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.
These results further confirm the Company's interpretation from historic drilling of multiple continuous zones of copper mineralization at
the Stellar Zone
over a strike length of
700m
(open) and to a vertical depth of
300m
(open).
The Stellar Zone forms part of the larger Alpine Prospect target at the southern end of the Company's 1,066 km
2
AMC Project.
Copper mineralization at the Stellar Zone is interpreted to be Iron-Oxide-Copper-Gold (IOCG) in style and occurs within a strong,
regional, north-south striking magnetic zone associated with the Arthur Metamorphic Complex that continues over 100 km of strike
length within the AMC Project.
Additional high-priority exploration drill targets, Alpine West and Alpine North, have been identified at the Alpine Prospect through
surface sampling and geophysical surveys. These new targets cover an area of approximately 1km by
300m
at Alpine North and 800
by
300m
at Alpine West (Figure 2). The Company is particularly encouraged by the discovery potential of these additional targets due
to interpreted similarities with the geochemical and geophysical expressions over the drilled copper mineralization at the Stellar Zone.
The Company's ongoing drilling program is focused on step-out drilling to depth and along strike at the Stellar Zone, and will also
begin sequential drill testing of additional targets at the Alpine Prospect.
Assays from a further seven drill holes from the initial Stellar Zone drilling are pending. There has been significant delay in processing
times at the laboratory and the additional seven holes will be reported shortly after they are received.
Stephen Swatton
, President and CEO of CopperCorp, stated, "The Company is very encouraged by these first drill assay results
received from the Stellar Zone at Alpine which is the first exploration drilling to be conducted in the area in 14 years. The results are
consistent with the historical drilling and, importantly, confirm continuity of mineralization between historical holes.
Mineralization at the
Stellar Zone is open along strike and at depth and results from recent
geophysical and surface geochemical work has confirmed
potential for a large-scale Iron-Oxide-Copper-Gold (IOCG) system at Alpine which the Company plans to continue testing as recently
announced with the Alpine Phase 1 drilling program being expanded to
10,000m
. The results further highlight the prospectivity of the
Arthur Metamorphic Complex for IOCG style mineralization over which the Company has a dominant land holding.
"
Alpine Prospect Drilling
At the time of reporting, the Company has completed drilling of 11 diamond core holes for a total of
3,925m
at the Alpine Stellar Zone,
with a 12
th
hole in progress. The drill program comprises confirmation and infill holes designed to confirm historical copper grades, test
continuity of mineralization, and provide geological and structural context to the mineralization.
Assay results from the first 4 drill holes have been received. All 4 holes intersected broad zones of copper mineralization and significant
mineralized drill hole intercepts are listed in Table 3. The overall grade and width of the mineralized intercepts are consistent with historical
intersections (Table 4) and provide support for the continuity of mineralization between historical drill holes.
Drilling to date has intersected up to three zones of mineralization at the Stellar Zone and has confirmed a steep southeast to east dipping
trend of the mineralization.

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 2008. The historical, wide-spaced drilling intersected significant IOCG-style copper mineralization, with significant intercepts
including (See Table 4):
AP004:
38.2m
@ 0.79% Cu from
57.7m
, including
28.2m @ 1.03 % Cu from 58.7m and 41.8m @ 0.3% Cu from 111.0m
AP007: 86.0m @ 0.50% Cu from 62.0m
AP008A:
41.0m
@ 0.48% Cu from
29.8m
AP017:
24.7m
@ 0.52% Cu from
222.0m
Mineralization 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 up to three
sub-parallel magnetite-hematite-sulphide lenses in strongly silica-siderite altered chlorite schists (see examples in Figures 7 and 8).
Mineralization consists mainly of chalcopyrite with lesser covellite and bornite. Additional chalcopyrite-pyrite breccia mineralization is
hosted in silica-siderite altered and veined quartzites and schists adjacent to the ironstone lenses. Anomalous levels of cobalt is associated
with the copper mineralization, typically averaging 200 to 300ppm Co and locally reaching up to 0.1% Co over short intervals.
The mineralization strikes east-northeast and dips steeply to the southeast, forming an interpreted fault-bound boudinage within the highly
deformed schists of over
600m
in strike length. Drilling completed to date indicates that the thickest part of the Stellar mineralized zone is
over
100m
in width, thinning to the west and thickening towards an interpreted faulted fold hinge in the east. The deposit remains open
down dip and along strike to the west.
As previously reported
1
, results from recent geophysical modelling indicate that the drilled IOCG style mineralization at the Alpine Stellar
Zone is defined by coincident gravity and magnetic anomalies (see Figure 1). The model further indicates additional areas of high IOCG
prospectivity indicated by coincident, partially coincident, or offset gravity and magnetic anomalies – the Alpine West and Alpine North
targets (Figures 2 & 3) which the Company plans to drill test.
Next Steps
The drilling program at the Stellar Zone is ongoing with assays from a further 7 drill holes awaited. As previously announced
1
, the
Company plans to expand the diamond drilling program from
4,200m
to
10,000m
. The expanded drill program will be focused on vectoring
towards potential zones of thicker and higher-grade mineralization in the Stellar Zone, testing the Stellar Zone at depth, and step-out
drilling to test high-priority targets at Alpine West and Alpine North. Planning and permitting for the Alpine West and Alpine North
exploration drill programs is underway. The Company currently has one drill at Alpine and plans to source another to expedite the planned
drilling. Further infill and extension gridding and soil sampling programs are also planned.

Quality Assurance / Quality Control on Assay Results
Full information on historical exploration activities and results at the Alpine Prospect and AMC Project are included in the Technical Report
(NI 43-101) dated
18 April 2021
2
.
CopperCorp's diamond core drill holes are drilled at HQ and NQ core diameters using triple tube to maximize recovery. Core recovery is
generally good in mineralized zones (95-100%) with poorer recoveries associated with brittle faulting on zone margins. Sample collection is
supervised by CopperCorp geological staff. Mineralized zones are marked up for sampling by an experienced geologist. Half core is split
by diamond saw on nominal
1.0m
sample lengths while respecting geological contacts. Samples are bagged and ticketed prior to delivery
by Company personnel to the ALS commercial laboratories in Burnie,
Tasmania
, for sample preparation. The half core samples are
crushed to 80% passing 2mm, riffle split to 500g and then pulverized to pass 75um. Coarse duplicate sampling is conducted every 20
samples to assess variability of the coarse crush. Cu and multi-element assay is by 4-acid digest followed by ICP-MS at ALS laboratories
by method ME-ICP61a). Au assay is by 30g fire assay at ALS laboratories by method Au-AA25. Certified reference materials (CRMs),
blank and duplicate QAQC samples are included in sample submissions at 20 sample intervals. All QAQC samples were within acceptable
limits (2 standard deviations for CRMs, duplicates <5%).
Mineralized Interval Calculations
Reported significant mineralized intervals in this news release (including for new and historical drillhole intervals) are calculated as down-
hole length-weighted intercepts using a 0.1% Cu lower cut-off grade and carry a maximum internal dilution of
4m
(except for AP012A
which has a maximum internal dilution of
7m
). The calculated intervals for historical drill holes may vary from previously reported interval
calculations that used a cut-off grade of 0.3% Cu. The 0.1% Cu cut-off grade is considered to appropriately define the boundaries of
mineralized zones and provides for more balanced reporting of drilling results during the exploration stage, enabling reporting of both low-
and high-grade intercepts. For consistency, drill hole intercepts from all historical drill holes using the 0.1% Cu cut-off are also displayed in
Table 4. No top-cut grade was applied. True widths of drill hole intercepts are yet to be determined.
