TG Metals (ASX:TG6) achieved concentrates of up to 6.31% lithium oxide using simple dense media separation (DMS) processing from metallurgical testing at the Burmeister deposit within the Lake Johnston lithium project in Western Australia.

The results "provide a positive start to underpin future engineering studies and confirmatory test work," the company said in a Wednesday filing with the Australian bourse.

Flotation test work results will be reported in November, including assays for the semi-continuous DMS test work, magnetic separation, and de-sliming.

Shares of TG Metals rallied 17% in recent trade.
