Auditing mine site perimeter defences
A practical framework for auditing perimeter, gate and gold room controls on a working mine site.
A mine site perimeter is only as strong as the weakest control on it. Auditing that perimeter properly means walking the fence line, watching the gate at shift change and reading the incident log in the same visit.
Perimeter
The audit starts at the fence. Line of sight, lighting, patrol frequency and sensor coverage are checked against the site map and the current threat picture.
Gaps are noted with a proposed remedy and a realistic cost. A perimeter recommendation that cannot be funded is not a recommendation.
Gate and access
Access control is where most sites lose ground quietly. Screening discipline, vehicle inspection and pass management are observed at real shift changes, not on a scheduled walkthrough.
Gold room
The gold room audit reviews access, dual control, camera coverage and the reconciliation record. The strongest control is a well-designed process that leaves no single point of trust.
