The gravels have been 6 to 10 toes deep, and gold occurred as flatten nuggets and flakes close to bedrock and within the sandy and gravel layers overlying skinny clay-wealthy, false bedrock, zones. All of that lineation you might be taking a look at on Google Earth is the metamorphosed sedimentary and volcanic rock beds that have been tilted ninety levels (roughly) and now sitting on end. Examine the area at an eye fixed altitude of 50,000 to 10,000 feet on Google Earth and you will notice outstanding rock lineation that traits roughly E-W to E-NE in hills surrounding Atlantic Metropolis. Transfer your stylus to 42°29’10"N; 108°40’18"W just east of Atlantic Metropolis for an excellent aerial view of lineation. In line with historical records, the primary report of gold at South Pass was made by a trapper with the American Fur Firm in 1842. The location of his discovery is believed to have been Strawberry Creek, east of Rock Creek. Throughout a latest reconnaissance research of the property, the writer also recognized a possible extension of the mineralized zone that had been down-dropped to the east of the identified mineralized zone, indicating that this deposit has even better potential. After beginning reconnaissance at South Move in the 1980s, I was awarded a sequence of COGEOMAP grants from the US Geological Survey, which led me to a practically decade of geological mapping of the 400 mi2 greenstone belt, its mines, and gold.

For example, the South Move greenstone belt is flanked by two giant paleoplacers identified as the Twin Creek (Antweiler and others, 1980) and Oregon Buttes paleoplacers (Love and others, 1978; Hausel and Love, 1991), and large areas of the greenstone belt are also overlain by extra paleoplacers. Nephrite has been discovered at a variety of localities in central Wyoming including the Prospect Mountains of the southern Wind River Mountains, the Granite Mountains, the Seminoe Mountains, the northern Laramie Mountains, and has also been found in fanglomerates derived from these areas. Gemstones are present in a wide range of geologic settings and may be the results of crystal progress and/or alternative during regional metamorphism producing jade, sapphire, or ruby; magma cooling producing peridote or aquamarine phenocrysts or megacrysts; partial melting at nice depths where diamond xenocrysts may be captured and delivered to the earth's surface; or just merely low temperature silica alternative of fossils and wood at the earth's surface. Ogden, P.R.,1979, The geology, Reviews Of The Best Gold Ira Companies major component chemistry, and petrogenesis of the Leucite Hills volcanic rocks, Wyoming: PhD dissertation, University of Wyoming, Laramie, 137 p. I mapped the 2 largest diamond-bearing kimberlite districts within the US (Iron Mountain and State Line) and later mapped the most important lamproite field in North America (Leucite Hills).

The diamond-bearing kimberlites in the State Line district were initially acquired by firms in the late 1970s and early 1980s, and gem-quality diamonds as much as 28.Three carats in weight have been recovered. A number of different nuggets ranging in weight up to 5 ounces have also been described (Hausel, 1991). Most nuggets in the State are rounded typical of detrital transport, although Day and others (1988) report slivers and hairs of gold from gravels within the Lewiston district. The gold was reported to occur as flakes, small particles and uncommon rounded nuggets with a typical fineness of 0.840 to 0.900 (eighty four to 90% pure gold). During a 1987 mining operation on Smith Gulch (a tributary of Rock Creek), prospectors Hank Hudspeth and Buddy Presgrove recovered about 20 ounces of gold per week, and periodically hit pay streaks yielding 20 ounces in a day. The two recovered about 20 ounces of gold per week in an space that arm chair prospectors claimed had no gold or was all ready mined out. In 2015, RC Mineral and Rock, LLC employed me to examine their Rock Creek gold placer at South Move, Wyoming. Without the usage of dredging, trommel plants, pumps, or hydraulic mining, placer operations within Rock Creek would have been limited and largely ineffective due to the stream’s gradual gradient (2°) that is not favorable for gold restoration by sluice.
