Notes to the Eau Claire Mineral Resource Statement:

  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. Open pit mineral resources are reported at a cut-off grade of 0.5 g/t gold within a conceptual pit shell and underground mineral resources are reported at a cut-off grade of 2.5 g/t gold outside the conceptual pit shell. 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%. 
  3. 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 Clearwater Property. The results are used as a guide to assist in the preparation of a mineral resource statement and to select an appropriate resource reporting cut-off grade.
  4. Pit optimization parameters and cut-off grades are outlined in Table 3 of Eastmain's September 11, 2017 press release.

Notes to the Eastmain Mine Historic Resource:

These resources are historical estimates dated effective May 31, 1995 and should not be relied upon. These estimates may not be National Instrument 43-101 (“NI 43-101”) compliant. While the company considers this historical estimate to be relevant to investors as it may indicate the presence of mineralization, a qualified person for Eastmain has not done sufficient work to classify the historical estimates as current mineral resources as defined by NI43-101 and the company is not treating this historical estimate as current mineral resources.
