Forekomsten ligger 100 m vest for Store Damtjørn. En bilvei går fram til den gamle setra Vestkvammen. Det er rapportert om mindre forsøksdrift i 1910 på gamle skjerp med senere undersøkelser i 1919-20. En 8 m lang og 1-1,5 m bred dagskjæring med retning 60º er drevet. Fin- til middelskornet amfibolitt med foliasjon 15º/50º opptrer i veggene. Disseminasjon og strenger av kobberkis+bornitt finnes i amfibolitten som dels er noe anriket på feltspat. Mineraliseringene er ubetydelige.

513893 6611015 I dette området finnes to mindre skjerp og en liten dagskjæring. Skjerpet i nord har vegger på 2x4 m og amfibolitt er blottet. I ei lita grop vest for dette forekommer kobbermineralisert kvartsårer/-linser som er opptil 5-6 m brede. Bornitt som danner strenger og aggregater i grovkornet kvarts dominerer (prøve TE0014.02). I tillegg finnes amfibollinser i kvartsen. Ca. 30 m lengre sør er det en dagskjæring på vestsida av en skrent. Disseminasjon og strenger av bornitt+kobberglans forekommer i plagioklas-rik amfibolitt (TE0014.03).
