Andersen (1931) reports that from several small quarries a total of up to 300 tons of feldspar has been mined many years ago.

There is a problem with the name of these quarries. Andersen designated the nickname Rumpetrollskjerpet to Landsverk 2.

This was an unfortunate choice, since the actual bog by that name, is located closer to Landsverk 3 than 2.

There have been trials to mine for molybdenite, probably without much success.

On the altitude map, it is clear to see that there were three larger quarries (still very small) and several prospects.

It has been said by Jarl Verhagen (per. com. 15-11-2018) that Gunnar Nordbø many years ago had found samples of chrysoberyl in one of these quarries.

Gunnar Nordbø being an active and knowledgeable collector, this might actually be true.

Since it is known exactly which one, the larger quarries are listed separately.

At the altitude map, it is also visible that Landsverk 2 and 4 are very likely situated in the same pegmatite, which would then be an about 500 m long and 30-100 m wide dike.

Nowadays these quarries are part of the Evje Mineralsti, a fee-collecting site, and paying visitors are allowed to dig here as much as they like.

The (suspected) prospects can be found at:

58.5977°N 7.86196°Ø

58.59726°N 7.8625°Ø
