Rox Resources (RXL) and its joint venture partner, Venus Metals (VMC), have received high gold recoveries from preliminary metallurgical testwork at Youanmi.

The Youanmi Gold Project hosts several types of mineralisation. So, to ensure the various styles are accurately represented, the companies collected 81 samples from 32 reverse circulation (RC) drill holes.

The LeachWELL Accelerated Cyanide Leach technique was used to analyse the samples to determine the cyanide-extractable gold.

Pleasingly, results from the oxide, transitional and fresh zones at the Grace prospect included average gold recoveries of 97 per cent, 94 per cent and 95 per cent respectively.

“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,” Managing Director Alex Passmore said.

Plant Zone

Gold recoveries at the Plant Zone averaged 94 per cent within the oxide mineralisation. Transitional and Primary mineralisation are invalid as deeper drilling is required to test transitional and primary ore.

Youanmi South

The Youanmi South area is deeply weather and the oxide zone extends to 80 metres below surface. Gold recoveries at Youanmi South averaged 93 per cent in transitional mineralisation.


Gold recoveries at the Commonwealth prospect averaged 88 per cent in the sampled primary mineralisation. Transitional and oxide mineralisation are not yet tested.

Main Lode

The Main Lode contains extensive gold mineralisation over a strike length of 2.3 kilometres. The gold lodes are associated with a high pyrite and arsenopyrite content in the primary ore is partially refractory.

Gold recoveries averaged 94 per cent in oxide mineralisation, 80 per cent in transitional mineralisation and 76 per cent in primary mineralisation.


These outcomes will feed into Rox’s ongoing exploration activities and will contribute to its broader understanding of the Youanmi project area.

The promising exploration results delivered at Youanmi over the last 12 months, the new styles of mineralisation, and results presented today have reshaped the perspective of Youanmi as a highly prospective project with non-refractory mineralisation occurring outside the mine area.

Further metallurgical test work is ongoing. Simultaneously, Rox is continuing to drill the Grace prospect, with two RC drill rigs currently on site.

Company shares are up 5.95 per cent and are trading for 8.9 cents each at 11:12 am AEST.
