The company’s granted exploration licence covers an area of 351 square kilometres at the Lake Gregory salt lake.
Lake Gregory was targeted following review of a Geoscience Australia analysis, which identified the potential of Lake Gregory to host lithium brines, potash and uranium mineralisation.
GB Energy’s works included the excavation of nine hand-dug pits across Lake Gregory to a total depth of between 0.8 to 1.1 metres below ground surface.
Highly saline water was recovered from five of the nine pits using a pump.
A detailed analytical suite has been designed to ascertain the potential for lithium, potassium and other important elements from the brine.
The results are expected in the coming weeks.
It is worth noting that lithium brines occur where ground waters percolate through lithium-bearing source rocks and deposit in a closed basin.
Importantly, Lake Gregory is fed by a catchment containing rocks with unusually high levels of uranium and lithium.
Last month, GB Energy expanded its Northern Territory portfolio with tenement applications targeting nickel-copper-platinum group elements (PGE) and uranium.
