So the PR stated the new tech spotted non-ferrous targets. I think it is extremely safe to assume they are either gold or silver targets even though it wasn't stated otherwise they wouldn't have gone to such time and expense to get that permit. Not to mention the expense of getting the site/crew/media ready to go onsite. They seem to be pretty sure of the tech and if so the stock will go crazy. Personally, I believe in Tim Reynolds and the tech.
