Gold in Moffat County, Colorado
March 1999 by Edgar B. Heylmun, PhD
The area of interest in this article is in eastern Moffat County, located in northwestern Colorado adjacent to the Wyoming line. It is a high, sagebrush prairie which ranges from 6,200 to 7,200 feet in elevation, north and northwest of the county seat of Craig (pop. 8,000).Detecting For Gold—Are You Up For It?
Over the years that I have been detecting for gold I have had many of the same questions come up. I decided to write this article to hopefully answer some questions that a person wishing to detect for gold may have.
Detecting for Gold in Australia—The Kimberley Trip
The hair stood up on the back of my neck when I saw this, especially the nice patches of wash in the bottoms of the gullies, a sure sign of an auriferous source being nearby.
Placer & Lode Gold Deposits

Selenium, Mercury and Suction Dredging—Studies Contradict CA State Water Resources Board
Federal and state regulatory agencies often cite mercury and methyl mercury in our waterways as a major factor for further restrictions on placer mining, and on suction gold dredge mining, in particular. However, these regulatory agencies are minimizing selenium and its neutralizing effects.
Sandstone Silver in Texas
Sandstone silver deposits are found at several places near Van Horn, West Texas. The region is in the Basin Range province, which is characterized by low mountain ranges separated by broad desert valleys. Most of the region receives less than 10 inches of rain per year, barely enough to support scrubby desert vegetation. Van Horn (Pop. 3,000) is 121 miles, by highway, east of El Paso.
Melman on Gold & Silver
Perhaps the heart of our pro-gold thesis is this consideration: governments are inherently inefficient, they attempt to provide services far beyond their genuine fiscal ability and these trends result in deficit financing, growing debt levels and ultimate “watering” down of currency values.
Enrichment of Mineral Deposits by Weathering—Part II
While both zinc and lead deposits also are enriched by the surface weathering process, in part two we will look at the enrichment process for copper and also gold deposits, and at the interpretation of leached outcrops to figure how rich the concentrated deposits below them may be.
