Vancouver, British Columbia--(Newsfile Corp. - December 7, 2022) - CopperCorp Resources Inc.
(TSXV: CPER) (OTCQB: CPCPF) ("CopperCorp" or the "Company") is pleased to report new assay
results from two diamond drill holes at the Alpine prospect, part of its 100%-owned, 1,066 km
2
AMC
Copper Project located on a paved road approximately 30km from the regional hub of Zeehan, West
Tasmania, Australia.
Highlights
Assay results received for drillholes AP035 and AP036, drilled 400m apart, have confirmed
continuation of high-grade copper mineralization at depth below previous drilling at the Alpine
Stellar zone.
The deep mineralization zones in AP035 and AP036
include some of the widest high-grade
copper intercepts drilled to date at Alpine
, with significant mineralized intercepts including:

Note that true widths are uncertain.
Initial interpretation by the Company is that the copper mineralization is hosted in steeply dipping zones of
mineralization implying true widths in the range of 70% to 95% of reported intervals.
See full intercepts in Table 2.
These and other recently reported results

continue to indicate the potential for high-grade copper
zones within the broader mineralization envelope at Alpine Stellar zone, with indications that the
width of high-grade copper zones may increase with depth.
Copper mineralization at the Alpine Stellar zone is now defined over a continuous strike length of
600m from surface to 450m depth. The mineralization remains open at depth and along strike.
Drilling is ongoing at the Alpine West target, located approximately 500m along strike to the west
from the Alpine Stellar zone.
Stephen Swatton, President and CEO of CopperCorp, commented:
"I am extremely encouraged by these results; they confirm the anticipated continuity of significant
copper mineralization down dip at depths below 300m. This mineralization is open in multiple zones
along strike and to depth. The consistency of copper grades over significant widths with higher, plus
1% copper grade intervals now being encountered is very encouraging as we eagerly await assay
results from holes AP037 and AP038 which are located 500 metres to the west of the Alpine Stellar
zone.
"
Tasmania is one of the best jurisdictions in the world to have a mineral discovery - governmental
support, abundance of cheap power, proximity to industrial ports and a highly skilled local workforce in
an active mining district that is host to more than five operating gold and base metal mines sets it
apart from most global copper producing locations.
"
With receipt of these encouraging results the Company has decided to initiate preliminary resource
studies to determine the various possible scenarios for extraction in order to help guide future
drilling."

AP035
, drilled to 447.8m total length, was designed to test down-dip extensions to mineralization
encountered in hole AP024
3
(including 42.1m @ 0.60% Cu from 55.9m, 6m @ 0.96% Cu from 133m,
and 43m @ 0.33% Cu from 157m

). AP035 successfully intercepted two zones of copper mineralization,
including
45.0m @ 0.62% Cu from 217.0m
(
including 18.0m @ 0.9% Cu from 238.0m
), and 22.0m
@ 0.15% Cu from 409.0m. The upper mineralization zone from 217m consists of variably chalcopyrite
mineralized ironstone (magnetite-pyrite-hematite-siderite) zones at 217.2 to 232.5m and 241.5 to
255.4m depth down hole, while the low-grade intercept from 409m is associated with disseminated,
blebby and stringer vein style chalcopyrite mineralization zones and quartz-siderite alteration and veining
to 430.7m downhole. AP035 was terminated due to technical issues associated with a +5m wide
graphitic shear zone from 442.4m.
AP036
drilled to 600.1m total length, was designed to test for possible northeast strike extensions to the
Alpine Stellar zone mineralization at depth below hole AP030
6
(26.2m @ 0.53% Cu from 85.8m, 37.0m
@ 0.57% Cu from 181.0m including a high-grade zone of 10.0m @ 1.2% Cu from 185.0m, 8.0m @
0.25% Cu from 240m, and 18.0 @ 0.70% Cu from 307.0m including a high-grade zone of 4.9m @ 1.5%
Cu from 312.1m).
AP036 successfully intercepted two zones of copper mineralization, including
90.0m
@ 0.50% Cu from 334.0m (including 23.0m @ 1.14% Cu from 292.0m)
, and
64.0m @ 0.28% Cu
from 465.0m
.
Mineralization occurs as variable intensity (trace to moderate) disseminated, blebby and
vein style chalcopyrite associated with quartz-siderite alteration and veining from 334.8m, with zones of
chalcopyrite mineralized ironstone (magnetite-pyrite-hematite-siderite) at 336.8 to 341m and 394.3 to
415.2m down hole.
Alpine Drill Program Overview
The Company's maiden drill program at Alpine has focused on infill and extension drilling with a focus to
vector towards zones of thicker and higher-grade mineralization at the Alpine Stellar zone, and step-out
drilling to test the high-priority target at the Alpine West zone.
A total of 17 holes have been completed to
date.
The results of 13 CopperCorp drill holes (AP022 to AP034) and 21 historical drill holes (AP001 to
AP021) from the Alpine Stellar zone have been previously reported, with best significant intercepts from
these and newly reported results (this release) including:
AP004: 38.2m @ 0.79% Cu from 57.7m, including
28.2m @ 1.03% Cu from 58.7m
AP007: 86.0m @ 0.50% Cu from 62.0m, including
15.7m @ 0.82% Cu from 127.0m
AP017: 24.7m @ 0.52% Cu from 222.0m
AP022: 43.0m @ 0.62% Cu from 135.0m, including
17.4m @ 0.74% Cu from 159.7m
AP024: 42.1m @ 0.60% Cu from 55.9m, including
21.0m @ 0.76% Cu from 73.0m

AP027A: 54.2m @ 0.49% Cu from 34m, including 11.0m @ 0.79% Cu from 61.0m, and 106.0m
@ 0.31% Cu from 158m
AP030: 37.0m @ 0.57% Cu from 181.0m, including
10.0m @ 1.20% Cu from 185.0m
, and
AP030: 18.0m @ 0.70% Cu from 307.0m, including
4.9m @ 1.50% Cu from 312.1m
AP033: 32.5m @ 0.59% Cu from 270.5m, and

23.0m @ 1.14% Cu from 393m
Interpretation of the project geology to date suggests that the best high-grade copper zones at the Alpine
Stellar zone are associated with chalcopyrite mineralization in structurally controlled breccia zones
overprinting magnetite-hematite-pyrite ironstone units and in brittle fracture vein and breccia networks
overprinting intensely silica-albite altered metasediment host rock. The Company has commenced a
geological review towards refining the Alpine geological model with a particular focus on the high-grade
zones that will form the basis for targeting the next round of drilling at Alpine.
Alpine West Drilling Update
Drilling at Alpine West
2
(Figure 1) is ongoing with the first hole at the Alpine West target, AP037,
completed to a depth of 548.5m targeting magnetic and soil geochemical anomalies.
Logging,
processing, and sampling of AP037 has been completed prior and samples submitted to the lab.
A
second hole, AP038, was recently commenced at Alpine West targeting gravity and soil geochemical
anomalies.
Next Steps
The Company has commenced a geological review towards refining the Alpine geological model with a
particular focus on the high-grade zones that will form the basis for targeting the next round of drilling at
Alpine that will aim to prove up the continuity and down dip extension of high-grade copper zones.
Drilling is anticipated to recommence in Q2 2023 following drill hole planning and permitting.
The
Company will also commence preliminary metallurgical studies for Alpine.
In addition to the ongoing drilling and geological review work at Alpine, the Company has commenced
field reconnaissance sampling at priority regional exploration target areas within the AMC project
(Figure 11) and is in the process of permitting a maiden drill campaign at the Dora prospect within the
Skyline Project

,

planned for Q1 2023 subject to availability of drill rigs.
