Koppie Aleen is a small copper deposit mentioned in Mineral Resources of the Republic of South Africa on the boundary of Roodekrans farm 492 JQ and Hennopsrivier 489, west of Pretoria close to Roodkrans mine. It was named Koppie Aleen by The south African Micromount Society due to the koppie (hill) that is a landmark feature close to the deposit. (thought to be pre-European)
