CopperCorp Intersects High-Grade Cu-Au Mineralization at Jukes ProspectVancouver, British Columbia--(Newsfile Corp. - December 18, 2025) - CopperCorp Resources Inc. (TSXV: CPER) (OTCQB: CPCPF) ("CopperCorp" or the "Company") is pleased to announce first assay results from its Phase 2 drilling1,2 campaign at the Jukes Cu-Au prospect in western Tasmania, Australia.Example of core showing high-grade chalcopyrite-pyrite-chalcocite mineralization, JDD004, 93.0m (1.0m @ 6.95% Cu, 0.53g/t Au, 23.4g/t Ag (7.48% CuEq) from 92.6m).To view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/8950/278491_da0f5e7524a54ae4_002full.jpgHighlightsInitial Phase 2 drilling results confirm the northern extension of high-grade Cu-Au-Ag mineralization at Jukes, with new drillholes intersecting mineralization approximately 300 m along strike from CopperCorp's previous drilling. Key drill intercepts include:JDD003:9.0m @ 0.81% Cu, 0.21g/t Au, 6.2g/t Ag (1.0% CuEq) from 167.0m, including2.0m @ 2.0% Cu, 0.56g/t Au, 15.8g/t Ag (2.5% CuEq) from 169JDD004:5.2m @ 1.32% Cu, 0.12g/t Au, 7.42g/t Ag (1.46% CuEq) from 70.0m, including3.4m @ 1.75% Cu, 0.17g/t Au, 9.33g/t Ag (1.93% CuEq) from 71.8m1.0m @ 6.95% Cu, 0.53g/t Au, 23.4g/t Ag (7.48% CuEq) from 92.6m12.6m @ 0.78% Cu, 0.15g/t Au, 3.43g/t Ag (0.91% CuEq) from 109.9m, including:1.1m @ 2.05% Cu, 0.72g/t Au, 9.55g/t Ag (2.62% CuEq) from 109.9m; and1.0m @ 5.75% Cu, 0.52g/t Au, 17.25g/t Ag (6.23% CuEq) from 121.510.0m @ 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 2.0m @ 1.39% Cu, 1.11g/t Au, 10.07g/t Ag (2.24% CuEq) from 212.0mHigh-grade Cu-Au-Ag mineralization is also confirmed at surface, with channel sampling returning:5.0m @ 3.62% Cu, 0.62g/t Au, 32.6g/t Ag (4.28% CuEq), including1.0m @ 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 UpdateInitial 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.JDD003JDD003 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 JDD002W13. 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.JDD004JDD004 was drilled to test for strike extensions of s
