I don't understand why we haven't completed:

1. Aerial surveys over the project area so that we can identify and target these other outcrops
2. Rock chip sampling of these outcrops, as well as the two existing zones (for metallurgical testing)
3. Wide spaced (100m or more) RC holes along the north and south of the defined zones to cheaply determine just how far mineralisation extends along strike under shallow overburden

Can any geos out there shed any light on this?
