These areas are mainly found in Alaska, Arizona, Arkansas, California, Colorado, Florida, Idaho, Louisiana, Mississippi, Montana, Nebraska, Nevada, New Mexico, North Dakota, Oregon, South Dakota, Utah, Washington and Wyoming. Gold nuggets can't be found anywhere, as most locations haven't seen the geological stability needed to form gold nuggets. In short, gold nuggets are formed by geological processes that need time to build the nugget. Gold nuggets are more likely to be found where thick gold has been found before.
The next generation of detectors arrived around 1970 with transmission-receiver technology. The TR detector used a concentric double coil with a transmitter coil on the outside and a receiver coil in the middle. It worked something like a radar, sending a pulse to the ground and reading the resulting bounce. When a metal object interfered with the rebound, it gave a signal to dig.
Constant noise was eliminated and, for the first time, there was discrimination. The latest generation of detection machines for the non-specialist operator arrived around the 1990s with Very Low Frequency technology. Most current detectors are of the VLF type, except those with specialized pulse induction. VLF machines do not send a radar pulse but a constant signal in the shape of a truncated cone, like a curtain of underground flow lines.
When this curtain is disturbed by a conductive metal object, it generates an audible signal. Below are two findings, a silver conch and an unmarked hand-cast gold ring. Both were found with a VLF and a four-inch coil, on the same day about ten feet away. Below are some miscellaneous finds from some ancient sites.
These include a dog license issued by Yuma, AZ in 1899, an Elks Club Bazaar token from 1913 and, on the bottom left, a souvenir pin from the 1939 World's Fair in New York City. All this was found in the course of excavating all targets in search of some gold. All the rivers in the world contain gold. However, some rivers contain so little gold that you could strain and sift for years and not find a single small flake.
The hobbyist seeker will not be able to determine if the gold is contained within a rock outcrop. Gold can be found on almost every continent of the earth. It also exists in trace quantities in seawater and in the human body. Gold exists in extremely dilute concentrations in both freshwater and seawater and is therefore technically present in all rivers.
However, the concentration is very small, difficult to detect and its extraction is not currently feasible or economically profitable. However, in some rivers of the world, particularly in areas of Russia and the western United States, significant gold flakes and gold deposits can be found and extracted with advanced technology with profit. Yes, gold can be found in rivers and streams, although not the kind of gold that we see in movies. Instead of the typical large golden nuggets, gold from streams is usually found in small quantities, either in the form of flakes or grains.
While Kolar's gold deposits have been closed for several years due to declining investment returns, this area of India is still believed to contain very rich gold deposits. If you are a gold digger or an aspiring treasure hunter, here are some ideas on how to start digging for gold. If you live in a state where at least some gold has been mined, there is a good chance that you can find state or district reports on where gold has been found. If you take a look at the gold prospecting industry, you'll soon notice that some types of gold are getting more attention than others.
Prospecting for gold has led people to search the world for gold under rocky rocks, within mountains and along rivers. In the United States, western and Alaskan streams and rivers have a reputation for gold deposits that date back to the California gold rush of the 1850s. This is another technique used when water is scarce and, although it is not effective when it comes to trapping tiny gold, it can be used to recover gold nuggets and larger pieces of gold. It could be said that gold adheres to existing gold particles in a process similar to that which salt or sugar dissolved in water crystallizes when a nail is placed in the solution.
Suction dredges can process loads of material, and there are real stories of gold miners who can recover ounces of gold every day, operate a suction dredge by themselves. Seawater contains gold in even more dilute concentrations, measured in parts per trillion, and according to the National Oceanic and Atmospheric Administration, the world's oceans contain 20 million tons of diluted gold. In these two regions, South Africa has the highest concentration of gold, and the city of Johannesburg is built on the largest gold deposit in the world. Low-frequency machines favor gold nuggets and iron, while higher frequencies are better for small finds, gold flakes and small pieces of jewelry.
You don't need to take a week off to roam the dry washes of Arizona for gold nuggets when gold is buried a hundred meters from your living room couch if you live in an older populated area. . .
