Ag-Eq = Ag + (Cu% x 22.046 x Cu price x 31.103/Ag price + Zn% x 22.046 x Zn price x 31.103/Ag price). A cut-off of 85 g/t Ag-Eq was used for the Base Case. Metal prices used for the formula: silver = $US19/oz, copper = $US3.00/lb, zinc = $US0.90/lb. As there is no metallurgical testing results available, for the purposes of silver-equivalent, recoveries are assumed to be 100%.
As required by NI43-101, it is hereby stated that Mineral Resources are not Mineral Reserves because there is insufficient study conducted to demonstrate economic viability. It cannot be assumed that all or part of an Inferred Resource will be upgraded to an Indicated or Measured Resource with further exploration.
