North Kiaka Quartzite Mine

Closed 10 Jul 2022

Opened 4 Jul 2022


Simcoa Operations Pty Ltd is proposing to establish a new quartzite mine approximately 15 km north of Moora, in the Wheatbelt region of Western Australia, and 2 km north of the existing mine.

The proposal will include the establishment of an above groundwater mine pit, waste rock landform, infrastructure corridor and associated infrastructure. Quartzite would be trucked to Simcoa’s existing smelter in the Kemerton Strategic Industrial Area 17 km north-east of Bunbury. 

It is anticipated the proposal will generate approximately 130,000 tonnes per annum of lump quartz and extend Simcoa’s operations by 18 years. 

The proposal would require the clearing of 17.12 hectares (ha) of native vegetation, within a 44.59 ha disturbance footprint, and a development envelope of approximately 216.42 ha. 

Why your views matter

At this initial stage of the EIA process, comment is simply sought on whether or not the EPA should assess a proposal and, if so, what level of assessment is considered appropriate.

What happens next

Following the seven day public comment period and consideration of any comments received, the EPA will decide whether or not this proposal requires environmental impact assessment and, if so, what level of assessment will be applied.

The EPA's decisions on level of assessment are released each Monday on the EPA's website.
