Charger Metals NL confirmed that drilling has resumed at the Medcalf Spodumene Prospect, at its Lake Johnston Lithium Project in Western Australia. The Medcalf Spodumene Prospect represents a swarm of anastomosing to tabular pegmatites hosted in sheared amphibolite. Medcalf spodumene-pegmatites are members of the lithium-caesium-tantalum (LCT) pegmatite family (albite-spodumene type) and spodumene is clearly observed in many outcrops.

Spodumene is the preferred mineral for the commercial production of lithium, which is one component of modern lithium batteries. Reverse circulation (RC) drilling commenced during December 2022 and has now resumed, with 20 holes planned. Current laboratory turn- around is approximately 7 weeks following the submission of samples.

Spodumene-pegmatites were intersected on each of the 3 sections drilled to date. Individual units, up to 5m in width, have a strike direction of north-west - south-east and dip at approximately -40° towards the south-west (Figures 1 and 2). Thicker pegmatites are recorded on the north-western-most drill section indicating a possible north-westerly plunge to the mineralisation.

The Lake Johnston Lithium Project is located 450km east of Perth, Western Australia. Lithium prospects occur within a 50km long corridor along the southern and western margin of the Lake Johnston granite batholith. Key prospects include the advancing Medcalf Spodumene Prospect discovery and much of the Mount Day LCT pegmatite field, prospective for lithium and tantalum minerals.

The Lake Johnston Lithium Project has attracted considerable interest due to its proximity to the large Earl Grey Lithium Project under development by Covalent Lithium Pty Ltd. (manager of a joint venture between subsidiaries of Sociedad Química y Minera de Chile S.A. and Wesfarmers Limited) located approximately 70km west of the Lake Johnston Project. Mt Holland is understood to be one of the largest undeveloped hard-rock lithium projects in Australia with Ore Reserves for the Earl Grey Deposit estimated at 189 Mt at 1.5% Li2O2.
