The deposit is located in the steep slope down from the road, right before the bridge at Lysefjordbrua on the E side of the fjord at circa 30m above sea level. An 8m long ladder is suitable for descending the last few meters down. The deposit consists of two pits at the same height in the terrane, about 10m apart. The NW one is 4m long and runs 3m into the rock face. The entrance is 2m high. The pit in the SW is a little larger and better exposed to study the geology. The country rock characterizes as coarse grained granitic gneiss with a few dm-sized lenticular layers/bands of hornblenditic rock, possibly representing dolerite dikes best studied in fresh road cuts. In the SW pit, sulphide ore occurs as a 10-30cm wide lense of almost massive pyrrhotite with minor chalcopyrite (sample 01) running 4-5m along the strike towards SW. The matrix mainly consists of hornblende and apatite. The ore zone runs parallel to the underlying gneiss (210/025) and is overlain by a 10-40cm thick amphibolite. The same gneiss continues upward. The ore zone and the amphibolite form pinch-and-swell lenses in the gneiss. The thickness of the ore zone in the NE pit is 10-30cm, whereas it is only a few cm wide between both pits. Apparently, extraction has occurred where the ore zone was thickest. A sample (02) of the massive pyrrhotite from the small tailings heap shows a somewhat elevated copper content.

Det vestre skjerpet ligger ca. 20 m vest for det sørvestre innslaget til hovedforekomsten. Det består av et 1 m langt og 2 m høyt innslag som faller inn mot nord. Trolig er det en mindre skråsynk som nå er vannfylt. Mineraliseringene er like og opptrer på samme tektonostratigrafiske nivå som i hovedforekomsten. Tilnærmet massiv magnetkis opptrer sammen med amfibolitt i granittisk gneis. I den østre veggen er den totale mektige på magnetkismalm og amfibolitt ca. 90 cm, mens i vestveggen kiler både amfibolitten og malmen ut. Der er kontakten mot den granittiske gneisen breksjert med fragmenter av biotittisert amfibolitt. Malmsona består av tilnærmet massiv magnetkis+pyritt+kobberkis i apatitt-rik matriks (prøve .03) som omslutter uregelmessige amfibolittlinser. Kontakten mellom dem er dels skarp, men sulfidene kan også fingre inn i amfibolitten (.04). Tilsvarende stikk og årer med sulfider finnes også i den granittiske gneisen i vestveggen (.05) og i stuffer på tippen (.06). Amfibolitten er 60-80 cm mektig og kun svakt sulfidmineralisert mellom forekomstene.
