Charger (ASX:CHR) chase spodumene ‘Swarm’
Charger Metals confirm a hive of fertile stacked pegmatites up to 5 metres wide at the Medcalf Lithium prospect, part of the Company’s Lake Johnston Lithium Project in Western Australia.
Spodumene intersections in all but two of 17 holes within a 50m area remain open at each end and at depth.

The Company said the Medcalf Spodumene Prospect represents a swarm of anastomosing to tabular pegmatites that are members of the LCT pegmatite family and of the albite-spodumene type.
“Charger Metals’ maiden drilling program at Lake Johnston very encouragingly intersected numerous spodumene-bearing pegmatites within a 50m-wide zone,” Managing Director David Crook said.
“The program has provided critical information about the orientation of mineralisation aiding planning ahead of the resumption of drilling in early 2023.”

About the Programme
The reverse circulation (RC) drilling program was conducted at the Medcalf Spodumene Prospect in December 2022 and totalled 17 holes for 2,669 metres (Figure 2 and Table 1). Individual pegmatites intersected in drilling are up to 5m in width, have a strike direction of northwest-southeast and dip at a moderate angle (approximately -40°) towards the southwest (Figure 3).
Cross section A-A’ (See Figure 2) shows an interpretation of the pegmatite swarm, explicitly identifying the occurrence of apparent spodumene within each pegmatite (Refer to Note 1). The pegmatite thickness represents a maximum of 2m of internal waste and includes intervals where the pegmatite composition was ≥20% of the rock mass.
