In October 2019, Enterprise lodged applications for four large exploration licences over deep palaeo-valleys centred approximately 35km north-northeast of the wheatbelt town of Perenjori. (Figure 1) The tenement applications have a total area of 697 km2 and cover ~120 km of ancient (+34 million years old) drainage systems which have their headwaters in the central part of the Yilgarn Craton. Airborne geophysical surveys previously conducted by Enterprise provide evidence that deeply incised (100m – 150m depth) palaeo-valleys lie buried below the broad shallow valleys and lakes NNE of Perenjori.
Subject to the tenements being granted, Enterprise plans to explore the palaeo-valleys for sub-surface brine deposits using aircore drilling methods. The ultimate goal is to produce Sulphate of Potash (K2SO4 or SOP) via surface evaporation (and processing) outside of salt lakes, within PVC lined evaporation ponds. The Perenjori Project area is well serviced with a 245km railway from Perenjori to the port of Geraldton and has established infrastructure in the nearby wheatbelt towns of Morawa and Perenjori.
