Nevada Gold ( the graphic in the link blows up for easy viewing.)
I have added this for a couple of reasons.
First, it shows interesting details about Nevada.
Second, I had geologists all over my land because it was supposed to be ground zero for analogous deposits. One of the geologists visited the site in Nevada to get comparative data. He said my land sits on a 300 million year supervolcano laying on its side. It stretches for 15 plus miles. The gold thus is harder to find and there hasn’t been much follow up interest by the companies, yet. However, if there is anything like the one trillion US in Nevada I am screwed.
