Forekomsten ligger like sørvest for E6, ved gården Gryteng innerst i Kåfjorden ved innkjørselen til Mattisdalen. I en bratt skråning er det slått inn to korte stoller og skjerpet en del langs en ca. 100 m lang sone. Virksomheten har ifølge opplysninger i Alten Copper Works arkiver foregått i den første perioden av gruvedrifta i Kåfjord, antagelig på 1830-tallet. Forekomsten har aldri vært i drift. Mineraliseringen opptrer i en breksje i den nedre massive delen av en dolomitt tilhørende Storviknesformasjonen. Røskearbeidene antyder at mineraliseringene må ha vært små, rundt 1 x 2 m, flekkvis fordelt langs sonen. Et nettverk av rekrystallisert dolomitt og sulfider ligger i en lys dolomitt som opptrer med diffus avgrensning mot den vanlige, massive, rødlige dolomitten. Den lyse dolomitten inneholder bruddstykker av chert. Breksjen avgrenses i hengen av skifer og bedre laminert dolomitt. Mineraliseringen som består av bornitt med mindre mengder digenitt, kobberglans, covellin og kobberkis, er ujevn og opptrer som et årenett i de rekrystalliserte dolomittsonene og som fortrengning av dolomitten. En del mineralisering opptrer på tynne stikk utenfor breksjen. |
