EXPLORATION - CHILE

OVERVIEW

Pantanillo, is an advanced stage exploration project. It is a gold porphyry deposit located in the well established and well mineralized Maricunga Belt in Region III, Chile . The Maricunga Belt has seen a marked increase in exploration and gold production over the past five years, with defined resources in the region now totaling over 60 million ounces of gold in no less than half a dozen projects. Pantanillo is located directly between Kinross Gold's Maricunga Mine (Ex Refugio) and the Marte-Lobo project.

The second property, Anillo is focused on early stage epithermal Au+Ag vein project located within the Paleocene Belt of the Region II, in northern Chile. The project lies directly north of Yamana's El Peñon Mine, and to the west of the Escondida Mine.

In 2011 Orosur acquired the Talca property, located 375 km North of Santiago in the Region IV of Northern Chile, covering an area of 2,000 hectares. Talca mine has been operated by artisanal miners for 40 years and has produced an estimated 300,000 oz of gold from a system of 7 high grade veins. Grades between 10-20 g/t Au have been reported and visible gold is common. Principal structural control is NNW (320° - 350°) trending shear zones and faults structures traced from four to eight kilometers along strike. Historical mining on NNW structure was over 2-4 m widths of high grade. Inspection of underground access across structure shows potential for wider mineralized zones.
