Duck Creek Project

The Duck Creek project consists of 6 EPMs and 20 mining leases (ML), covering a combined area of 278sqkm centred approximately 35km southwest of Cloncurry. The project area can be accessed from Cloncurry by sealed roads. The Townville-Mt Isa railway line runs through the project area in the east.


Duck Creek project tenement location

The regional structure is dominated by the Duck Creek anticline and related NW, NE and near E-W striking faults and shear zones. The local stratigraphy is characterized by the Early Proterzoic Argilla Formaiton quartzite and felsic volcanics, through Mid Proterzoic Marraba metabasalt and amphibolite to Mitakoodi quartzite of the Malbon Group. Of particular importance is the Marraba metabasalt and metadoloerite unit, which hosts most of the known copper-gold mineralization in the Duck Creek area.

The style of mineralisation in the Duck Creek area is characterized by cuperous sulphide quartz veins, breccia veins and disseminated alteration zones. The width of mineralisation and alteration zones is from a few metres to several tens of metres whilst the length is from a few hundreds of metres to more than 1 kilometre. The mineral assemblage is relatively simple and dominated by quartz, chlorite, pyrite, chalcopyrite, malachite, azurite and chalcocite etc.. Wall rock alteration is mainly silicification, chloritisation and minor K-feldspar veining.

Preliminary exploration undertaken by QMC has indicated that the Duck Creek area has potential to host significant copper sulphide mineralization under the thin cover and/or at depth. Encouraging results include

36m @ 2.66% Cu, 0.23g/t Au and 238ppm Co from 198m including
8m @ 5.23% Cu, 0.38g/t Au and 716ppm Co in the Horseshoe prospect

plus several untested strong copper-gold geochemical anomalies.
