Simply prohibiting non-clustered industries can produce maps with only a couple coal or iron mines, if the first mine is on an island or town density is low.
Suggested fix (once I get a development computer running again): when a proposed mine is not within a cluster, compare number of mines to number of forests (perhaps minus 10 or /2). If there are an unusually low number of coal mines, allow construction despite the failed cluster check. If things are normal, deny construction as usual.
