The Akukan mine (Russian: Рудник Акукан) operated during 1927-1932 for the excavation of muscovite (potash mica).
It was located in the Akukan Ravine north of Baikal Lake, Buryatia, 40 km North-East-East off Nizhneangarsk, 7 km North of the village Kholodnaya (now settlement Kholodnoye, 55°52′57″N 109°45′42″E / 55.88243°N 109.76177°E / 55.88243; 109.76177).
[1] There are documentary indications that to man the mine a Special-Purpose Camp (lager osobogo naznachenia) of OGPU was operated.
The locals refer to the mine site as "the former labor camp".
In the collection "The Beloved Northern Land" compiled by N.K Kiselyova the place is referred to both as a labor camp and a special settlement.
