical ground-truthing at both historical mineral showings / mine
sites and new locations has been the basis for most of the Company’s recent target generation. In the past
2-5 years t he advance s in th e quality of the geophysical and geochemical interpretation have been
considerable and our projects are particularly suitable for this type of review because of the large amount
of publicly available data in western Tasmania that stretches back over 120 years.”
JASPER HILLS - BACKGROUND
The Jasper Hills prospect is located within Exploration License EL1/2020, situated approximately 10km
east of the operat ing Savage River magnetite mine and approximately 35km northeast of CopperCorp’s
Alpine prospect (Figure 1). The prospect area includes a cluster of historical open pit and underground
copper workings developed on near-surface high-grade copper-gold lodes at the Old and New Jasper
mines during the early 1900’s.
Copper-gold mineralization at Jasper Hills occurs as vein and disseminated to blebby chalcopyrite with
secondary bornite, covellite, chalcocite and malachite ( Figures 4). The high-grade copper mineralization
is hosted in variably silica-altered basalt, pyroxenite and sedimentary rocks and is currently interpreted to
be related to a possible VMS style primary volcanogenic system (Cambrian age), with possible later
remobilization and upgrading in structurally hosted positions during Devonian age granite intrusion
events.
As previously reported 1, reconnaissance rock chip sampling by CopperCorp in 2023 confirmed highly
anomalous copper and gold grades at Jasper Hills with best assays including 16.5% Cu with 0.23g/t Au
and 133g/t Ag, 14.4% Cu with 1.34g/t Au and 129g/t Ag , 3.12% Cu with 2.08g/t Au and 40g/t Ag , and
1.67% Cu with 10.1g/t Au . For further background information, please refer to the Company’s TSX-V
announcement dated April 26th, 20231.
The extensively mineralized Cambrian volcanic terranes of western Tasmania host several world-class
VMS deposits, including the Rosebery (52Mt @ 13% Zn, 4% Pb, 0.5% Cu, 1.9g/t Au and 132g/t Ag) 4 and
Hellyer (16.9Mt @ 13.8% Zn, 7.2% Pb, 0.4% Cu, 2.5g/t Au and 167g/t Au) 5 deposits, demonstrating a
proven geological setting favorable for such mineralization. The area's complex tectonic and volcanic
history has created multiple horizons with potential for undiscovered mineral systems, especially in the
Mount Read Volcanics and other underexplored adjacent volcanic terranes such as that hosting Jasper
Hills. Advances in geophysical techniques and modern exploration models also enhance the potential for
new discoveries, making western Tasmania an attractive target for continued VMS exploration.
GEOPHYSICAL REPROCESSING AND INTERPRETATION
The EM conductor at Jasper Hills was confirmed through a comprehensive re -evaluation of geophysical
data from 2008 airborne VTEM and 2013 downhole EM (DHEM) surveys carried out at the prospect by
previous explorers.
CopperCorp engaged specialized consultants to undertake reprocessing and re-modelling of the historical
data using modern algorithms and improved conductivity modelling techniques. Extensive imaging of the
VTEM EM Z component dB/dt decay time channel data were completed, as well as CDI 1D modelling of
the VTEM survey data along flight lines and gridded into 3D models . A suite of data products was
generated from the model data, including a 3D conductivity block model and RL elevation slice images .

Conductor plate modelling of the VTEM and DHEM data was completed to assist with targeting and drill
planning. Cross validation of the re-modelled data against known geology, surface geochemistry, previous
drilling, and historical mine workings was carried out by CopperCorp Geologists.
The work confirmed the presence of a significant VTEM anomaly at Jasper Hills with a strike length of
approximately 1,000m (Figures 2 and 3) , interpreted to be related to a low angle SW-dipping bedrock
conductor source. Conductor plate modelling of the VTEM and DHEM survey data for this anomaly further
supported the interpretation of a low angle SW -dipping bedrock conductor (Figure 3). Despite historical
drilling efforts at the prospect, including SJ -1 (Stellar Resources, 2013), the modelled VTEM and DHEM
conductor plate targets remain untested and have not been adequately explained. Our analysis is that
the up -dip projection of the interpreted bedrock conductor s is potentially consistent with high -grade
copper-gold mineralisation in surface outcrops of the old Jasper mine area and validates the VTEM
anomaly as a prospective and compelling drill target.
PROPOSED DRILL PROGRAM
An initial 2 hole, 750m diamond drilling program has been designed to test the EM conductor targets at
Jasper Hills (Figure 2) with all environmental and regulatory approvals successfully in place .
Environmental surveys have been completed, and formal approvals have been received. The area is well
accessed by sealed bitumen road to within 1.5km and then by a network of unsealed 4WD tracks.
Next Steps
• Planning is underway for clearing of drilling access tracks and pad preparation.
• Ground-based geophysical surveys are being considered to refine the geometry and continuity of
the anomaly prior to drilling.
• Geological mapping and sampling surveys have been recommenced to further enhance targeting
confidence and identify other potential targets in the prospect area.

About the Jasper Hills Prospect
The Jasper Hills prospect is located within Exploration License EL1/2020, situated approximately 10km
east of the operating Savage River magnetite mine and approximately 35km northwest of the Hellyer VMS
deposit (16.9Mt @ 13.8% Zn, 7.2% Pb, 0.4% Cu, 2.5g/t Au and 167g/t Au)5. The prospect area is accessed
by sealed bitumen road to within 1.5km and then by a network of unsealed 4WD tracks. Electrical
transmission lines pass by the prospect area along the main access road.
Bedrock geology of the area is dominated by Cambrian mafic to ultramafic and volcanic -sedimentary
sequences. Ordovician to Silurian sediments, Tertiary basalts and Quaternary sediments cover relatively
minor parts of the property. The Devonian aged Meredith granite underlies much of the southern part of
the tenement.
The prospect area includes a cluster of historical open pit and underground copper workings developed
on near-surface high-grade copper-gold lodes at the Old and New Jasper mines during the early 1900’s.
Mineralization-alteration styles and lithological associations at Jasper Hills indicate the area is prospective
for volcanogenic massive sulphide (VMS) deposits.
