Project Highlights 

The 45.6km2 Viper Project comprises a single granted EL located 8km northeast of the wheatbelt town of Jerramungup and centred on the historic Netty Copper Mine within granites, felsic to mafic granulites, dolerite and gneiss of the Archean Lake Grace Terrane (Figure 5). EMU has recently applied for an additional EL covering 76.9 km2 to the immediate south.

Past production from Netty over the period 1907 – 1969 is reported at 3.13 tonnes of contained copper from 30.5t of oxide and sulphide (chalcopyrite) ore at a grade of over 10% Cu.

Detailed channel sampling of the underground mine workings over a strike length of 40m by Audax Resources Limited in 1987 returned copper values in the range 3% to 10% with a peak value of 14.1% from a total of 52 samples. Nickel results were mostly over 1,000 ppm, with a peak value of 0.51%.

Netty is interpreted by EMU as a discrete occurrence within a broader base metal trend associated with shearing at the contact of a mafic intrusion (dolerite dyke) with Archean granite. This setting has not been previously evaluated by any systematic exploration. 

Emu’s initial exploration program will focus on the geochemical assessment of the Netty mine and host trend by auger soil geochemistry. Detailed ground magnetics will assist in delineating fault controls to the mineralisation in conjunction with IP geophysics to explore for disseminated sulphides at depth. Follow-up drill testing of the priority geochemical and geophysical targets will be carried out as required.
