CHICAGO, May 15 (Xinhua) -- Gold futures on the COMEX Division of the New York Mercantile Exchange inched higher on Friday as the core Consumer Price Index (CPI) for last month rose, raising investors' inflation worries. Silver and platinum both went down.

    Gold price for June delivery gained 2.90 U.S. dollars, or 0.3 percent, to settle at 931.30 dollars an ounce.

    The U.S. Labor Department reported on Friday the CPI for April fell 0.7 percent after dipping 0.1 percent in March, but the core CPI which excluding energy and food was up 1.9 percent over the past 12 months, following Thursday's producer price index (PPI) climbing 0.3 percent in April. The data were considered as a sign of potential inflation in the future, sparking gold's demand as a hedge against inflation.

    The report also showed U.S. industry remains weak. Industrial production has fallen in 15 of the 17 months since the recession began in December 2007, and is down 16 percent since then.

    July silver finished at 14.01 dollars per ounce, down 3 cents. July platinum fell 8.50 dollars to 1,109 dollars an ounce.
