VANCOUVER, Oct. 21, 2019 /CNW/ - Taseko Mines Limited (TSX: TKO; NYSE American: TGB) ("Taseko" or the "Company") is pleased to provide an operational update on its Florence Copper Project.

In the last nine months, Florence personnel have commissioned the 24-hole test wellfield consisting of injection, recovery and monitoring wells, while ramping up the SX/EW Plant to design capacity. This multi-step process included the initial leaching period where hydraulic control of solutions 800-1200 feet underground, in the orebody, remained compliant with all environmental guidelines. At the same time, the process of recovering copper rich solutions from the orebody commenced, in accordance with Taseko's detailed process design.

Russell Hallbauer, CEO and Director of Taseko, commented, "With steady-state operation now achieved, our focus has turned to testing different wellfield operating strategies, including adjusting pumping rates, solution strength, flow direction, and the use of packers in recovery and injection wells to isolate different zones of the orebody.  Sweep efficiencies in the wellfield continue to outperform our expectations. Our technical team is using physical and operating control mechanisms to adjust solution chemistry and flow rates and is successfully increasing copper concentration in solution. The main recovery well is now producing copper in solution at an annualized rate of approximately 600,000 pounds per year, and the expectation is for steady improvement as the well matures. We are gaining valuable operating experience that will be used to reduce the ramp up period for commercial wellfield operations."

"With the ongoing success of both the wellfield and SX/EW Plant, the Company has recently awarded the basic engineering contract for the commercial facility to Stantec, and that work has now commenced. Additionally, our senior personnel are actively engaged with the Environmental Protection Agency and the Arizona Department of Environmental Quality to advance commercial operating permits which are expected to be granted in the summer of 2020," concluded Stuart McDonald, President of Taseko.
