About the timeline, if I recall correctly someone mentioned that DF had 20 drills at VB (many more than Noront has even if Noront has faster drills) so they would be delineating the mineral resource faster. Also, the ovoid is a massive deposit that, by itself, is many times larger than DE1. As we all know, DE has tremendous potential, but unless Noront discovers a single deposit that is comparable in size to the ovoid, then it may well take significantly longer than 18 months to prove up enough resources to place it in the same category as VB.
