Secret Tunnel Found Below Garden Shaft — Leads Towards Aladdin’s Cave,Gold in the Water, Metal Below the Shaft: Oak Island Mystery Deepens
New Tunnels Unearthed in Garden Shaft Operation
During the final episodes of The Curse of Oak Island Season 12, Dumas Contracting made significant progress in the Garden Shaft excavation. After reinforcing the shaft and draining excess water, the team discovered multiple wood structures and cavities—indicating old tunnel systems possibly linked to past searcher activity or original depositors.
Most notably, a promising tunnel was located 12 feet below the shaft’s main level, stretching toward the east. As the excavation team descended, they encountered layered wood structures, black organic sediment, and evidence of deliberate construction. Marty Lagina and Craig Tester were especially intrigued when they found fibrous black material resembling coconut fiber—a material historically associated with Templar booby traps and the flood tunnel system

Magnetometer Scans Reveal Metallic Signature Under the Shaft
Emma Culligan led a magnetometer scan directly beneath the Garden Shaft. The results showed a distinct and unusually strong magnetic anomaly approximately 15 feet below the shaft’s base. The size and intensity suggested the presence of a large metallic object—possibly silver or gold. This discovery reinvigorated hopes that treasure or an ancient vault may be located at the bottom of the shaft or within nearby tunnels.
Scientific Analysis Links Gold to the Water System
Water samples collected from boreholes and shaft pumps underwent detailed chemical analysis. Emma Culligan and the scientific team detected trace amounts of gold in multiple samples, including those from the tunnel area east of the Garden Shaft. This indicates gold is present in the underground system, and that it may have been leaking from a nearby cache for years.
Emma Culligan and Katya Drayton Examine Tunnel Artifacts
Two young experts, Emma Culligan and Katya Drayton, conducted metallurgical and archaeological examinations on artifacts recovered from the shaft tunnels. Among them were rusted iron brackets, wooden braces with chisel markings, and a strange circular iron object with Roman-style notches. The artifact showed signs of pre-industrial manufacturing, suggesting an age older than previous searcher digs.

Links to the Knights Templar and a Hidden Vault
These findings—especially the coconut fiber, gold traces, and unusual tunnel architecture—have fueled theories about a secret Templar vault. Historical maps, including the old Nolan Map and archival French records, suggest that a Templar or early European group may have engineered the shaft system to guard something valuable. The tunnel discovered to the east, reinforced with ancient timber and pointing toward Aladdin’s Cave and E5N14, may connect directly to this long-rumored vault.
Conclusion: A Turning Point in the Oak Island Mystery
Season 12 ended with several game-changing discoveries:
- A new tunnel system beneath the Garden Shaft
- Scientific proof of gold in the underground water
- Magnetic evidence of a large metal object below the shaft
- Ancient construction techniques found in tunnel artifacts
These findings point to something significant hidden deep beneath Oak Island. While the mystery is not yet fully solved, the Lagina brothers and their team now have more scientific proof and physical evidence than ever before—setting the stage for a breakthrough in Season 13.
