Why does it seem like management is more concerned about the "causitive source" of the anomaly rather than the anomaly itself?

At the presentation in Calgary, when asked if they drilled the anomaly, she never gave a definitive answer.

At the 27:40 mark, she starts by saying they are drilling the targets as best as possible but have not identified a "causitive source".

Then goes on to say:

28:13

To date the "causitive source" of that anomaly has not been generated, but to generate such an anomaly there has to be something huge there and our initial drill program 1-11 didn't find it. It found narrow veins, which isn't surprising to us, but that's not what we are after. We already know we got narrow veins, we know we have gold, but I want the "source" and we haven't identified that to this date.
