  1. The mineral resources and reserves have been estimated and reported in accordance with Canadian National Instrument 43-101, 'Standards of Disclosure for Mineral Projects' and the Definition Standards adopted by CIM Council in May 2014.
  2. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
  3. All Mineral Resources are reported inclusive of Mineral Reserves.
  4. Tonnages are rounded to the nearest 100,000 tonnes; gold grades are rounded to two decimal place; ounces are rounded to the nearest 1,000oz. Rounding may result in apparent summation differences between tonnes, grade and contained metal.
  5. Tonnes and grade measurements are in metric units; contained gold is in troy ounces.
  6. The reporting of Mineral Reserves and Resources are based on a gold price as detailed below:

    1 Cut off grades for all resources open pits are 0.5g/tAu, except at Kalana where the cutoff grade is at 0.9g/tAu and at Karma where the cut-off grade is defined by material type: Oxide=0.2, Transition=0.22 and Sulfide=0.5

    2 North Kao resources has a gold price of $1,500/oz
