Two pegmatite quarries in a 140 m long and 60 m wide pegmatite (Ihlen 2001), at the north-eastern margin of the Lauvrak mining area.
A check on the altitude map suggests that this pegmatite might actually be closer to 250 m long.
The coordinates are given for the northern quarry.
Ihlen writes that there two quarries, while the altitude maps shows three:
58.54941°N 8.42939°Ø
58.5484°N 8.42878°Ø
