It is situated at the intersection of the R503 and R507 routes. The town is situated on an ancient geological feature known as the Hartbeesfontein basin, which is the source of the gold found on its southern rim. Underground water occurs in abundance in dolomitic aquifers of the region. When the water is however allowed to seep into mines it is oxidised and polluted by the exposed iron pyrites. As of 2005 when Buffelsfontein mine went out of business, it became a burden on the remaining mines to keep the interconnected tunnels free of water.
