| Forekomsten ligger øverst i bratt skrent og er lokalt benevnt "Kishølet". Det er sprengt ut en ca. 5 m lang stoll, og en vannfylt skråsjakt sies å være 15 m dyp. Den mineraliserte sonen er ca. 1 m mektig, sterkt foldet, og veksler mellom disseminasjon og semimassive bånd. Tilsvarende mineralisering finnes som <0,5 m mektig lag i vegskjæring ved UTM 608850-7088750. |
