Skjerpet ligger på toppen av en mindre kolle vel 200 m nord for Honsvannveien. Det består av en mindre utsprengt grop. Flere subparallelle kvartsårer med orientering omkring 210-220°/70-80° er blottet i en båndet hornblende-førende gneis. I nordvest finnes fin- til middelskornet amfibolitt. Mineraliseringen består av bånd og aggregater av sinkblende i dels båndet kvarts, samt blyglans langs kontakten av kvarts. Lokalt finnes hulromsfyllinger i kvartsen og kvartsbreksje. Mineraliseringene likner BU0205 Aspesæter.
