Ann: Burmeister Lithium Potential Defined, page-39

The southern Lake Tay area
Another interesting area in this respect is southern Lake Tay. There is a Warox site observation comment in Minedex where they note Pegmatite lithology. Most pegmatites are dusters so this isn't particularly special. An oddity about TG6 at Burmeister has been the absence of non-mineralised pegmatites. So the structure here is a known pegmatite outcrop near a Magentic anomaly high, with a strip of elevated anomaly towards the main anomaly high.

My view is biased, but it does look a lot like rotated Mt Marion magnetic anomaly. The first step would be soils/rock chips (and obviously more work on the higher priorities of Burmeister/Jaegermeister)
