Tanco Mine - Wikipedia
The pegmatite ore body now mined by the Tanco Mine was discovered in the late 1920s and the first mining started in 1929. Several times the mine was closed, reopened and closed, until in 1969 when it was reopened as a tantalum mine. Cabot Corporation bought the mine in 1993, and began the production of caesium brine from pollucite in 1996.
