The contemporary history of the Pueblo Viejo gold mine, which produces gold oxide at the top and gold sulfide at the bottom, begins in 1975 with Rosario Resources Corporation, a company that later passed into the hands of the Dominican State under the name Rosario Dominicana, and whose operations ceased permanently in 1999 because of economic and environmental factors.
Historia ya miongo ya karibuni ya machimbo ya dhahabu ya Pueblo Viejo,ambayo hutoa oksidi ya dhahabu kwa upande wa juu na sulfidi ya dhahabu kwa upande wa chini, inaanzia mwaka 1975 chini ya Shirika la Maliasili la Rosario, kampuni ambayo hapo baadaye ilikuja kumilikiwa na Dola la Dominika chini ya jina la Rosario Dominicana, ambapo shughuli zake zilisitishwa moja kwa moja mnamo mwaka 1999 kwa sababu za kiuchumi na kimazingira.
