Note: Proven and Probable reserves are derived from Measured and Indicated resources, respectively, that are contained within the final ultimate design and are above the stated copper cut-off grade as of December 31, 2019. Mineral Reserves have been estimated in accordance with NI 43-101 and 2014 CIM Definition Standards. Mineral reserves were estimated using long term metal prices of US$2.40/lb Cu, US$1,000/oz Au and US$13.50/oz Ag at a foreign exchange rate of US$0.80 per C$1.00 and a 0.17% cut off grade. Totals may not sum due to rounding.

Note: Mineral Resource estimate with an effective date of December 31, 2019. Mineral Resources have been estimated in accordance with NI 43-101 and 2014 CIM Definition Standards. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. Mineral resources were estimated using long term metal prices of US$3.25/lb Cu, US$1,300/oz Au and US$17.00/oz Ag at a foreign exchange rate of US$0.80 per C$1.00 and a 0.15% cut off grade. Mineral Resources are inclusive of Mineral Reserves. Totals may not sum due to rounding.
*Copper Equivalent is based on 90% copper recovery, US$3.10/lb copper price, 56% gold recovery, US$1350/oz gold, 59% silver recovery, and US$18.00/oz silver price.
The resource and reserve estimation was completed by Taseko staff and contributing consultants under the supervision of Richard Weymark, P. Eng., MBA. Chief Engineer, Taseko and a Qualified Person under National Instrument 43-101.
