I lived for six months in a town called Leinster, a company town 1000km from the nearest major city (Perth, Australia). It was run to support a nickel mine, back before FIFO (fly in, fly out) rosters were commonplace and everyone lived in the city.

Interesting place. You weren't supposed to drink the water so people would go to town and get distilled water (though I was at school and we just drank from the water fountains connected to mains water). In general though it had much better facilities than similar towns of that size due to being funded by the mining company.

Wikipedia says it still has about 700 people - though I believe the town was shut for several years while the mine was in care and maintenance (the nickel price is not high enough to justify mining at the time so they operate on barebones staff doing equiment maintenance and dewatering) - and by the sounds of things that is happening again now so I'm not sure what it's like.
