Ok found where they were drilling. The DD reference was depth drilling. Charger appear to not yet be drilling any of the new rock chip based targets on the map below.
9 Feb. As per below, there's no new drilling out to the west or SW.
There are a few new drill holes in the southern extent of the existing pattern. As at the end of December
As at 9 Feb I can see two new holes circled in blue as at 9 Feb. There may also have been some DD extension to the holes about 10-11 O'clock just outside the blue circle but in terms of new drill pads its only a couple. Typically pure DD drilling doesn't give a good Sentinel signature so you can't really tell if they hit something useful or useless from the images.
If put on the same map, Medcalf is in the top right. TG6s' Burmeister in the bottom left.
