They won't do a JORC until they do another round of drilling, infill or otherwise so IMO it is too early to estimate resource size...Even if I could I wouldn't be able to explain it to you since you state you are only a TA guy and have no idea what any of the companies you invest in actually do...
Hylea also has about 8 km along strike with highly anomalous targets that also need to be drilled...
There is always the possibility of multiple companies in a nearology situation sharing the cost of a mill/refinery...I actually expect this to happen here or there..Not saying necessarily with Hylea..All IMO of course..
