NEW YORK (MarketWatch) -- Copper prices jumped as much as 5% earlier, and were lately up about 2% on Monday, amid concerns that the earthquake in Chile over the weekend would cause a supply shortage from the world's largest producer of the metal. High-grade copper futures for May delivery rose 2% to $3.35 a pound. Copper pared gains as the disruption will be short lived and Chilean miners have resumed production, analysts at Commerzbank said. Gold futures for April delivery fell $3.30, or 0.3%, to $1,110.20 an ounce, as the dollar gained.
