Abstract

Electrical resistivity, self-potential and time-domain induced polarization methods were conducted for study of electrical responses on vein-type sulfides ore, which is intruding limestone and dolomite of Ordovician, of Geumpung mine located in Dojeon-ri, Susan-myeon, Jecheon-si, Chungbuk. Sulfides bearing chalcopyrite, pyrrhotite and galena etc. are deposited in disseminated or vein-type. Good result that resistivity and self-potential surveys detect high grade-estimated mineralized zone located in upper part of existing low grade ore zone is acquisited and is to some extent consistent with induced polarization. Furthmore, a new mineralization zone directing EW is detected.
