  1. Mineral resources which are not mineral reserves do not have demonstrated economic viability. All figures are rounded to reflect the relative accuracy of the estimate. Composites have been capped where appropriate.
  2. The Mineral Resources in this press release were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM"), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions.
  3. Open pit Mineral Resources are reported at a cut-off grade of 0.5 g/t gold and underground Mineral Resources are reported at a cut-off grade of 2.5 g/t gold. Cut-off grades are based on a gold price of US$1,250 per ounce, a foreign exchange rate of US$0.80, and a gold recovery of 95%.
  4. The results from the pit optimization are used solely for the purpose of testing the “reasonable prospects for economic extraction” by an open pit and do not represent an attempt to estimate Mineral Reserves. There are no Mineral Reserves on the Property. The results are used as a guide to assist in the preparation of a mineral resource statement and to select an appropriate Mineral Resource reporting cut-off grade.
  5. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, socio?political, marketing, or other relevant issues.
  6. The Inferred Mineral Resource in this estimate has a lower level of confidence that that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of the Inferred Mineral Resource could be upgraded to an Indicated Mineral Resource with continued exploration.
  7. Mineral Resources which 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. The Inferred Mineral Resource in this estimate has a lower level of confidence that that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of the Inferred Mineral Resource could be upgraded to an Indicated Mineral Resource with continued exploration. The Mineral Resources in this press release were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council. The 2.5 g/t Au cut-off grade utilized in the above table was derived from US$1,250/oz Au, $0.76 US$ exchange rate, C$85/tonne mining cost, C$25/tonne processing cost, C$15/tonne G&A cost and 95% process recovery.
