Rox drilling strikes new gold zone at Youanmi

Special Report: Rox’s ongoing drilling has found a new gold zone about 3km north of the historical Youanmi mine site in Western Australia.
Assays have been received for the first 25 of the 251 holes totalling 11,516m that have been drilled to date. These include the 4m zone grading 15.95 grams per tonne (g/t) gold that identified the new zone.
Rox Resources (ASX:RXL) adds that reverse circulation drilling is also ongoing with continuing results such as 2m at 13.96g/t gold from 114m at Grace North while visible gold has been observed in diamond drilling at the Grace prospect.
“We are pleased to report ongoing strong results from our Youanmi exploration efforts which are continuing at pace,” managing director Alex Passmore said.
“Of particular interest is the newly discovered gold zone 3km north of the Youanmi main mine / historical plant. This may be indicative of a new mineralised structure in the Youanmi granite.”
Assays are currently pending for 17 RC holes totalling 2,600m, 226 aircore holes and nine diamond holes.
Aircore drilling to test new targets to the north of the Youanmi mine area with a focus on the structural corridor and parallel structures within the Youanmi granite is already off to a positive start with the discovery of the new gold zone.
The first part of this program has been completed with early interpretation indicating that the sporadic rotary airblast drilling undertaken by previous operators had failed to penetrate the almost ubiquitous silcrete layer at around 11m vertical depth.
Rox’s aircore holes were generally drilled to blade refusal at 40m to 50m depth. Some holes, particularly in limonitic, quartz-rich structures, extend to 70m to 100m
Anomalous results will be followed-up by RC drilling.
The current RC drill program is focused on the Grace Prospect and is planned to consist of 126 holes and extension of 20 previously drilled RC holes for 16,000m of drilling
To date, 89 holes have been reported on.
Exploratory holes have also been drilled along the mineralised corridor within the Youanmi granite which extends for circa 1.5km to the north of historical mine infrastructure and totals around 2.5km strike length.
Rox has also completed the first phase of diamond drilling which is intended to confirm reliability of RC drilling, determine structural controls on mineralisation and to extend RC holes that failed to reach target depth.
Separately, the company has completed a sub-audio magnetic survey over a 2.5km by 1.5km target area for the primary aim of mapping known gold mineralised structures.
Results of this survey will be interpreted in conjunction with the assay results of the aircore drilling to provide important insight into controls on gold mineralisation.
Rox has also conducted a detailed aeromagnetic survey over a 2.5km by 1.3km area within the Youanmi granite to provide high-quality data and excellent geological detail that’s absent in previous aeromagnetic surveys.
