Charger Metals NL (ASX: CHR, ‘Charger’ or ‘the Company’) is pleased to announce that assay results from soil sampling completed earlier this year have identified several new lithium targets at the Mt Gordon tenement of the Lake Johnston Lithium Project, Western Australia.
- Latest soil sampling programme across the Mt Gordon tenement (100% Charger) of the Lake Johnston Project has identified several new lithium targets for follow-up exploration
- Largest identified soil anomaly (>100ppm Li2O) extends for over 3km and lies adjacent to the tenement boundary with TG Metals Ltd (ASX:TG6) which hosts the recent Burmeister lithium discovery1
- Planning and permitting has commenced for follow-up air-core (AC) and reverse circulation (RC) drilling on the Mt Gordon tenement
- Preparation is ongoing for further drill programmes at the Lake Johnston Project, including diamond drilling at the Medcalf Spodumene Prospect
The results show large expanses of the tenement are anomalous for lithium in soils. Of note, several of these areas contain lithium in soils over 46 ppm Li (>100 ppm Li2O), including one anomaly that extends for more than 3km along the tenement’s western boundary which is immediately adjacent to TG Metal Ltd.’s (ASX:TG6) recent Burmeister lithium discovery (Figure 1).1
Charger’s Managing Director, Aidan Platel, commented:
“The soil geochemistry results from our 100% owned Mt Gordon tenement are very encouraging. The size and strength of the lithium soil anomalies are significant, especially in the context of the successful Burmeister lithium discovery on the adjacent tenement (TG Metals Ltd) which resulted from drilling of a lithium soil anomaly. 1
Our technical team will now expedite plans and permitting for follow-up exploration at Mt Gordon, including AC and RC drilling. In parallel we continue to work towards further planned drill programmes for the Lake Johnston Project, including diamond drilling at the Medcalf Spodumene Prospect and a maiden RC drill programme at the Mt Day Prospect.”

Technical Discussion
Soil sampling was completed in the June Quarter 2023 across the Mt Gordon tenement area, sampling at 50m east-west spacings on lines 400m apart. The samples were sieved to 250µm (i.e. fine-fraction soil samples) and assayed at Intertek for a full multi-element suite. The results show several lithium in soils anomalies that warrant further exploration, including a large (3km long) anomaly over 46 ppm Li (>100 ppm Li2O) that trends sub-parallel to the geology (NNW-SSE) along the western tenement boundary.
The results also demonstrate a dendritic pattern in places that suggests transported cover in the form of a historic alluvial channel. In these areas AC or shallow RC drilling will be necessary to assess the underlying basement geology for potential lithium-bearing pegmatites.
