The Olie quartz vein is exposed along Highway 24, about 5 kilometres north-northwest of Little Fort.

A ribboned quartz vein contains selvages of chlorite and rusty carbonate and local malachite and azurite together with tiny grains of chalcopyrite and a grey sulphide mineral of uncertain identification. The vein is 1 metre wide, dips approximately 60 degrees west and was traced for 10 metres. A sample of mineralized vein material (00PSC-14-2) yielded values of 1826 ppm copper, 569 ppm lead, 15 ppm silver and 704 ppb gold (Fieldwork 2000). Similar quartz veins elsewhere on the outcrop did not appear to contain metallic mineralization. The vein cuts a microdiorite sill that intrudes fine grained sedimentary rocks of the Mixed Volcanic-Sedimentary Unit of the Upper Triassic Nicola Group. The unit is composed of siltstone, sandstone, basalt, tuff, conglomerate, volcanic breccia, chert and dacite (Fieldwork 2000).

There is no record of work on the occurrence.
