I believe the holes drilled to date were to determine the formation types and it’s direction within the geological settings. Initially, core samples taken to date will help determine the next holes including future depths. Yes, drilling cost money but no need to go deeper without fully comprehending the geology. IMO, drilling program to date seems very structured so far. We may see drills going deeper in next few holes.

If I was to speculate without seing the cores it is obvious to me that formations are complex which means expect something else along lithium.
