Mineral Resource Estimate

Notes to Table 1:

  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. Inferred mineral resources are subject to uncertainty as to their existence and as to their economic and legal feasibility. The level of geological uncertainty associated with an inferred mineral resource is too high to apply relevant technical and economic factors likely to influence the prospects of economic extraction in a manner useful for evaluation of economic viability.
  3. The Mineral Resource Estimate 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 economic extraction” using the following assumptions:
    • Metal prices of US$1,850/oz Au, US$4.00/lb Cu and US$23/oz Ag;
    • Payable metal of 95% payable for Au and Ag, and 96.5% payable for Cu
    • Refining costs for Au of US$8.00/oz, for Ag of US$0.60/oz and for Cu of US$0.05/lb.
    • Offsite costs for Au of US$77.50/wmt, for Ag of US$3.50/wmt and for Cu of US$55.00/wmt.
    • Royalty of 3% NSR;
    • Pit slopes are 50 degrees;
    • Mining cost of US$2.25/t for waste and mineralized material; and
    • Processing, general and administrative costs of US$7.90/t.
  4. The lower portion of the Raintree West deposit has been constrained by a mineable shape with “reasonable prospects of eventual economic extraction” using a US$25.00/t cut-off.
  5. Metallurgical recoveries are: 70% for Au, 83% for Cu, and 65% Ag for Ag grades below 10g/t. The Ag recovery is 0% for values above 10g/t for all deposits.
  6. The NSR equations are: below 10g/t Ag: NSR (US$/t)=(100%-3%)*((Au*70%*US$54.646/t) + (Cu*83%*US$3.702*2204.62 + Ag*65%*US$0.664)), and above 10g/t Ag: NSR (US$/t)=(100%-3%)*((Au*70%*US$56.646g/t) + (Cu*83%*US$3.702*2204.62))   
  7. The Au Equivalent equations are: below 10g/t Ag: AuEq=Au + Cu*1.771 +0.0113Ag, and above 10g/t Ag: AuEq=Au + Cu*1.771
  8. 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.
  9. The SEC definitions for Mineral Resources in S-K 1300 were used for Mineral Resource classification which are consistent with Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Definition Standards for Mineral Resources and Mineral Reserves (CIM (2014) definitions).
  10. Numbers may not add due to rounding.

Additional details of the mineral resource estimate are set forth in the S-K 1300 Report titled “S-K 1300 Technical Report Summary Initial Assessment for the Whistler Project”, Effective Date 12 September 2024 and Date of Issue 7 October 2024, a copy of which is available under the Company's profile at www.sec.gov.
