 In 1954, Robert M. Reininger took over leadership of the 75-year-old New York and Honduras Rosario Mining Company, which then held only one old, depleted gold mine and a small new startup mine, El Mochito, in Honduras.From these limited resources, Reininger built Rosario into a powerful and diversified mining and oil company, with interests stretching out to North America, South America, and the North Sea.Under Reininger's leadership, El Mochito, with its rich ore and spectacular wire silver, soon became Central America's largest precious and base metals producer.
