Manganese prospect. In 1957, the Geological Survey of Western Australia staff were flown around the Pilbara by Lang Hancock to look at manganese deposits. Hancock Prospecting Pty Ltd held several of these, and a call-in was made at the Mulga Downs Homestead. MC94 is the lease number for want of a name. 10 acres. Stated as beside homestead. Nothing could be seen but extensive exploration has occurred 3 kilometres to the south-east of the homestead. The 1957 investigation dismissed the deposit as low grade, with 3 to 4 feet of manganese material, estimated as 500 tonnes of commercial ore.
Map- Mulga Downs as listed on Google Earth is not where the homestead is, but generally applies to part of the land covered by the station.
