Glenburgh Station is 111 kilometres east south-east of Gascoyne Junction. The Glenburgh prospects extend along a course north-east to south-west, about 10 kilometres north north-west of the pastoral station homestead. There is a strong chance a mine will be developed here one day.

Discovered by Helix Resources in 1994, and acquired by Gascoyne Resources from 2010. A feasibility study was conducted in 2013.

The prospects contain a JORC Indicated and Inferred resource of 21.1 Mt of ore at 1.5 g/t Au for 1.0 million ounces. The site is of interest as gold deposits are rare in upper amphibolite, and there is almost no alteration assemblages surrounding the deposits.

The prospects are in the paleoproterozoic upper amphibolite facies of the Glenburgh Terrane. Gold is free and disseminated within quartz-biotite-garnet gneiss, amphibolite, and quartz-chlorite veins. The lodes are discontinuous trending east north-east, within tight folds, dipping steeply north. It is offset by the Deadman Fault, which bisects the area.

Rock units are more specifically quartzofeldspathic biotite-cordierite-sillimanite-spinel-garnet gneiss, with inclusions of minor mafic granulite, mafic schist, pelite, psammite, metapegmatite, metagranite, amphibolite, Fe metasandstone, and quartzite. This dips either steeply north or south.

There is some disseminated pyrrhotite, pyrite and minor chalcopyrite.

The deposit was formed in a package of sedimentary rocks before the peak of the high grade metamorphism during 2005-1950 Ma Glenburgh Orogeny. The gold has been described as enigmatic, usually referring to an unknown or little understood process of how it was formed.

Prospects include from the north North-East 3, Zone 126, Zone 102, Hurricane, Shelby, Mustang, Apollo, Icon, Tuxedo, and Torino.
