Gold: There's still more high-grade gold to be found at this historic WA mine

There is still accessible, high-grade gold available at Kingwest Resources’ (ASX:KWR) Menzies gold project in Western Australia’s Eastern Goldfields region if its most recent work is any indication.

Assaying of historical face sampling in the lower levels of the Yunndaga underground workings returned results of up to 31m grading 22.3 grams per tonne (g/t) gold with an average width of 2.1m along Level 21.

Generally, anything above 5g/t is considered high grade.

There is no historical mining at Yunndaga below Level 21 and Kingwest says the results confirm that high-grade mineralisation remains open at depth.

“We are very excited that this data confirms our interpretation and that very high-grade gold mineralisation has not been closed off at the bottom of the Princess May Shoot at Yunndaga,” chief executive officer Ed Turner said.

“There also remain numerous areas also higher up in these mineralised systems that have potential for significant mineralisation to be defined and our review of other historic underground sampling at other deposits including Lady Shenton is yet to be completed.”

The Menzies project recorded historical production of 643,200oz of gold grading 22.5g/t from underground mining between 1895 and 1948 and a further 145,000oz of gold at 2.6g/t from open cut mining between 1995 and 1999.

Meanwhile, Navarre Minerals (ASX:NML) is tapping the brainpower on offer at Australia’s national science agency CSIRO to identify potential sites of gold mineralisation at its Stawell Corridor project in Victoria.

Funding of the collaborative research project will be supported by a grant from the Australian government’s Innovation Connections scheme.

The research project will use supercomputer-based simulations of deformation-fluid flow transport processes involved in the formation of gold deposits.

This is expected to aid exploration by highlighting potential drill targets on the flanks of the Irvine and Langi Logan basalt domes.

Navarre noted that past studies on the nearby 4-million-ounce Magdala gold deposit provided an understanding of the structural history and shape of the basalt, which could be used to estimate the pathways of fluid flow (location of gold mineralisation) around the basalt domes at the time of gold mineralisation.

Coziron Resources (ASX:CZR) has emerged from its voluntary suspension with a new high-grade discovery at its Croydon project in Western Australia.

Drilling at the Top Camp prospect returned a top hit of 1m at 66.1g/t gold from a depth of 141m within a broader zone of 8m at 10.26g/t gold from 135m.

The company says the abundance of intercepts underlying the broad area of surface gold anomalism indicate the potential for a large gold system that includes anomalism extending into the adjacent Middle Camp and Bottom Camp prospects.
