Australian gold and nickel company, Rox Resources Limited (ASX: RXL) has reported further success from the drilling programme undertaken at Youanmi Project in Western Australia
Rox said that all assay results have now been received from recent drilling which focussed on the Grace Prospect and tested several nearby regional targets in similar structural settings.
Managing Director, Alex Passmore, said drilling at Grace continues to define a very high-grade zone of mineralisation (greater than 30 gram-metres) within a broader zone of mineralisation. Significantly, this recent drilling has confirmed a second high-grade zone of mineralization below the discovery zone.
Mr Passmore said the confirmation of this second zone is important as the company interprets Grace to be a series of north-plunging high grade stacked-lodes that lie within a broader zone of mineralisation within fracture zones inside the margin of the Youanmi granite.
Overall, the Grace Prospect shows a ladder vein array geometry. Also, very significantly, at Grace North, some 300m from the Grace discovery hole, RXRC201 intersected a new high-grade gold zone which ended in mineralisation returning 2m @ 18.96g/t Au from 48m.
“Results of the 2020 drilling continue to rapidly advance our understanding of mineralisation at the Grace Prospect, with increasing definition of a pattern of multiple high- grade lodes,” Mr Passmore said.
“Its highly encouraging to see step out drilling identify the same style of mineralisation 300m to the north.”
The Grace Prospect is located within a NNW-trending corridor which includes the Airstrip and Youanmi South prospects. At Grace, gold mineralisation occurs in a series of northerly plunging, stepping lodes within the Youanmi Granite.
Mr Passmore said this style of mineralisation was not previously recognised in the Youanmi area, and features similarities to other granite-hosted gold deposits of the Yilgarn Craton such as Granny Smith and King of the Hills.
Drilling of other prospects nearby tested new areas within the Youanmi Granite. Several holes intersected zones of mineralisation. At Hill End East drill holes RXRC237 and RXRC243 intersected 4m @ 1.6g/t Au from 56m and 4m @ 1.42g/t Au from 56m, with both holes ending in mineralisation. At Plant Zone West RXRC247 intersected 12m @ 1.12g/t Au from 48m. These new results continue to confirm the Company’s view that the Youanmi Granite is highly prospective for gold mineralisation and provide further insight into the regional understanding of the project.
