CHICAGO, June 13 (Xinhua) -- Gold futures on the COMEX division of the New York Mercantile Exchange edged slightly higher on Wednesday, as the U.S. dollar weakened before Federal Reserve lifted a key interest rate.
The most active gold contract for August delivery went up 1.9 dollars, or 0.15 percent, to close at 1,301.3 dollars per ounce.
The U.S. dollar index, which measures the buck against six rivals, went down 0.19 percent to 93.59 as of 1830 GMT.
Gold and the dollar typically move in opposite directions, which means if the dollar goes down, gold futures will rise.
