Cowarna Downs Station is a pastoral station 105 kilometres east of Kalgoorlie, the homestead just south of the Trans Australian Railway Line. Karonie is a small railway siding on this station.
The station includes the Aldiss-Karonie gold district, part of the Mount Monger Goldfield. This area most significantly includes the Karonie Gold Mine, and several other north-south trending gold prospects over a distance of 40 kilometres. The gold deposits are listed in Mindat under those regions rather than this station.
The gold prospects are classified into the Admiral, Batavia, and Challenger Trends, hosting a large number of discrete anomalous zones. The geology of the area consists of Archaean aequences comprising high-magnesian mafics, andesites, intermediate to felsic volcaniclastics, granodiorites, syenites, porphyries, shales, banded chert and other sediments. Gold mineralisation is hosted by the intermediate volcaniclastics and porphyritic basalts. The overlying shallow cover is a very complex mix of stripped Archaean regolith profiles, overlain with reworked Archaean sediments, Tertiary sediments, windblown sand, paleo-drainage channels and usually dry salt lakes. Specifically, the gold deposits strike north-south, dipping west, in ortho and para amphibolites, with interlayered felsic sills or tuffs.
The area also contains some nickel prospects and a precious opal mine.
