One of the most prolific areas for finding gold in
Wyoming is around the
South Pass area where many gold deposits have been found over the years.
Some of these deposits are measured in the millions of ounces. The state legislature in their infinite wisdom has placed the
Carissa Mine with
Wyoming’s version of
Disneyland so it will never be developed although there is still from $1 to $5 billion worth of potential gold reserves that could be recovered from this deposit during a time of national financial crisis. The mine could also provide hundreds of jobs. Unlike the Abitibi and other
greenstone belts in
Canada the area around
South Pass remains largely unexplored.
Dan Hausel, a geologist has mapped hundreds of gold anomalies over the past thirty years in the South Pass area. The area is a granite-greenstone belt where Hausel mapped over 450 square miles in five field seasons while he was living in a tent. Significant potential is there for iron and gold deposits as well as the possibility of finding colored gems as in the past the area has already produced specimens of aquamarine and diamond. After bringing fame to the Wyoming Geological Survey Dan retired in 2007, and moved to Arizona.
Oregon Buttes is another area having a huge potential in both paleo-placers and conventional placers.
Geologists consider the buttes to be one of the largest deposits of gold in
North America.
The source of all this gold is unknown, but is presumed to be from the
South Pass deposits where it was eroded and later deposited at the buttes.

In 1870 the army established
Camp Stambaugh near
Atlantic City to protect the miners from the Indians, but many of the soldiers deserted to hunt for gold in the area. By 1872 there were twelve stamp mills operation in the area although hostilities drove the miners from the
South Pass area until 1882 with the signing of the Treaty of Five Nations. The
South Pass area holds many significant hidden and visible gold structures located in a shear zone with the Carissa Mine being the richest.
This is an intensely deformed zone of iron oxides where the primary shear zone ranges from 1.5 to 80 feet wide. The deposit at Carissa is similar in many respects to the Homestake mine in Lead,
South Dakota.
There is plenty of geological evidence this shear zone extends to great depths under the Carissa mine.
Gold was first discovered in Wyoming in 1842 by one of the mountain men working for the American Fur Company, but it wasn’t until 1855 when gold mining started in 1855 when a group of gold miners came to South Pass from the goldfields of California, Later in 1861 another group of miners commenced mining the placer deposits along Willow Creek. The next discovery was in 1863 when another group of miners discovered the placer gold deposits at the Oregon Buttes.
According to the United States Geological Survey (USGS) Oregon Buttes comprises one of the largest undeveloped gold deposits in the United States. The gold at the buttes is thought to have its origin in the greenstone belts found at South Pass.
Western Wyoming contains most of the gold deposits in the state although it is likely that some gold can be found in northeastern Wyoming where it joins the Black Hills of South Dakota.
Gold isn’t the only treasure
Wyoming holds, some of the finest
jade in the world is also found in
Wyoming.
The jade occasionally has specks of gold imbedded in the jade making a beautiful specimen.
