The Lake Johnston Lithium-Nickel Project is located approximately 400 km east of Perth and 200 km southwest of Kalgoorlie in Western Australia.
The project consists of eight granted exploration licences covering a total of ~794km2.
The exploration ground extends to within 10 kilometres 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[1], 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[2].
