The treasure is the amount of $$$ the brothers have generated off of the program. They've spun off a couple additional programs and I see Marty is an executive producer on multiple shows now. I understand they own about 80% of the entire island now. Additionally, they built a Knight's Templar style castle winery in Traverse City (Mari Vinyards) named after their mother. It's a nice place and has a subterranean vault where their wine is aged. When we were there, Marty's son was the manager. Of course, Oak Island Merch is in the giftshop, but we had the opportunity to meet Marty that evening and for all his fame and fortune, he's a remarkably down to earth guy. Engineer who also holds a law degree from U of M. Made his original millions building and selling windfarms to consumer's. Brilliant guy but never mentioned a word of it. His staff told us his history and raved about working for him.
