Police return to remote property where four-year-old Gus disappeared

Police have returned to the remote South Australian property where four-year-old Gus Lamont disappeared and have spoken to his family.

The boy was last seen playing on a mound of dirt about 5pm on September 27 at the Oak Park Station homestead, about 43 kilometres south of Yunta.

Intensive searches have failed to locate Gus and the latest was suspended late last year.

Today, police confirmed they travelled last week to the property and spoke with the heartbroken family.

"We've taken statements with the family, we've had to go through those statements with the family, and that's just part of the normal investigational process that we go through," Detective Superintendent Darren Fielke said.

"We continue to engage with them.

"They went through a pretty horrid Christmas without Gus, and we check-in with the family regularly."

Lamont was last seen by his grandmother.

About 30 minutes later, he had vanished and a full-scale search was soon launched.

Crews comprised of police, emergency services, the defence force and volunteers have combed through the property, mine shafts and bodies of water in what is one of the largest searches for a missing person in South Australia.

They have failed to locate any trace of Gus.

The four-year-old with blond curly hair has been described as a shy but adventurous child.

His family have said in a statement they are "devastated" and "deeply distressed" by his disappearance.
