Deltic's sawmill operations consist of two state of the art Southern Pine mills, one located at Ola in central Arkansas and the other at Waldo in south Arkansas. Combined annual capacity at year-end 2010 was 390 million board feet. The mills are strategically located near significant portions of the Company's timberland and process company-owned timber as well as

timber purchased from public and private landowners. The Ola mill is equipped for maximum utilization of smaller diameter logs, while the Waldo mill can process both smaller and larger diameter logs. The mills produce a variety of products, including dimension lumber, boards, timbers, decking, and secondary products such as finger-jointed studs.
