Persgardshalla Cu-Au mineralisering. IP-målinger og geologi Steinkjer, Nord-Trøndelag.

Abstract:
Rapporten beskriver resultatene fra geofysiske- og geologiske undersøkelser av Persgardshalla Cu-Au mineralisering ved Binde i Steinkjer kommune. Undersøkelsene har vist at mineraliseringene ved Persgardhalla er helt lokale kobber-gull-anrikninger uten noen økonomisk interesse. Det er ingen antydning til andre gullanrikninger i området. IP-målingene tyder ikke på noen ut- bredelse av sulfidmineraliseringer av betydning langs N-S strukturer. De IP- anomaliene som er registrert er trolig relatert til Ø-V strykende, lag- formige Fe-sulfiddisseminasjoner uten noen edelmetall- eller basemetall- anrikning.
