A salvage crew following a faint metal-detector signal through deep mud off the Florida Keys hauled up a 55-pound copper ingot from the Nuestra Señora de Atocha, a 400-year-old Spanish shipwreck that keeps giving up its secrets.
Captain Drake Nicholas was working from the deck of the salvage vessel DARE, roughly 35 miles west of Key West, when his detector registered a barely-there hit. He dug. The signal grew louder. What he pulled from the seafloor was not the cannon he expected but a crude block of copper that had sat in the mud since 1622.
The ingot is worth an estimated $18,000 to $25,000, according to an August press release from Mel Fisher's Shipwreck Expeditions, the company that has spent decades recovering treasure from the Atocha. But the dollar figure on a single artifact understates the real news: Nicholas says the find is part of a trail that may lead straight to a much larger cache of silver, copper, and coins still buried beneath the ocean floor.
Nicholas told Fox News Digital that the weakest readings on his detector are the ones that get his blood moving.
"Faint hits are always the most exciting because they lead to, you know, stuff very deep in the mud. And I got that very faint hit. I dug down like I always do... and it got louder, and that's, you know, when the excitement really kicks in."
He initially thought the object was a cannon. Copper ingots of this kind were not everyday cargo. Nicholas explained that in the early 17th century, copper was a controlled material, reserved for the Spanish crown's cannon foundries rather than traded freely.
"It wasn't something [that] an everyday guy could have a stockpile of, it was more for the king and queen to make cannons."
The ingots themselves were rough. Workers would dig a hole in the sand and pour molten copper into it. The result was a lumpy bar full of impurities, but valuable enough that the Spanish Empire shipped it across the Atlantic to forge bronze naval guns.
The Atocha went down in a hurricane in 1622 while sailing home to Spain loaded with silver, gold, and emeralds. The wreck sat undiscovered for centuries until treasure hunter Mel Fisher began searching for it in 1969. His company fought a lengthy legal battle for rights to the salvage and prevailed in 1982. Three years later, in 1985, Fisher's team found what they called the "Mother Lode", the main deposit of the ship's cargo.
Even after that landmark discovery, much of the Atocha's treasure remained scattered across the seafloor, buried under layers of sediment that older equipment could not reach. That is what makes the current string of recoveries significant. Earlier this summer, Nicholas and his crew pulled a 22.5-pound silver bar from the same site. Now the copper ingot. And Nicholas says the pieces are forming a pattern.
Nicholas told reporters he has already mapped 19 additional targets that he described as "very interesting, very high-value." New metal-detection technology is allowing the crew to penetrate deeper into the mud than previous generations of salvagers could manage.
"We've never really [gotten] to penetrate that mud with a metal detector to get down and find, you know, the rest of the silver bars, copper ingots and coins."
He did not specify what those 19 targets might contain, but he was blunt about his confidence.
"The size of what we've been finding lately is... leading us to what I believe is the rest of the treasure."
Nicholas added that reaching the targets will require extensive excavation through thick sediment, work that takes time and patience. But the payoff, he believes, could dwarf anything recovered in recent years.
"And it's a lot of digging through that mud and getting down to that level. But once I'm there, I'm very, very confident and excited, we're just very excited to see where this is leading."
Mel Fisher spent 16 years hunting the Atocha before his team struck the Mother Lode. His successors are still at it four decades later, chasing faint signals through the mud 35 miles offshore. The copper ingot is one artifact. The 19 targets on the map ahead could be the next chapter, or the last one.
In an age when so many institutions quit at the first obstacle, there is something refreshing about a crew that keeps digging because the signal, however faint, says there is more down there.
