By Claudia Assis, MarketWatch SAN FRANCISCO (MarketWatch) — Gold futures rose modestly on Friday, looking to snap a two-day losing streak as investors bought the metal ahead of the weekend and the potential for worrying headlines. Gold for December delivery GC1Z +0.85% added $9.50, or 0.5%, to $1,790.80 an ounce on the New York Mercantile Exchange. Other metals also trade higher, with December silver SI1Z +1.93% trading up 68 cents, or 1.8%, to $40.18 an ounce. Earlier, U.S. Treasury Secretary Timothy Geithner urged euro-zone finance ministers and the European Central Bank to show unity to solve the region’s debt crisis and enhance the euro zone’s rescue fund. The officials are meeting in Wroclaw, Poland, and Geithner is the first U.S. Treasury Secretary to attend an informal meeting of the euro-zone finance ministers, underscoring the U.S.’s anxiety over the problems in the area. Gold dropped below $1,800 on Thursday after the European Central Bank announced a concerted move with other central banks to provide more liquidity for European banks. The steep 2.5% loss, to $1,781.40 an ounce, took the gold contract to the lowest since Aug. 25. Claudia Assis is a San Francisco-based reporter for MarketWatch.
