They seem to be concentrating on a 2x2 square kilometre area. They flew VTEM over the property in 2010 and then went back and did an IP survey in 2011. The work from both surveys seemed to identify the 6 strongest anomalies. I assume (but am not sure) these six holes they're planning to drill will hit EACH of these anomalies. Downhole geophysics will tell them if any mineralization is adjacent to or below these areas.
