Siga Hills is located in the greenstone belt of southern Victoria Lake��and most gold deposits in this area are belonging to typical greenstone belts BIF�� The gold deposit occurs in the banded iron formation��and the gold bodies are exactly controlled by both rocks and structures�� The magnetic survey shows that there are three mag- netism anomaly belts (M1��M2 and M3) in Maheiga gold deposit��which caused by BIF and gold mineralization�� Soil geochemical survey expresses that the element Au has a relationship with As and Sb�� Comparing with the infor- mation of gold deposits in this region��the authors proposed three areas as the prospecting direction in Siga Hills�� including N-S extended line of Maheiga gold mineralization belt and the contact zone with granite in the east��the N-S belt of Siga Hills and the area between Siga Hills and Maheiga��
