The Km 88 Au Area constitutes an important concentration of metals, essentially gold, copper and molybdenum located in The El Dorado - Km 88 greenstone belt of southern Bolivar State, Venezuela and is closely associated with the intersections of major tectonic lineaments. The El Dorado - Km 88 greenstone belt covers more than 20,000 square kilometers in southern Venezuela, and together with the El Callao greenstone belt contains one of the largest gold reserves in South America. The metallogenic setting is within a thick metamorphosed volcano-sedimentary sequence affected regionally by numerous granitoid intrusions. The areas showing economic mineralization are characterized by various stages of sericitization, tourmalinization and argillic alteration closely associated with the intersections of large northeast and northwest trending regional deep-seated lineaments.
