PLATINUM: Spot platinum prices last traded at $1,577 an ounce, which is 0.6%, or $10, above Tuesday's settlement.
PALLADIUM; Its sister metal also made gains. Spot palladium prices were up 1.6%, or $7, to end the day at $447 an ounce. Given that both metals are used in auto-manufacturing, they've extended gains made in the previous day after an uplifting day of positive February auto-sales news.
SILVER: Silver, also an industrial metal, was last trading at $17.20 an ounce, which is 1.5%, or 26 cents, above the previous day's close.
