 Taseko Mines Ltd TSX:TKO said it expected improved production in the first quarter and more consistent output through 2023 after a power outage hit its Canadian copper mine in December. The 74 owner and operator of the Gibraltar mine - the second largest open pit copper mine in Canada - said although power was out for only 24 hours, the severe cold temperatures froze a number of essential systems in the mills, delaying the restart of operations for several days.
