[9] New Celebration became a subsidiary of Hill 50 Gold in August 2001, when Newcrest sold the mine for A$10 million.

[15] Ore from the South Kalgoorlie mine is processed at the nearby Jubilee Mill, commissioned in 1987,[15] which, at one point during Dioro's ownership, also processed ore from the Frog's Leg Gold Mine, which Dioro owned 49% of.

Avoca, owner of the Higginsville Gold Mine and Ramelius, owner of the Wattle Dam Gold Mine, both in the area south of Kalgoorlie, were both interested in acquiring Dioro to combine their existing operations with Dioro's.

[19] Avoca, owner of the mine at the time, merged in with Anatolia Minerals Development Limited in 2011 to form Alacer Gold.

[21] In 2016, Metals X and Westgold de-merged, with the latter retaining ownership of the gold mining operations, including South Kalgoorlie.

[24] In July 2022, Northern Star announced that it would idle the Jubilee mill in an effort to cut cost.
