The Youanmi Gold Mine is a gold mine 82 km south-southwest of the town of Sandstone. It is near the abandoned town of Youanmi, in the Murchison Region of Western Australia.
Youanmi mining operations were suspended in 1997 and the mine was placed into care and maintenance. Since 2019, it is jointly owned by Rox Resources and Venus Metals Corporation, with the former managing the site.
In 1994, Youanmi became the first mine to commercially use the BACOX process (previously owned by BacTech Mining Corp, which is now REBgold Corp).[1] This patented process, which is a proprietary of REBgold and BacTech Environmental, is a process of bacterial oxidation and bioleaching technologies that liberate precious metals from difficult-to-treat sulphide ores and concentrates, using naturally occurring bacteria.[2][3] The Wiluna mine uses a similar process, the BIOX process.[4]
The name Youanmi derives from a spring in the area and was first recorded in 1887. It was given to a surveyor by an old Aboriginal accompanying him, but its meaning is unclear.[5]
