Controlled Source Audio-Frequency Magnetotellurics ("CSAMT") is a ground based high resolution electromagnetic sounding remote sensing tool which is designed to expand to depth and to determine the ultimate size of the mostly pediment covered, highly aurific Capgold epithermal system.
Phase 1 will consist of TAMT (transient audio-frequency magneto-telluric) surveys on a reconnaissance-level 800x400 metre grid.
Vertical components of this primary field contain transient random impulses of energy varying across a wide frequency range including in the audio-frequency range.
