I had been busy representing the Prospecting and Mining Journal this spring, but prospecting season finally arrived and I’ve been out digging for nuggets—I’ve even found a few. I know a number of prospectors who are armed with new metal detectors and headed to the hills to look for that precious yellow stuff.
He began hiking my way and was as astonished as I was when he saw it. Another high five moment! It makes you wonder how long this gold had just been sitting there on the ground.
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.

Placer mining, whether for profit or recreational purposes, involves separation of free gold from the gold-bearing sands (gangue) of alluvial deposits by methods using specific gravity. The free gold can vary from 17 to 19.3 in specific gravity terms, depending on the alloy mix, which is usually silver, but can be copper, lead, sulfur, tellurium, antimony, or mercury.
