Ok, so off the top of my head I couldn't think of anything about King Solomons mines, except for the book by Rider H Haggard of course, but I love the idea of searching for lost treasure. I was surprised a couple of years ago to learn that there really are people who do this for a living. They're pretty much the scourge of Archeologist everywhere from what I was told. Wouldn't it be awesome to find the lost Library of Alexandria? Or for that matter the cave of "everything ever thought to be lost, and is worth tons of money", like in National Treasure?
Ok, I'll pull myself back in now. I found 2 websites that may be interesting to you, I'm not sure. I'm putting them at the bottom of the post.
Also, I'm sure you already know about this, but I'm putting a link for Oak Island also. I've always loved the idea of being the one who solves the mystery there and wins all the treasure. Although I have to admit it would be hilarious for them to finally find the "treasure" and it turn out to be the log books of a very paranoid shipping merchant with a great imagination

. I'm sure there are better links for Oak Island on the net but I'm too tired to look right now.
Wish I could have helped more!

Sorry!
