En rekke forekomster/skjerp ligger fra sørvestenden av Reisjåvannet og sørover opp mot fjellet Raudnuten langs Damdalen. Koordinatene er angitt til hovedforekomsten som ligger opp mot toppen av fjellet. Den ble trolig drevet av Skibdalen Kobberverk (1645-53). Den består av en relativt stor, N-S orientert dagskjæring som ender i en mindre fyrsatt stoll i sør. Den ligger på toppen av et bratt stup. Kvartsittisk bergart dominerer i veggene. Foliasjonen i kvartsitten er 2º/85º Den fører smale (dm-skala) mørke bånd som kan representere mafiske ganger. Driften har fulgt to parallelle, undulerende skjærsoner med kvartslinser og malakittfarging. Disse har svakt fall mot øst og avstanden mellom dem er ca. 2 m. Finkornet kobberglans og bornitt opptrer i grovkornet kvarts.

Dette er en mindre dagskjæring som ligger på vestsida av traktorstien. Den ble utsprenget i 1910 i et gammelt skjerp. Innerst i skjæringa finnes strukturløs, finkornet, grågrønn kvartsittisk bergart med svak kobberglans disseminasjon. Få uregelmessige kvartslinser er vanlig. Tippen er brukt i traktorstien.

503557 6623824 Dette er et mindre skjerp hvor det er skutt ut 2x2 m på østsida av en liten kolle. En mindre skjærsone med kvartslinser og svak kobbermineralisering er observert. Vertsbergarten er finkornet og kvartsittisk.

503849 6624721 En 8 m lang, 1-2 m bred og opptil 1,2 m høy dagskjæring med retning 190º er skutt ut i en grønnlig grå kvartsittisk sandstein. Enkelte kvartslinser og en finkornet amfibolittisk biotitt-førende gang finnes. Finkornet kobberglans er anriket i epidotrik randsone til kvartslinsene (prøve TE0010.04) og i den kvartsittiske bergarten (TE0010.05).

503893 6624938 Et lite skjerp ligger nede ved kanten av Reisjåvannet. Det er 60-80 cm bredt og 4 m langt. Vertsbergart er den samme kvartsittiske sandstein som i de øvrige skjerpene. Svak kobberglans-bornitt disseminasjon opptrer i kvartslinser i en skjærsone.
