Gold and base metals exploration company Golden State Mining Limited (ASX: GSM) has received the go-ahead” for drill testing of four gold target areas at Yule South in Western Australia’s Pilbara Region.
Managing Director, Michael Moore, said the four gold target areas show anomalous gold and pathfinder alteration vectors with follow up RC drilling to test bedrock responses to these significant and anomalous gold intersections.
Based on positive field studies, a decision was taken to expand the RC drilling programme from 1,500m to 4,000m to accommodate additional targets with prospective geochemistry.
We’re pleased to have now received regulatory approval for the planned 4000m RC drilling programme at Yule South across four priority gold target areas,” Mr Moore said.
“These interpreted intrusive style targets, which delivered encouraging first pass anomalies will now be assessed by probing RC drilling to gauge their gold potential.
“The Company has just over 700 sq. km of tenements now granted at Yule and this gives the company a strategic ground position within the Mallina Basin.”
The targets to be tested are:
Target 1 West
Significant silica and pyrite alteration has been recorded in addition to multiple intersections of anomalous 0.1g/t gold values at this target. These indicators are interpreted as a potential mineralised intrusive at depth.
Target 1 East
Magnetic inversion modelling has an interpreted anticlinal intrusive feature which has not been tested by AC blade drilling. Interpreted structural zones outlined by magnetic linear features occur either side of this modelled intrusive which host several gold intersections recorded in Phase 1 AC drilling.
Petrological work suggests that the mafic package recorded between altered granitoid intrusions (refer to ASX announcement dated 23 September 2020) has been subject to silicification with patchy sericite and pyrite alteration. This target also recorded anomalous gold intercepts and zones of significant magnetite and leucoxene alteration.
Phase 1 AC drilling outlined a 1400 long metre arsenic anomaly reinforced by two +0.1g/t gold drill intersections. Subsequent AC drilling confirmed the strong arsenic anomaly and widespread smoky quartz and tourmaline vein development with associated pyrite-chlorite-sericite alteration suggesting a potentially significant mineralised system at depth.
