Summary of key activities in the fourth quarter: 1) Process ponds and surface water runoff pond construction completed. 2) Solvent extraction settler and launder modules placed and welding of the modules was commenced. 3) 17 production wells were fully constructed in the quarter, for a total of 51 wells out of 90 to be drilled during the construction phase. 4) Development of the main pipe corridor (from wellfield to process plant) is mostly completed and installation of high density polyethylene piping in the corridor is ongoing. 5) Field erected process and service tank construction commenced. 6) Mechanical and piping installations are underway throughout the SX/EW plant. 7) Erection of structural steel for the solvent extraction pipe rack is nearing completion and piping installation is underway. Electrical work commenced. 8) Water treatment building was erected, and preparations made to start the electrowinning building erection.

Stuart McDonald, President & CEO, said, “We are very pleased with the progress that has been made in the first 12 months of construction. The project remains on schedule, and construction costs remain in line with our previous guidance. We are now less than a year from anticipated first copper production and, in addition to construction activities, our site management team is focussed on operational readiness, key vendor agreements and recruiting.

“With continued growth in US copper demand and an increasing focus on security of supply chains for critical materials, it is great timing to be bringing on a new source of domestic copper supply. Florence Copper is the only greenfield copper mine currently under construction in the USA and will soon become the third largest copper cathode producer in the country1.”

“We have recently been informed that our application for the Department of Energy’s 48C(e) tax credit has been declined. However, Taseko remains in a strong financial position with C$330 million of available liquidity at year-end, including the undrawn US$110 million revolving credit facility,”
