I think they simply don't have the answer with just the visual core logging and they are waiting to have a fuller picture before they tell us what it is. If they're not accurate with the info they provide they would be doing us an injustice and damage their credibility. They also might have hit fault zones and interesing samples too but don't have the element composition until they get assays back.
