Skjerpet ligger i nordskråningen av en liten, men markert topp, ca. 200 m sør for veien ned til Nesjødammen. Det består av 4x2 m ovalt skjerp som er grunnt og vannfyllt, klassisk fyrsettingshull. En mindre grop med tilsvarende form finnes få meter lengre vest. Øst for hovedskjerpet ligger en mindre tipp (5 m3) med utskeidet malm. Trekullbiter er også vanlig i denne. Gråbergstippen (25 m3) er svært gjengrodd. En 20-30 cm bred malmsone er blottet mellom gropene og i malmtippen dominerer middelskornet, massiv pyrittmalm (prøve .01) med varierende mengde sinkblende (prøve .02). En feltspat+amfibol rik sidebergart, som dels er kvartsittisk er mest vanlig. De to Storvollvola skjerpene (ST0012 og 13) er i ulike malmtyper og demonstrerer også ulike brytningsmetoder.
