Historic Data Assisting In Gold Mineralisation Search In Western Australia
Enterprise Metals Limited (ASX: ENT) has identified a significant chargeability anomaly through a recently completed 3D-IP survey along the Ausrox Shear zone just east of the Mandilla Homestead in Western Australia.
Chargeability anomalies are generally associated with pyrite content in fresh rock. This survey was focussed over the north-south striking Ausrox Shear, which was highlighted by Enterprise’s 2020 aircore drilling programme.
Enterprise’s target at Mandilla is primary gold mineralisation, similar to that discovered on the western margin of the Mandilla Syenite by Anglo Australian Resources NL at Mandilla East and South between 2006 and 2021. AAR’s drilling has demonstrated that low grade gold intersections in saprolite overly primary gold mineralisation.
Enterprise has located and digitised 40 year old IP data and projected it over the 2021 3D-IP survey, which confirms the validity of the chargeability anomaly over the Aurox Shear zone. Newmont surrendered the Mandilla area without drill testing the IP anomaly.
The company is now planning further drilling with a larger capacity drill rig to follow up the IP chargeability anomaly and coincident gold/arsenic anomalism discovered to date within the saprolitic clay zones along the Ausrox Shear.
The Mandilla Prospect is located in the northern Widgiemooltha greenstone belt in the western part of the Kalgoorlie geological domain, some 100 km south of Kalgoorlie by road and 20 km south west of Kambalda.
Significant nickel and gold deposits are present in the belt, the nearest gold deposit being the high-grade Wattle Dam Mine located approximately 3 kilometres to the west of Mandilla.
