One of the oldest feldspar quarries in Evje.
Bjørlykke locality nr 108.
The mine and mine dumps are open to public collecting for a fee (see general information on Landsverk).
The pegmatite dyke is about 20-30 m wide and about 120 m long, strike E-W and dip nearly vertical.
Bernd Gautestad, son of Theodor Gautestad, who once exploited the Landsverk 1 quarry, is of a different opinion. Observations from the old days seem to indicate that the pegmatite is not a vertical dyke, but rather dips at a 45-degree angle into western direction. (Personal communication to Ronald Werner, August 2017)

Note to the mineralist:

Gadolinite and thortveitite specimens were traditionally labelled with only "Landsverk" as locality name. It is almost 100% certain that in all cases thortveitite originated from Landsverk 3, and gadolinite from either Landsverk 3 or one of the neighbouring quarries.

Davidite-(Ce) was also only labelled with "Landsverk", and might actually come from Landsverk 3 or any of the other quarries in the area.

Pyrrhotite has been found in other pegmatites in the Evje-Iveland pegmatite field, but it has been said that it is more likely in the case of Landsverk 1, that it was ore from the Flåt nickel mine, that fell off the cableway while being transported to the smelter in Evje.

Laumontite was reported in old literature (Schei 1905), but a modern confirmation is lacking. In the collection of the Evje og Hornnes geomuseum Fennefoss there is no laumontite. What actually has been found, also in recent times, are epimorphs/pseudomorphs of a mix of albite/microcline/chlorite after a mineral that by crystal shape actually might have been laumontite. The perimorphs/pseudomorphs form long prismatic "tubes", sometimes empty, sometimes filled with the above-mentioned mix. The end termination is a single plane at an angle that corresponds pretty well with laumontite.
