| Skjerpet er 4x4 m. Det er overgrodd og mektigheten av den mineraliserte sonen kan ikke bedømmes. Bergarten er en finkornet kalkspatmarmor som er gjennomsatt av uregelmessige kvartsårer og -seggregasjoner. Sidesten er en kalkholdig muskovitt-biotittskifer. Marmoren fører disseminasjon og uregelmessige årer av sinkblende, blyglans, svovelkis og kobberkis (prøve 01 og 02). UTM 477570 7358210: Skjerp i samme mineraliserte horisont. Er ikke befart. Mineraliseringen befinner seg på samme nivå som Malmhaug Pb-Zn. |
