Vancouver, British Columbia--(Newsfile Corp. - April 26, 2023) - CopperCorp Resources Inc. (TSXV:
CPER) (OTCQB: CPCPF) ("CopperCorp" or the "Company") is pleased to report that high-grade
polymetallic assays have been returned from reconnaissance rock chip sampling at the Jasper Hills
prospect. The prospect is one of multiple new exploration target areas recognized within the Company's
AMC Project located in the 100% renewable energy state of Tasmania, Australia.
HIGHLIGHTS
Rock chip sampling program has confirmed highly anomalous copper-gold and polymetallic zinc-
lead-silver-tin mineralization at the Jasper Hills prospect.
Assays up to
16.45% Cu
and
10.1g/t
Au returned from sampling of historical copper prospects.
Assays up to
37.9% Zn+Pb
,
612g/t Ag
and
1.05% Sn
returned from sampling of historical silver
prospects.
CopperCorp has accelerated regional exploration activities with field work commenced to assess
up to
23 new priority Cu-Au exploration target areas
identified over the AMC Project.
Jasper
Hills is the first of the regional target areas to be tested.
Follow-up exploration at Jasper Hills is now underway.
Scout drill program at Dora prospect recently completed (2 holes for 788.7m) with assays pending.
Planning for deep drilling program at Alpine prospect in progress.
Sean Westbrook, Vice President of Exploration of CopperCorp commented:
"Jasper Hills is the first regional exploration target that the Company has tested at the AMC Project
outside of the flagship Alpine prospect and the confirmation of significant high-grade polymetallic
mineralization from the first pass sampling is highly encouraging and warrants follow-up exploration.
The results are interpreted to represent two distinct metallogenic events that have overlapped in close
proximity. In a mineral province renowned for its diversity of deposit styles, these early results at
Jasper Hills reaffirm the Company's belief in the district-scale potential of the AMC project to host
significant new discoveries."
JASPER HILLS ROCK CHIP SAMPLING PROGRAM
CopperCorp geologists recently carried out reconnaissance mapping and grab rock chip sampling over
parts of EL1/2021, with a total of 45 samples collected in the Jasper Hills prospect area (Figure 1). The
samples were collected from rock dumps, outcrops, and surface rock float in and around historical small-
scale mine workings and prospects throughout the Jasper Hills area (see Figures 2 and 3).
Out of the 45 rock samples, 27 were collected over areas of historical copper-gold prospects and 18
were collected over areas of historical silver (base metal) prospects. Sample details and key assay data
are presented in Tables 3, 4, 5 and 6.
Assay results from the sampling confirm the presence of highly anomalous copper-gold and zinc-lead-
silver-tin mineralization systems at Jasper Hills.
Copper-Gold Prospects Sampling
14 of the 27 rock chip samples from the copper-gold mineralization zones at Jasper Hills returned assay
results in excess of 1% Cu (Table 1), typically with coincident anomalous gold and silver values. Best
sample assays include
16.5% Cu with 0.23g/t Au and 133g/t Ag
(sample 63001),
14.4% Cu with
1.34g/t Au and 129g/t Ag
(sample 63008),
3.12% Cu with 2.08g/t Au and 40g/t Ag
(sample 63034),
and
1.67% Cu with 10.1g/t Au
(sample 63023). The anomalous samples were collected over a zone
approximately 1,600m by 700m in area (Figure 2).
The copper-gold mineralization at Jasper Hills occurs as vein and disseminated to blebby primary
chalcopyrite and secondary bornite, covellite, chalcocite and malachite (see Figures 5 and 6) hosted in
variably silica altered basalt, pyroxenite and sedimentary rocks. The Cu-Au mineralization is currently
interpreted to be of probable primary magmatic/volcanogenic origin and stratabound in nature
(Cambrian aged) with possible later remobilization and upgrading in structurally hosted positions during
Devonian age granite intrusion events.

Base Metals Prospects Sampling
10 of the 18 rock chip samples from the base metals prospect areas at Jasper Hills returned assay
results in excess of 8% Zn+Pb (Table 2) with coincident anomalous silver and tin values. Best sample
assays include
30.0% Zn with 7.9% Pb, 612g/t Ag and 0.83% Sn
(sample 63029),
10.25% Zn with
6.77% Pb, 320g/t Ag and 0.34% Sn
(Sample 63019), and
6.67% Zn with 3.89% Pb, 202g/t Ag and
1.05% Sn
(Sample 63014).
The base metal zone rock samples were taken over a strike length of approximately 1,200m (Figure 3).
Sampled areas include those of the historical Mount Wright, Heazlewood and Leven Creek prospects
which lie on northwest trending fault structures within altered ultramafic host rocks approximately 700-
1000m to the northeast of the main historical Cu-Au prospects. The structurally hosted mineralized
galena-sphalerite-cassiterite-quartz-carbonate vein lodes are typically 1-5m wide, comprising variable
banded to massive vein and disseminated styles of mineralization (see Figures 7 and 8).
Historically,
these lodes were selectively mined to shallow levels (30-60m) for high-grade silver associated with
discrete narrow galena veins within the wider lode, with any mixed sulphide ore mostly discarded.

JASPER HILLS - BACKGROUND
The Jasper Hills prospect is located within Exploration License EL1/2020, situated approximately 10km
east of the operational Savage River magnetite mine and approximately 35km northeast of
CopperCorp's Alpine prospect (Figure 1).
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.
Historical prospecting and mining in the area, commenced during the 1880's, was initially focused on
silver lodes of the Mt Wright-Heazlewood and Mt Stewart (approx. 4km south of Jasper Hills) mines and
then periodically for copper at the Old Jasper and New Jasper prospects following the discovery of
outcropping copper mineralization around 1898.
9
Intermittent copper prospecting and small-scale
mining was mainly carried out on near-surface high-grade oxide lodes at the Old and New Jasper mines
until around 1920, however, limited records are available.
It is estimated that approximately 200 tons of
handpicked copper ore ("firsts") and concentrates grading approximately 20% Cu and 6g/t Au was
produced from the Old and New Jasper workings post-1912
9
.
Available records indicate that around
300 tons of lead-silver-zinc ore averaging approximately 65% Pb and 2,740g/t Ag was extracted from
the various Mt Wright-Heazlewood workings.
9
Copper-gold mineralization at Jasper Hills occurs as vein and disseminated to blebby primary
chalcopyrite and secondary bornite, covellite, chalcocite and malachite hosted in variably silica to
jasperoid altered basalt, pyroxenite and sedimentary rocks. The copper-gold mineralization is
stratabound to fault-hosted in nature and is interpreted to be of probable Cambrian age primary
magmatic/volcanogenic origin with possible later remobilization and upgrading into structurally hosted
positions during Devonian granite intrusion events.
The historical silver-lead-zinc prospects of Mt Wright, Heazlewood and Leven Creek occur on a
northwest-trending structural zone in altered mafic ultramafic rock units. The structurally hosted
mineralized vein lodes are typically 1-5m wide, comprising variably banded vein and disseminated
sphalerite-galena-quartz-carbonate mineralization. These lodes were historically mined to shallow levels
and selectively for high-grade silver associated with discrete narrow galena veins, with any mixed
sulphide ore mostly discarded as waste. The prospects have remained untested by drilling.
Tin mineralization has not previously been recognized in the Jasper Hills area.
However, several
significant tin mines occur within 20km, including Mount Bischoff (10.54 Mt @ 1.1% Sn), Cleveland (12.4
Mt @ 0.61% Sn & 0.25% Cu), and Magnet (0.63 Mt @ 427 g/t Ag, 7.3% Pb & 7.3% Zn) mines.
10
Numerous companies have carried out various exploration activities over the Jasper Hills area since the
1960's, however, most of the work can be regarded as superficial in nature.
Results of available previous
soil data are shown in Figure 2.
Limited historical drilling at Jasper Hills includes 14 shallow RC holes (totaling 483m) drilled in 1988 and
4 diamond core holes (totaling 620.5m) drilled between 1988 and 2013. Results of the RC drilling were
considered inconclusive due to most holes not reaching the target depths and the program being
abandoned due to drilling difficulties.
The historical diamond drill holes were selectively sampled (varying
from 1% to 55% of core sampled from individual drill holes) with best results including 3m @ 2.05% Cu
from 115m in hole JD2, 0.3m @ 2.25% Cu, 6.6g/t Ag and 0.28g/t Ag from 26.3m in hole JD3, and 0.23m
@ 0.82% Cu and 0.19g/t Au from 101m in hole SJ-1.
Multiple geophysical surveys, including ground magnetics, IP, SP, airborne magnetics, DIGHEM, and
VTEM have been carried out over the Jasper Hills and wider tenement area, and the Company has
commenced a review of available open-source data.
Next Steps
Results of the rock chip sampling program at Jasper Hills have confirmed high mineralization grades that
warrant follow-up assessment work. Activities in-progress include finalization of historical data
compilation, reprocessing and modeling of available geophysical data, detailed geological mapping and
additional sampling.
REGIONAL TARGETING REVIEW
As previously announced
8
, recent data compilation and review work undertaken for CopperCorp's AMC
Project has identified 23 priority Cu-Au exploration target areas. The primary exploration target is for
iron-oxide-copper-gold (IOCG) style mineralization, however, potential for other mineralization styles was
also recognized during the review, including polymetallic volcanogenic and intrusion related
mineralization. The review involved compilation and review of available open-file geological,
geophysical, surface geochemistry, and historical drilling data, with independent Australian geophysical
consultants, Resource Potentials, engaged to assist with re-processing and interpreting available
geophysical data as part of the review.
The AMC Project covers 1,066km
2
of ground over the Arthur Metamorphic Complex (AMC), a
Neoproterozoic-Cambrian regional-scale metamorphic structural deformation zone that is host to
widespread magnetite-sulphide-silicate alteration and mineralization indicative of a large IOCG-style
system
2
and includes the Savage River 498 Mt @ 46% DTR magnetite mine (owned by Grange
Resources Limited)
1
and CopperCorp's Alpine copper prospect.
2-
7
Many of the identified target areas are either previously unexplored or under-explored in modern times.
Permitting for the follow-up exploration work programs is currently in-progress for priority regional target
areas within the AMC Project.
Stephen Swatton, President and CEO of CopperCorp commented:
"The results of the regional review and targeting exercise support our earlier interpretations for a
prospective district-scale Cu-Au corridor along the Arthur Metamorphic Complex (AMC) and adjacent
areas, including IOCG and volcanogenic style targets, and will underpin our regional exploration
strategy for the AMC Project where significant widths of copper mineralization have already been
intersected in drilling at the Company's Alpine prospect.
With approximately C$6.0M in cash the Company's strategy is to continue with its plan to drill Alpine
in a cost-effective manner while undertaking targeted exploration within the AMC and Skyline Projects
at prioritized areas."
OTHER BUSINESS
Dora Prospect Scout Drilling Update
The Dora prospect scout drill program
8
was completed on 14
th
April, 2023. The completed drilling
comprised 2 diamond drillholes for a total of 788.7m at the Dora 3 target area.
The Dora 3 target area
comprises an elongate zone, some +500m in strike length (open), of outcropping mineralization with
anomalous assays from historical and recent rock sampling including 1.03% Cu with 0.4g/t Au
8
.
The drill
core is currently being processed and sampled, and results will be reported following receipt of assays
in due course.
Alpine Prospect Update
Assays from the first two diamond drill holes at the Alpine West prospect maiden drill program have
been received.
Results are still being reviewed and interpreted, however, no significant mineralized
intercepts are evident from the assay results.
The gravity anomaly at Alpine West
3
remains unexplained
from the recent drilling and the Company plans to update the Alpine prospect geophysical models based
on new drill hole information as part of a general prospect wide review.
Planning and permitting is currently underway for a deep drill program at the Alpine Stellar zone prospect
where CopperCorp has already confirmed the continuation of high-grade copper mineralization from
surface to depths of at least 400m (e.g.
AP036: 23m @ 1.14% Cu from 292m, within 90.0m @
0.50% Cu from 334.0m
7
). Further updates and details of the planned deep drill program will be
reported in a later news release.
Board Resignation
The Company also announces that effective immediately, Aaron Keay has resigned as a member of the
board of directors of CopperCorp. The board of directors would like to take this opportunity to express
its sincere appreciation to Mr. Keay for his valuable contributions and services to the Company.
