CopperCorp Officially Granted Razorback Cu-
Au-REE License in Tasmania, Plans Drill
Campaign for Q4 2023
Vancouver, British Columbia--(Newsfile Corp. - September 20, 2023) - CopperCorp Resources Inc.
(TSXV: CPER) (OTCQB: CPCPF) ("CopperCorp" or the "Company") is pleased to announce that it has
been granted new exploration license application EL8/2023 (Razorback) located in western Tasmania,
Australia. The Razorback property and existing EL16/2018 (Walford Peak) and EL24/2020 (High Tor)
properties have been consolidated into an expanded Skyline Project to form a district-scale Cu-Au-REE
opportunity.
Highlights
Newly granted EL8/2023 (Razorback) property comprises 171km
2
, located directly south along
strike of the Mt Lyell copper-gold mine (approximately 3Mt contained copper and 3Moz gold).
Highly anomalous Cu-Au and REE mineralization in previous drill hole intercepts include:
30.0m @ 2.1% TREO (Total Rare Earth Oxides) from 297m, including 5m @ 3.03%
TREO from 311m
(SDD005, South Darwin prospect)
1
Within this 30.0m intersection high-value magnet rare earth oxides (MREO)
comprise 25% of the TREO (0.53% MREO)
13.0m @ 1.2% Cu and 0.45g/t Au
from 345m (SDD005, South Darwin prospect)
1
13.4m @ 1.6% Cu and 1.6g/t Au
from 61.6m (JP02, Jukes prospect)

Drill targeting and planning underway with drilling anticipated to commence in Q4, 2023 subject to
permitting, approvals and availability of drill rigs.
High-value magnet rare earth oxides (MREO), including neodymium (Nd) and Praseodymium (Pr)
confirmed in South Darwin prospect REE mineralization.
Multiple highly prospective REE and Cu-Au target areas identified as priority exploration targets.
Re-sampling of historical drill core has commenced - the majority of historical drill holes were not
systematically assayed for REEs.
The expanded Skyline Project now comprises three 100%-owned exploration licenses covering a
combined area of 504km
2
consolidating the Company's land holding over a district-scale IOCG
system with affinities to the Candelaria IOCG region in Chile.
Stephen Swatton, President and CEO of CopperCorp, commented:
"The granting of Razorback provides an extremely important and significant addition to CopperCorp's
precious and base metals portfolio. Historical drilling at the Darwin zone has discovered high grade
Cu-Au-REE mineralization with high grade intercepts of up to 30m @ 2.1% TREO which includes a
significant percentage high-value magnet rare-earth minerals such as neodymium and
praseodymium.
We will commence boots-on-ground exploration at the earliest opportunity and plan to drill as soon as
possible when permitting is complete."
Expanded Skyline Project
The Skyline Project (Figure 1) has been expanded to include the newly granted Razorback property as
well as the existing EL18/2018 and EL24/2020 properties and now covers a combined area of 504km
2
,
giving the Company a dominant land position covering 80km of combined strike length over the eastern
margin of the highly mineralized Cambrian-aged Mount Read Volcanics (MRV) belt and its northern
correlates.
The Company considers the project area to be highly prospective for iron oxide-copper-gold
(IOCG) and rare earth element (REE) deposits.
Four large-scale mines occur within 10km of the properties now comprising the consolidated Skyline
Project - including the Tier 1 Mount Lyell Cu-Au deposit (3 Mt contained Cu and 3 Moz contained Au @
1.0% Cu and 0.3g/t Au)
2
, the world class Rosebery and Hellyer polymetallic VMS deposits, and the
Henty Au deposit (1.64 Moz Au @ 12.5 g/t Au)
2
(Figures 1 and 2).
EL8/2023 Razorback Property
The Razorback property covers 171km
2
of highly prospective ground situated directly south of the Mt
Lyell copper project. The property was awarded to the Company following its submission through the
state's Exploration Release Area (ERA) competitive application process
1
and was formally granted the
exploration license for a period of 5 years (renewable) commencing 23
rd
August 2023.
CopperCorp has identified three high-priority exploration target areas as well as other lower priority
areas within the Razorback property (Table 1, Figure 3).
The high-priority Jukes, Hyde and Darwin zone
target areas will be the focus of initial exploration efforts commencing soon.

Darwin Zone
The Darwin zone target, located in the southern portion of the license is defined by a 7km long north-
south trending coincident magnetic and potassium-thorium radiometric anomaly.
Previous drilling into
part of this extensive anomaly at the South Darwin prospect intercepted significant IOCG style Cu-Au
and REE mineralization associated with north-south trending hydrothermal breccias comprised of
magnetite-hematite-pyrite-chalcopyrite-bornite mineralization hosted in intensely K-feldspar-chlorite-
tourmaline altered volcanics directly adjacent to intrusive granites and porphyry bodies.
The
mineralization at South Darwin remains open at depth and along strike, and with the previous drilling
testing less than 10% of the 7km-long anomaly, the Company considers there to be excellent further Cu-
Au and REE discovery potential at Darwin.
The IOCG style mineralization drilled at South Darwin comprises vein, breccia and semi-massive to
massive magnetite-pyrite-chalcopyrite (Figures 5 and 6). The previous drilling returned a best intercept
of
13.0m @ 1.2% Cu and 0.45g/t Au
from 345m (SDD005)
1
(Figure 4).
Drill hole SDD005 also
intercepted significant rare earth element and scandium mineralization, including an intercept of
30.0m
@ 2.1% TREO and 73ppm Sc from 297m
,
including 5.0m @ 3.3% TREO and 98ppm Sc from
311m
(Figure 4, Table 2).
There are indications that the Cu-Au and REE grades are increasing with
depth at South Darwin and the Company is currently planning to drill test this concept in the coming
months ahead.
Historical drill assays indicate that the REE mineralization at South Darwin is enriched in critical listed
and valuable REE minerals. Approximately
25% of the total rare earth oxide suite in hole SDD005
comprises higher value REE. The grade of high value REE in this hole is 0.53% MREO
.
Further potential for REE mineralization in the South Darwin area is indicated by historical surface rock
chip sampling assay, with up to
16.2% TREO
recorded. Much of the northern part of the Darwin Zone
trend remains untested for REEs, however, extensive areas of thorium anomalism in radiometric data
indicates good potential for further REE mineralization to be defined.

Hyde Zone
The Hyde Zone is located 2.5km north along strike of the Darwin Zone and is interpreted to represent a
continuation of the Darwin Zone trend, with the intervening section being covered by overlying rock
sequences. The main target area at Hyde Zone comprises a 1.5km long magnetic, radiometric and
gravity high anomaly that is interpreted to be indicative of possible IOCG mineralization.
While the target
area remains historically untested, extensive areas of outcropping chlorite-sericite alteration with
disseminated and stringer vein pyrite-chalcopyrite mineralization flank the western and eastern sides of
the magnetic-radiometric-gravity anomaly with surface rock chip sampling in the 1970's returning assays
including
0.5 to 1.25% Cu over 24m
2
, and up to
6.1% Cu and 3.9g/t Au
2
from outcropping gossan.
Jukes Zone
At the Jukes zone area, located 10km south of the Mt Lyell copper mine, historical small-scale mining
during the early 1900's was carried out on high-grade copper-gold magnetite-sulphide pipes with
several exploration adits and shafts developed throughout the general area.
The IOCG style mineralization at Jukes is hosted in a zone of K-feldspar-magnetite alteration which is
overprinted by a later mineralization phase chlorite-magnetite-pyrite-chalcopyrite event and an outermost
zone of sericite-chlorite alteration extending vertically and laterally away from an intrusive granite source
situated approximately 1km below surface.
Drilling below historical workings at Jukes in the 1970's gave a best intercept of
13.4m @ 1.6% Cu and
1.6g/t Au
from 61.6m (drillhole JP02)
1
and channel sampling of historical adits returned further high-
grade results including
16m @ 1.7% Cu and 1.4 g/t Au
,
9m @ 1.55% Cu and 1.56 g/t Au
and
2m @
5.68% Cu and 5.8 g/t Au
.
No further drilling has been carried out despite extensive surface exploration
identifying broad alteration zones and outcropping mineralization with coincident anomalous magnetics
and IP chargeability features extending northwards from the area of historical mining and drilling.
