I don't recall saying I thought Moblan was a bad decision or they paid too much (maybe I did and forgot), it was just a surprising aquisition at the time when there were arguably better value tenements at the time - Frontier and Sigma as you highlighted.

But yes, we have to assume Brett knew or at least was very confident that Moblan was a sleeping monster. Otherwise, as you say, he'll be crucified. The Moblan DFS/PFS will be a very interesting read as well as hopefully shedding some light on those surrounding tenements. As you say, it HAS to be huge...
