Induced Polarization Prospecting at the Dongjeom Copper Mine

동점광산(銅店鑛山) 동광상(銅鑛床)에 대(對)한 I.P물리탐사(物理探査)

I.P exploration is conducted mainly at the alluvium covered granodiorite stock of the Red Hill area at the Dongjeom coal mine, employing Canadian Mcphar equipments of variable frequencies-domain method along a total of 8.5 survey line. Mineralization zone is found by LP anomalies along the I.P the profile of frequency mode. Comparing with the past drilling data, the cause of each anomly is furthermore identified as copper bearing mineralized zones. As alteration and mineralization cover all over the Red-Hill altered grandiorite, copper bearing sulfide veinlets and strings filled out the fractured and altered zones.
