| Det antas at røsking er foretatt samtidig som i Kong Oscar, men tidsrommet er usikkert. Mineraliseringen er trolig strukturelt anriket pga. tildels intens folding. En enkeltanalyse i Nilsens rapport av en knakkprøve fra området inneholder 0.28 % Cu, 2.00 % Pb, 2.44 % Zn, 7.5 ppm Ag og 0.12 ppm Au. Stien, R. 1993. Forekomsten ble forsøkt befart m.h.p. prøvetaking i 1994, men ble ikke funnet. Tross oversiktlig terreng, lyktes det ikke å lokalisere noe skjerp her, heller ingen rustsoner. Forekomsten kan ikke ligge på de oppgitte koordinater. Furuhaug, L. 1994. |
