And? I'm currently mining helium and I can't check when salt appears, but it does. Well, yes, the gap is big and what? Man, I've been mining helium for two months now and I still can't buy the first upgrade, my village can be dumped somewhere after 8-10 months of play (it won't make any sense before), my damn statue is being built for two weeks! One statue! And only an eighth out of ten, and the construction time doubles every time. That is, only the statues will take almost two months in total. And here you are lamenting the fact that your salt is being extracted too slowly :) Be patient! You were warned from the very beginning that it would take a long time :)
