I think Delta may be in the process of doing some DD drilling at Johnsons.

The first picture below is from the M1 area of Yinnetharra. Four drill hole sites are shown. I suspect the two on the left are RC while the two on the right are DD. While disturbances with zero white can be a duster, even when RC holes hit a duster there's usually a stack of green calco bags for a while that creates a "white" trace that disappears when the bags are shifted. If there's no white spoil/bags, the hole is most likely a DD.


At a guess (but it is still a guess), those two new red spots from 15th April and 20th April are Delta putting down a DD drill into the Johnsons target. There could well be a drill rig on the NE one during the 20th flyover.
