The "5, 95% reliable results" Loki refers to are PUBLISHED results. No proponent of an "ancient" explanation of the Oak Island enigma will refer to the "other" results which call the other 5 into question. There have been at least 14 conclusive tests performed on "coconut fiber" recovered from Oak Island; a few more returned results as "inconclusive", due to deterioration or contamination. Of those 14, 5 returned results as Loki described, 6 returned results "with 95% confidence" of dates 200-300 YBP (1670-1770), 2 indicated, "with 95% confidence" ages of over 10,000 years, and 1, "with 95% confidence" showed an age of approximately 100 years. These tests were performed on dozens of samples of coconut fiber, wood and other organic materials found over the years of about 1965 to the early 2000's, at several different labs, some no longer in operation. Thermo-luminescence tests performed on pottery shards found in the various pits indicate ages in a narrow range between 1740-1780.
My knowledge of these tests come from former associates at UNC, U of Chicago (where C-14/AMS dating was developed), and UVA, who performed many of the tests on items we recovered while doing field work as a student at ECU. They, in turn, have associates and colleagues at laboratories, including BETA Analytic and TRIUMF at Canada's National Lab. I have held hard copies of these test results in my hands.
