Gold Veins And Other Gold Deposits
Nearly all workable gold deposits are veins, lodes, shear zones, stock works, saddle reefs, and replacement ore-bodies, which are connected with intrusions of granite, syenite, diorite, and other igneous rocks of an acid or intermediate variety. It is said that about 80% of the worlds profitable gold mines are closely associated with acid and intermediate porphyries.
Sift Through The Dirt
Sifting through the dirt will be physically demanding, so make sure that you dont hunch your back the entire time you are digging. Being in this position can cause lower back pain. Bend your legs and use them for when you move up and down. Try not to bend at the waist.
Scoop the sand or dirt into your pan and start sieving through it. Digging for gold could take several hours, and you may not even find much during this time. You will need to use the water to help rinse the sand away and see what is left behind.
Gravel may be a little more difficult. You will have to sift through some of the larger pieces with your hands to check if you have any gold in the mix.
You will find yourself in a crouched position sifting through all the sand and dirt. If this seems like something you arent capable of doing for more than an hour, you may want to try something else or complete this activity in short spurts. You dont want to wake up the next morning sore and stiff.
Gold Geology And Ground Color Changes
Color changes in the soil are another indicator of a contact point. Depending on how much bedrock is exposed in an area, you may or may not be able to easily identify contact points where different rock types come together, but you will be able to see where soil color changes. Since soil is composed of the host rock, even a small change in soil color can be an excellent indicator of a contact zone.
Some color changes can be very readily apparent, while others can be quite subtle. You arent looking for small areas with minor change here, you want to try and identify distinct lines of different soil types.
These contact zones may be generally short, but sometimes they will run in a generally straight line for many miles. You may also have success finding new gold bearing areas by locating productive mines and then noting a color change that extends off from the mine. There may be valuable gold deposits in a nearby drainage that are an extension of the same contact zone that occurs at a well-known mine just over the hill.
Remember to always study the different types of gold geology and you will soon learn that there are plenty of areas that have not yet been found.
find gold nuggets with a metal detector also have high iron content.
This is the reason that it is recommended that you use metal detectors specifically designed for detecting gold nuggets, since they are specifically designed to handle these highly mineralized, iron-rich environments.

How Gold Ended Up On Earth
After the Big Bang occurred, there were only three elements: hydrogen, helium, and lithium. Since gold is not made of any of these elements, and instead is its own element, where did it come from?
The current theory involves a neutron star collision: a large abundance of gold and platinum has been observed in the electromagnetic spectrum of a neutron star collection, which would explain how gold came to Earth millions and millions of years ago.
Where To Find Gold In The Uk
Gold has been mined in the UK since the time of the Romans. Peak production of gold was between 1860 and 1909, when around 3,500 kg was found. The largest concentrations of gold in the UK are in Scotland, North Wales, and southwest England.
Today in Northern Ireland, for example, there is an estimated 15-20 million ounces of gold in a 30 mile gold trend at Clontibret in County Monaghan. Also in Cornwall, the South Crofty mine near Camborne transformed from an extremely lucrative tin mine to a gold mine when traces were found via exploratory drilling. Scientists believe that this gold mine may be more gold-rich than some of Californias most famous mines.
Besides gold mines, once in a while large stashes of ancient gold coins from the Romans are found at sites around the United Kingdom via metal detection.
No matter where it is found, the UK, as many other places in the world, is rich in gold and other precious metals.

Knowledge Of Laws And Property Ownership
Today’s prospector must determine where prospecting is permitted and be aware of the regulations under which he is allowed to search for gold and other metals. Permission to enter upon privately owned land must be obtained from the land owner. Determination of land ownership and location and contact with the owner can be a time-consuming chore but one which has to be done before prospecting can begin.
Determination of the location and extent of public lands open to mineral entry for prospecting and mining purposes also is a time consuming but necessary requirement. National parks, for example, are closed to prospecting. Certain lands under the jurisdiction of the Forest Service and the Bureau of Land Management may be entered for prospecting, but sets of rules and regulations govern entry. The following statement from a pamphlet issued in 1978 by the U.S. Department of the Interior and entitled “Staking a mining claim on Federal Lands” responds to the question “Where May I Prospect?”
Core drilling for gold: Core drilling the Bend massive sulfide deposit, located in the Medford District of the Chequamegon National Forest, Michigan. It is a small, metal-rich sulfide body hosted by Early Proterozoic Penokean volcanics. The mineralized horizon subcrops beneath 100-120 feet of glacial cover, and consists of massive pyrite with varying amounts of chalcopyrite, tetrahedrite-tenantite, bornite, arsenopyrite, chalcocite, and rare gold-silver tellurides.

At What Depth Will You Find Gold
There is no specific depth at which gold can be found. Examples of this are the Welcome Stranger the largest gold nugget ever found which was retrieved at only 3cm below the surface. Oppositely, gold mining operations today take place at a depth of around 3km under the Earths surface.
The depth at which you will find gold also depends on whether you are conducting small-scale prospecting operations focused on placer gold or large-scale mining processes.
Lets look at these two types of gold, and how they are different from one another!

Where Is Gold Found In Nature
Gold is found throughout the earth and the sea. There are natural spots on the earth that contain more amounts of gold. Gold is commonly found within rock and granite in the earth.
In its natural form, gold is very irregular and not refined, as it is normally seen in its finished state. Gold is found in many forms. These forms include plates, large spongy pieces, scales and microscopic pieces. In large cavities and reefs, gold can be found in large quantities resembling the shape of a crystal. This is because there is enough space for it to grow into this enormous shape.
When gold is sought after in rivers, it is found where the water velocity has lowered. The lowering allows for the gold to fall out of the current of water. More times than not, gold will be found with other precious and non-precious metals. The gold must be extracted from these metals. The presence of gold in sea water is believed to be far greater than the presence anywhere else on earth. Despite this, it is not sought after because the cost of retrieving the gold would be more than the cost of the gold that is retrieved.
What River In California Has The Most Gold
The Merced River is an important gold-bearing river in northern California. The river flows through the heart of the Mother Lode, the richest gold regions in California. There are several miles of the Merced River near Briceburg that are open to recreational gold panning within the Merced River Recreation Area.

Homestake Mine South Dakota
Before the Homestake Mine ceased operations in 2002, it was the largest and deepest gold mine in North America. This historic gold mine produced close to 44 million ounces of the precious metal. The Homestake Mine is also famous because of scientific experiments that took place there in the mid-60s, in a deep underground laboratory. The Homestake experiment was conducted by Raymond Davis Jr., who was the first to observe solar neutrinos. This earned him a Nobel Prize for his pioneering contribution to astrophysics.
The South Dakota gold deposit was discovered in 1876, during the Black Hills Gold Rush. The gold ore mined here was actually only considered low grade, but the body of material was so large that mining operations were highly successful. As well as gold, 9 million troy ounces of silver were produced. The Homestake mine was the longest continually operating mine in United States History and made huge contributions to both the economy and scientific research.
Bedrock Formations And Pay Streaks
Prospectors should be aware that any rock and bedrock can boast different qualities and gold-trapping properties, crevices can open length-wise or in other shapes and forms, but they make some of the most likely locations to find gold.
When looking for gold traps, it is also essential to keep in mind that they will likely be located by a water force that would have swept off lighter materials, consequently trapping valuable particles.
Lastly, pay streaks are just larger gold traps in which high quantities of gold particles have concentrated. Pay streaks are formed along a river or stream, just after the course of water changes, and the pressure diminishes, which causes the gold to drop off.

Where To Find Platinum
The high value and usefulness of the platinum family of metals suggests a careful search for new sources. Small quantities are produced from gold placers, and important amounts as a by-product in the refining of the copper from the ores of the Sudbury District. Formerly the main supply came from the placers of the Ural Mts., Russia, and South America . In those countries, it has also been found in place, associated with chromite in serpentine and peridotite rocks. Some large masses of platinum have been found, one weighing 23 lbs. It should be looked for in serpentine, wherever the rock is mineralized, and particularly where chromite is found. Olivine gabbro should also be sampled and assayed. In South Africa has been discovered a great platinum-bearing belt from Cape of Good Hope through Southern Rhodesia, but the most promising part of this belt is in the Transvaal. The platinum has been found in a great variety of rocks and minerals, including sulphide ores, quartz veins, norite, peridotite, and in the diamond formations. As platinum is very heavy , it will easily show in panning.

How Much Gold Has Been Found In The World
About 244,000 metric tons of gold has been discovered to date . Most of that gold has come from just three countries: China, Australia, and South Africa. The United States ranked fourth in gold production in 2016.
All of the gold discovered thus far would fit in a cube that is 28 meters wide on every side.
Most of the gold that is fabricated today goes into the manufacture of jewelry, but gold is also an essential industrial metal that performs critical functions in computers, communications equipment, spacecraft, jet aircraft engines, and a host of other products.
What is “Fool’s Gold?”
Fool’s Gold can be one of three minerals. The most common mineral mistaken for gold is pyrite. Chalcopyrite may also appear gold-like, and weathered mica can mimic gold as well. Compared to actual gold, these minerals will flake, powder, or crumble when poked with a metal point, whereas gold will gouge or indent like soft lead. In addition, actual gold will leave a golden yellow streak when…

Slope And River Speed
In simple terms, the faster the speed of the river, the less light gravels and sands will remains attached to the streambed. In other words, gold that travels down a fast-flowing river is likely to be closer to the surface than that in a slower river.
One way of quickly assessing the speed of a river during the flood stage is how much exposed bedrock there is. If a river has a lot of exposed bedrock, you can be somewhat more certain that the gold is close to the surface.
Similarly, if the river has a steep downhill slope, it will help remove much of the streambed material and leave the gold closer to the surface.

Minerals Associated With Gold
Heavy hard minerals that concentrate with the gold are often a guide. The commonest are magnetite and ilmenite , garnet , zircon , and monazite . Tinstone is often found in gold placers, and may be a valuable by-product. Platinum and osmiridium should not be overlooked they are more valuable than gold.

See below for Gold Locations by individual State
Naturally occurring gold can be found in almost all fifty states. This gold may be still embedded in rock, known as “lode gold”, or it may have been deposited in a placer after weathering from the host rock — or it may be found in plant tissues, or seawater, or even present in minute quantities in beach sand. If your interest in gold is more than academic, the trick is to find locations with enough gold to make it worthwhile to try to recover some of it.
The states in which major amounts of gold have been found are: Alabama, Alaska, Arizona, California, Colorado, Georgia, Idaho, Michigan, Montana, Nevada, New Mexico, North Carolina, Oregon, South Carolina, South Dakota, Tennessee, Texas, Utah, Virginia, Washington, Wisconsin, and Wyoming. Although the historic records are generally not very good, small amounts of gold have also been found in Indiana, Maine, Maryland, Missouri, New Hampshire, Oklahoma, Pennsylvania, Rhode Island, and Vermont — which taken together with the big producers means that in three out of every five states, you have a decent chance to find a little gold for yourself.
