Forekomsten består av en liten, grunn og trekantformet grop som dels ligger under en rotvelt, nord for ei myr og vest for Sachserhusåsen. En smal kvartsgang, dels med hulromsfyllinger er blottet i nordsida. Den har orientering 212°/80° og fører noe kobberkis, pyritt, sinkblende og blyglans sammen med kullblende. Verstbergarten er en kvartsrik og grågrønn og representerer trolig en omvandlet amfibolitt.

Dette er et litt større skjerp med tipp som utgjør 5 m3 og ligger nord for hovedforekomsten. Det er svært overdekket omkring skjerpet og kun en minst 0,5 m bred kvartsgang med orientering 184/80 er blottet. Vest i denne finnes et 10 cm bredt bånd med tilnærmet massiv pyritt og mindre mengder kobberkis. Kvartsbreksje og anrikninger av kullblende er også observert.
