Moolart Well.
Moolart Well is a blind gold deposit with several styles of gold occurring within the regolith profile. In transported regolith extending to 20m depth, a laterite zone is defined by a coherent subhorizontal gold blanket consisting of colluvial ironstone and pisolites in a clayey iron rich matrix. The laterite zone has an average thickness of 4m, extends over 5km N-S and 1km E-W and in some areas extends within 2m of the surface.

Below the laterite zone in the residual regolith is the oxide zone extending from 20m to 70m vertical depth with a similar lateral extent to the laterite zone.

Oxide mineralisation consists of numerous primary moderate to steep 60° east dipping gold bearing structures preserved in the clay rich residual profile and sub-horizontal supergene gold developed in the lower part of the profile. Host rocks for the oxide zone are a sequence of moderate to steep east dipping archaean mafic rocks, including basalt and dolerite sills, and ultramafic flow sequence, intruded by late stage high level diorite and quartz-diorite sills and dykes.

Gloster.
Gold mineralisation at Gloster is within a NW- SE trending, NE dipping shear zone and associated with flat to moderately NE dipping quartz veins hosted in intermediate intrusives. A 5m transported cover sequence conceals the gold mineralisation and weathering extends up to 100m depth. Intensive gold leaching has occurred in the uppermost 15m of the weathering profile.

The mining method assumed in the Ore Reserve study is the same as that currently employed at the Moolart Well Gold Mine and the Gloster Gold Mine, which utilises drill and blast, excavator and truck open pit mining. The existing pit has been designed to be developed in a series of progressive cutbacks.

Duketon North Operations (“DNO”) comprises the Moolart Well, Gloster, Dogbolter, Petra and Anchor pits with all ore processed through the Moolart Well processing plant.

The Group has two reportable segments which comprise the Duketon Gold Project; being Duketon North Operations (“DNO”), currently comprising Moolart Well and Gloster and Duketon South Operations (“DSO”), currently incorporating Garden Well, Rosemont and Erlistoun. A number of new mining operations at satellite pits will commence in the next several years. In addition to Moolart Well and Gloster, DNO will include Dogbolter, Petra and Anchor pits as all will be processed through the Moolart Well processing plant. DSO will add Baneygo and Tooheys Well and the other satellite projects in that area to the Garden Well leaching circuit.
