Mount Keith nickel operation
The Mt Keith deposit is a low-grade disseminated sulphide ore which is mined from a large open-pit operation. The ore is crushed and processed on-site to produce nickel concentrate. The Mt Keith satellite mine (Yakabindie) entered production in December 2019 and is now the primary source of feed to the Mt Keith concentrator. From the very beginning, the high MgO content in the ores at Mt Keith and the common occurrence of talc meant that the principal challenge facing the low grade Mt Keith deposit would be nickel recovery values.
