The ship was first located in 1988 by a young marine expert called Thomas Thompson, who secured investors and put together an operation that went on to recover two tonnes of gold, worth about US$76 million ($87 million) in today's money. He is on the run amid a mystery over the whereabouts of 500 gold coins, worth about US$26,500 each, and complaints by investors in his Columbus America Discovery Group, which carried out the initial recovery operation, that they never received their share of the hoard. As the years went by, further claims flooded in from those whose antecedents lost the treasure in the first place, including an order of Catholic monks, a Texas oil millionaire and a university, as well as the dozen or more insurers that had paid out over the sinking.
After their complicated claims were untangled this year, Judge Patrick Sheeran appointed a receiver, who in turn hired the company Odyssey Marine Exploration to bring up the remaining treasure. During its robot dive last month, Odyssey recovered five gold bars weighing 30kg, worth about US$1.2 million. More gold, worth an estimated US$85 million, remains in the wreck.
