High-grade gold hits highlight potential scale of Rox’s Grace prospect

Special Report: The high-grade hits keep coming for Rox Resources at the Grace prospect within its Youanmi project in Western Australia.
Drilling has extended the strike length of the mineralised envelope at Grace to 700m and returned a top intercept of 13m grading 60.49 grams per tonne (g/t) gold from 177m including 4m at 191.56g/t gold from 181m.
To date 76 reverse circulation (RC) holes have been drilled out of the 126 RC holes that Rox Resources (ASX:RXL) plans to drill at the prospect.
Elsewhere on the project, drilling delivered a 3m hit grading 10.26g/t gold from 107m at the Grace North prospect.
“Mineralisation strike length continues to grow as we conduct step out drilling with impressive grades being encountered,” managing director Alex Passmore said.
“With a combination of infill RC and diamond drilling we are well placed to deliver a strong maiden resource for Grace in due course”.
Exploration is also focused along the mineralised corridor within the Youanmi granite, which extends for about 1.5km to the north of historical mine infrastructure and totals around 2.5km strike length.
The northern extent of the mineralised corridor and parallel structures now recognised in the granite are being tested by aircore drilling with potential to extend mineralisation further to the northeast.
While results are pending, early interpretations are that the sporadic rotary air blast drilling by previous operators failed to penetrate an almost ubiquitous silcrete layer at around 11m vertical depth, potentially leaving extensive granite-hosted mineralisation undetected.
This is expected to be addressed by the company’s aircore holes, which extend to between 40m and 50m depth with some in limonitic, quartz-rich structures going beyond 100m.
Rox is also carrying out diamond drilling to better characterise mineralisation at the Grace prospect.
Results from this are pending, however logging of mineralised core intercepts from Grace indicate that gold is hosted within highly altered zones of fractured granite within an overall north-northwest trending structural zone.
