Skjerpet ligger oppe på snaufjellet i sørskråningen av Gråvola, ca. 300 m vest for Svartåstjønna. Det består av en grop 2.5 x 2.5 m i omriss og 1.5 m dyp. Tippvolumet er omkring 15 kbm. Mineralisering består av mm til 3-4 cm bånd med massiv magnetkis i matriks og bånd av vesentlig gruneritt og kvarts. Desl opptrer mm-store granater. Gruneritt danner typisk rosetter bestående av 1-4 cm nåler. Malmsonen kan følges et titalls meter nordover fra skjerpet og har en mektighet på ca. 0.5 meter. Like øst for hovedsonen er det flere tynne bånd med massiv mineralisering. Sulfidsonene er omgitt av klorittholdig gruneritt-granatbergart med svak, ujevn fordelt impregnasjon av magnetkis. Distalt opptrer mørkegrønn, nærmest monomineralsk kloritt med spredte granater. Mineraliseringen opptrer i pelittisk til semipelittisk kloritt-muskovittskifer, typisk for Åsliformasjonen i Gulagruppen.
