There were already attempts to salvage the wreck of the ship Slot ter Hoge in the 18th century by John Lethbridge who was hired by the Dutch in 1725, only a year after the wreck. But excavation of the site was not done on a proper level until Robert Sténuit excavated the wreck in the 1970s.

An article was written by Sténuit regarding this wreck. "The treasure of Porto Santo" was published by National Geographic in August of 1975.
