o 10.0m @ 0.73% Cu, 0.43g/t Au, 4.11g/t Ag (1.06% CuEq) from 204m, including:
1.0m @ 2.5% Cu, 0.56g/t Au, 9.64g/t Ag (2.96% CuEq) from 206.0m
550-800 West Pender St. Vancouver, BC V6C 2V6 | E: [email protected] | W: coppercorpinc.com
2.0m @ 1.39% Cu, 1.11g/t Au, 10.07g/t Ag (2.24% CuEq) from 212.0m
• High-grade Cu-Au-Ag mineralization is also confirmed at surface, with channel sampling returning:
o 5.0m @ 3.62% Cu, 0.62g/t Au, 32.6g/t Ag (4.28% CuEq), including
1.0m @ 7.5% Cu, 2.18g/t Au, 46.7g/t Ag (9.35% CuEq)
• Mineralization remains open in all directions, with further strike and depth extensions supported
by strong IP chargeability corridors and anomalous surface geochemistry.
Stephen Swatton, President and CEO of CopperCorp, commented
“I am extremely encouraged with the progress at Jukes ; these latest results continue to improve our
understanding of the style and scale of mineralization. Importantly, drilling has now confirmed that high-
grade Cu-Au-Ag mineralization occurs repeatedly over significant strike lengths and to significant depths,
consistent with our evolving interpretation of a structurally controlled system, with steeply oriented high-
grade shoots and veins developed in a broader mineralized enveloped. This style of mineralization shares
important characteristics with the nearby 3 million tonne Cu / 3 million ounce Mt Lyell copper-gold mining
camp which hosts 22 distinct orebodies, most of which are oriented in vertical pipe-like structures.
Drilling at Jukes remains widely spaced, with only a small portion of the extensive target area tested to
date. The repetition of high-grade mineralization within this limited drill density is particularly encouraging
and highlights the potential for additional high- grade zones to be identified with ongoing systematic
drilling.
As results continue to come in from Jukes, we will continue to refine our understanding of the system and
assess optimal drill spacing to work towards the design of a NI 43 -101-compliant mineral resource. The
discovery of a high-grade, mid-sized copper-gold deposit at this location would be welcomed by both the
local mining community and the Tasmanian government which has indicated a strong desire to see mining
revenues continue to underpin the State’s economy.”
Jukes Phase 2 Drilling Update
Initial assays have been received for the first 2 holes (JDD003 and JDD004) of the Jukes Phase 2 diamond
drilling program. Significant intercepts are shown in Table 1, see also Figures 3 and 4. The objective of the
Phase 2 drill program is to test extensions of mineralization intersected in CopperCorp’s 2024 Phase 1
drilling3,4.
As of reporting, the Company has now completed 4 diamond drill holes at Jukes that have tested
approximately 300m of strike and to depths over 500m from surface. All holes completed by CopperCorp
at Jukes so far have successfully intersected zones of high-grade copper-gold-silver mineralization.
Drilling remains in progress on holes JDD005 and JDD006 with two rigs currently onsite.
Full results have been received for hole JDD003 while only partial (0 -240m) results are available for hole
JDD004.
JDD003
JDD003 was drilled to test for mineralization associated with the western IP chargeability zone below the
historical King Jukes No.1 mine adit and 300m north along strike from Phase 1 hole JDD002W1 3. JDD003
successfully intercepted disseminated, vein and stringer chalcopyrite -pyrite mineralization from 150m
down hole with the mineralization then faulted out at 177.2m. Mineralized intercepts are listed in Table
1.
JDD004
JDD004 was drilled to test for strike extensions of structurally controlled mineralization observed
outcropping along the Mt Jukes paved road. Results for channel sampl ing of the outcropping
mineralization by CopperCorp are summarized below (Table 2). JDD004 successfully intercepted multiple
zones of structurally controlled high -grade copper-gold-silver mineralization (see significant mineralized

intercepts in Table 1). Copper mineralization in JDD004 comprises stringer- vein to breccia-fill and semi-
massive style chalcopyrite -pyrite-magnetite, with bornite, cuprite and malachite also noted in some
zones.

Jukes Prospect Overview
The Jukes prospect 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-Ag system with hybrid porphyry-
IOCG style mineralization developed within the same volcanic host rock package and in a similar structural
setting to the Mt Lyell system.
550-800 West Pender St. Vancouver, BC V6C 2V6 | E: [email protected] | W: coppercorpinc.com
The prospect is characterized by strong, coincident 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 300 m
and from near surface to depths exceeding 500 m vertically. Importantly, mineralization remains open in
all directions, drilling remains widely spaced, and large portions of the interpreted geophysical footprint
remain untested.
Prior to the Phase 2 drilling campaign, exploration drilling — including CopperCorp’s successful 2024
Phase 1 program — had tested only the southern margin of this extensive target area. Drilling intersected
multiple zones of Cu -Au-Ag mineraliz ation, including broad mineraliz ed envelopes containing discrete
high-grade structural intervals (see Tables 3, 4, 5 and 6) . These results provided strong validation of the
exploration model and formed the basis for the expanded Phase 2 program now underway. Significant

Exploration Significance of High-Grade Structural Mineralization
Drilling and sampling completed to date at the Jukes prospect consistently demonstrates that the system
is mineraliz ed and capable of generating high- grade copper -gold-silver mineralization. Every drillhole
completed by CopperCorp at Jukes to date has intersected Cu-Au-Ag mineralization, a highly encouraging
outcome given the very limited amount of drilling completed across a large target area.
The combined drilling and channel sampling results indicate that favourable structural conditions capable
of focusing higher -grade mineraliz ation are developed at multiple positions within the broader Jukes
system. In all holes drilled to date, higher- grade mineraliz ation occurs within discrete, structurally
controlled zones over-printing broader envelopes of alteration and disseminated sulphides — a pattern
typical of large hydrothermal Cu-Au systems where structures act as conduits for mineralizing fluids.
High-grade structurally-controlled mineralization has now been intersected over several hundred meters
of strike length and is closely associated with strong IP chargeability anomalies. This spatial relationship
provides confidence that the extensive IP-defined corridors at Jukes are directly linked to mineralization
and represent high-priority targets for ongoing drilling. The potential repetition of high-grade zones over
this distance significantly upgrades the exploration potential of the Jukes system at this early stage.
Next Steps
Phase 2 drilling at the Jukes prospect will continue into 2026, with ongoing work focused on systematically
testing the extensive IP-defined chargeability corridors now interpreted across the prospect. Drilling will
prioritize step-outs along strike and at depth from existing mineraliz ed intercepts, as well as structural
intersections and chargeability highs considered prospective for the development of additional high-grade
mineralized zones.
With only four drillholes completed by CopperCorp to date across a large and well- defined geophysical
footprint, the majority of the Jukes system remains untested. Results from ongoing drilling will be used to
further refine geological and structural targeting as the Company continues to evaluate the scale and
continuity of mineralization at the prospect.
In parallel, exploration activities are also advancing at the Hydes and Linda target areas, and the Company
looks forward to providing further updates as work progresses.

Table 8. Significant mineralized intervals, channel sampling - Jukes prospect underground workings
(historical sampling - previously reported5 but without CuEq calculations). Reported grades are calculated
as along-channel length weighted averages. Intercepts are along-channel intervals.
*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 exploit ed 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 exploration comparison purposes only and should not be
interpreted as an estimate of economic value.

Hydes
The drilling at Hydes is incomplete with the target horizon untested due to drilling complications. The
company is currently mobilizing a field crew to undertake more sampling and mapping at surface with a
view to possibly continuing the drill program supported by helicopter in Q1/2 2026.
