Vistadmoen skjerp befinner seg mellom Rv.38 og Tokke-elva, ca 3 km vest for Dalen sentrum. Hovedskjerpet består av en vannfylt, delvis tilgrodd røskegrøft i kanten av et jorde. Grøfta er ca. 3m lang i nord-sør retning, 1 m dyp og 75 cm bred. Bergarten er grønnstein. Skjerpet er for overgrodd til å se noe mineralisering, men det var enkelte mineraliserte blokker i den overgrodde tipphaugen like ved. I følge blokkene består mineraliseringen av uregelmessige, spredte linser av kobberkis og bornitt i kvarts. Det er skutt litt i en liten skrent 50 m mot sørvest, ca 1x1 m bredt og 1m dypt innhugg. Det er litt malakitt å se i en ca. 10 cm bred sone i veggen. Videre er det en totalt overgrodd røskegrop like ved veien inn til moen. Den er ca. 2.5 m lang i nord-sør retning, 1m dyp og 0.75-1 m bred. Det er ingen mineralisering å se. Forekomsten ble anmeldt av J. Mossige og O. Sønning i 1899 og mutet av G. Gundersen fra Stavanger samme år.

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.
