Argyle North Project
The Argyle North Super Project currently comprises three granted Exploration Licence E80/3253 (Argyle North project), E80/4226 (King River) and E80/4229 (Durack Bore) and two pending Exploration Licence applications E80/4371 (Deception Range) and E80/4376 (King River).
Ground gravity and airborne magnetics/radiometric surveys were completed within the Argyle North project area E80/3253 targeting new diamond pipes along the largely-concealed Glenhill Fault which hosts the giant Argyle diamond pipe approximately 20 kilometres to the south of the project area. During the last quarter, inversion modelling of recent geophysical (gravity and airborne magnetic) survey data were conducted by Hawke geophysical consultants. The model results identified seven exploration drilling targets, with a high priority coincident gravity –magnetic drilling target being outlined at Pomona.
Venus drill hole VRC006, drilled into the southern end of the Pomona target in 2007 was terminated at 47 metres in ferruginous fractured quartzite which proved to be geochemically anomalous in Ba, Fe, Ni, Rb, Ti, Y, As, Ca, Co, Cu, K, Li, Mg, Mn, Sc, Sr, V and Zn. The hole was drilled some distance from the newly identified combined gravity-magnetic target so the anomalous results in VRC006 are regarded to be significant, indicating a possible source nearby.
Heritage clearances were obtained from the traditional owners and Department of Indigenous Affairs (DIA) to drill at selected target areas. Geological field investigations were also conducted in November 2010 to confirm the potential target locations for drill testing.
Approvals are being sought to enable drilling of the main targets to be scheduled for April 2011.
