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.

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.
