Nickel was mined here by Western Mining Corporation from three small pits. Only general geology information found. There is an oxide zone of iron and silica enrichment, followed by a smectite clay zone, then a saprolite zone containing magnesium rich clays. This is all underlain by ultramafic rocks of the Walter Williams Formation, cut by the west north-west trending thin dolerite SM7 Dyke.
Ernienickelite is named after Ernest Nickel, a CSIRO mineralogist, who wrote papers on several new Western Australian species across the 1970s to 1990s. It occurs as thin almost circular plates 0.5 x 0.5 x 0.02mm, or as rosettes of randomly orientated plates to 0.8mm. The crystal colour is black with a red/brown cast, occurring in cavities in quartz, in Ni-Co rich laterite, associated with a weathered ultramafic body. Specimens do not appear readily available from the location.
A look at satellite images in 2018 indicate the pit may have been filled in.
