Fra Reisadalen er det anlagt ca. 7 km kjerrevei gjennom Moskodalen inn til restene av smelteverket, som ligger nede i dalbunnen 360 m.o.h. Herfra går det skinnegang mot sør oppover fjellsida til gruva som ligger 710 m.o.h. Forekomsten ble funnet rundt 1900. Drift var igang i årene 1904-07 ved et svensk selskap, Nautanen Kobberverk, som eksporterte ca. 1700 tonn skeidemalm. Birtavarre Kobberverk reiste et lite smelteverk og gjenopptok driften i 1917 og drev ett år. Siste driftsperiode var 1929-30 da malmen ble smeltet til skjærsten og skipet som sådan. Gruven produserte ca. 40 000 tonn råmalm med gjennomsnittlig 2.7 % Cu. "Gruven er drevet med stoller mot sør, anlagt på en stokkformet fortykning av malmleiet. Malmstokken har akseretning ØNØ-VSV og et fall av ca. 1.5° mot ØNØ. Den største påviste bredde er ca. 100 m og lengde 170-200 m. Mektigheten er vekslende. Et kompakt lag bestående av magnetkis og kobberkis har en mektighet som varierer fra 0.5 til 1.5 m og fører fra 3 til 4 % Cu. I heng og ligg opptrer tynne striper med rik erts og lag med impregnasjonsmalm. Den malmførende sone varierer i mektighet fra 4 m og opp til 10 m. Mot vest er forekomsten gjennomsatt av en forkastning med retning N-S. Forekomstens vestlige del ligger lavere enn den østlige, idet man har en spranghøyde på ca. 15 m. Forekomstens vestlige fortsettelse er påvist ved et diamantborhull inni gruven, hvorved man i et dyp av 10 m nådde malmen som her var 4.8 m mektig med 2.67 % Cu" (Poulsen 1950). " Den pretektonske, premetamorfe stratiforme magnetkis-kobberkis-sinkblende-mineraliseringen opptrer i en grågrønn, finkornet kvartsrik hornblendeskifer i hengen av Girjegaisaamfibolitten. Den pyrittfrie, sinkblendeførende magnetkis-kobberkis-mineraliseringen kan skilles i 3 malmtyper: 1. Breksjemalm: sidesteinsfragmenter fra cm- til m-størrelse flyter i massiv sulfidmalm, 2. Massivmalm uten breksjefragmenter, og 3. Impregnasjonsmalm: Fra sterk til svak sulfidimpregnasjon i ligg- og hengbergart, samt sprekkefyllinger og mindre sulfidlinser". (Kleine-Hering 1973)

Short report on the Moskodalen copper mines.

;Norges geologiske undersøkelse;FAGRAPPORT;Bergarkivet; No.BA 898;7 pages

Abstract:

This report describes the location, history, geology and ore, and detailed description of the Moskodalen Mine. An estimate of the ore reserve is based on field observations, two adit levels, and a diamond drill hole. The mine has yielded 40 000 tons ore with 1068 tons Cu. The remaining ore in estimated at 185 000 tons with 4950 tons copper.

Abstract:

Rapporten er en utredning om malmressursene ved Moskodalens gruver og beskriver kort områdets geologi og malmmineralisering. Videre blir gruvens drift og malmberegninger behandlet. Det blir anbefalt nye undersøkelser som i hovedsak består av opprensking og driving av en ny stoll.
