The brine samples taken on about 1 sq. km grid have confirmed that the northern area of salar is the lowest concentration area of the salt lake.

Further, at the centre of the salar, the lithium concentration from initial samples reached a maximum of 285 mg/l, within a zone of predominantly 104-150 mg/l lithium concentration. 

Apart from the brine sampling, GW1 also conducted a passive seismic survey to extract valuable information related to the thickness of salt lake sediments.

The company has identified clear high confidence reflectors in the south of the project area suggesting the salt lake sequence in the order of 300-600m thick.

While on the north side of the salt lake, a shallow reflector is interpreted to reduce the signal from below this feature.

Future plans

The company plans for fieldwork to further evaluate the brine concentration and the possibility of a higher concentration of brine can be confirmed by additional drilling.

Regarding the geophysical survey work, the company plans passive seismic measurements to better define the distribution of units and the presumed thickness of the salar sediments.

Greenwing is also considering an initial drilling program following the receipt of relevant permits to allow drilling on the project.
