"We are satisfied with full year results as they came in within our expectations particularly given the delay in the startup of a strategic customer," said Nick Carter, President and Chief Executive Officer of Arabian American. "The change in volume from the prior year's comparable quarter was the result of several factors including a planned maintenance shutdown and the resolution of a competitor's production outages. Additionally, our customer's delay in production at the Canadian tar sands project carried through in fourth quarter 2012. Going forward, it is our understanding that the tar sands' orders are coming back online in the second quarter and will continue for the remainder of 2013. Combined with the AMAK mine, which began shipping copper and zinc concentrate late last year, we feel that we have good momentum moving into 2013."Earnings Call Arabian American will host a conference call and live webcast at 4:30 p.m. Eastern Time, Thursday, March 7, 2013.
