The Waratah Well project is located approximately 20km northwest of the regional town of Yalgoo in the Murchison Region of Western Australia.
Tantalum and locally lithium bearing pegmatite sills and dykes crop out over a 3km x 2km area with a range of dips. Lithium rock chip sample grades up to 2.09% Li2O in the north-western portion of the target area. The key lithium target is the blind lithium spodumene mineralisation beneath the tantalum bearing dykes, a geological architecture similar to that noted at the Bald Hills lithium mine and a similar picture that can be noted at Liontown’s Kathleen Valley lithium project whereby relatively narrow surface pegmatite dykes merge at depth to form a thick flay lying lithium spodumene rich sill.

New drill results confirm the presence of high-grade lithium below the depth of weathering, returning significant lithium including:
- 14m @ 1.0% Li2O, incl 8m @ 1.5% Li2O.
- 10m @ 1.4% Li2O, incl 6m @ 2.0% Li2O.
- 27m @ 0.8% Li2O (true width 10m), incl 12m @ 1.2% Li2O (true width 6m).
Lithium mineralisation has been identified by laboratory XRD analysis as containing up to 84% petalite. High-grade petalite is not well documented in Western Australia but is known in several overseas deposits. An example of a lithium deposit containing significant petalite is the Arcadia lithium deposit in Zimbabwe formerly owned by Prospect Resources Ltd (ASX:PSC). Prospect reported a JORC 2012 Mineral Resource of 72Mt @ 1.06% Li2O1 and then subsequently completed a feasibility study and pilot plant before divesting its 87% project interest for $US378M ($US422M on a 100% basis)2 as announced by ASX:PSC on 23-Dec-21, highlighting petalite as a potential significant economic contributor to lithium projects.
