| Det er utsprengt noen få m3 fra mineralisering i en skrent i vannkanten til bruk som ballastmateriale for båt. Den finkornige kvartsbåndete magnetittmalmen (prøve 02 og 04) er 3 m mektig. Den inneholder noe magnetkis og kobberkis som disseminasjon og som mobilisat på sprekker. Stedvis på enkelte sprekker opptrer molybdenglans (prøve 03). Prøve 01 er knakkprøve over mineraliseringen (gjennomsnitt). Mineraliseringen er muligens sammenhengende med Sennvatnmineraliseringen. |
