Panorama

Geology of the area is predominantly greenstone and granite of the Archean Pilbara Craton in northern Western Australia, and younger overlying sedimentary and volcanic sequences.

Government geological mapping confirms the presence of coarse-grained Archean sedimentary rocks striking over 18km from north to south throughout the Panorama project area.

Historically, the Pilbara Region is recognised for its gold and base metal mineralisation. However, aside from the work by Anglo American in the early 1970s, very little subsequent exploration work has been carried out within the Panorama project area, leaving the cobalt mineralisation untested.

The large area of the cobalt in-streams anomaly suggests a significant mineralising event has occurred. The definitive source of the cobalt is not yet known, however it is likely to be localised in folding and faulting of the bedrock sequences similar to other known styles of mineralisation in Archean greenstones elsewhere in the Pilbara which display drill intercepts with high cobalt of up to 0.99%.

The Mount Roe Basalt sits at the base of the Fortescue Group stratigraphy that is widespread throughout the Pilbara region of Western Australia. There is considerable geological discussion as to the origin of palaeo-placer gold in the Pilbara. It is known to occur in the Hardy Formation Conglomerate immediately overlying the Mount Roe basalt and it is also known to occur in a stratigraphically lower conglomerate horizon occurring at the base of the Mt Roe Basalt. These palaeo-placer deposits are different to gold associated with other styles of mineralisation such as lode or epithermal types.
