Summary:

The SNM (Savannah North mineralisation) is based on mining ore associated with the Savannah Intrusion; a palaeo-proterozoic mafic/ultramafic magma conduit. The Ni-Cu-Co rich massive sulphide mineralisation occurs as “classic” magmatic breccias developed about the more primitive, MgO rich basal parts of the conduit.

Magmatic Ni-Cu-Co sulphide Resources hosted by the Savannah North Intrusion (SNI) located to the north of the Savannah Mine.

The Savannah North mineralisation dips moderately (40- 45 degrees) to the north-west and comprises two main zones, the Upper Zone is developed on the basal contact of the North Olivine Gabbro, the second Lower Zone is a consistent remobilised zone of massive sulphide mineralisation, in part associated with the 500 Fault. Both zones are well defined by the drilling and the interpretation is considered sufficiently robust for resource modelling. Additional minor mineralised zones include 5 domains in the hanging wall position to the Upper Zone and a minor mineralized sub-vertical fault.

The Savannah North mineralisation has been defined over a strike length of approximately 1 kilometre with clear indications from geophysics it could extend over 2km. The Resource relates to an area with a strike length of 1,010m from 5,350mE to 6,360mE and extends from 750m to 1,750m below surface with an average domain thickness of approximately 5 metres.

Summary:

Savannah ore has been successfully treated through a 1Mtpa SAG mill and flotation circuit since commissioning in 2004. The metallurgical nature of the mineral resource in this estimate has not changed. Metallurgical factors are addressed in Ore Reserve conversion. Preliminary testwork conducted on the Savannah North mineralization has indicated that it has identical metallurgical characteristics as the current Savannah mineralisation.
