Roger Fortin reports the Garden Shaft has reached 87 feet but water is infiltrating at set 16. The plan is to drill nine holes above the water source and inject urethane to seal it, then continue deepening to approximately 100 feet where the crew should breach the seven-foot-high tunnel running east to west toward the Baby Blob. That tunnel has been carbon dated to as early as the 17th century. Once reached, Dumas will begin horizontal drilling up to 40 feet in every direction to search for evidence of valuables. In the War Room, Dr. Lukeman presents fluorescence spectroscopy results from Money Pit water samples, a technique using high-powered ultraviolet light to excite molecular compounds and detect organic material that would indicate human activity. Sample L16 Deep, believed to open into the large void at depth, registers what Dr. Lukeman describes as anomalously high levels of organic material. Dr. Spooner asks whether a tunnel could lead to or intersect the void, and Scott says they need to drill at the opposite end to lower a camera and look for wood.
Borehole KL14.5, drilled 10 feet northwest of L16 to access a different section of Aladdin's Cave, breaks into the cavern at 142.5 feet where the void extends down to 153 feet. As Terry and Moya oversee the operation, Mike confirms the opening and the casing is pulled back to allow a camera down. An Inuktun Spectrum 120 high-definition camera is lowered into the space and reveals what looks like the head of a bolt. The team also detects a current pulling sediment past the lens, suggesting the cavity is connected to flowing water. They decide to return in a few days for sonar imaging once conditions settle.
At the Interpretive Centre, Carmen Legge examines artifacts from the circular feature on Lot 5. The first piece he identifies as a handmade scupper nail, used to secure the drainage holes found on ships, which he dates from the early 16th century to the early 17th century. Emma confirms it contains 0.2 percent chlorine, indicating exposure to salt spray. Carmen then studies a piece with a high-angled handle and identifies it as a ladle, confirming it as a maritime artifact consistent with the Phips timeframe. Peter notes the connection fits with what the team has been finding across Lot 5. On the same site, Jamie recovers a strap hinge fragment and Helen unearths a large rose head nail she dates to the 1600s, another piece Emma will test for chemical alignment with the Phips collection.
A storm then strikes the island and floods the Garden Shaft with 30 feet of water. Marty, Craig, and Scott meet with Roger the following day to assess the damage. Roger reports that pumping is underway but the engineers will need to evaluate the situation before Dumas can safely resume deepening. Marty raises the possibility that the water may have reached the depth of the flood tunnel.
