Formerly: Mine Lac d'Amiante (Lake Asbestos mine; LAB mine; Black Lake mine), Black Lake, Mégantic Co., Québec, Canada
Technically both with the limits of Thetford Mines and Saint-Joseph-de-Coleraine the mine falls mostly within Saint-Joseph-de-Coleraine.
An asbestos mine in serpentinized peridotite, Thetford mines ophiolite complex. Operated by LAB Chrysotile (LAB = Lake Asbestos Bell), this is a huge, inactive open pit mine (closed in 2011). In recent years many labels show "LAB mine" as the locality which reflects the preference of many local collectors.
Also erroneously known as "Black Lake Mine".
