Man may have been attacked at SA mine

An injured man who may have been assaulted at a South Australian mine has been flown to hospital.

Police have so far been unable to speak the man, who sustained a head injury but whose condition is not serious.

The man sought assistance from a householder at Silverton, on the Fleurieu Peninsula, just after 2am on Tuesday.

Initial investigations suggest he may have been present at or assaulted at the nearby Talisker Mines.

Police, including crime scene investigators and a police dog, are searching the area.
