A single adit exposes a series of Tertiary lake bed deposit where searlesite occurs.

Near Mina. Large shallow lithium-boron deposit.

Rhyolite Ridge project covers two separate lithium-boron deposits (North Basin and South Basin) located 4km apart. The mineralisation occurs in flat-lying sedimentary rocks as two or more stacked layers or lenses. The sedimentary rocks are up to 300m thick and the mineralised layers within are 20-70m thick. The mineralised layers contain lithium only (clay-rich) and lithium-boron (clay-poor) mineralisation.
