Gold prices gained half a percent on Friday, following a rebound in other commodities, but uncertainty about the eurozone's resolution of its debt crisis is likely to cap gains. Spot gold gained half a percent to stand at $1,626.29 an ounce by 0628 GMT, but was headed for a weekly drop of 3.2 percent, its biggest such decline in nearly a month.
US gold rose as much as 1.1 percent to $1,630.9, before easing to $1,627.90, on course for a weekly fall of 3.3 percent.
