Björkdalsgruvan, Sandfors, Västerbotten
1988-99 the largest gold mine in Europe. Closed for a short period (around millenium) when the Terra Mining AB went bankcrupt.
The gold at Bjorkdal is associated with centimetre to metre wide subvertical quartz veins within a biotite-altered granodiorite. The gold mineralization is localized near the contact between the intrusive and the overlying Skelleftea Group. The veins mainly trend NE and NNE and terminate at the sediment-intrusive contact. The gold is found both as free milling gold and also associated with pyrite.
OP& UG operation since autumn 2007.
Today owned by Gold Ore Resources.
Located approximately 40 km from Skellefteå.
