Six contiguous ELs applications cover all of Lake Amadeus in the NT. The applications include 1,010km2 of lake area along a 130km length. The eastern boundary is contiguous with the Karinga Lakes Project and corresponds to the ALRA/pastoral boundary. The Lake Amadeus sediments are known to be much thicker than at Karinga. The best historical potassium assay is a BMR sample from a spring just off the southern edge of Lake Amadeus itself. This sample had 6,100(mg/l = ppm) potassium (over twice the cut-off concentration used in the Karinga Lakes Resource). Newmont gave a brine assay of 3,950ppm potassium at an unspecified location "from a soakage near the surface of the lake". Newmont also drilled twinned holes into the Bitter Springs Formation "basement" under Lake Amadeus (plotted in the following Figure). The Bitter Springs aquifer at 80-110 m depth did not contain significant potassium at that location.
A third meeting with the Traditional Owners of southeastern Lake Amadeus and the Central Land Council was held at Yulara in late June 2016. Unfortunately after the reporting period, the Traditional Owners came to a decision that there was to be no exploration on Lake Amadeus at this time and accordingly the applications are now under moratorium for the next 5 years. Verdant Minerals remains the applicant over that period at zero cost.
Six contiguous potash applications over Lake Amadeus. Yulara Creek Spring (BMR Sample 90201) and the collars of Newmont's twinned drillholes, one recorded as a waterbore RN011755, plotted on the Lake Amadeus applications. Aboriginal land in yellow. These Lake Amadeus applications abut Karinga Lakes to the east.
