Overall I treat resources popping up as a random event. A nice treat when it happens. No point beelining IW on the basis of a resource might pop up. Chances are you might of found iron anyway.
On last game I had 64 mine and copper popped up around T174 or so. Unclear if stats treats 64 as worked mines or built mines.
