A gold-copper mine in contact metasomatosed ore in dolomitic marble around a granite intrusion, 75km SE of Pyongyang. Worked in the mid-19th century by the Korean royal family, then in the early 20th century by a succession of different British-Korean-American-Japanese interests. The ores are hosted in boron-rich skarn and marble. The first boron mineral found was ludwigite, by Shannon, an American. Later, two new boron species, kotoite and suanite, were found by a Japanese mineralogist. Kotoite was first found in the wall rock of the "New Ore Body".
