It could be simple: a mine= a school or an Hospital. If mining societies weren't so stupidly greedy, they should get aware it could help a lot of people, and that way, maybe they won't be bothered by local maffia and maybe, if offering a new quality of life, maybe they could prospect in zones they weren't welcome. Mozambique, for example, needs everything, after last year hurricanes. Nobody, not Romans neither Portuguese, dug for gold, because it was founded in alluvial sands.
