Forekomsten ligger ca. 170 m nord for Fiskumelva og det er lett atkomst via gårdsvei fra Smebrua. Det er drevet en røskegrøft ca. 10 m lang, 2 m bred og 1.5 m dyp og en vannfylt grop 4.5 m lang, 2.5 m bred og 1.5 m dyp ca. 25 m mot nord-nordøst. Ca. 25 m vest for grøfta er et lite pegmatittbrudd (se BU 0030 i industrimineraldatabasen). Skjerpene er drevet på en kvartsbreksje sone som er steiltstående og har retning mot NNØ (016 grader). Sonen er ca. 2 m bred og består av drusekvarts. Sulfider er tilknyttet seinere kvartsårer som gjennomskjærer en tidligere kvarts-karbon mineralisering. Kvartsen er typisk i kamstruktur, mens sulfidene sitter typisk i randsonen av strukturen. Sulfider er vesentlig pyritt og sinkblende med underordnet kobberkis og blyglans, samt et lysegrått mineral som sannsynligvis er arsenkis. |
