Elizabeth Creek Copper Cobalt Project
The Elizabeth Creek Copper Cobalt Project is centred approximately 30 km south-east of Woomera and 135 km north-west of Port Augusta in South Australia.
The project currently covers 701 km2 in the Olympic Dam Copper Province, Australia’s most productive copper belt. The project is located 100 km south of BHP Billiton’s Olympic Dam copper-gold-uranium mine and 50 km west of OZ Minerals’ Carrapateena copper-gold project.
The project mining centre lies 10 km off the sealed Stuart Highway and is accessed by established unsealed roads. Established access to electrical grid power and scheme water is available in the area. The Adelaide to Perth/Darwin railway runs parallel to the Stuart Highway. Additionally, regular air services are available at Roxby Downs and Port Augusta, and a serviceable airstrip for light aircraft is located on site. Accommodation is available at Woomera.
The MG14 and Windabout copper-cobalt deposits at Elizabeth Creek, are hosted by flat-lying undeformed sedimentary rocks of Late Proterozoic Age, deposited on the Stuart Shelf. These platform sediments are referred to as the ‘Cover Sequence’ and unconformably overlie complexly deformed and metamorphosed igneous rocks of the eastern margin of the Archaean Gawler Craton.
The copper-cobalt-silver mineral deposits are composed of sediment-hosted fine-grained sulphides. Copper is primarily hosted in chalcopyrite, with accessory chalcocite and bornite, with Cobalt is primarily in the form of carrolite.
The main mineralisation occurs as well-defined stratabound zones at the upper and lower contacts of the dolomitic shales and arenites of the host Tapley Hill Formation (THF). The THF appears to have been deposited in shallow basin-like structures elongated along a north-west to south-east trend. Elevated base metal values (copper, lead and zinc) occur throughout the unit, but large-scale economic deposits are rare outside of the Elizabeth Creek area.
RESOURCES AND RESERVES
MG14 & WINDABOUT
The MG14 deposit is a concealed, flat lying body of disseminated copper sulphide mineralisation at 25m depth. It is oriented east-west and is approximately 1,400 m long by 400 m wide with a varying thickness between 3 to 8 m. A JORC 2012 compliant resource was estimated by T. Callaghan in January 2018 with a cut-off grade of 0.5% Cu equivalent.
The Windabout deposit is similar in style to MG14 with copper sulphide mineralisation dipping approximately 5° to the north-east and varying in depth from 55m to 80m. The deposit is elongated east-west and is approximately 2,000 m long by 1,000m wide with varying thickness between 3 to 8 metres. A JORC 2012 compliant resource was estimated by T. Callaghan in January 2018 with a cut-off grade of 0.5% Cu equivalent.
MG14 deposit has a JORC 2012 compliant indicated resource estimate as follows 
|CuEq > 0.5% cut off
|CuEq > 1.0% cut-off
The Windabout deposit has a JORC 2012 compliant indicated resource estimate as follows 
|CuEq > 0.5% cut off
|CuEq > 1.0% cut-off
The currently contemplated mining strategy for MG14 and Windabout mineral deposits is based on the shallow depth, free dig overburden, and their sheet-like and sub-horizontal structure. The MG14 orebody would likely be mined first due to its higher grades and shallow depth while Windabout, with a lower head grade, longer life, and higher stripping ratio would likely be mined subsequently.
The Emmie Bluff prospect in the north of the Elizabeth Creek project area is comprised of the same style of Tapley hosted Cu-Co-Ag mineralisation style as is found at MG14 and Windabout. Emmie Bluff is an underground target, with the top of mineralisation sitting at approximately 400m.
Much like the other deposits, the host rock is largely flat lying, extending over an area of roughly 3km by 2km, with mineralisation split into an upper and lower lode at the Tapley Hill’s contact horizons.
The company has recently defined a significant JORC 2012 compliant maiden Mineral Resource Estimate (MRE) at Emmie Bluff, demonstrating the enormous scale of the deposit, which is one of the largest known of its type in Australia.
The Emmie Bluff JORC 2012 compliant mineral resource estimate is as follows
