Name of the Project
Lake Johnston processing plant.

Location
Western Australia.

Project Owner/s
Poseidon Nickel.

Project Description
The project entails the refurbishment and operation of the Lake Johnston nickel processing plant and associated infrastructure.

The plant started operating in 1998, with the original Lake Johnston concentrator treating ore from the Emily Ann underground nickel mine.

There have been several expansions since then, with the most recent being a major expansion to 1.5-million tonnes a year throughput capacity in 2006 to treat ore from the Maggie Hays underground mine.

The plant was again refurbished in 2011 before being placed on care and maintenance in 2013. In 2017, all infrastructure was removed from the Maggie Hays mine and the workings were allowed to flood.

Based on previous studies undertaken on mining the remaining Maggie Hays orebody, the scoping study is based on a maximum throughput of 900 000 t/y.

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
None stated.

Capital Expenditure
According to the scoping study, the Lake Johnston processing circuit and associated infrastructure could be refurbished for about A$31-million.

Planned Start/End Date
The refurbishment will take about seven months to complete.

Latest Developments
Poseidon will review the previous studies on mining the remaining Maggie Hays resource and start an aggressive exploration programme aimed at increasing the resource base at Lake Johnston.

Key Contracts and Suppliers
GR Engineering Services (scoping study).
