Name(s) in local language(s):
Yxsjögruvan, Yxsjöfältet, Ljusnarsberg, Västmanland, Sverige


Tegengren (1924) mention Yxsjöberg as a copper-tungsten- deposit discovered in the year of 1728. Four claims exist (1924); Norra & Södra Yxsjögruvornas, Kvarnåsgruvan and Dammgruvan, but Källgruvan, Bolagsgruvan, Kärrgruvan, Gäddan, Ricco, Åkergruvan, Nävergruvan, Kvarnåsgruvan and Norra Kärrgruvan are as well mentioned in the text (gruva= mine).
Intermittently mined depending of the copper price.

During WW I the mines became interesting again due to the tungsten and fluorite grades. A processing plant was quickly built but already in 1920 the mines closed due to the low market prices.

The mine reopened in 1936 and a new plant was built. Fluorite concentrate started to be produced in 1956. Due to falling tungsten prices the mine closed in 1963 and became water-filled.

AB Statsgruvor bought the property in -69 and production restarted in -72. Mining ceased again in the summer of 1989 due to falling W-prices.

Output in 1984 was 160,000 tons of fluorspar. Mining was done by sub-level stoping & cut-and-fill mining procedures. Workings are at least 600 meters deep.
