News from Chief Operating Officer Michael Rodriguez

Our most recent acquisition at Lake Johnson was secured following a detailed due diligence process by our experienced management team. Lake Johnson was shutdown in 2013 following an investment by the previous owners of approximately $15M in refurbishment costs in 2011. The operation ran for less than two years prior to being shutdown.


Lake Johnson is located approximately 330km south west of Kalgoorlie. The Lake Johnson plant is a 1.5MTPA nickel sulphide concentrator. LionOre completed an expansion in 2005. The concentrator has a three stage crushing circuit followed by a single 4.8MW ball mill in closed circuit. The flowsheet includes flash flotation and a standard downstream flotation circuit. Two Larox filters are available to recover a concentrate. A local island power plant supplies the power required for the concentrator. A 180 person village is located a short distance from the mine site with modern recreational facilities. Lake Johnson has historically produced a quality concentrate free of deleterious elements.


Over the next few weeks I’ll provide regular updates and more detailed information on our progress and activities in bringing Lake Johnston back into production - register here for updates.
