It should be well known by now that private mines aren't yet how they should be.
So... Just spent 150K caps to tell you, that:Private mine bought at SanFrancisco is one square northwest from Redding.Private mine bought at Junktown is on the same squarePrivate mine bought at NCR is two squares south of Redding.You can't buy more than one mine at once and there's a limited amount of minerals in total cost of approx. 60K caps. They're identical, with a shack, cave, table, water pump and NO WORKBENCH. You can't invite anyone and can't make a shared buy. Slaves are able to mine.This folly of mine will satisfy your curiosity and save your money.Thank you for applause...Wait, that was a collective facepalm. Why would you do something like this, developers?
