What time is it?.... IT'S XENOTIME!!!
 While we were diggin on the claim on Monday, my longtime friend (and co-owner) was getting into a nice pocket of gemmy smokies when he found a odd crystal we had never seen before. We suspected Zircon because of the crystal shape and it felt very heavy. After a specific gravity test it appears to be Xenotime. It is also on the heavy side of Xenotime which would suggest that the Yttrium in it has been replaced with a heavier mineral/element like Uranium or Thorite. It may have mild radioactivity. If I get the chance to test it for radiation I'll post results. If your wondering how to pronounce Xenotime here is a link with audio: Oxford Dictionaries
The crew and I just before the rare find. (I'm on the left)
