East Musgrave Block, South Australia
(GOLDSEARCH 49%)
The East Musgrave Block tenements cover parts of the highly prospective Giles Complex, Proterozoic rocks and its interpreted extension into the eastern Musgrave Block in South Australia. Significantly limited drilling by Kennecott in the early 1970's at Tuckerbox Hill (held under ELA 343/96) intercepted disseminated nickel-copper sulphides in one of three shallow holes completed. The nickel-copper sulphide mineralisation consisted of up to 5% pyrrhotite-chalcopyrite-pentlandite-pyrite over a downhole width of approximately six metres adjacent to the southern margin of a major dyke. The Tuckerbox dyke is a differentiated mafic to ultramafic dyke complex with mapped dimensions of approximately 15 kilometres in length by 150 metres in width. The Tuckerbox dyke and other associated Giles Complex intrusives are considered excellent targets for magmatic nickel-copper deposits.
The East Musgrave Project is a joint venture between Goldsearch and Independence Group NL.
The project covers approximately 16,000 square kilometers. All tenements and applictions currently lie within the Anangu Pintjantjatjara Yankunytjatjara freehold aboriginal lands.
Regional geochemical sampling and gravity geophysical surveys have been completed over prioritised areas within the two granted tenements. This work has defined a total of ten target areas for further evaluation. The two highest priority targets have been selected for further evaluation using ground elctromagnetic (EM) geophysical surveying, with the aim of identifying conductive nickel sulphides in the subsurface. These programs commenced in September 2009 and, if suitable targets are generated, drilling is scheduled for early in 2010.
