DMT Concentrate Storage BuildingsThe Delong Mountain Terminal Port is connected to the Red Mine by a 52-mile long gravel road. The road and the port facility together make up the DeLong Mountain Transportation System (DMTS). The DMTS is owned by Alaska industrial Development and Export Authority (AIDEA), a public agency that has contracted with Cominco for its use, operation, and maintenance. The port facility is on property owned by NANA, which is leased by AIDEA, and is operated by Teck Cominco.

Ore containing lead and zinc is milled at the Red Dog mine to DMTS Haul Road and revegitated concentrate spill siteproduce lead and zinc concentrates in a powder form. Concentrate is hauled year-round from the mine via the DMTS haul road to two concentrate storage buildings (CSBs) at the Port Site, where they are stored for later loading onto barges during the summer months. Concentrate is moved from the CSBs to barges by conveyors. A surge bin at the dock area provides storage capacity and a steady flow rate for the shiploader boom conveyor. The barges transport the concentrate to deepwater ships anchored offshore.

Barge Loading ConveyorConcentrate storage in the CSBs began in November 1989, and barge loading and shipping of concentrate began in July 1990. The second CSB was added as part of a production rate increase between 1996 and 1998.
