The base metals were mixed again on Thursday. Copper sank during the pre-dawn hours and fought its way back during the New York session though it fell short of positive territory at $3.6068/lb., down more than a penny and a third.

Outside of nickel, the base metals were all on fire on Friday. Copper rose straight from the pre-dawn hours until the late morning, only then coming off its intraday highs to finish at $3.866/lb., up nearly 8 cents.
