Ann: Acquisition of Advanced Croydon Top Camp Gold Project, page-5

Does anyone here know anything about the history of Top Camp that they can share?

@bobdplaya found this, but I think there may be more than one 'top camp' in the Pilbara:
Top Camp was discovered by three prospectors Wilson, Ford & Donald Campbell in 1890 & over 30,000 ounces of recorded pure gold was found here between that period & 1940 when the Australian Government, to booster the WWII coffers did some extensive dry blowing operations here.
The biggest nugget was found by a prospector named Jack Ryan which weighed in at 130 ounces. He also found two more at 90 & 123 ounces.
At one time there were over 1000 prospectors mining the area. Shaft creek has a 70ft shaft reputed to  70 ounces of gold (one ounce per foot) from what I heard.
