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.

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.
