Great Western Exploration Ltd (ASX:GTE) is to begin exploration at the Atley Gold Project in Western Australia, with field mapping, soil sampling and shallow auger drilling to test structural targets along strike of the Youanmi and Penny West gold deposits.
Atley is in the Youanmi district, a hotspot for gold exploration following Spectrum Metals' high-grade Penny West discovery now owned by Ramelius Resources Limited (ASX:RMS) and Rox Resources Limited's (ASX:RXL) recent high-grade Grace discovery.
The company has identified six structural gold targets where northwest splays are interpreted to intersect the Youanmi fault and appear to demonstrate similarities to the Youanmi and Penny West gold deposits.
Gold assays up to 21 g/t
Great Western is interpreting gold assays as high as 21 g/t gold in historical drilling in the adjacent Victory Bore prospect as confirmation that the gold fluids are still migrating north along the Youanmi fault past the project area and are a potential source of gold for deposition at structural sites.
While parts of Atley North have been the subject of limited drilling, none of the drilling appears to have targeted these structures.
In addition, there is a 13-kilometre strike of entirely untested Youanmi fault under only shallow cover through the northeast part of the project.
Activities at Atley South will initially comprise field mapping and soil sampling to test the complex structural zone.
Atley South is a structurally complex setting where the Yuinmery fault transitions through a sequence of migmatites and gneiss.
The Yuinmery fault is a large regional fault that terminates on the Youanmi fault and gold mineralisation associated with the fault has been recorded in historical exploration.
There is no record of any previous surface geochemical surveys or drilling and the area appears entirely unexplored for gold or base metals.
A traditional focus on the Youanmi-Sandstone greenstone belt has meant that explorers have not tested the surrounding migmatite terrains.
However, more recently 'significant' gold mineralisation has been discovered in these rock types, such as the Tropicana Gold Deposit.
