Conclusions of <strong>Oak</strong> <strong>Island</strong> Detection Program 1. During down hole surveys a great deal of interference occurred due to the presence of steel drill rods and casings in the area of the Money Pit. 2. Hole B24/W8 could not be used for down hole magnetic and EM surveys because it had steel casing to a depth of about 200 feet. 3. The down hole magnetic testing was not able to identify the inferred ½ inch thick iron plate drilled through at a depth of 198 feet in Hole B25 located about 30 feet from the detection holes. 4. The down hole EM testing (after allowance for magnetic effects) did not identify reliable anomalous features which may represent non ferrous metals. 5. The cross hole seismic tomography survey at the Money Pit defined the geological zones of soil and rock but would not have been able to define regular shapes of underground chambers or tunnels (if they were not collapsed) due to the complex and irregular subsurface conditions in the broken anhydrite zone. 57
