TURAIR: A recent development in semi-airborne electromagnetic prospecting

Abstract

The applicability of airborne electromagnetic methods to base-metal exploration has been well established by a success record of discovery spanning two decades. Such methods have been restricted by: (a) Their useful depth of exploration; (b) Limited penetration of weathered overburden; (c) Dependence upon topographical relief and/or high tree growth. The Turair method comprising fixed energising source with airborne receiver system greatly enhances the depth of penetration, penetration of conductive overburden and less dependence on topography, with only a limited effect on mobility.
