RUN embarked on an iterative process of reviewing and interpreting it’s extensive airborne geophysical data to determine if a ‘fingerprint’ of the INCA deposit could be identified in the complex magnetic structure at INCA. The goal was to use that fingerprint to identify other magnetic anomalies for targeted reconnaissance drilling. This work has led to DYL’s geophysical consultants Resource Potentials (Perth) identifying ten priority INCA-Type (IT) targets (IT-1 to IT-10 in Figure below) based on the geophysical signature (‘fingerprint’) of INCA.
Target IT-3, located 3 kilometres southwest of INCA was selected as the first drill target as it was on a continuation of the INCA ‘magnetic unit’ along a magnetic feature through the previously drilled INCA South Prospect located 1 kilometre southwest of INCA. Drillhole INCR388 at target area IT-3 returned an intercept of 11 metres at 1,064 ppm eU3O8 from 84 metres (ASX 17 November 2010). INCA South was drilled as a reconnaissance target in 2008 as an initial test of the extension of uranium mineralisation based on magnetics, and, as previously reported, vertical diamond drillhole INCD15 intersected 27 metres at 1,471 ppm cU3O8 from 39 metres depth.
Note: The background image is a Tilt Derivative (TDR) processed image which shows the horizontal width of the magnetic zone as well as its intensity using the usual convention of white-red as high to dark blue-purple as low.
Target IT-3 has now been renamed INCA FS (Far South) as detailed in the Development Section.
