Forekomsten ligger i vestsiden av en liten ås om lag 10 m øst for traktorvei ved en myr og like før traktorveien går under en kraftlinje. Skjerpet består av en smal, ca. 5 m lang skjæring som er drevet ned langs en ca. 10 cm mektig kvartsåre. Tipphaugen har et volum på bare 10 kbm. Åren er parallell strøket i bergarten som er målt til N354Ø/46. Mineraliseringen består av uregelmessige aggregater av kobberglans og bornitt i kvartsen. Nordrum og Van der Wel (1981) har også funnet kobberkis, wittichenitt, hessitt og hematitt. Omgivende bergart er glimmerskifer. Forekomsten ble mutet av N.P. Søgaard i 1902 og O.O. Sønning i 1923.

Abstract:

The mineral, rock and ore deposits within map-sheet Sauda are described. The most important types are slate and schist, fluorite, and iron-titanium, copper and zinc deposits. Mica, feldspar, soapstone, asbestos, manganese, molybdenum and lead deposits are also present. No significant mining or quarrying activity is in progress at the present time (1978). Most of the occurrences of slate and schist are located within the lower Caledonian thrust zone. The iron-titanium deposits are of magmatic origin and related to mafic intrusives. The fluorite, copper and molybdenum deposits are associated with various stages of hydrothermal activity in Precambrian time. The Sauda zinc deposits occur in metamorphic rocks and have been affected by hydrothermal activity. The lead mineralizations are confined to regions along the eastern border of the Caledonian mountain chain. They are most likely of the same type as the lead deposits occurring along this border elsewhere in Scandinavia.
