Ann: Drill Programme commences at Wattle Dam Gold Mine, page-14

There is gold through out the area and stock work etc. Just because there is minor low-grade ore below the mined out ore body doesn't necessarily mean that the ore body extension must lie below. The shear zone, if it has indeed truncated the main ore body, would have separated the upper and lower section of the ore body. The lower section has been moved somewhere else, see their current theory, and other rock will have replaced where the ore body once was with a small amount of gold in it.

Anyway, hopefully they have a positive outcome on testing their hypothesis.
