Gus Lamont Search Intensifies as Police Probe Remote Mine Shafts in South Australia

Four-year-old Gus Lamont vanished from a remote South Australian station five months ago. The last sighting was near his family’s Oak Park homestead on September 27, 2025. An immense ground and air search has found no trace of the boy. Police have now shifted focus to a new, challenging frontier.Authorities are investigating six previously unknown mine shafts near the property. This marks a critical new phase in one of the state’s largest missing person operations. According to reports from 1News and 9News, specialized teams are using cameras and equipment to search the deep, old shafts.

Exhaustive Searches Yield No Clues, Prompting New Direction

The initial response was massive. Hundreds of police and volunteers combed the harsh outback terrain. They searched on foot, on horseback, and from the air for weeks. The ground search alone covered 95 square kilometers.In a major operation, police drained a large dam near the homestead. It held over 3 million liters of water. Divers found nothing after a meticulous search. This ruled out drowning on the property as a likely scenario.Every possible lead has been pursued with relentless determination. Yet, the landscape has kept its secret. The lack of evidence has been both puzzling and deeply frustrating for all involved.

Focus Turns to Hidden Hazards of the Outback Landscape

The newly identified mine shafts are between 5.5 and 12 kilometers from the homestead. They were not fenced and were missed in earlier sweeps. The STAR Group and Task Force Horizon are leading this dangerous work.Officers spent a full day lowering equipment into the first shafts. High winds made the operation difficult and slow. No evidence related to Gus was found in the initial probe of these sites.This three-day operation underscores the investigation’s complexity. The outback presents unique dangers, with historical mining works scattered and often unmapped. Eliminating these locations is a painstaking but necessary task.

Investigation Finds No Signs of Foul Play, Family Cooperates

Police have consistently stated there is no evidence of criminal activity. The search remains a missing person case. The family has cooperated fully with investigators from the very beginning.A dedicated victim contact officer supports the Lamont family. This cooperation has been vital for the investigation’s progress. It allows police to focus on searching rather than speculation.Deputy Police Commissioner Linda Williams reiterated the force’s commitment. She said they are determined to explore every avenue to find Gus and provide closure. The human element drives this prolonged and difficult mission.
