(Kitco News) - Gold prices are moderately lower in early morning U.S. trading Thursday. The stronger U.S. dollar index that scored another fresh 7.5-month high overnight continues to limit buying interest not only in gold and silver, but in many other commodity markets, too. The overall near-term technical postures for gold and silver continue to favor the bearish camps, and that is also limiting speculator demand for both. April Comex gold last traded down $11.10 at $1,577.00 an ounce. Spot gold was last quoted down $11.20 at $1,577.00. May Comex silver last traded down $0.403 at $28.55 an ounce.
