Taseko Mines Completes Notes Offering and Moves Forward with Florence Copper Commercial Production Facility

VANCOUVER, Feb. 10, 2021 - Taseko Mines Ltd. (TSX: TKO) (NYSE American: TGB) (LSE: TKO) ("Taseko" or the "Company") is pleased to announce that it has completed its offering of US$400 million aggregate principal amount of 7.0% Senior Secured Notes due 2026 ("Notes"). A portion of the proceeds will be used to redeem the outstanding US$250 million 8.75% Senior Secured Notes due 2022 ("Existing Notes"). The remaining proceeds, net of transaction costs and accrued interest, of US$131 million are available for capital expenditures, working capital and general corporate purposes.

Stuart McDonald, President of Taseko, commented, "This bond refinancing and upsize has significantly strengthened Taseko's financial position and lowered our cost of capital. We now have a cash balance of approximately US$200 million and no significant debt maturities until 2026. With the majority of the required funding for our Florence Copper project now in hand, we are moving forward with final design engineering of the commercial production facility as well as procurement of certain critical components."

"Capital requirements for the commercial production facility are estimated at US$230 million," added Mr. McDonald. "We continue to advance discussions with potential joint venture partners, but with our strong cash balance and improved Gibraltar cash flows from copper prices that are currently over US$3.70 per pound, we have numerous options available to obtain the remaining funding."

Russell Hallbauer, CEO of Taseko concluded, "A commitment to capital discipline is a guiding principle for this organization. We have demonstrated this in the past by completing over $800 million of capital programs at Gibraltar, on time and on budget. Florence is no different. We are designing and engineering the commercial facility to achieve the most accretive results for shareholders. Florence is one of the least capital intensive copper production facilities in the world and when fully ramped up will produce 40,000 tonnes of high quality cathode copper annually for the US domestic market. It is a green project, with carbon emissions and water and energy consumption all dramatically lower than a conventional mine, and with C1 operating costs of US$0.90 per pound of copper, it will also be in the lowest quartile of the global cost curve."
