Operating copper mine, 16km West of Cloncurry. Formally known as the Rocklands Group Copper Project.

Rocklands mineralisation is dominated by dilational brecciated shear zones, throughout varying rock types, hosting coarse splashy to massive primary mineralisation, high-grade supergene chalcocite enrichment and bonanza-grade coarse native copper. Structures hosting mineralisation are sub-parallel, east-south-east striking, and dip steeply within metamorphosed volcano-sedimentary rocks of the eastern fold belt of the Mt Isa Inlier. The observed mineralisation, and alteration, exhibit affinities with Iron Oxide-Copper-Gold (IOCG) deposits. Polymetallic copper-cobalt-gold mineralisation, and significant magnetite, persists from the surface, through the oxidation profile, and remains open at depth.

Between August and October 2017 a two-month mineral specimen recovery operation for exceptional native copper specimens was carried out in conjunction with UK Mining Ventures Ltd.
