Abstract

Email to a Friend
Airborne and ground magnetic surveys were made over and in the vicinity of the Sanford Hill ore body at Tahawus, Essex County, New York. These geophysical surveys served to: l. delineate, lithologic and structural features associated with the ore bodies; 2. indicate a major extension of the Sanford Hill ore body; and 3. guide a drilling program to prove this extension. The titaniferous magnetite ore body at Sanford Hill is associated with gabbro occurring in anorthosite. The contrast in the magnetic susceptibilities of these rock types, reflected in the magnetic measurements, allows geologic-mapping showing rock types and inferred structural features. The anomalous magnetic high of the airborne magnetometer survey indicated a southern extension of the Sanford Hill ore body. Diamond drilling, guided by the airborne and specifically the ground magnetic results, substantiated this interpreted ore extension to be of major magnitude.
