The Financial Post reports in its Friday edition that Teck Resources, which is being acquired by Anglo American PLC, posted a jump in earnings aided by higher copper prices, while reaffirming output guidance including at the problematic Quebrada Blanca mine in Chile. A Bloomberg dispatch to the Post says adjusted earnings before interest, taxes, depreciation and amortization rose to $1.51-billion for the final three months of last year, up from $835-million year ago. That topped the average analyst estimate tracked by Bloomberg. Revenue rose to $3.06-billion. Copper surged by more than 40 per cent last year and hit a record last month, aided by a wave of speculative buying, U.S. tariff risks and enthusiasm about demand for the metal that is vital to the energy transition.
