The Garden Well Gold Mine is 90 kilometres north of Laverton, and about 2 kilometres east of the Erilstoun Road.
It was a virgin discovery made by Regis Resources Limited in 2009. This company owns the tenements covering the Duketon Goldfield to the north, and northern part of the Erilstoun Goldfield.
Operations started at Garden Well mid 2014, with an expected mine life of 7 years. It is a large industrial scale gold mine, with a shallow oxide pit, much tailings, and a processing plant. Water soaked alluvium was planned to be pumped several kilometres to the north-west into the pits at the abandoned Rosemont Gold Mine. As the latter mine is active again, it is uncertain if this took place, or was dumped closer to the mine, in what appears to be an extensive tailings area.
The deposit is found in the Duketon Greenstone Belt, on the eastern limb of the Erilstoun Syncline. The deposit is covered by palaeochannel alluvium to 30 metres thick from the surface, with no surface gold outcropping. Gold mineralisation occurs in clay rich residual Archaean saprolite, with some sub-horizontal supergene gold development in the upper part of the saprolite. There is a hypogene zone (formed by ascending water) of quartz-dolomite-fuchsite-chlorite-pyrite.
Gold is found in oxide ore to 70 metres below the base of the palaeochannel, and hypogene ore to at least 400 metres deep. The oxide zone is 80 to 100 metres wide, moderately east dipping, in clay rich residual saprolite.
The host rocks is strongly sheared, moderately east dipping ultramafic rocks, in contact with the overlying, moderately east dipping. argillaeous sediments. The shear zone below the top of the fresh rock consists of a 50 to 70 metre wide strongly altered quartz-dolomite-fuchsite-chlorite-pyrite zone in ultramafic rocks. Most of the gold is found in this, and late stage quartz-carbonate veining.
Floods temporarily closed the mine early 2014 and 2015.
The JORC 2015 total resource is 86.7 Mt @ 0.89 g/t yielding 2.47 Koz of gold.
