The project is located in the Eastern Goldfields region, WA. The primary targets are gold and base metal mineralisation within a buried sequence greenstone rocks.
The project is located approximately 50 kilometres north of Leonora and 10 kilometres east of the Teutonic Bore and Jaguar polymetallic copper-zinc-silver (Cu-Zn-Ag) Projects and along a strike to the south east of numerous gold mines including the Celtic, Black Cat and Great Western Gold Mines with more than 300,000 ounces of gold in resources.
Geological Survey of WA has previously mapped the area as granite, with overlying surficial alluvial cover material; however the airborne magnetic data suggests the underlying geology is possibly greenstone lithologies.
Importantly, greenstone lithologies are the host rock of the majority of gold and nickel deposits throughout the Eastern Goldfields region of WA.
Field reconnaissance has located greenstone rocks at the base of a number of old wells across the project area. The greenstone rocks were found on the mullock piles from around the wells, which were hand-dug around the early 1900’s. The estimated depth of the granite – greenstone contact down the wells was 20 – 25 metres. The discovery of the greenstone rocks on the project area supports the interpretation of the airborne magnetic data.
The CSIRO conducted hydrogeochemical sampling of the wells and bores within the area as part of the MERIWA project M402 – Hydrogeochemical Mapping of the Northeast Yilgarn Craton, with the results released in 2009.
Analysis of these results shows that a number of the water bores within the project have elevated mineral chemistry within the water table. One well showed elevated gold and zinc and another has elevated copper, zinc, silver and nickel.
This information further supports the potential of the buried greenstone rocks within the project area to host gold and base metal mineralisation.
