major projects in Western Australia; the Greater Carlow Castle
gold-copper-cobalt project in the West Pilbara; the Paterson Central project
in the Paterson Province (located adjacent to Greatland Gold / Newcrest's

Section 2 Reporting of Exploration Results

Exploration done by other parties · Acknowledgment and appraisal of exploration by other parties. · Numerous exploration parties have held the area covered by the
current Osborne JV tenure previously. There is no reported previous
exploration for lithium bearing pegmatites on the tenements.
· No other exploration companies generated data was used in this
release.
· Regional RTP aeromagnetics and geology from Geological Survey of
WA.
· The area was previously explored by Fox Resources Ltd and Artemis
Resources Ltd with both focussed on nickel exploration.
Geology · Deposit type, geological setting and style of mineralisation. · The lithium bearing pegmatite zone trends WNW-ESE and is hosted
by strongly sheared sediments of the Regal Formation.
· The pegmatites occur as intermittent lenses in strongly sheared
sediments assigned to the Regal Formation and are located approximately 3km to
the north of the Sholl Shear Zone.
· The pegmatites are steeply dipping and up to 20m wide.
· The project area is underlain by the Archean Pilbara Craton,
specifically the West Pilbara Superterrane (WPST) of Hickman (2016). The
3280-3070 Ma WPST comprises numerous tectonostratigraphic packages (Sholl,
Regal and Karratha Terranes and the Whundo and Nickol River Basins) and
igneous complexes that have been variously affected by several tectonic
events. The easterly to east-north easterly trending Sholl Shear Zone (SSZ) is
a boundary for the regional rock packages. Metamorphic grade is higher to the
north of the SSZ, suggesting the present-day surface shows a slightly deeper
crustal level on the north side.
