KCGM Hidden Secret Project

Closed 2 Dec 2014

Opened 26 Nov 2014


Kalgoorlie Consolidated Gold Mines (KCGM) has referred its proposal for mining of the Hidden Secret underground gold mine from the Mt Charlotte underground mine. Mining will be between 215 and 440 metres below ground surface and will not require any clearing.

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