Resources are based on a 0.1% Cu cut-off grade. For Cu and Au eq., the commodity prices used are as follows: UU$ 3.25/lb Cu, US$1650/oz Au, US$10.00/lb Mo and US$1,256/kg Re. Assumed 100% recovery. Amounts may not total due to rounding.
Note that the preliminary economic assessment is preliminary in nature. It includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary economic assessment will be realized.
