*Exploration Target Cautionary Statement
The potential quantity and grade of the Exploration Target at Alpine Stellar are conceptual in nature. There
has been insufficient exploration to define a Mineral Resource, and it is uncertain whether further
exploration will result in the determination of a Mineral Resource. The Exploration Target has not been
evaluated for reasonable prospects of eventual economic extraction.

Alpine Stellar is CopperCorp’s most advanced exploration prospect within the AMC Project license block
area south of the Savage River iron ore mine. It is situated on the western side of the district that contains
the largest operating mines in Tasmania includ ing Renison Bell (Sn), Rosebery (Zn-Pb-Cu-Au-Ag), Savage
River (Fe) and Henty (Au) which combined are the most significant contributors to the GDP of the state.
Alpine Stellar was last reported on by the Company in December 20221. The recent review of Alpine Stellar
was undertaken as part of a re-evaluation of all advanced prospects held in the Company’s portfolio.
Stephen Swatton, President and CEO of CopperCorp commented:
“The work completed to establish an Exploration Target at Alpine Stellar reflects a strategic decision to re-
evaluate this prospect. The Company is currently evaluating options for infill and expansion drilling at
Alpine Stellar . The Company’s objective is to evaluate the potential to define a Mineral Resource in
accordance with NI 43-101 standards through further exploration. The Company now has two emerging
copper opportunities, Alpine and Jukes, the latter is currently being drilled and is located 10 km along strike
from the 300 Mt Mount Lyell copper mine.
Alpine Stellar is 60km north -west of Jukes and both locations already benefit from substantial technical
and infrastructure de-risking. The Alpine Stellar E xploration Target calculation is supported by 3 7 drill
holes, providing a strong foundation for advancing the project through targeted infill drilling. Beyond that,
deeper drilling has confirmed strong copper grades at the base of current drilling, highlighting the potential
to expand the system at depth.
Alpine Stellar also stands out for its location and infrastructural advantages, including sealed road access,
renewable power and water, in a low-altitude, mining-supportive jurisdiction. Its occurrence in the Arthur
Metamorphic Complex (AMC), now recognized as an overlooked and emerging Proterozoic IOCG belt ,
provides excellent district-scale exploration potential. The Exploration Target at Alpine Stellar offers a
compelling platform for growth as we look to recommence systematic advancement of this emerging
copper opportunity.”
Alpine Stellar Exploration Target
An ‘Exploration Target’ under the JORC Code (2012) is a statement or estimate of the exploration potential
of a mineral deposit in a defined geological setting where the statement or estimate, related to
Exploration Results, cannot be reported as a Mineral Resource.
The Exploration Target was defined using block model estimation based on wireframed >0.3% Cu
mineralized domains interpreted from drill hole data. The reported potential quantity and grade range
reflects grade–tonnage relationships evaluated at 0.3% and 0.45% Cu cut-off grades within the domains,
with the upper tonnage/lower grade case derived from the 0.3% cut -off and the lower tonnage/higher
grade case derived from the 0.45% cut-off.
The Exploration Target comprises a series of mineralized domains defined over approximately 600 metres
of strike length (Figure 1) . Mineralization has been intersected in drilling from near surface beneath
550-800 West Pender St. Vancouver, BC V6C 2V6 | E: [email protected] | W: coppercorpinc.com
shallow cover (locally 0 –40 metres depth) to approximately 440 metres below surface. Interpreted
domains extend up to 550 metres below surface, with individual domains varying in size and extent
depending on drill density and interpreted geological continuity. Drilling indicates that the system remains
open at depth and locally along strike.
The Exploration Target was established to provide an early-stage conceptual assessment of the potential
quantity and grade of the Alpine Stellar copper system, and to support internal evaluation of further
advancement of the project. It is an early-stage assessment that may help guide further exploration, but
it is not a M ineral Resource or Mineral Reserve and should not be treated as such. It has not been
evaluated for reasonable prospects of eventual economic extraction, and takes no account of geological
complexity, possible mining method or metallurgical recovery factors.
The Exploration Target is based on current geological understanding of the mineralization geometry,
subsurface geochemistry and project geology. This is provided by an exploration drill hole database
comprising 37 diamond core drill holes totalling 9,114m completed by CopperCorp and historical
operators across the Alpine Stellar prospect area.
Further details regarding the methodology used to define the Exploration Target are provided in the
“Technical Disclosure and Exploration Target Basis” section below.
Next Steps
The Company is evaluating follow -up drill program options to advance the Alpine Stellar Exploration
Target. Potential work includes infill and expansion drilling.
Within the current Exploration Target, high-grade (>1% Cu) zones have been intersected in multiple drill
holes, however, drill spacing remains wide in many parts of the system, limiting the current level of
geological confidence but highlighting an opportunity to expand high -grade domains through targeted
drilling.
The Company is currently assessing several additional target areas along strike within the broader Alpine
corridor, with ongoing geological mapping and soil sampling programs aimed at refining and prioritising
these opportunities within a 10 -20 kilometre radius of Alpine Stellar (Figure 1) . The Company looks
forward to providing further updates on these targets as work progresses.

Technical Disclosure and Exploration Target Basis
Information on previous exploration activities and results at the Alpine Prospect are included in the
Company’s Technical Report with an effective date of 18 April 2021 5, and previous CopperCorp TSX-V
News Releases1-4 as listed in the References section. No new exploration drilling results are reported in
this announcement.
The Exploration Target for the Alpine Stellar Zone was developed using mineralized domains constructed
in Surpac software, informed by drillhole geological logging and geochemical assay data. Domain
wireframes were interpreted on a sectional basis and constrained by geological understanding of the
mineralized system, with consideration given to continuity along strike and down dip.
Mineralized domains were defined for various case studies using copper grade thresholds of >0.1%, >0.3%
and >0.5% Cu. The Exploration Target is based on the >0.3% Cu domain, which was considered to provide
an appropriate and balanced representation of the mineralized system at the current stage of exploration.

Domain interpretation was guided primarily by grade continuity, supported by geological observations.
Minimum downhole widths of approximately 5 metres at >0.3% Cu and 3 metres at >0.5% Cu were
applied, with limited internal dilution incorporated to maintain geological continuity. Domain extents
were generally constrained to areas supported by drilling and extended down dip where geological
continuity was considered reasonable. Individual domains vary in extent depending on drill density and
geological confidence.
The Exploration Target is supported by data from 37 diamond drill holes totaling 9,114 metres, completed
by CopperCorp and historical operators. Drillhole assay data was composited to 2-meter intervals prior to
grade estimation, and bulk density values were assigned using measurements from the drill database.
Several interpolation methods, including Ordinary Kriging, Inverse Distance Weighting and Nearest
Neighbour estimation, were evaluated. Nearest Neighbour estimation was selected for the Exploration
Target as it was considered to best preserve grade distribution between drillholes and provide geologically
reasonable results at the current level of drill spacing.
Grade–tonnage curves generated from the block model were used to evaluate the range of potential
tonnes and grades across a range of copper cut -off grades. The reported potential quantity and grade
range of the Exploration Target reflects grade–tonnage relationships evaluated at 0.3% and 0.45% copper
cut-off grade scenarios, with the upper tonnage/lower grade case derived from the 0.3% cut-off and the
lower tonnage/higher grade case derived from the 0.45% cut-off. The Exploration Target range reported
reflects the uncertainty inherent in the current level of drilling and sensitivity to copper cut-off grades.
The potential quantity and grade of the Exploration Target on the Alpine Stellar Zone are conceptual in
nature. There has been insufficient exploration to estimate a Mineral Resource, as defined by National
Instrument 43-101 Standards of Disclosure for Mineral Project (“NI 43- 101”), and it is uncertain if further
exploration will result in the target being delineated as a Mineral Resource.
About the Alpine Prospect
The Alpine prospect was discovered by CRA Exploration in the early 1980’s after following up an airborne
magnetic survey with gridding, ground magnetics, and soil geochemistry followed by two diamond drill
holes in 1985. Stellar Resources drilled a further 19 holes between 2006 and 200 8. The historical, wide-
spaced drilling intersected significant IOCG style copper mineralization. CopperCorp gained ownership of
the prospect in 2019 and between 2020 -2022 drilled a further 16 holes for 5,4 90m in the Alpine Stellar
zone.
IOCG style m ineralization at Alpine is hosted in intensely deformed and metamorphosed amphibolites,
mafic and pelitic schists, graphitic phyllites and carbonates belonging to the Bowry Formation of the
Arthur Metamorphic Complex. Copper mineralization is associated with multiple sub-parallel magnetite-
hematite-siderite-sulphide lenses in strongly silica-siderite altered chlorite schists. Mineralization consists
mainly of chalcopyrite with lesser covellite and bornite. Additional chalcopyrite -pyrite breccia, vein and
disseminated mineralization is hosted in silica-siderite altered and veined quartzites and schists adjacent
to the ironstone lenses.

Mineralization remains open at depth, providing an opportunity for deeper drilling to test for extensions
of the system below the current limits of drilling. Strong copper intercepts near the base of the current
drill footprint, include1:
• AP034: 5.0m @ 2.06% Cu from 187.0m, within 31.6m @ 0.64% Cu from 177.7m
• AP035: 18.0m @ 0.90% Cu from 238m, within 45.0m @ 0.62% Cu from 217.0m
• AP036: 23.0m @ 1.14% Cu from 393m, within 92.0m @ 0.50% Cu from 334.0m
Geological interpretation indicates that the host structural and stratigraphic framework at Alpine has the
potential for repetition of favourable host sequences related to folding and structural offsets. This
provides scope for the identification of additional mineralized zones in close proximity to the current
Exploration Target.
The Alpine Stellar prospect benefits from excellent infrastructure access, including sealed roads, grid
power and water, and is located at low altitude in a stable regulatory environment. These attributes
provide a strong foundation for efficient exploration and support the potential for accelerated
development pathways.
