Mlc2318. The announcement on 9 January had this "Lake aims to produce at Kachi a high quality, low impurity product capable of attracting premium pricing. Lab testing has shown that lithium concentrations of 30-60,000 mg/L lithium can be produced from brines of ~300
mg/L lithium in a few hours using the Lilac process.
Previous ann stated "Lake recently announced a maiden resource for Kachi of 4.4 million tonnes lithium carbonate equivalent (LCE)
within an exploration target of 8-17 million tonnes LCE grading in the range of 310 mg/L to 210 mg/L lithium".
Brine weighs 1kg per litre, but, density of the salt from Kachi is unknown. Maybe you can knock around with those numbers over the 20,000 litres to give you a rough guide.
