KEY HIGHLIGHTS
- Final Jukes Drill Results: Concluding the Company’s exploration program at the Skyline property, CopperCorp reports final core assay results from diamond drill hole JDD008 at the Jukes prospect, which intersected 12.0 m @ 0.54% Cu, 0.14 g/t Au, and 0.89 g/t Ag from 92.0 m downhole (including 3.0 m @ 0.85% Cu, 0.16 g/t Au, and 1.05 g/t Ag).
- A$100,000 EDGI Grant Awarded: CopperCorp has been awarded a A$100,000 co-funding grant under Round 12 of the Tasmanian Government’s Exploration Drilling Grant Initiative (“EDGI”), administered by Mineral Resources Tasmania, providing up to 50% co-funding of eligible direct drilling costs.
- Skyline Property Sale Summary: Further to the binding agreement announced October 26, 20261, CopperCorp has, subject to the formal transaction closing with ASX listed Bubalus Resources Limited, divested the Skyline property (the “Transaction”). The completion of the Transaction will deliver non-dilutive balance sheet strength to focus on the flagship AMC Project (556 km²) and Jasper Hills Project (70 km²).
Beyond the Headline
CopperCorp is exploring a nearly 2,000km² 100% owned land package covering two underexplored geological trends with more than 20 mid to advanced stage copper-gold prospects in Western Tasmania, Australia. Mining is the largest contributor to Tasmania’s GDP and mercantile export earnings. 90% of northwest Tasmania’s economy relies on mining and mining related activities.
This press release reports final results from the eight (8) diamond drill holes completed in the Phase 2 program at the Company’s Jukes Cu-Au prospect on its Skyline property. Drilling has tested approximately 350 m of strike length and reached depths of up to 500 m below surface. The results confirm a significant Cu-Au mineralizing system characterized by broad, relatively low-grade envelopes containing narrower high-grade Cu-Au zones.
The following table summarizes the most important reported intersections from this program. The best intersection in the program was Hole JDD007 which returned 13.0m @ 1.18% Cu, 1.14 g/t Au & 2.01 g/t Ag.

The drilling indicated two main styles mineralization:
- Broad disseminated Cu-Au envelopes, typically around 0.15–0.5% Cu, with locally better grades.
- Structurally controlled higher-grade lodes, locally exceeding 1–2% Cu, with significant gold credits.
The high-grade zones are associated with chalcopyrite-bearing breccias and veins, commonly accompanied by chlorite, siderite and magnetite alteration. The Jukes Fault appears important in controlling mineralization. CopperCorp has indicated that mineralization east of JDD001 and JDD007 may be faulted out, with better exploration potential to the west and north.
On October 26, 2026, CopperCorp announced the sale of the Skyline Property which includes the Jukes prospect to ASX listed Bubalus Resources Limited. The completion of the Transaction will deliver non-dilutive balance sheet strength to focus on the flagship AMC (556 km²) and Jasper Hills (70 km²) Projects.
Comments
The drill results at Jukes indicate widespread but generally low grade Cu-Au mineralization. Sale of the project is a good strategic move as it will allow the Company to focus on its priority assets.
