Gold edged up on Friday, but prices were on track for their biggest weekly drop since the start of the month with an uncertainty about crucial US talks to avert a fiscal crisis continuing to hit sentiment. Spot gold inched up 0.3 percent to $1,729.55 an ounce by 0739 GMT, headed for a 1.3 percent weekly drop but a 0.5 percent monthly gain. US gold was up 0.1 percent at $1,729.70.
