A recent 200-metre spaced infill Magnetotellurics (MT) and Audio-Magnetotellurics (AMT) traverse over the Princess Royal MT anomalies has confirmed and further delineated the conductive anomalies initially identified in August.
Modelling of the higher resolution data by independent geophysical consultants GeoDiscovery Group has enabled the company to define the three priority targets that warrant drill testing.
Ausmex's Burra project is near the historical copper mining centre of the same name in South Australia's mid-north.
The priority-1 target extends from near surface to depth and is associated with gossanous ferruginous quartz breccia with malachite at the surface.
The priority-2 target lies on the eastern side of the historic Princess Royal working and is associated with a mineralised thrust fault along with the anticlinal contact between the Skillogalee dolomites and the Saddleworth formation.
Executive director and COO Geoff Kidd said: “We are very pleased with the additional definition that our recent close-spaced MT transect has provided, we thank Zonge for their timely fieldwork and GeoDiscovery for their rapid modelling and interpretation of that data.
"The result means that we are on schedule for our drilling program, which will commence in the first week of December."
No previous deep drilling has been completed under the secondary copper-gold mineralisation at Princess Royal.
A 2,000-metre reverse circulation program is scheduled to begin the first week of December to test the anomalies.
