Neighbouring the Paterson Project in the Eastern Pilbara region of Western Australia, the Company’s Oakover Project comprises eight granted exploration licences held 100% by the Company.
The Oakover Project is centred on the Oakover Basin, which is recognised as having the main elements of a significant base metal and manganese mineral province, including by previous explorers such as BHP and CRA Exploration. It is a large sedimentary basin, formed during extensional tectonic events above a metal-rich, predominantly mafic volcanic basement. These periods of extension and subsequent compression have provided opportunities throughout the Basin for focussed fluid flow within fault zones and along stratigraphic units through reactive host sequences, enabling mineralisation to occur in a variety of settings.
The Company’s tenement holding in the western Oakover is considered prospective for copper and “Balfour” style manganese deposits (med-grade Mn/Fe), including the Western Star copper prospect and historic Davis River manganese occurrences. Along the eastern edge of the Oakover Basin the tenement holding includes sediment-hosted copper occurrences at Bocrabee, and numerous high-grade “Woodie-Woodie” style manganese prospects (typical Mn >45%, Fe<5%) in the Fig Tree area (30km south of Consolidated Minerals’ Woodie Woodie mine).
Oakover and Paterson Project tenement location plan
The Oakover Basin is host to the world class Woodie Woodie Manganese mine, which has been a source of high grade manganese since the 1960s; as well as a number of other smaller producing mines (Nicholas Downs, Skull Springs, Davis River, Ant Hill). Manganese deposits occur as stratabound deposits, typically as lower grade mineralisation in Manganese Group shales and Pinjian Chert Breccia, or as high grade hydrothermal carbonate replacement mineralisation in the Carawine Dolomite. The Company has numerous early to advanced manganese prospects within the Project.
The same processes for manganese deposits are invoked to explain a number of hydrothermal, very high grade haematite iron deposits in the region (e.g. Blue Valley on E46/1069), with the predominance of iron over manganese interpreted to be a function of fluid chemistry and wall rock reactivity.
