Most of the work reflected in this report is based on a geochemical and geological survey conducted by the Korean International Cooperation Agency (KOICA) and the Korean Institute of Geology, Mining, and Materials (KIGAM) in 1998.
The ore deposits in the east and east central Guatemala are generally divided into three types of deposits:
1.Vein type of gold-silver and lead-zinc deposits widely distributed in volcanic and granite intrusives especially in the southern part of Motagua fault zone;
2.Nickel-chromium deposits associated with ultramafic serpentinite and peridotite rocks in the middle part of Guatemala; and
3.Antimony and polymetallic ore deposits related with Tertiary rock which is exposed in the regions of mid-Tertiary volcanic activity.
The present report compiles the existing information on the Izabal District and the La Unión Area, south of the Izabal Lake. It shows the gold potential of several targets in the region.
