Abstract

Three groups of Au deposits and occurrences have been distinguished. The first comprises Lower Cretaceous ores, including Pueblo Viejo and several uneconomic showings in the El Valle area; comparison of the acid-sulphate hydrothermal system of Pueblo Viejo with the disseminated, single-stage El Valle system accounts for the differences in tonnages and grades. The second group is formed of Upper Cretaceous barite-polymetallic (Cu-Zn)-Au-Ag epithermal ores in the NW Dominican Republic and Haiti; Cu-Mo anomalies in the oxidation zones are consistent with the observed presence of Cu-Mo porphyries at depth. The third group comprises Upper Cretaceous to Tertiary metasediment-hosted, metamorphic quartz-sulphide, granitic vein swarms of the Miches area, the probable source of the Miches lateritic/alluvial gold. Leaching tests of samples from El Valle and Restauracion have demonstrated the viability of routes such as thiocyanate leaching., Three groups of Au deposits and occurrences have been distinguished.
