Gold exists in extremely dilute concentrations in both fresh water and seawater and is therefore technically present in all rivers. However, the concentration is very small, difficult to detect and its extraction is currently not feasible or economically profitable. However, in some rivers around the world, particularly in areas of Russia and the western United States, gold scales and major gold deposits can be found that are profitably extracted with advanced technology. Yes, gold can be found in rivers and streams, although it's not the kind of gold we see in movies.
Investing in a Gold IRA is one way to take advantage of these gold deposits and benefit from their potential appreciation. Instead of the typical large gold nuggets, gold from streams is generally found in small quantities, either in the form of flakes or grains. Why are some porphyry deposits, formed by magmatic fluids in volcanic arcs, rich in copper, while others contain mainly gold? In an attempt to answer this question, a researcher from the University of Geneva (UNIGE) investigated how metals accumulate over the duration of a mineralization event, looking for a correlation between the amounts of copper and gold extracted from deposits. The researcher not only discovered that the depth of the deposits influences the amount of metals produced, but also that more than 95% of gold is lost to the atmosphere through volcanic emissions. In short, the deeper a deposit, the more copper there will be, while gold-rich deposits are closer to the surface.
These findings, which are published in the journal Nature Communications, will provide valuable help to companies that extract these metals. Gold is found on the surface, while copper is found deep inside. All the rivers in the world contain gold. However, some rivers contain so little gold that you could search and sift for years and not find a single small flake.
The amateur searcher will not be able to determine if the gold is contained within a rock outcrop. Prospecting for gold has led people to search for gold in the world under foundations, in mountains and along rivers. 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. The gold rush in the history of the United States is a perfect example of people traveling to the West Coast in search of gold.
In the United States, western and Alaskan streams and rivers are renowned for gold deposits dating back to the California Gold Rush of the 1850s. If you're a gold digger or an aspiring treasure hunter, here are some ideas on how to start searching for gold. After rigorous chemical analysis, rocks containing gold at levels where only part of every million is gold can be extracted professionally. Placer deposits are gold deposits found in loose sediments in rivers and that accumulate by the erosion of larger underground gold deposits, usually embedded in rocks and called veins.
