A quarry measuring 280x40 m with a depth of 10 m.
Assuming that 40% of all rock taken out could be used, this quarry can have produced about 100.000 tons of microcline feldspar.

Ihlen et al. (2003) assumes that most of the pegmatite has been taken out.

The coordinates are for a spot somewhere in the middle.
