Gold headed towards its highest close in over a year on Thursday. Futures in the precious metal gained as much as 1.25%, or $16.75 an ounce, to as high as $1,268.45, the highest since last March. This was a part of a broader rally in precious metals that pushed silver to the best levels in about a year, up 1.48% to $17.615 an ounce.
