CopperCorp Delivers Additional High-Grade Copper
Intercepts at Jukes, including 13m @ 2.01% CuEq
VANCOUVER, BC March 10th, 2026 – CopperCorp Resources Inc. (TSXV: CPER ; OTCQB: CPCPF)
(“CopperCorp” or the “Company”) is pleased to provide an exploration update from Jukes, the Company’s
100% owned Cu-Au prospect in western Tasmania, Australia, where the Phase 2 drilling program has
intersected both broad zones of near-surface mineralization and deeper, higher-grade copper-gold-silver
intersections.
Highlights
• JDD007 intersected a broad zone of near-surface mineralization including:
o 36.0m @ 0.54% Cu, 0.13g/t Au, 1.84g/t Ag (0.64% CuEq) from 66m, including
12.0m @ 0.77% Cu, 0.20g/t Au, 1.18g/t Ag (0.92% CuEq) from 69.0m, and
4.0m @ 0.98% Cu, 0.17g/t Au, 5.1g/t Ag (1.13% CuEq) from 89.0m
• At depth JDD007 intersected multiple high-grade structural Cu-Au lodes including:
o 13.0m @ 1.18% Cu, 1.14g/t Au, 3.93g/t Ag (2.01% CuEq) from 205.0m, including
1.0m @ 6.28% Cu, 12.2g/t Au, 9.27g/t Ag (14.91% CuEq) from 206.0m, and
1.15m @ 5.34% Cu, 1.72g/t Au, 24.80g/t Ag (6.72% Cu Eq) from 213.85m
• The broad zone successfully extends fault -bound chalcopyrite copper minerali zation beneath
historical adit workings and remains open along strike. Drilling is underway to test the down-dip
extension of this near-surface mineralization.
• High-grade mineralization at depth is associated with semi-massive chalcopyrite breccia veins and
supports an emerging high-grade lode model at Jukes.
• An additional drill site located 100m west of JDD007 is being established. The new drill site will
enable step out drilling along strike to the west to further test the shallower, broad zone of
chalcopyrite mineralization.
• Multiple high-grade copper–gold zones are identified within the broader hydrothermal system at
Jukes. Drilling to date has confirmed Cu-Au-Ag mineralization over a drilled strike length of at least
350 m and from near surface to depths exceeding 500 m vertically. Importantly, large portions of
the Jukes system remain untested.

Stephen Swatton, President and CEO of CopperCorp, commented:
“This year’s drill program (Phase 2) at Jukes has delivered strong results: Phase 1 and Phase 2 drilling have
both confirmed that high grade copper–gold-silver mineralization remains open both along-strike and at
depth. Accordingly, we are re -opening historical road tracks to access new drill sites west of where
CopperCorp has drilled to date , this will enable us to test unexplained IP geophysical targets . It appears
that the mineralization east of JDD001 and JD D007 is largely faulted out so the potential for further
continuous copper-gold grade is anticipated to be located to the west and north.
These results are highly encouraging for Jukes and for the broader portfolio of prospects that we are
advancing adjacent and along trend from Mount Lyell, including Linda, Hydes, Sumpters, and Marigold.
These are just a few of the many targets within the 25 km- long prospective belt that is 100%- owned
by CopperCorp.
Our neighbour, Sibanye-Stillwater, recently released an updated mineral reserve estimate and feasibility
study for the Mount Lyell deposit1, located along strike from Jukes Prospect. The updated mineral estimate
for the Mount Lyell deposit includes proved and probable reserves of 54.6 Mt at 0.88% Cu and 0.2 g/t Au
(approximately 478,000 tonnes of in -situ copper and 350,000 ounces of in -situ gold). The Mount Lyell
feasibility study envisages a 3 Mtpa operation with an initial 23 -year mine life, producing approximately
26,000 tonnes of copper and 16,000 ounces of gold in concentrate annually.”
Jukes Phase 2 Drilling Update
CopperCorp has now completed 7 diamond drill holes totaling 2,82 9m at Jukes that have tested
approximately 350m of strike -length to depths of up to 500m below surface (Figure 1) . Assays have
recently been received for 3 holes (JDD005, JDD006, and JDD007) with significant intercepts shown in
Table 1.
JDD007 tested beneath the historical Jukes No.3 Main Adit workings along strike from Phase 1 drill hole
JDD0016,2. JDD007 successfully intersected a broad zone of copper -gold mineralization from 66m
associated with chalcopyrite mineralization in chlorite-siderite alteration adjacent to the bounding Jukes
Fault. Additionally, a zone of h igh-grade gold-copper mineralization was intersected from 205m, hosted
within structurally controlled semi -massive chalcopyrite-siderite breccia veins. Photos of both styles of
mineralization are shown in Figure 2.
These latest drill results from JDD007 continue to demonstrate that favourable structural conditions
capable of focusing higher -grade mineralization are developed at multiple positions within the broader
Jukes system. In most holes drilled to date, high -grade lode-style mineralization occurs within discrete,
structurally controlled zones within broader envelopes of alteration and disseminated sulphides . The
potential for multiple depth-extensive high-grade lodes at Jukes is considered a highly encouraging sign
this early in the exploration process.

*Copper Equivalent Calculations
Copper equivalent (CuEq) values used throughout this announcement have been calculated using the
formula CuEq (%) = Cu(%) + Au(g/t) x 0.702 + Ag(g/t) x 0.00695, based on metal prices of US$4.20/lb
copper, US$2,600/oz gold and US$30/oz silver. Metallurgical recoveries of 90% for copper, 70% for gold
and 60% for silver have been assumed. Recovery assumptions are based on historical metallurgical
performance from the nearby Mt Lyell copper –gold mining operations, which exploited mineralization of
similar style and broadly comparable mineralogy to that observed at the Jukes prospect. No metallurgical
test work has been completed on mineralization from the Jukes prospect, and actual recoveries may differ
from those assumed.
Copper equivalent values are expressed as percentages and are calculated by converting gold and silver
grades to copper equivalent using the stated metal prices and recoveries and summing these with the
copper grade. CuEq values are provided for exploratio n comparison purposes only and should not be
interpreted as an estimate of economic value.
Jukes Prospect Overview
The Jukes prospect represents the most advanced copper-gold target within CopperCorp’s 100% owned
Razorback property and is located approximately 10 km south of the Sibanye -Stillwater owned Mt Lyell
copper-gold mining camp (historical production of ~3 Mt contained copper and ~3 Moz contained gold).
Jukes is interpreted to host a large, structurally controlled hydrothermal Cu -Au system with IOCG style
affinities developed within the same volcanic host rock package and in a similar structural setting to the
Mt Lyell system.
The prospect is characterized by strong, coherent IP chargeability, magnetic, and geochemical anomalies
that define a prospective footprint of at least 700 m in strike length (open) and approximately 400 m in
width. Drilling to date has confirmed Cu-Au-Ag mineralization over a drilled strike length of at least 350 m
and from near surface to depths exceeding 500 m vertically. Importantly, mineralization remains open in
all directions, and large portions of the interpreted geophysical footprint remain untested.
Drilling and sampling completed to date at the Jukes prospect consistently demonstrates that the system
is mineralized and capable of generating high-grade copper-gold mineralization. Every drillhole completed
by CopperCorp at Jukes to date has intersected Cu -Au-Ag mineralization, a highly encouraging outcome
given the limited amount of drilling completed across a large target area.
Next Steps
Phase 2 drilling at the Jukes prospect will continue into 2026 and drilling of JDD008 has commenced.
Drilling will prioritise step-outs along strike and at depth from existing high-grade mineralised intercepts.
In parallel, exploration activities are also advancing at the Marigold, Hydes and Linda target areas at
Razorback, and the Company looks forward to providing further updates as work progresses at both this
prospect and encouraging grassroots exploration on the AMC Project.

Sampling, QAQC and Analytical Procedures
The Jukes diamond core drill holes are drilled at HQ and NQ core diameters using triple tube to maximize
recovery. Core recovery was generally good in mineralized zones (95 -100%). Sample collection was
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 3.1mm, rotary split to 750g and then pulverized to pass 75um. Duplicate sampling is
conducted every 20 samples to assess variability of the assay pulp. Cu and multi -element assay is by 4 -
acid digest followed by ICP -MS at ALS laboratories by method ME -ICP61r. Over-range (high-grade) Cu
samples are further assayed by method Cu -OG62. 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%).

resampling and analysis of accessible historical exploration adits in order to independently verify historical
results.
Mineralized Interval Calculations
Reported Cu-Au-Ag significant mineralized intervals in this news release are calculated as down -hole or
along-channel length-weighted intercepts using lower cut -off grades of 0.1% Cu for low -grade bulk
intervals, and 0.3% Cu for higher-grade intervals. A maximum internal dilution of 5m and 2m is generally
allowed for in the low -grade and high -grade intervals respectively (noting that the JDD006 broad 66m
low-grade interval allowed for up to 11m of internal dilution). No top-cut grade was applied. Drilling data
to date is insufficient to determine true width of mineralization.
Copper Equivalent Calculations
Copper equivalent (CuEq) values used throughout this announcement have been calculated using the
formula CuEq (%) = Cu(%) + Au(g/t) x 0.702 + Ag(g/t) x 0.00695, based on metal prices of US$4.20/lb
copper, US$2,600/oz gold and US$30/oz silver. Metallurgical recoveries of 90% for copper, 70% for gold
and 60% for silver have been assumed.
Recovery assumptions are based on historical metallurgical performance from the nearby Mt Lyell
copper–gold mining operations, which exploited mineralization of similar style and broadly comparable
mineralogy to that observed at the Jukes prospect. No meta llurgical test work has been completed on
mineralization from the Jukes prospect, and actual recoveries may differ from those assumed.
Copper equivalent values are expressed as percentages and are calculated by converting gold and silver
grades to copper equivalent using the stated metal prices and recoveries and summing these with the
copper grade. CuEq values are provided for exploratio n comparison purposes only and should not be
interpreted as an estimate of economic value.
