Rox belts out its winning gold hit at Youanmi

Special Report: Rox Resources has intersected exceptional gold grades with visible gold from surface while drilling at its Youanmi gold project.
It is a sight that every gold explorer longs to see, plentiful little nuggets of gold that can be clearly seen in the chip samples recovered from the drill hole.
That Rox Resources (ASX:RXL) has just this result from surface at its OYG joint venture – part of its Youanmi gold project in Western Australia – makes the result all that much sweeter.
The gold was seen in a hole at the northern-most line of the drill plan with assays returning a bonanza intersection of 5m grading 125.68 grams per tonne (g/t) gold from surface, including 2m at 311.46g/t gold from a depth of 2.5m.
Contained within this was is a half-metre intersection that clocks in at an eye-watering 1058.49g/t, or about 37 ounces, of gold.
This is well above the 5g/t result that is typically considered to be high-grade.
Rox noted that while the reverse circulation drill chips from this intersection are weathered, the host rock appears to be granite with abundant vein quartz.
This led the company to interpret that the gold is from a primary source rather than from supergene upgrading.
“We are very pleased to report these high-grade results and look forward to reporting further results from drill testing down dip and to the north of this position,” managing director Alex Passmore said.
The company added that while exploration was still at an early stage, historical mine records indicated that there was reportedly free-milling gold mineralisation present within the Youanmi granite to the east of the Main Lode Shear Zone.
Free milling ore readily allows gold to be extracted using simple processes that do not require chemicals such as cyanide.
One such area is a gold lode developed in the footwall to the Main Lode, towards the northern end of the Main pit.
Historical records from before 1942 describe this as the Peru Reef, a narrow sub-vertical north-trending quartz vein with a mineralised strike length of about 100m.
While production figures were not recorded, the grade is reputed to have averaged more than 60g/t gold from near surface workings.
Rox plans to drill a series of holes to test the north-northwest strike and deeper potential of this bonanza hit.
Thanks to the shallow nature of the mineralisation, the company will also dig a series of costeans – trenches or small pits – across the interpreted strike to assist in geological mapping and to provide channel samples for assay.
