Located about 40 kilometres north-west of Coolgardie, bordering the east side of the Jaurdi Hills Road. The small Black Cat North open pit is just to the south-west on the west side of the road. The Pride of Jourdie area contains extensive remnants of battery sands, some trenches, possibly old shafts, and disturbed areas. The separately owned Pride of Jourdie North mine also had a battery, and it appears the sands have been shifted around over the years with individuals carting the sands away to be cyanided, so what is left covers one extensive area.
The earliest report from the mine (and in fact the Jaurdi Hills area) was 1897. It was operated by the Jourdie Hills Gold Mining Company, who released little information to the public, much to the annoyance of mining analysts at the time. From 1897 to 1907, the mine produced 16 807 ounces of gold from 28 287 tonnes of ore. After this the mine was let on tribute, until about 1915.
The Jaurdi Hills area is part of the Archaean Dunnsville-Ubini Greenstone Belt, folded around the Dunnsville and Doyle Dam grandiorite plutons, forming an antiformal structure. The greenstone belt is basalt with thin interlayered black shale. The lower sequences of the greenstone belt is intruded by numerous dolerite and gabbro sills. Jaurdi Hills is on the west side of the Dunnsville/Doyle Dam granodiorite. Gold is found at Jaurdi Hills either as Archaean lode deposits, or supergene enrichment where gold has mobilised via highly saline solutions in saprolite.
At the Pride of Jourdie, and neighbouring deposits, gold is found either in large reefs of white to glassy quartz over considerable strikes, but a low gold grade. Or, gold is found in small quartz leaders, with locally high gold grades, the leaders often found parallel to each other. These gold bearing quartz veins are found in black shale horizons, also the porphyry and gabbro contacts, and finally the lower basalt unit. There is also an alteration envelope at Pride of Jourdie.
