The Yallalong project is located about 220km to the northeast of the port of Geraldton and covers an area of about 65.5km2. The project area lies within the Yallalong Basin on the western margin of the Yilgarn Craton. The area has been under explored and it is only in more recent times that the prospectivity of these basin areas has been recognised. The project area is considered to be prospective for gold mineralisation associated with structures related to the crustal scale Darling Fault and Ni-Cu–PGM mineralisation related to mafic– ultramafic intrusions
The Discovery prospect gold mineralisation is associated with very high-grade antimony (Sb) with up to 60.4% in quartz veining. This tenement remains largely untested for gold mineralisation. The mafic intrusions within the project area have not been explored in any detail but have returned elevated nickel, copper and platinum geochemistry. The area has a similar setting to Proterozoic craton edge Ni-Cu-PGM mineralisation such as at Chalice Mining’s Julimar deposit located northeast of Perth.
