(Kitco News) - Gold futures prices are modestly lower in early U.S. trading Friday, as a “risk-off” trader and investor mentality in the market place to end the week is not benefitting the safe-haven yellow metal. A stronger U.S. dollar index and lower crude oil prices are bearish outside market forces working against the precious metals Friday morning. April Comex gold last traded down $6.10 at $1,572.00 an ounce. Spot gold was last quoted down $6.40 at $1,573.50. May Comex silver last traded down $0.272 at $28.16 an ounce.
