The Lake Johnston Lithium-Nickel Project is located approximately 400 km east of Perth and 200 km southwest of Kalgoorlie in Western Australia. The exploration ground extends lie approximately 110 kilometres east of the world class Mount Holland Lithium mine, with an expected output of 380,000 tonnes of spodumene concentrate each year[1], and approximately 40 kilometres south of Charger Metals[2] Lithium Project.
The project consists of one granted exploration licence E63/2159 (Pegasus Prospect) covering a total of ~28km2. Recent exploration includes surface sampling, mapping, and an RC drill program.
The exploration ground is east of the world class Mount Holland Lithium mine and concentrator being developed under the Wesfarmers Limited/SQM Australia Pty Ltd joint venture. The Mt Holland Lithium project includes the Earl Grey Lithium deposit with a reported Mineral Resource of 189 million tonnes grading 1.5% Li2O[3], making it a globally significant high-grade hard rock lithium deposit.
The ground also sits to the immediate west and north of Poseidon Nickel Limited’s Lake Johnston Project, encompassing the Maggie Hays/Emily Ann mine and associated processing plant, which is currently under care and maintenance. The Emily Ann Mine historically produced 46,000 tonnes nickel with a resource grade averaging 4.1% nickel[4].
