THE DRILL SERGEANT: Rox Resources (ASX: RXL) completed preliminary metallurgical test work at the company’s Youanmi gold project Joint Venture with Venus Metals (ASX: VMC).
Rox Resources reported the testwork delivered high gold recoveries from the Youanmi gold project.
Because the Youanmi project is host to several styles of mineralisation and to ensure adequate representation from the different mineralisation styles, the JV collected 81 samples for metallurgical test work from 32 RC holes previously reported by Rox across the project area.
Intervals to be tested were selected to cover a range of gold grades, mineralisation styles and degree of weathering/oxidation and were then analysed by the LeachWELL Accelerated Cyanide Leach technique to determine the cyanide extractable gold via this industry-standard method and provide an indication of the potential recoveries in standard gold processing circuits (i.e. CIL).
The JV determined the results from the oxide, transitional and fresh zones at Grace to be encouraging with gold recoveries averaging 97 per cent, 94 per cent and 95 per cent respectively.
Rox considers 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.
“We are very pleased with these results, which are in line with our expectations,” Rox Resources managing director Alex Passmore said in the company’s announcement to the Australian Securities Exchange.
“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.”
