Detour Road mine is about 5 kilometres east south-east of Sandstone and is marked by a tiny oblong abandoned open pit.
It is on the north-east margin of the Sandstone Greenstone Belt, in close proximity to the Edale Shear, with intercalated ultramafic rocks, sedimentary rocks, and basalt, striking north north-east, and intruded by dolerite/gabbro.
Anomalous nickel, chromite, and copper values was found, with subordinate gold. In one spot there was a narrow zone of gold mineralisation, within subordinate quartz veining, hosted by altered dolerite, and flanked by high magnesium basalt and shale. (Possibly where the present pit is). There was also scattered lead values in the area.
The nickel is associated with secondary enrichment, 10 to 20 metres below the surface, in weakly to moderately oxidised ultramafic rocks, but decreases rapidly below this depth. It consists of talc-serpentinite-disseminated pyrite mafic, and tremolite-chlorite schist.
