MineArchiveMines in Orkney
Orkney's mining history is really a history of quarrying — flagstone and millstone cut from the islands' hard Devonian sandstones since prehistory — with one strange exception: a 1970s discovery of uranium-bearing rock near Stromness that came within a planning decision of becoming Scotland's only working uranium mine, and was stopped by the islanders themselves.
