Almost monomineral ic clinochlore is mined at the Golden Antler mine, about 40 km southeast of Butte, Montana, in the Silver Star district, a district where gold, silver, copper, and lead were formerly mined. The chlorite mine is in the SWI/4 sec. 14, T2S, R6W, in Madison County and is leased by Cyprus Industrial Minerals Company. The author identified clinochlore from this deposit in 1975, and open-pit mining on a small scale began in 1977 (Berg, 1983). The light-colored and high-grade nature of the clinochlore from this deposit allows it to be used in some of the same applications as talc. The present note reports the physical and chemical properties of this unusual chlorite mineral.
