Metals power higher as sickly dollar spurs copper-to-gold rally

Copper jumped by the most in two months and zinc hit a fresh decade-high as base metals rallied on a potent combination of a softer dollar and continued robust outlook for demand. Gold and palladium also climbed. Copper surged as much as 2.1%, the most since November 13, to $7 259 a metric ton on the London Metal Exchange, and traded at $7 240 at 7:10 a.m. in London , just below where it ended last year. Zinc gained 1.3% to $3 426 a ton to head for the highest close since 2007.
