I really like this quote from the article -

Cripple Creek is a diatreme complex, much like the one we have at Rattlesnake. The diatreme at Cripple Creek is about 3 km wide and about 6 or 7 km long. Our diatreme complex is about 4 km long and about 1 to 3 km wide. Rattlesnake Hills is not quite as big but it’s still very sizable. Keep in mind that we are at a very early stage here; Cripple Creek has had about 120 years mining history where we’ve had 2 years drilling. If you compare it in terms of its vertical extent and the footprint of the size of the system, it is comparable.

Always before (in my recollection) they were careful to qualify that the similarities to Cripple Creek were in terms of geology, rather than size of deposit. This is the first I've seen which anyone comes right out and says the deposits may be of comparable size. The confidence just seems to be oozing from Quinton in the last couple of interviews.
