Pirates of the Gulf of Mexico?

The Interior Department's Minerals Management Service, working with the University of Texas, has launched an effort to explore a shipwreck lying in 4,000 feet of water 40 miles off the coast of Louisiana. That makes it the "deepest shipwreck in the world ever to be scientifically excavated for a non-commercial purpose," MMS says. Very little is known about the ship, which sank between 1780 and 1820, but archaeologists speculate it might be a merchant ship or privateer. Meaning that it just might contain some very interesting "minerals," no?
