Mineralization in contact-metamorphosed cambrosilurian sediments close to Drammens granite (a biotite granite).
The locality is named '5 minutes' because it's only a very short walk to it.
Ufortunately some mineral collectors has vandalized the area, which makes collectors not wished welcome to the area.
