If the plan is to sell or JV, which seems to be the case and is fine by me, then I agree that drilling some deeper holes makes sense.

These guys don't throw money around, so I find it very encouraging that they have already identified locations where they think it's worth giving it a go. The deeper angled holes at C3 were described as "follow up", presumably after the XRF guns had worked their magic on the earlier holes. Exciting stuff!

Carbonatites sound like tricky beasts that have multi-elemental potential, even beyond REEs, so I'm very keen to see what's going on a bit deeper down and would rather not wait a decade for that. C6 is also very interesting because being 25km off to the side I assume that it may have formed under conditions slightly (or perhaps not so slightly) different from C2-5 and may therefore contain its own distinct advent calendar of goodies.
