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.
High-grade intercepts, including
10.0m @ 1.2% Cu
and
4.9m of 1.5% Cu in AP030,
and
5.0m of
2.06% Cu in AP034
, indicate the potential for accumulations of higher-grade copper within the
larger Alpine Stellar target area, including to depth.
These results continue to define multiple broad, sub-parallel dipping zones of mineralization at the
Alpine Stellar zone with average copper grades in the 0.3% to 0.7% range.
Recently completed deep drill holes AP035 and AP036 (assays pending) both successfully
intersected intervals of significant visual copper sulphide
1
mineralization up to 200m below
previous drill holes.
Copper mineralization at the Alpine Stellar zone has now been defined over a strike length of
600m and to a depth of 400m from surface. The mineralization remains open at depth and along
strike.
A geological review of the Alpine Stellar zone has commenced ahead of finalizing 3D models that
will be used to plan future extension drilling at the Stellar zone.
The drill rig has been relocated to the Alpine West target, located approximately 500m along strike
to the west from the Alpine Stellar zone. Drilling of AP037 has commenced on this previously
untested target as the first hole of an initial scout drilling program comprising 4 diamond holes at
Alpine West.

Sean Westbrook, CopperCorp's Vice President of Exploration, commented:
"The recent drill results from Alpine Stellar zone have delivered strong copper intercepts over
significant widths, and importantly, we are starting to see more high-grade intervals from drilling as our
knowledge base develops and we vector towards the stronger parts of the Stellar system.
Encouragingly, recent drill holes AP035 and AP036, targeting depth extensions beneath previously
drilled mineralization, have both intersected significant intervals of what we think is visible copper
sulphide mineralization
1
. The team eagerly awaits the assay results from these holes, which will be
reported once received and reviewed.
The Company is pleased to have commenced drilling at the Alpine West prospect which will represent
the first ever drilling at this location, which is approximately 500m west along strike from the Stellar
zone.
Alpine West is an exciting target with the potential to significantly expand the mineralization
footprint at Alpine.
In conjunction with the Alpine West drilling, the exploration team has commenced a geological review
of the Stellar zone ahead of finalizing 3D geological models that will form the basis for the next round
of drill planning at Stellar. As demonstrated by the recent drill results, the Stellar zone holds excellent
exploration upside potential and future work programs will be designed to vigorously pursue this
growth upside. In terms of a growth story, it is still early days for Alpine and as can be seen in the drill
section figures, increased drill hole density has a marked positive impact on defining higher-grade
mineralization zones at Stellar.
On a district scale, it is pertinent to note that the currently drilled Alpine prospect area covers less than
1% of the IOCG prospective Arthur Metamorphic Complex (AMC), which has a strike length of 100km
and over which CopperCorp holds a dominant tenement position with 1066km
2
in granted tenements
(see Figure 15). The Company has identified a pipeline of multiple regional copper and gold
exploration target zones along and adjacent to the AMC trend and we look forward to reporting on
these in the coming months. Field reconnaissance sampling was recently commenced over high
priority regional targets with first assay results expected within 4 to 6 weeks."
Alpine Prospect Drilling Update
The Company's first round of drilling at the Alpine Stellar zone is now complete, with a total of 16
diamond holes drilled for a total of 5,490m. The Stellar zone drill program comprised infill and step-out
holes designed to test the extent and continuity of the mineralizing system and investigate vectors
towards targeting high-grade portions of the system.
The drill rig has now moved 500m to the west (the Alpine West zone) and commenced drilling of hole
AP037 (Figure 1) targeting a combined magnetic-gravity anomaly and coincident copper in soils
anomalous zone interpreted to be a possible strike extension to the Alpine Stellar zone mineralization
(refer to previous news release dated April 27, 2022 for further details on the Alpine West target).
New assay results from 7 drill holes AP028, AP029, AP030, AP031B, AP032, AP033 and AP034 have
been received and reviewed. Most holes were successful in intersecting zones of significant copper
mineralization (Table 2).
AP028
, drilled to 459.9m total length, was designed to test strike extensions to the east of mineralization
encountered in hole AP027A (see news release dated June 8, 2022).
The drill hole successfully
intercepted three zones of copper mineralization, including
7.0m @ 0.46% Cu
from 55.1m,
20.0m @
0.51% Cu
from 248m, and
64m @ 0.26% Cu
from 296m (Figure 6).
The upper zone, representing an
interpreted eastern extension of the hanging wall magnetite-pyrite-siderite lens, had a lower faulted
contact which supports the interpretation of a structurally controlled eastern boundary to the hanging wall
lens in this area of the system.
AP029
, drilled to 247.0m total length on the same section as AP028, was designed as an infill hole
testing mineralization between AP006
2
and AP027A
5
. The drill hole successfully intercepted magnetite-
pyrite-siderite ironstone hosted and disseminated, blebby and vein style mineralization returning an
intercept of
71.0 @ 0.38% Cu
from 133m (Figure 6, see mineralized drill core example in Figure 7).
AP030
, drilled to a total length of 364.0m, was drilled as an infill hole between historical drillholes
AP006
2
,
4
and AP013
2
,
4
.
AP030 (Figure 8) successfully intersected multiple zones of mineralization,
including
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,
18.0 @ 0.70% Cu
from
307.0m including a high-grade zone of
4.9m @ 1.5% Cu
from 312.1m (see example of high-grade drill
core in Figure 9).
AP031B
, drilled to 424.0m total length, and
AP032
, drilled to 328.0m total length, were both designed to
test for eastern strike extensions of the Stellar zone mineralization.
Both holes intersection narrow zones
of low to moderate grade copper mineralization including; AP031B:
7.0m @ 0.44% Cu
from 227.0m
and
4.1m @ 0.34% Cu
from 386.0m; and AP032:
6.0m @ 0.13% Cu
from 122m,
3.7m @ 0.57% Cu
from 136.3m, and
26.0m @ 0.11% Cu
from 228.0m.
A northwest trending fault (the Duck Creek Fault -
Figure 10) is currently interpreted to be truncating or offsetting the eastern extension of the Stellar zone in
the vicinity of AP031B and AP032.
AP033
, drilled to 429.5m total length, was designed to test down-dip extensions to mineralization
encountered in holes AP027A
5
, AP017
2
,
4
, AP011
2
,
4
and AP004
2
,
4
(Figure 3).
The drill hole
successfully intercepted two zones of mineralization, including
32.5m @ 0.59% Cu
from 270.5m, and
82.2m @ 0.33% Cu
from 347.3m to end of hole (EOH)
including 10.5m @ 0.75% Cu
from 419.0m to
EOH.
The AP033 results extend copper mineralization by approximately 60m down-dip of hole AP017
(24.7m @ 0.52% Cu from 222m) and 240m down-dip of hole AP004 (38.2m @ 0.79% Cu from 57.7m
4
,
including 28.2m @ 1.03% Cu from 58.7m
4
).
AP033 ended in high-grade disseminated, blebby and vein
style copper mineralization grading 0.75% Cu over the final 10.5m of the hole but unfortunately the hole
had to be terminated due to technical issues associated with fault zones in the upper parts of the hole.
AP034
, drilled to 460.0m total length on the same section as AP033, was designed as an infill hole
(Figure 3).
The hole successfully encountered multiple zones of mineralization, including
31.6m @
0.64% Cu
from 177.7m
(
including
5.0m @ 2.06% Cu
from 187.0m - see examples of high-grade drill
core in Figures 4 and 5),
9.0m @ 0.42% Cu
from 258.0m,
19.0m @ 0.23% Cu
from 285m, 76.0m @
0.23% Cu from 322m, and 3.0m @ 0.24% Cu from 452m.
AP035
(
assays pending
), drilled to 447.8m total length, was designed to test down-dip extensions to
mineralization encountered in hole AP024
4
(including 42.1m @ 0.60% Cu from 55.9m, 6m @ 0.96% Cu
from 133m, and 43m @ 0.33% Cu from 157m
4
).
AP035 successfully intercepted variably chalcopyrite
1
mineralized ironstone (magnetite-pyrite-hematite-siderite) zones at 217.2 to 232.5m and 241.5 to
255.4m depth down hole (see drill core example in Figure 11), and then intermittent trace to
disseminated, blebby and stringer vein style chalcopyrite mineralization zones associated with quartz-
siderite alteration and veining to 430.7m downhole (see drill core example in Figure 12).
AP035 was
terminated due to technical issues associated with a +5m wide graphitic shear zone from 442.4m.
AP036
(
assays pending
), drilled to 600.1m total length, was designed to test for possible northeast
strike extensions to the Stellar zone mineralization at depth below hole AP030 (see above).
AP036
successfully intercepted variable intensity (trace to moderate) disseminated, blebby and vein style
chalcopyrite
1
mineralization zones associated with quartz-siderite alteration and veining from 334.8m to
end of hole with zones of chalcopyrite mineralized ironstone (magnetite-pyrite-hematite-siderite) at 336.8
to 341m and 394.3 to 415.2m down hole (see mineralized drill core examples in Figures 13 and 14).

Note: The Company cautions that with respect to any visible chalcopyrite (copper sulphide) or other
visual mineralization indicators, such as the occurrence of other sulphide or oxide minerals, visual
observations and estimates are uncertain in nature and should not be taken as a substitute for
appropriate laboratory analysis. Laboratory assay results will be reported when they have been
received, validated, and interpreted.
Future Program
As the drilling proceeds into the Australian summer the Company will continue to drill the Alpine West
zone whilst awaiting the assay results from drill holes AP035 and AP036 from the Alpine Stellar zone. A
geological review of the Alpine Stellar zone has commenced ahead of finalizing 3D geological models
that will form the basis for the next round of drill planning at Alpine Stellar zone.
In addition to the ongoing exploration work at the Alpine prospect, the Company has commenced field
reconnaissance sampling at priority regional exploration target areas within the AMC project and is in
the process of planning a maiden drill campaign at the Dora prospect within the Skyline Project
