  2. 2. FORWARD LOOKING STATEMENT Certain statements in this document constitute “forward looking statements” which may not be based on historical fact. Such forward looking statements involve known and unknown risk, uncertainties and other factors which may cause the actual results, performance or achievements of the Company, or industry results to be materially different from any future results, performance, or achievements expressed or implied by such forward looking statements. Such factors include, among others, the following: actual results of exploration and development activities; the costs and timing of the development of new deposits; future prices of precious and base metals; accidents; risks inherent in mineral exploration; risks associated with development, construction and mining operations; restrictions on foreign ownership; the Company’s history of operating losses and uncertainty of future profitability; uncertainty of access to additional capital; and environmental liability claims and insurance. This presentation is not an offer to purchase securities and does not constitute an offering document under Securities legislation.

CIM definition standards were followed for the resource estimate. 2. The 2012 resource models used Inverse Distance grade estimation within a three-dimensional block model with mineralized zones defined by wireframed solids. 3. A base cutoff grade of 0.6 g/t AuEq was used for reporting resources with capping of silver grades at 591 g/t. 4. A density of 2.65 g/cm3 was applied. 5. Numbers may not add exactly due to rounding. 6. Gold Equivalent (AuEq) calculated using $1264 /oz Au for gold and $19.78/oz Ag for silver and metallurgical recoveries and net smelter returns are assumed to be 100%. 7. Mineral Resources that are not mineral reserves do not have economic viability 8. The quantity and grade of reported inferred resources in this estimation are uncertain in nature and there has been insufficient exploration to define these inferred resources as an indicated or measured mineral resource and it is uncertain if further exploration will result in upgrading them to an indicated or measured mineral resource category.

Assumes metallurgical recoveries and net smelter returns are to be 100% 2. Mineral resources that are not mineral reserves do not have economic viability. 3. A base cutoff grade of 0.6 g/t AuEq was used. Riscos estimate used a capping of silver grades at 591 g/t. a density of 2.65 g/cm3 was applied. Numbers may not add exactly due to rounding. 1. Base case is reported at a 0.15% copper equivalent cut-off grade which incorporates consideration of mining and processing cost, recoveries, commodity prices and selling cost. 2. Estimate assumes a long term copper price of US$2.90/lb, a gold price of US$1,200/oz and a silver price of US$24/oz. 3. Rounding as required by NI 43-101 reporting guidelines may result in apparent summation differences. 4. Tonnage and grade measurements are in metric units. Contained gold and silver ounces are reported as troy ounces, contained copper pounds as imperial pounds. 5. Mineral resources that are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues. 6. The quantity and grade of reported inferred mineral resources in this estimation are uncertain in nature and there has been insufficient exploration to define these inferred mineral resources as indicated or measured mineral resources and it is uncertain if further exploration will result in upgrading them to indicated or measured mineral resources.
