Gold rose more than 1 percent on Tuesday, partially recouping the previous session's tumble, as buying related to options' expiration lifted bullion prices toward the key $1,700-an-ounce option strike price. Spot gold gained 1.2 percent to $1,697.99 an ounce by 3:04 pm EST (2004 GMT). The December COMEX option was by far the most popular month and $1,700 strike had one of the highest open interest among all the strikes, with around 6,500 lots, Reuters data showed.
Silver rose 3.5 percent to $32.76 an ounce, recovering from a one-month low of $30.63 hit in the previous session. Platinum rose 1.2 percent to $1,565.25 an ounce, and palladium gained 2.8 percent to $600.97 an ounce.
