Season 9 in brief
Dr. Ian Spooner's water analysis detects gold in Money Pit boreholes, and the team organizes its entire season around tracing the precious metals to their source. Twenty new boreholes are drilled, and five massive ten-foot-wide caissons are sunk in succession, the largest excavation effort in Oak Island's history. One of them, TF1, produces wood from tunnel depth along with the chemical signatures the team has been chasing. But the season's most unexpected discovery comes underground: the Garden Shaft, initially dismissed as a 19th-century searcher tunnel, returns a carbon date of 1735, predating every known treasure hunt on the island. Rick, Alex, Doug Crowell, and researcher Corjan Mol travel to Portugal to investigate Templar connections, visiting sites that mirror features found on Oak Island. The Garden Shaft becomes the team's new obsession.
