Notes to the MRE:

  1. Mineral resources are not mineral reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the mineral resources will be converted into mineral reserves.
  2. The mineral resource for the Whistler, Island Mountain, and the upper portions of the Raintree West Deposits have been confined by an open pit with “reasonable prospects of eventual economic extraction” using the following assumptions:
    • metal prices of US$2,750/oz Au, US$4.35/lb Cu and US$30/oz Ag;
    • payable metal of 94.8% payable for Au, 96.5% payable for Cu, and 88.2% payable for Ag;
    • refining costs for Au of US$7.50/oz, for Ag of US$1.00/oz and for Cu of US$0.065/lb;
    • off-site costs of US$165.65/t;
    • royalty of 3% Net Smelter Return (NSR);
    • pit slopes are 50 degrees;
    • mining cost of US$2.75/t for waste and mineralized material; and
    • processing costs of US$11.25/t, general and administrative costs of US$2.15/t.
  3. The open pits at Whistler and Island Mountain use the 150% NSR case, with the upper portion of Raintree West using the 100% NSR case. The lower portion of the Raintree West deposit has been constrained by a mineable shape within a “reasonable prospects of eventual economic extraction” shape using a $40.00/t cutoff value.
  4. Metallurgical recoveries are: 87.8% for Au, 75.4% for Cu, and 49.1% Ag.
  5. The NSR equation is: NSR ($/t)=(100%-3%)*((Au(g/t)*87.8%*$78.57/g) + (Cu%*75.4%*$3.88/lb*2204.62 + Ag(g/t)*49.1%* $0.77)).
  6. The gold equivalent equation is: AuEq=Au + Cu*0.9361 + 0.0055Ag.
  7. The specific gravity for each deposit and domain ranges from 2.76 to 2.91 for Island Mountain, 2.60 to 2.72 for Whistler with an average value of 2.80 for Raintree West.
  8. Numbers may not add due to rounding.
