Ann: Reconnaissance Exploration Commenced at Pilbara Gold Project, page-26

Mate I am putting up something from Novo's own website . Novo say themselves in that image that the DeGrey Supergroup is the equivalent to the West Rand and the Central Rand ! Have a look yourself page 34 of the Beatons Creek Technical report on the Novo website. There are plenty of examples of gold (which neither you or I know what type) historically found in the Constantine Sandstone and the Millindinna Intrusion .Have a look at the rough maps below and work out what tenements the yellow squares correspond to in the left image.
Even the ground DEG took an option on recently where they showed the big gnarly nugget is either in the Constantine sandstone or in the Millindinna Intrusion
