EXPLORATION - URUGUAY

Uruguay has considerable potential for lode gold mineralization in 3 extensive Proterozoic granite-greenstone terranes that occupy roughly the south-eastern half of the country. The local names for the cratonic terranes are; Piedra Alta, Nico Perez and Cuchilla Dionisio. The terranes are further subdivided into tectonic belts of high deformation and are host to precious and base metal deposits, most importantly; the Isla Cristalina and Don Feliciano belts in the Nico Perez terrane and the Arroyo Grande and La Florida belts in the Piedra Alta Terrane.

The Cretaceous Laguna-Merin basin along the east coast of the country is also considered to have potential for alkaline intrusion related rare earth mineralization and the Rio de la Plata craton along the northern border with Brazil prospective for diamonds.

Orosur has assembled a significant geological, geophysical and geochemical database during more than 10 years of mineral exploration activities in Uruguay. The ongoing exploration activities are funded by strong cash flow and continue generating new opportunities and defining resources for OMI within Uruguay. OMI's exploration programs are supported by an experienced team of geologists and a fleet of company owned diamond and RC drilling rigs.
