The reserve estimation (effective date Sept 15 2014) was reviewed by Scott Jones, P.Eng., Vice-President Engineering for Taseko and a Qualified Person under National Instrument 43-101. Mr Jones has verified the methods used to determine grade and tonnage in the geological model, reviewed the long range mine plan, and directed the updated economic evaluation. The study was done using long term metal prices of US$45.00/kg for niobium and an exchange rate of US$0.90/C$1.00. The NI 43-101 compliant reserve estimate takes into consideration all geologic, mining, milling, and economic factors, and is stated according to Canadian standards. (Under US standards no reserve declaration is possible until a full feasibility study is completed and financing and permits are acquired.) . Mineral reserves are contained within the measured and indicated mineral resources.
