Magnetics & Electromagnetics

Evidence of historic mining prompted the magnetic and electromagnetic investigation of this swath of land that measures approximately 1000 feet in width by 1 mile (5280 feet) in length.

The magnetic and electromagnetic surveys were designed to detect features such as mine air-shafts or mine-dewatering shafts. Used in combination, these methods can detect both ferromagnetic and conductive non-ferromagnetic debris that may be associated with the historic mine workings. Such variations are also caused by changes in geology, soil and rock type, moisture content, as well as metallic debris buried within or upon the soil.
