Blika gullgruve (Bleka gullgruve), Svartdal, Seljord, Telemark, Norge


Located near Blika farm (Bleka farm) in Svartdal. About 20 gold bearing chlorite-tourmaline-calcite quartz-veins is known within this deposit. The longest vein 900 m long, 0.3 - 0.5 m wide, surrounded by gabbro.

Was mined by the french company Compagnie Française des Mines de Bamble 1882-1901 and later by A/S Bleka Gruber 1933-1940, thereafter only prospecting was done. Since reserves turned out to be low, the mine was finally abandoned.

Dons (1963) locality nr. 389.
