| First time registered 1899. The main ore body consists of a minimum 50m long EW running rusted zone of 3-4m thickness in medium grained gabbro, 570m above sea level. The mineralization consists of a comparatively weak impregnation of pyrrhotite and traces of chalcopyrite and pentlandite in fine to medium grained gabbro (sample 02). Comprised in the mineralized zone is a 0.5m thick lense of non-mineralized gabbro, with sharp contacts. The mineralization bears marks of several pit mining attempts. The first pit in the NNE at 640m a.s.l. is located in an about 10m thick rusty zone with pyrrhotite impregnation and minor chalcopyrite and pentlandite in medium grained gabbro (sample 01). Locally, sharp but irregular contacts with non-mineralized gabbro occur. The mineralization continues for another 100m towards SE until 690m a.s.l.. A second mineralization of similar type crops out in the middle one of three creeks at 540m a.s.l.. A third rusted zone is visible 100m over this one. |

| Rapporten er delt i 3 bind: Bind IB Bilag, Bind II plansjer nr. 01-12, Bind III Plansjer nr. 13-36 samt liste over bilag nr. 37-80 som ikke er vedlagt rapporten, men som finnes i NGU's arkiv. Rapporten er meget omfattende hva bilag angår, men synes i ettertid ikke å være noen sluttrapport over alle de arbeidene som ble utført under oppdrag 555. |

| Abstract: | |
| I 1961 ble det bestemt å iverksette regionale malmundersøkelser over kyststrøket Vest-Finnmark - Nord-Troms. Som ledd i dette program søker en å lokalisere de malmforekomster og mineraliserte soner som måtte finnes i distriktet og på denne måte få avgrenset områder for mer detaljerte undersøkelser. Listen omfatter 180 anmeldinger av i alt 427 punkter. |

| Skjerp 1 (spor etter skjerpevirksomhet) ligger mot NNØ, 640 m.o.h., i en omlag 10 m mektig rustsone som fører impregnasjon av magnetkis og spor av kobberkis og pentlanditt i middelskornet gabbro (01). Stedvis sees skarpe, men uregelmessige kontakter til umineralisert gabbro. Mineraliseringen fortsetter vel 100 m SØ-over til 690 m.o.h. |

| Mineralisering 2 har utgående i den midterste av tre elver, 540 m.o.h. Det er et lignende, relativt svakt sulfidimpregnert bånd. Nok en rustsone sees ca. 100 m over denne. |
