1. 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 gold and $19.78/oz Ag 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.
