From the release:

Drilling at our AT12 target has resumed following a review of new geophysical survey data which indicated a strong target sub-parallel to previous drilling. This suggests that the original drilling may have been improperly oriented to intersect the zone. Lack of down hole survey data from the original AT-12 drilling has introduced a level of complexity to the interpretation of the AT-12 results. Recently, directional surveys have been completed on critical holes in the AT 12 area to assist in the interpretation of the drilling and BHEM. The new drilling will test the target at right angles to the trend of the interpreted anomaly.

This will be very interesting to watch.
