Wouldn't your city be on the opposite side of the mountain range? I don't know what scale this is in, but it seems like a fair distance.

Well, based on the scale provided there's about 100 miles as the crow flies between us, and I'd see mining could easily be that far out that's only a two day horse ride. Which is well within the City's reach in a setting such as this. I've no problem with your nation! But I'd sort of assumed mining rights :lol and thus it surely wouldn't be missed, yano the giant evil skelton army.
