The quest to solve the 231-year-old Oak Island mystery has transitioned from speculative digging to precision science. In a landmark week for the “Fellowship of the Dig,” archaeometallurgist Emma Culligan confirmed the discovery of gold bonded to organic timber at a depth of 55 feet, marking what experts call the most significant chemical evidence in the history of the search.

The discovery was not made in the soil or the water, but within the very wood of the Garden Shaft. Following a methodical probe-drilling operation, Culligan used a handheld XRF (X-ray fluorescence) device to scan fragments of the shaft’s original timber lining. The “Sponge” Effect: 100% Certainty The results, presented in the Oak Island “War Room,” stunned the team. The scan returned a 0.11% gold concentration—a figure described as “meaningful and measurable” in archaeometallurgy.

“The wood acts like a sponge,” noted Rick Lagina. Over decades, the timber has been submerged in groundwater that has consistently tested positive for trace gold. According to Culligan, the 0.11% reading is not background noise or contamination; it is the result of gold migrating from a nearby, high-concentration source and bonding to the ancient wood. “It’s gobsmacking,” added metal detection expert Gary Drayton.
The Geometry of Shaft 2 While the lab work confirmed the presence of gold, the field crew utilized dendrochronology (tree-ring dating) to fix the location of the elusive Money Pit. Samples pulled from what was suspected to be Shaft 2—the oldest known searcher site, dating to 1805—were sent to an independent laboratory.

The results confirmed the trees were felled in 1796, a date consistent with early 19th-century construction seasoning. This scientific anchor has allowed the team to calculate the exact position of the original Money Pit with unprecedented precision. “The Money Pit now falls within a 14-foot radius of known, confirmed fixed points,” reported Jack Begley. For a project that has spanned over two centuries, reducing the search area to a mere 14 feet represents a monumental operational shift.
The Sage’s Success: Shaft 9 and the Sluice Simultaneously, veteran searcher Dan Henskee’s decades-long theory regarding a southern sluice system has been vindicated. Excavation near the shore unearthed a wooden sluiceway, protected by “puddled clay,” that remains functional after 160 years.
By tracing this channel, the crew located Shaft 9 (circa 1863) and a horizontal tunnel that points toward a section of the island never before penetrated by modern machinery. This “virgin ground” is now a primary target for the remaining weeks of the season. Converging Evidence The team is no longer relying on “gut feelings.” Three independent lines of inquiry—chemistry in the Garden Shaft, biological dating in Shaft 2, and hydraulic engineering in Shaft 9—have converged on a single underground system.
“Science was always supposed to be a real component of this search,” Rick Lagina stated. “This single week proved it.” As the radius around the Money Pit closes to its smallest point in history, the fellowship remains hopeful that the next drill hole will finally reveal the source of the gold saturating the island’s depths.
