That's the town they had to move due to mining, wasn't it? I hope this doesn't mean they have to move it again :)
Who needs dowsing rods when you can just move a town and see where it goes to find the next big deposit.
Haha yeah, like Chief White Halfoat in Catch 22
Just follow that town and buy the biggest parking lots you can find
Shouldn't have to, the rare earth minerals are in an area already designated for iron extraction. The new metals are just a nice bonus, I suppose.
I think this deposit is under Mt Luossavaara, which is close to the main iron ore body currently being mined. The old city core is currently being moved and/or torn down anyways, so it shouldn't affect much...
...other than the houses already transferred to the slopes of Luossavaara, I guess. :)
