Lake Throssell

Overview

The Companies Lake Throssell Project has a Total Mineral Resource Estimate of 14.3Mt of drainable Sulphate of Potash at 10.4kg/m3 SOP.

The Lake Throssell Sulphate of Potash Project is approximately 1080 km² of granted and pending tenements, covering 190 km² of salt lake playa and over 70 km of underlying interpreted palaeochannels. The Project is located 170 km east of Laverton on the Great Central Road connecting Laverton to Alice Springs.

Surface brine pumping trials have demonstrated the abstraction potential for the lake surface aquifer returning samples of up to 13.54kg/m3 SOP aligned with current modelling.

Air-core drilling to a depth of 144m has identified high-grade brine returning samples of up to 12.93kg/m3 SOP, with an average grade of 10.01kg/m3 SOP.

Auger sampling has identified high-grade surface brine samples of up to 14.80 kg/m3 SOP with an average grade of 11.80 kg/m3 SOP.

Trigg believes that Lake Throssell has the potential to host a sizeable high-grade SOP endowment and is the Company’s strategic focus.
