  1. The resource and reserve estimation was completed under the supervision of Richard Weymark, P. Eng., MBA, Vice President, Engineering for Taseko and a Qualified Person as defined by NI 43-101.
  2. Gibraltar Mineral Reserves and Mineral Resources reflect depletion due to mining in 2022 as documented in the Company’s Annual Information Form for the Year Ended December 31, 2022 which is available on SEDAR.
  3. Gibraltar Mineral Reserves and Mineral Resources follow CIM Definition Standards for Mineral Resources and Mineral Reserves (2014).
  4. Sulphide Mineral Reserves are exclusive of Oxide Mineral Reserves.  Both Sulphide Mineral Reserves and Oxide Mineral Reserves are contained within Mineral Resources.
  5. Oxide Mineral Reserve grades are reported in-terms of acid soluable copper.
  6. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
  7. Mineral Reserves are assumed to be extracted using open pit mining methods and are based on US$3.05/lb Cu price, $12.00/lb Mo price, exchange rate of US$0.80=C$1.00, metallurgical recoveries of 85% TCu and 40% Mo for sulphide ore and 50% ASCu for oxide ore.
  8. The Mineral Resource has been confined by a “reasonable prospects of eventual economic extraction” pit using the following assumptions: Cu price of US$3.50/lb, Mo price of US$14.00/lb, exchange rate of US$0.80=C$1.00, metallurgical recoveries of 85% for TCu and 40% for Mo.
  9. A tonnage factor of 12ft3/ton has been applied for rock and 15ft3/ton for overburden and fill.
  10. Additional information regarding data verification, exploration information, known legal, political, environmental or other risks can be found in the report entitled “Technical Report on the Mineral Reserve Update at the Gibraltar Mine, British Columbia, Canada” issued March 30, 2022  with an effective date of Match 15, 2022 which is available on SEDAR.  The Gibraltar Technical Report was prepared under the supervision of Richard Weymark, P. Eng., MBA. Vice President, Engineering of Taseko and a Qualified Person as defined by NI 43-101.
