Feb 05, 2009· Gold-Ore Resources Ltd. announces that the Board of Directors has approved an underground mine expansion plan for the -owned Bjorkdal Gold Mine in Sweden. The mine is currently producing gold at the rate of 40,000 ounces per annum and the planned expansion will, over the next few months, raise gold output levels by approximately 20%.
The gold at Björkdalsgruvan 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 Skellefteå Group. The veins mainly trend NE and NNE and terminate at the sediment-intrusive contact.
The Björkdal gold deposit is a lode-style, sheeted vein deposit that is hosted within the upper-portions of the Skellefteå Group lithologies as they are found at Björkdal (as described above). Gold is found within quartz-veins that range in thickness from less than a few centimetres in width, to over several decimetres in width.
Björkdal Depth Extension Since September 2020, a major focus of exploration at Björkdal has been on the depth and eastern extension of the Lake Zone veining. This veining sits beneath the marble unit, below and to the south of the Aurora Zone.

Jan 03, 2008· Bjorkdal does do a 1-week shutdown every year for scheduled maintenance. The comparison to Troilus is reinforced in the mill. Bjorkdal takes 79% of its gold out of two gravity circuits, a high-grade one producing a 50%-gold concentrate and a medium-grade one that runs 1,500 grams per tonne.
