Abstract

The deposits, in Western Australia, lie in the Agnew-Wiluna greenstone belt in a sequence of mafic to ultramafic volcanic rocks and associated interflow sediments. The dominant structure in the area is the Waroonga shear zone. Gold mineralisation in the orebodies is closely associated with quartz veining within medium- to coarse-grained sandstone units. Mineralisation occurred after peak metamorphism and was related to reactivation of D1 faults and the subsequent creation of S3 structures. From 1898 to 1996, 157 823 oz of gold were recovered from the deposits. Resources at 31 December 1996 were 668 000 t of ore at 2.6 g/t gold for Genesis, 832 000 t at 4.5 g/t gold for New Holland and 512 000 t at 9.2 g/t gold for the New Holland South underground deposit.<br />The deposits, in Western Australia, lie in the Agnew-Wiluna greenstone belt in a sequence of mafic to ultramafic volcanic rocks and associated interflow sediments.
