It appears, from the article, that something of great value was unearthed and the presence of the security vehicles along with Armored type cars indicates, at least to me, that not only is there a cover-up going on but that the government did, indeed, find the treasure trove of Union Gold. Naturally, those responsible for identifying the site location would be kept out of the loop but I hope, in the end, they are able to prevail and get what's due them. I, too, would be interested in knowing what they found and removed, from that hole in the ground. I'd also love to know who ended up with the treasure.
It's also sobering to think just how much uncovered wealth, gold, coins etc are buried and lost forever or until someone comes around and happens upon it.
