Note: The mineral resource and reserve estimations were completed by Taseko staff under the supervision of Scott Jones, P.Eng., Vice-President, Engineering 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 estimates for the reserves used long term metal prices of US$1.65/lb for copper and US$650/oz for gold and a foreign exchange of C$0.82 per US dollar..
