  Orosur Mining: Golden Prospects in Chile and Uruguay

  David Fowler, Director & CEO of Orosur Mining, talks about acquiring a well known artisanal gold mine in Chile

  David Fowler, Director & CEO of Orosur Mining, talks about reducing the cash cost of gold production, a resource update for a satellite deposit, acquiring a well known artisanal gold mine in Chile, a run of mine heap leach project in the Maricunga gold-belt, and four joint ventured projects (June 2011).

Orosur Mining Inc. is a fully integrated gold producer and exploration company focused on identifying and developing gold projects in Latin America. The Company operates the only producing gold mine in Uruguay (San Gregorio), and has assembled an exploration portfolio of high quality assets in Uruguay and Chile. The company is listed on TSX-V and AIM and currently has its head office in Montevideo, Uruguay.

Highlights

• The current mine plan at San Gregorio is to produce 190,000 ounces over the next four years. This production and cost profile is expected to significantly improve with the development of the higher grade Arenal Deeps underground deposit.
• The Pantanillo development project was recently acquired in the Maricunga Belt in Chile . Historical geological work at Pantanillo  by Anglo American (1992-2005) and Kinross Gold (2005-2008)  generated a potential mineral resource estimated  in the range of 82 to 125 million tonnes grading 0.83 to 0.73 g/t gold, using a 0.6 to 0.5 g/t gold cut-off for the lower and higher tonnages  respectively. These estimates equate to 2.18 to 2.95 million ounces of contained gold. This preliminary assessment was made by Kinross Gold in 2007 and was estimated based on a total of 8,398 meters of reverse circulation drilling and diamond drilling. The potential tonnages and grades are conceptual in nature as there has been insufficient drilling to define a mineral resource in accordance with the  National Instrument 43-101 Standards of Disclosure for Mineral Projects and it is uncertain if further exploration will result in the deposit being delineated as a mineral resource. An  exploration and development program targeting the definition of a NI43-101 compliant mineral resource is in with the objective of creating a second production asset for the group within 3 to 4 years.
• The Company is confident that there is further growth potential in its exploration portfolio in Chile and Uruguay including the Anillo project in Northern Chile which is approximately 10 km north east of the El Peñón mine operated by Yamana Gold Inc.

EXPLORATION - CHILE
The Uruguay Mineral Exploration and Fortune Valley merger brings three new projects to the Orosur Mining exploration portfolio in Chile.

The highest priority project, Pantanillo, is at advanced exploration stage.  Pantanillo 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 40 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. (READ MORE)

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. (READ MORE)

The third project, Incahuasi, is targeting an IOCG deposit in the Coastal Cordillera, along the Atacama Fault Zone, within what is known as the Chilean Iron Belt. This project straddles the border of Regions III and IV, in northern Chile . Mineralization is present as an open zone of Au-Cu veins having significant strike length and moderate width and down dip extension. There is potential also for disseminated Au-Cu porphyry mineralization. (READ MORE)

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 Cu-Au 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.
