The Moolart Well Gold Mine is located within the Duketon Gold Project, approximately 350 kilometres north, north-east of Kalgoorlie in Western Australia. The Company completed development of the Moolart Well Gold Mine in the September 2010 quarter on time and within budget. 
 
The Moolart Well deposit is a large oxide gold deposit sitting within a deeply weathered Archaean ultramafic-mafic volcanic sequence above the base of weathering at about 70m vertical depth. Primary gold-sulphide mineralisation exists within quartz lodes and alteration zones beneath the weathered zone in fresh rock.
 
The deposit consists of two zones: a flat-lying laterite zone developed in an iron-rich weathering hard cap, and a deeper oxide zone developed in clays. These relationships are illustrated in the cross section below.
 
The laterite zone of mineralisation is covered by 6m of barren colluvial material and extends down to an average depth of 20 metres. Over the known 5km x 1.5km extent of the Moolart well mineralisation, the average mineralised laterite ore thickness is 3.8 metres, and the average colluvial cover is 6.4 metres.
 
The oxide mineralisation extends from beneath the laterite cap at 20m down to the base of weathering at approximately 70m vertical depth.

Mining is conducted using truck and shovel excavation methods by Mining and Civil Australia Limited. The plant design is based on a nominal 2.0mtpa throughput utilising a three stage crushing circuit, a scrubber and a single ball mill followed by gravity and carbon in leach circuits.
The Company continues to actively explore within the significant oxide zones to add to the reserve base of the project.
