The project is located only 40 kilometres from the world class Pilgangoora Lithium-Tantalum Project owned by Pilbara Minerals Ltd (ASX:PLS).
The results from the maiden sampling program at King Col include a peak of 4.22% lithium associated with a small outcrop of the lithium bearing mineral, lepidolite.
De Grey also assayed eight additional samples ranging from 0.15% to 2.5% lithium along a zone of 1.5 kilometres.
The entire 7.5 kilometres pegmatite trend is associated with anomalous lithium-cesium-tantalum (LCT) pegmatite elements.
As a comparison, the nearby 129 million tonnes (1.22% lithium) Pilgangoora Lithium-Tantalum Project occurs in pegmatites over 9 kilometres of strike length.
A follow-up program of detailed rock chip and soil sampling is currently being planned and is expected to commence during October.
De Grey’s objective is to define anomalous target zones for subsequent drill testing.
Last month, drill assays confirmed silver and zinc mineralisation at the Tabba Tabba prospect within the Turner River Project.
Significant results from the 12-hole program included 9 metres at 90.1 g/t silver, 5.56% zinc from 56 metres and 9 metres at 58.7 g/t silver, 2.68% zinc from 24 metres.
