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 sasa ya mgodi wa dhahabu wa Pueblo Viejo, unaotokeza oksidi ya dhahabu kwenye sehemu ya juu na ya dhahabu iliyo chini, huanza katika 1975 na Shirika la Maliasili la Rosario, kampuni ambayo baadaye iliingiza ndani ya Serikali ya Dominika chini ya jina Rosario Dominikaa, na ambayo utendaji wayo ulikoma kabisa katika 1999 kwa sababu ya mambo ya kiuchumi na kimazingira.
