CopperCorp Samples 31.0m at 1.48% Cu & 0.83 g/t Au
at Jukes Prospect, Significant Scale Potential Identified
VANCOUVER, BC May 13, 2024 – CopperCorp Resources Inc. (TSXV: CPER) (OTCQB: CPCPF) (“CopperCorp”
or the “Company”) is pleased to provide results of channel and rock chip sampling at the Jukes Cu -Au
prospect, Razorback license in western Tasmania, Australia. Ch annel sampling in an early 20 th Century
mine adit by CPER, with intersections of up to 9.0m @ 2.92% Cu, 1.79 g/t Au and 10.17 g/t Ag, confirm
historically reported high-grade Cu-Au mineralization at the prospect.
HIGHLIGHTS
● Assay results received from sampling of historical underground adits have confirmed high -grade
copper-gold potential at the Jukes prospect, including significant intervals:
Mineralized Zone Interval (m)* Cu (%) Au (g/t) Ag (g/t) From
(m)
J3West Zone 31.0 1.48 0.83 5.21 8
including 9.0 2.92 1.79 10.17 8
J3East Zone 26.0 0.65 0.67 2.60 72
*Intervals are along-channel sample widths. True widths are not known at this time.
● Results from 14 outcrop rock chip samples taken along the interpreted strike of the underground
sampled mineralization include individual assays up to 46.6% Cu and 9.54g/t Au.
● Modelling of magnetic data suggests a magnetic pipe feature associated with the Jukes Cu-Au
system extends up to 700m along strike and up to 1,400m below surface, indicating potential for
the mineralization system to have significant scale. The magnetic pipe is untested by drilling.
● Mineralization and alteration styles identified at Jukes, as well as the copper and gold mineral
tenor are consistent with the large Mt Lyell Cu -Au system (311Mt @ 0.97% Cu and 0.31g/t Au)
located 10km to the north of Jukes. The gold:copper ratio at Jukes is typically 3-4 times that of the
Mt Lyell orebodies.
● Environmental surveys completed and initial drill program permitting approvals received.
Stephen Swatton, President and CEO of CopperCorp commented: “The Jukes prospect is a compelling
high-grade copper-gold drill target close to surface and approximately 10km south and along trend from
the famous historical Mt Lyell Cu-Au mining camp. The Mt Lyell mine licenses are currently the subject of
550-800 West Pender St. Vancouver, BC V6C 2V6 | E: [email protected] | W: coppercorpinc.com
a feasibility study by Sibanye Stillwater Ltd. who report that resources of at least 1 million tonnes copper
and 1 million ounces gold are still present at the site.
CopperCorp’s high grade, near surface mineralization at the Jukes no.3 adit, combined with a geophysical
magnetic feature that extend s to about 1,400 metres below surface has developed into a convincing
target that has not been drill tested since a limited program undertaken some 40 years ago. The Mt Lyell
camp is interpreted as a cluster of deposits ( Figures 1 and 2) with porphyry/epithermal style affinities at
the upper levels of an IOCG system . Jukes is interpreted by CPER as a probable deeper extension of the
same rock suite. In addition to Jukes, at least 6 other nearby prospects (Figure 3) on 100% held ground
are being investigated by CopperCorp geologists . This 25km long belt is interpreted to represent a
southern extension of the prolific Mt Lyell mine copper-gold system. New interpretation by CopperCorp
indicates that previous drilling at Jukes only tested the southern edge of mineralization at Jukes.
In summary the excellent work by CPER geologists has defined a ‘walk up’ copper-gold drill target at
Jukes and preliminary work on other zones definitely shows that the minerali zation across the
Razorback license has the potential to be of a district wide scale.
In late April the Company received permission to commence drilling Jukes with helicopter support,
however, as we approach the Tasmanian winter, we have also sought permission to construct vehicle
access to the initial proposed drill pads to enable year-round uninterrupted exploration.”

Jukes Adit Sampling
Assay results from a combined 158m of continuous channel sampling of historical underground workings
at the Jukes prospect have been received. The sampling was carried out along wall rocks of the Jukes No.
3 main adit and associated crosscuts which intersect two separate mineralized zones – the Jukes No. 3
West (J3West) zone and the Jukes No. 3 East (J3East) zone (Figure 4). Significant mineralized intervals
from the recent adit sampling are listed in Table 1. These results confirm the high-grade tenure of copper
and gold grades previously reported from drilling and underground sampling at the prospect (see Tables
4 and 5).

*Intervals are along-channel sample widths. True widths are not known at this time.
The historical adit and associated crosscuts intersect the mineralized zones at various angles and over
variable lengths; true widths of the mineralized zones are not known at this stage. Based on predominant
NNW-trending, steeply dipping orientation of the mineralized zones, J3West is interpreted to be 30-40m
wide, and J3East zone is interpreted to be 15-20m wide in the area of sampling.
Primary copper-gold mineralization at the Jukes prospect occurs predominantly as chalcopyrite and lesser
bornite, commonly associated with magnetite and pyrite. High-grade mineralization is developed in
strongly foliated to schistose, intensely chlorite altered host rocks (Figure 7 ). Secondary supergene
mineralization is variably developed near surface, comprising chalcocite, malachite, cuprite, digenite and
native copper (Figure 8).
Jukes Surface Sampling
Assays results have also been received for 14 rock chip samples taken during reconnaissance mapping in
the Jukes prospect area (Table 2). Most of the rock chip samples were taken from mineralized zones
outcropping along the interpreted strike of the J3West and parallel mineralized zones sampled in the
historical adits. Results indicate that the Cu -Au mineralized trend extends north for at least up to 270m
along strike (open) from the Jukes No.3 Adit sampling with 85% of samples being anomalous in copper
(>0.1% Cu) and 43% of samples returning grades over 1% Cu. Bonanza grades of copper have also been
recorded with 2 samples returning grades over 25% Cu with gold grades up to 9.54g/t Au. The mineralized
trend remains open along strike and further surface sampling is ongoing.

Jukes Geophysical Modelling
CopperCorp engaged Australian-based independent geophysical consultants, Resource Potentials Pty Ltd.,
to carry out magnetic and gravity data compilation, processing and 3D inversion modelling using available
open file regional and historical exploration geophysical data.
Results of 3D inversion modelling show the Jukes prospect is defined by an elongate pipe -like magnetic
high feature with the core of the pipe extending up to 700m in a N-S direction, and up to 1.4km vertically
below outcropping mineralization at surface (See Figure 5). The magnetic high (or core) is coincident with
the magnetite bearing Cu -Au mineralization sampled at surface and an enveloping zone of k -feldspar-
magnetite-pyrite alteration. The magnetic pipe is confined to the footwall (north) of the NE -trending,
steeply SE dipping Jukes Fault, also consistent with the position of mineralization. It is untested by drilling.
Previous Work and proposed work going forward in 2024
Historical (1970’s and 1980’s) drilling at Jukes was designed to test an early geological model that involved
mineralization being confined to the immediate footwall zone of the Jukes fault and has not tested the
potential of the interpreted larger NNW-trending mineralization system and structurally controlled high-
grade shoots now recognized by CopperCorp. It is interpreted that most historical exploration drilling was
focused on the southern edge of the larger mineralized system.
CopperCorp recently received Government approval for a proposed initial 1000m diamond drill program
at Jukes. The Company has also applied for road access and is awaiting confirmation of this more cost -
effective and convenient option. Proposed drilling in 2024 will target depth and strike extensions to the
sampled high-grade mineralization.
About The Jukes Prospect
At the Jukes prospect, located 10km south of the Mt Lyell copper mine, historical prospecting and small-
scale mining during the late 1890’s to early 1900’s was carried out on high-grade copper-gold magnetite-
sulphide mineralization with several exploration adits and shafts developed throughout the prospect area.
The small-scale mining was not extensive and was mostly ceased by 1903 when nearby smelters closed.

Drilling below historical workings at Jukes in the 1970’s and 1980’s gave a best intercept of 13.4m @ 1.6%
Cu and 1.6g/t Au from 61.6m (drillhole JP02) and channel sampling of historical adits returned further
high-grade results. Significant mineralized intercepts from the historical drill holes are listed in Table 4.
Significant mineralized intervals from the historical adit sampling are listed in Table 5. No further drilling
has been carried out at the prospect despite surface exploration identifying bro ad alteration zones and
outcropping mineralization with coincident anomalous magnetics and IP chargeability features extending
northwards from the area of historical mining and drilling.

Surface mapping by CPER indicates the hydrothermal alteration system at Jukes is characterised by K -
feldspar-magnetite alteration with extensive development of magnetite-apatite-pyrite stockwork veining
to semi-massive mineralization broadly coincident wit h the modelled magnetic pipe feature. The most
intensive magnetite-apatite-pyrite alteration is developed 400m north of the historical Jukes workings
550-800 West Pender St. Vancouver, BC V6C 2V6 | E: [email protected] | W: coppercorpinc.com
and all previous exploration drilling. Cu -Au mineralization is associated with an overprinting phase of
intense chlorite-magnetite-sulphide alteration that shows close spatial association with NNW -trending
fault structures and intersection of these structu res with the NE -trending Jukes fault. A sericite -chlorite
alteration zone occurs outbound of the inner mineralized K -feldspar-magnetite and chlorite -magnetite
zones. Primary copper mineralization at Jukes occurs predominantly as chalcopyrite and lesser bornite,
commonly associated with magnetite and lesser pyrite. The host rocks are dacitic volcaniclastic and lava
units of the Mt Read Volcanics.
The style of mineralization and alteration and the copper and gold mineral tenor at the Jukes prospect is
consistent with the deeper level orebodies of the nearby Cu -Au Mt Lyell system where the most
productive style of mineralization occurs as subvertical pipe-like disseminated-stringer chalcopyrite-pyrite
bodies associated with disseminated pyrite and chloritic -magnetite-apatite and minor potassic altered
rocks. The Prince Lyell orebody (>100Mt) at Mt Lyell ( Figure 2) is a subvertical pipe -like body with
dimensions of approximately 450 x 150 m at surface and is vertically continuous for more than 1500m.
Other Ongoing CopperCorp Work Programs
South Darwin Drilling Update
A second drill hole, SDD008, is currently underway at the South Darwin REE and Cu -Au target. The drill
hole depth is currently at 270m (May 12, 2024). The Results from drill hole SDD007 and extensive surface
sampling at South Darwin have been received and are currently under review. An exploration update
which will incorporate the results of SDD007, the ongoing drilling at SDD008 and surface sample analyses
is currently being prepared. This report will be available once all drill results are received and we have a
better understanding of the geology and possible genetic relationship to the Jukes and other prospects in
the Razorback license.
The Company is also undertaking preliminary investigations into the potential ease or difficulty of REE
extraction from the allanite-rich mineralization.
