"It's going to be a very difficult hurdle for gold to reach the $1,300 level and that might not happen until we see more seasonal demand coming into play or if the dollar strength starts to ease, which we don't think will happen till later in the year."

The gold-silver ratio, which measures the number of silver ounces needed to buy an ounce of gold, climbed to its highest level since 1993 at around 89.
