Located about 5 kilometres east of the King Solomon Mine which is marked by a white headframe along the Yalgoo to Morawa Road. There are two pits next to each other; Deflector Central pit and Deflector West Pit. It is the only location on the field which contains significant copper. It is a gold/copper mine with secondary silver.
The ore is hosted by a monotonous sequence of pillowed high magnesium basalts, intruded by dacitic porphyry, dolerite, and dolerite-lamprophyre dykes and exolithic stock, covered partly by lateritized alluvial sediment. The sediment is 2.5 to 10 metres thick.
The gold is contained in 1 to 5 metre wide veins , which dip steeply east and west, within a sub-vertical shear zone trending north-east to south-west for 600 metres. The wallrocks consist of quartz stockwork, and strongly silicified basalt passing abruptly into fine grained basalt. The mineralisation is dominated by biotite-carbonate-pyrite-chlorite.
Below the sediments the oxidised zone goes to 35 metres below the surface of native copper, copper carbonates and silicate minerals. There is then a transition zone of chalcocite and digenite with localised native copper. Lastly a primary zone below 70 metres of pyrite and chalcopyrite, with minor pyrrhotite and chalcocite in the very high grade areas.
Limonite/goethite contains free gold to 45 metres below the surface. Oxide material to 10 metres below the surface is malachite, chrysocolla and limonite/goethite, with minor azurite, cuprite and native copper. The next section is a mixture of oxides, secondary sulphides and primary sulphides 10 to 35 metres below the surface, but mainly containing chalcocite and digenite. Between 35 to 70 metres below the surface is a mixture of secondary and primary sulphides, and below 70 metres the primary sulphides of pyrite, chalcocite, gold, and electrum, the latter sometimes as coarse grains to 5 mms across.
