Charger Metals (ASX:CHR) has lodged a mining lease application (MLA 63/691) for the development of its 100% owned Medcalf Lithium deposit and Medcalf West exploration target, located within the Lake Johnston Lithium and Gold Project, approximately 450km east of Perth in Western Australia’s Yilgarn Province.
The application covers 3,644 hectares on Ngadju traditional lands, with the company acknowledging and respecting the Ngadju people as custodians.
The MLA encompasses the maiden Medcalf mineral resource estimate of 8.2 million tonnes at 1.0% Li₂O and the adjacent Medcalf West exploration target, estimated at 3–5 Mt at 1.0–1.4% Li₂O.
Both areas remain open for expansion, highlighting significant potential to grow the lithium resource in a region hosting the world’s largest spodumene province.
Charger plans to commence a further diamond and reverse circulation drilling program in January 2026, fully permitted for over 40 holes, to test extensions of the Medcalf resource and the limited-drilled Medcalf West target.
Managing Director Bryan Dixon said, "The Medcalf and Medcalf West deposits are strategically located within trucking distance of four spodumene concentrate plants, offering strong logistics advantages. The maiden resource validates two years of systematic exploration and positions Lake Johnston as a high-potential lithium project as global spodumene prices continue to rise."
Future mining is expected to combine conventional open pit and underground methods, with room for supporting infrastructure including waste dumps, a potential concentrator, tailings storage, and haul roads.
