Precious metals prices mixed on session

Precious metals prices were mixed Monday as gold and silver saw gains but platinum and palladium declined.

June gold added $1.60 to $928.60 per troy ounce in New York while May silver was up 10 cents to $17.79 per troy ounce.

Both were higher after the US dollar again declined in relation to the euro.

On the other hand, July platinum dropped $46.60 to $1,981.50 per troy ounce while palladium was down $12.55 to $462.80 per troy ounce.

Among base metals, copper prices were lower as investors again began to worry that a slow economy would hurt demand for metals used in industry.

May copper was down 5 cents to $3.90 per pound in New York, while three-month copper dropped $105 to $8,545 per tonne, or $3.88 per pound, in London as London Metal Exchange stockpiles gained on the session.
