Taseko Announces Improved Economics at Its Florence Copper Project IN Arizona

Corporate Updates

TASEKO ANNOUNCES IMPROVED ECONOMICS AT ITS FLORENCE COPPER

PROJECT IN ARIZONA

January 16 2017, Vancouver, BC – Taseko Mines Limited (TSX: TKO; NYSE MKT: TGB) (“Taseko” or the 

"Company")  is  pleased  to  announce  that  recently  completed  technical  work  on  the  Florence  Copper 

Project has resulted in a significant improvement in project economics. 

Russell Hallbauer, President and CEO of Taseko, stated, “In addition to the permitting milestones achieved 

over the past months, we are very pleased with the outcome of the latest engineering work which has 

increased the net present value (NPV) of the project to US$920 million. Contributing to the higher NPV is 

an 11% increase in average annual copper production, combined with slightly lower operating costs and 

pre‐production capital. With annual copper production of 81 million pounds and pre‐production capital 

of US$200 million, Florence Copper is one of the least capital intensive copper projects in the world.” 

Project Highlights: 

 Pre‐tax net present value of US$920 million at a 7.5% discount rate 

 Pre‐tax internal rate of return of 44% with a 2.3 year payback 

 Operating costs of US$1.10 per pound LME grade cathode copper 

 Total life of mine production in excess of 1.7 billion pounds of copper  

 Average annual production of 81 million pounds of copper for the life of mine 

 21 year mine life 

 Total pre‐production capital cost of US$200 million 

 Long‐term copper price of US$3.00 per pound 

“Two important parameters for any copper leaching process are copper recovery and acid consumption,” 

continued Mr. Hallbauer. “The copper recovery estimate of 70% from the 2013 technical report as well as 

the acid consumption estimate have both been confirmed with the more detailed testing.” 

“As we continue to perform additional technical work on our Florence Copper Project, the project is not 

only being de‐risked, but operational and environmental attributes which were already very strong, are 

improving. It is our goal to commence construction on the production test facility in 2017 and advance 

this project towards being a second cash‐flowing asset for Taseko,” concluded Mr. Hallbauer. 

Since Taseko’s acquisition of the Florence Copper Project, two important project development initiatives 

have  been  finalized  which  verify  and  expand  upon  the  extensive  technical  work  undertaken  by  the 

previous  owners.  A  two‐year  long  in‐series  pressurized  cell  leach  test  was  completed.  This  test  was 

designed to more closely replicate in‐situ leaching conditions and provide information on a larger scale 

than  previous  leach  tests.  The  results  have  verified  and  greatly  increased  the  confidence  in  the 

metallurgical input data used to simulate the performance of the project once it reaches production. In 

parallel  with  the  leach  test,  an  optimization  of  the  project  well  field  development  sequence  was 

performed. The entire project was then re‐simulated and re‐costed using updated inputs including the 

verified leach performance data. 

The well field sequence developed for the optimized project plan increases copper production in the first 

five  years  of  operations  by  50%,  compared  with  the  previous  project  plan,  and  requires  less  pre‐

production capital than previously estimated. 

The  changes  to  the  development  plan  have  also  resulted  in  an  increase  in  the  Florence  Copper  ore 

reserves.  There was no change to the mineral resources.
