Sorry for second post but just thought if want to ramp tension & keep game length could take a leaf out of the AIs book though some people probably will not like it.

Sometimes it seeds an area with random single mines, often a sensible area as in units fairly near or approach to a ford etc. A 10x10 area 100 hexes might have none or 2-6 so low chance of finding but once do follow the leader becomes important. Can improve chances of running into by putting the odd one in nice locations to attack units that are suseptable to fire at range.
