Ved denne lokaliteten er det skjerpet to steder: et sydvestlig og et nordøstlig skjerp. Man finner begge skjerpene ved å gå mot syd langs kysten fra Salthella. Det sydvestlige skjerpet ligger på østsiden av en liten N-S-gående høyderygg, skjerpet er vannfylt (0.5 m dypt) og det er utskjerpet 8-10 m3. Sulfidsonen er orientert 0°/78°Ø, den kan følges 7-8 m og tykkelsen er opp til ca. 60 cm. Det nordøstlige skjerpet ligger 20-30 m NØ for det ovennevnte. Her er det utskjerpet 3-4 m3. Sulfidsonens orientering er usikker, men etter rustimpregneringen av den gabbroide vertsbergarten å dømme er orienteringen N-S. Mellom disse to skjerpene ses 2 rustsoner, hvorav den ene har litt massiv magnetkismalm. Litt syd for skjerpene ses flere mindre rustsoner med enkelte magnetkiskorn. Litt pentlanditt er observert i polerprøver, og mineraliseringen er likvid-magmatisk.
