1.6 Mineral Reserves
Mineral Reserves are constrained within specific pit designs that are based on Measured and
Indicated Mineral Resources only and take into consideration all appropriate modifying factors
including metallurgical parameters, geotechnical parameters, infrastructure requirements and
permitting requirements. The modifying factors used to determine the Mineral Reserves for the
project are detailed in Section 15 of the technical report.
This Mineral Reserve estimate has been determined and reported in accordance with Canadian
National Instrument 43-101, ‘Standards of Disclosure for Mineral Projects’ of June 2011 and the
Definition Standards adopted by CIM Council in November 2010.
The Mineral Reserves were based on the various cut-offs derived from various gold
recovery/process costs for the different material types and haulage distance from each specific
deposit to the process plant.
Table 1.3 provides a summary of the Mineral Reserves, determined as of 31st December 2012.

The following notes should be read in conjunction with Table 1.3 above:
1. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
2. Tonnage of waste to be mined is 60.2Mt. This waste amount includes 506kt of Inferred Mineral resources at an
average grade of 2.2g/t. The strip ratio over life of mine is 4.6 to 1.
3. The Lerchs-Grossmann pit shells on which the open pit designs are based, were defined using an overall pit slope
of 37 to 45 degrees (depending on geotechnical settings of each of five deposits, details provided in Section 15 of
the technical report), a commodity price of US$1,350/oz Au, process recovery based on mineralization type
(details provided in Section 15) and selling cost of US$67.5/oz of Au sold.
4. Tonnages are rounded to the nearest 1,000 tonnes; gold grades are rounded to one decimal place; ounces are
rounded to the nearest 100 ounces. 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.
