Occurrences such as these have proven, time and time again, that gold possesses the attribute of maintaining significant value over time, something that cannot be said of unbacked, fiat paper money where every such issuance has eventually deteriorated throughout history into virtual worthlessness.

The Fire Assay of Fly Eyes
July 2002
Colorado-Utah-Wyoming oil shale was first reliably discovered to contain gold and silver by the U.S. Bureau of Mines in the 1920s. Although most of this vast shale resource, up to 1,000 feet in thickness, contained nil or barely detectable values, many brown shale samples fire assayed here over the past thirty years have yielded up to 0.02 ounces per ton (opt) Au and 2.0 opt Ag.
