Mount Thirsty

Project Overview

Laterite cobalt-nickel

Mount Thirsty is Australia’s most advanced genuine cobalt project with a Pre-Feasibility Study (PFS) completed in 2020.​ The Mount Thirsty Project is located 16km northwest of Norseman, Western Australia and is a 50/50 Joint Venture between Barra Resources Ltd and Conico Ltd. The Project is close to all necessary infrastructure (rail, road, power, gas, water, townsite, fibre optic and seaport) and in a mining orientated state

Mount Thirsty: Geology

The Mt Thirsty Cobalt Deposit is hosted in a strongly weathered ultramafic peridotite rock located between a sediment-ultramafic-basalt sequence to the west and a thick gabbro-pyroxenite unit to the east. Weathering and supergene enrichment processes have produced the deposit which is enriched in cobalt, nickel and manganese. The manganese and cobalt contents are particularly high compared to most nickel oxide deposits located in Western Australia.

Mount Thirsty: Mineralisation

The mineralisation typically starts from near surface to around 12 meters below surface where goethitic clays are present with an iron composition of around 30%. Deeper down the colour of the goethitic clays darken as the asbolane (manganese oxide mineral) content increases. This darkening marks the start of the cobalt enriched, high-grade portion of the deposit. Further down, the goethitic iron oxide colouring or dark colouring due to the asbolane diminishes with greenish nontronite and serpentine minerals becoming dominant (lower saprolite). Near the bottom of the lower saprolite zone, chalcedonic banding is common. High-grade cobalt is almost always associated with dark asbolane.

Drilling

696 Air Core (AC) holes, 14 Reverse Circulation (RC) holes, 21 Rotary Air Blast (RAB) holes, and 7 Sonic Core (SC) holes. Grid spacing is sufficiently close for the style of mineralisation at 50m x 40m on the eastern side and 50m x 80m on the western side.

Mount Thirsty: Logistics

The Mount Thirsty Project is located 16km northwest of Norseman, Western Australia. The Project is close to all necessary infrastructure (rail, road, power, gas, water, townsite, fibre optic and seaport). Access is via vehicle on a combination of sealed and un-sealed roads.
