Continuing their attempt to reveal the origins of the Oak Island mystery, the Laginas and their team build off scientific revelations from seasons past which indicate that large silver and gold reserves lie deep in the Money Pit area. Applying cutting-edge technology, they look to pinpoint the exact location of the legendary treasure with large-scale dig operations that may include constructing new tunnelling and shafts. The team’s reach broadens with wider exploration across the swamp and extends into Europe, all in the hope of concluding the mystery.
