Australian Silica Quartz (ASX: ASQ) has obtained further promising gold assay results from recent drilling at its Koolyanobbing Metals Project (KMP) in Western Australia.

The results confirmed significant near-surface high-grade gold mineralisation at KMP, where Australian Silica completed a 16-hole reverse circulation (RC) drilling program in September for 1,479 metres in length.

Drilling was undertaken to test two well-defined late-time, fixed-loop electromagnetic conductors and several high-priority gold targets within the Golden Wishbone Gold Trend.

Multiple commodities

The KMP comprises 320 sq km of granted tenure lease areas including overlying portions of the Koolyanobbing Shear Zone and Koolyanobbing Greenstone Belt.

It was established by Australian Silica in 2022 by combining existing tenements with those acquired from Netley Minerals.

While the KMP is considered prospective for gold, silica, nickel and lithium, it is gold that has been prominent in recent exploration activities at the project.

Golden Wishbone

Work to date has assessed that Golden Wishbone is a gold-in-soil anomaly with a 650m strike-length lying at the northern end of an 8km gold trend.

The target covers the abandoned 1930s Golden Wishbone mine shaft, with reported production of 204 ounces from 344 tonnes giving an average grade of 18 grams per tonne from a single quartz vein.

Australian Silica completed a four-hole, 413m RC program at Golden Wishbone during September to test the central part of the target and is currently planning to undertake further drilling by way of a close-spaced aircore program to test the extent of gold mineralisation, which is open along strike and down dip.

EMU target

Australian Silica also completed a nine-hole RC drilling program totalling 716m at the EMU prospect during September.

That program tested three sections, with the highest-grade intercept previously reported as 8.0m at 0.7g/t gold from 60m including 4.0m at 1.1g/t gold from 64m.

The company believes that gold and pathfinder anomalism in surface sampling and structural interpretation of magnetic data both indicate that mineralisation remains open in three directions and is now planning to undertake additional drilling to further delineate these zones.
