Oak Island, does the answer lie in the Netherlands?

Today in De Telegraaf: For eleven years, brothers Ricky and Marty Lagina have been searching for a mysterious treasure on Oak Island, off the coast of Canada. Now, according to Dutch historical researcher Corjan Mol, a solution may be close at hand. Mol accidentally discovered a hidden crypt beneath the castle ruins of Valkenburg, filled with symbols associated with the centuries-old Oak Island mystery. He also found these symbols at other alleged Templar sites around the world. Mol draws a connection between Europe and Oak Island and suspects that people were willing to risk their lives for valuable treasures.
