Police say they have found no new evidence of missing four-year-old Gus Lamont as they conclude their fourth search for the boy - a day earlier than previously planned.
SA Police returned to the family's sheep station on Tuesday morning determined to find new evidence or rule out another location in the ongoing search for the missing boy, 61 days since he was last seen.
Police said this week's search involved the inspection of six mine shafts, and several locations were identified following analysis of aerial mapping and imaging conducted following recent ground searches.
"The inspection of the mine shafts, located between 5.5km and 12km from the Oak Park homestead, did not locate any evidence to assist in the investigation into Gus' disappearance," police said in a statement on Wednesday afternoon.
"Several of the shafts were relatively shallow and could be visually inspected but the remainder were up to 20 metres deep and specialised equipment was required to complete the searches."
Police said Gus's family had been advised of the results of the renewed search and were being supported by a victim contact officer.
The search has its own dedicated Task Force Horizon, which are at this time accompanied by STAR Group officers who are specialists in recovery missions.
Task Force Horizon officers have not ruled out returning to the property as the investigation continues.
