The surface geology of the deposits is composed of quartzites, amphibolites, gneisses, shale and schists.
The magnetic anomaly of the Wortel is mainly due to the intrusions of the Wortel Suite that carries magnetite quartzite. Hoogoor is located northeast of Wortel deposit. The deposit forms almost circular oval shape with the magnetic signal stronger at the south.
No drilling done on Hoogoor anomaly.
