Passive airborne EM and Ground IP\Resistivity results over the Romero intermediate sulphidation epithermal gold deposits, Dominican Republic

The Romero gold copper zinc silver deposits are located in the Province of San Juan, Dominican Republic, approximately 165 km west-northwest of Santo Domingo. Romero and Romero South orebodies contain stratabound gold mineralization with copper, silver and zinc of intermediate sulphidation epithermal style. The gold mineralization is associated with disseminated to semi-massive sulphides, sulphide veinlets and quartz-sulphides within quartz-pyrite, quartz-illite-pyrite and illite-chlorite-pyrite alteration.

Helicopter AFMAG (ZTEM™) and aeromagnetic survey results over epithermal gold and gold-skarn deposits in the Guerrero Gold Belt, Mexico

ZTEM™ helicopter electromagnetic and aeromagnetic surveys were flown for epithermal gold and gold-skarn targets on the Aurea Norte Property in the Guerrero Gold Belt. Survey results supported by 2D-3D EM and magnetic inversions indicate that the Ana Paula mafic intrusive hosted epithermal style gold deposit features high magnetics and low resistivity at depth; whereas San Luis oxidized skarn-style deposit hosts weak magnetics with high resistivity at depth. Both trends appear to be influenced by NS regional structural controls.

Predicted lithological map of the Iullemmeden basin

Integrating airborne geophysics with Landsat TM imagery and geology for assessing the mineral potential of the Iullemmeden Basin, Niger.

Airborne geophysical surveys, consisting of fixed-wing magnetic gradiometer and gamma-ray spectrometer and helicopter-borne full-waveform Versatile Time-Domain Electromagnetic (VTEM™) surveys were carried out over the Iullemmeden basin, in western Niger for mineral exploration and detailed geological mapping
