| Mineraliseringen er tilsvarende den i Krakadalen (NO0600), og ligger sannsynligvis på omtrent samme nivå. Skjerpet er 7x1 m og delvis gjengrodd. Over ca. 0.5 m mektighet er det opptil 15 cm brede kvartsittlinser med sulfidmineralisering, hovedsaklig sinkblende, svovelkis og blyglans (prøve 01 og 02). |

| Abstract: | |
| Rapporten beskriver en dags befaring av to sinkmalmskjerp. Malmen er striper eller impregnasjon av sinkblende og kobberkis. Sideberget er kalkstein og glimmerskifer. |
