Mineraliseringen ble første gang anmeldt i 1897. Røskingen foregikk sannsynligvis i 1898. Mineraliseringen har utgående 70 m høyere enn veien i Manndalen og er fulgt fra Kjerringdalselva og 90 m sørover med 8 små skjerp i en skrent. Mineraliseringen ligger i finkornet amfibolholdig glimmerskifer. 1-2 m over mineraliseringen er det amfibolittlinser i glimmerskiferen. Mineraliseringen, hovedsaklig magnetkis med mindre mengder kobberkis, er knyttet til en skjær- og breksjesone i skiferen hvori også opptrer en kvartsgang som fører mm-mektige biotittskiferlag. Det er tre malmtyper i mineraliseringen: Finkornet, massiv po-cpy-sl-malm med små granater, opptil 2-3 cm store kvartsboller og litt biotitt (prøve 01). Middelskornet, massiv po med litt cpy og sl, rik på biotittskiferfragmenter og enkelte kvartsøyne (prøve 02). Hydrotermalkvarts med po-cpy-sl-innfylling (prøve 03). Hvordan disse opptrer i forhold til hverandre kan ikke sies pga. liten blotningsgrad. Største observerte mektighet av massivmalm er 70 cm. Den konkordante kvartsgangen er opptil 1,2 m mektig (i nordenden).

Abstract:

The report gives the results of a 4-year (1952-55) programme for the investigation of a former copper-mining area in the north of Norway, carried out by the Geological Survey of Norway (NGU). The stratigraphy and structure of the district have been discribed in a previous NGU publication (Padget 1955). The ore deposits occur in one particular division (Ankerlia Series) of the layered Caledonian schists which underlie the whole area (see Plates 1 and 2). No deposits have been found outside this division. The greatest concentration of deposits occurs in the centre area along the south limb of a major, open E-W anticline (Moskogaissa anticline). In the same area the normally NW-plunging linear structures of the schists show a marked swing to an E-W direction (Plate 2). It is suggested that this area of "structural anomaly" has been responsible for the concentration of the sulphides. However, all kinds of control have been relatively weak and nowhere have the orebodies reached significant size by modern standards. It appears that the ore-bearing solutions spread out over large areas along zones of minor shearing within the Ankerlia Series. These zones lie roughly concordant with the schistosity and bedding for the schists and manifest themselves at outcrop as bands of marked rusting which are easy to follow in the field.

	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 området for mer detaljerte undersøkelser. Listen omfatter 213 anmeldinger av i alt 979 punkter.
