Preliminary metallurgical test work by joint venture partners Rox Resources Limited and Venus Metals Corporation has delivered high gold recoveries from the Youanmi Gold Project in Western Australia.
The Youanmi Project is host to several styles of mineralisation, to ensure adequate representation from the different mineralisation styles. 81 samples were selected for metallurgical test work from 32 RC holes previously reported by Rox across the Project area. Intervals were selected to cover a range of gold grades, mineralisation styles and degree of weathering/oxidation.
Samples were analysed by the LeachWELL Accelerated Cyanide Leach technique to determine the cyanide extractable gold via this industrystandard method and provide an indication of the potential recoveries in standard gold processing circuits.
The results from the oxide, transitional and fresh zones at Grace are exceptionally encouraging with gold recoveries averaging 97, 94 and 95 per cent respectively.
These results indicate that gold mineralisation encountered in recent drilling at the Youanmi Project in general, and especially at Grace, is amenable to conventional cyanide extraction methods.
Rox Resources Managing Director Alex Passmore said the results are in line with their expectations.
“The main lode ore body at Youanmi that was mined historically was renowned as being refractory at depth. This first-pass metallurgical test work demonstrates that different primary mineralisation styles within the Youanmi project area such as the granite-hosted gold at Grace are clearly non-refractory, delivering excellent recoveries with conventional methods.”
