A locality discovered around 1935 by Boliden AB while prospecting for gold. Kautsky (1936) describes this locality as nr. 6 and 6a.
The mineralisations occur as disseminations and semi-massive veins (1-10 mm) of arsenopyrite as farcture fillings and networks in a 200 m long and 1-3 m wide shear zone in granite. Abundatly occurring stilbite/calcite veins in the shear zone most likely post-date the arsenopyrite mineralisations.
Three analyzed samples showed gold values of 205 to 525 ppb.
The NGU report lists two sub-localities:
Stupkanten: 65.2464990,12.9135660
Kraterputten: 65.2459170,12.9104010
