How To Prospect For Gold

This is over a pound of gold we recovered one day. Nugget patches we encountered like this were fairly common. Unfortunately only a few acres were available to us on this property.

As with narrow gulch properties, which can be phenomenally rich they do come with constraints.

Environmental laws are in place to protect our water resources. You have to choose your properties and the resources it offers carefully.

Glacial gold deposits are notoriously difficult to contain the silty water if you disturb the underlying bedrock gravel deposit. The slope and direction of the bedrock will determine your mining plan. Turbidity of the groundwater is an especially important factor to stay on top of. Groundwater dynamics processes need to be addressed constantly.

Depending on your mining plan. One way we have been able to keep this in check is to keep a series of sumps on the uphill side of the area to be mined to control the incoming groundwater before it is contaminated with silt. If you have room, an irrigation type sprinkler system can be installed to help distribute the water back into the aquifer system downstream. This also is a source of makeup water if needed, for your recovery plant.

Prospecting For Gold Gold In USA

Anyone who pans for gold hopes to be rewarded by the glitter of colors in the fine material collected in the bottom of the pan. Although the exercise and outdoor activity experienced in prospecting are rewarding, there are few thrills comparable to finding gold. Even an assay report showing an appreciable content of gold in a sample obtained from a lode deposit is exciting. The would-be prospector hoping for financial gain, however, should carefully consider all the pertinent facts before deciding on a prospecting venture.

Only a few prospectors among the many thousands who searched the western part of the United States ever found a valuable deposit. Most of the gold mining districts in the West were located by pioneers, many of whom were experienced gold miners from the southern Appalachian region, but even in colonial times only a small proportion of the gold seekers were successful. Over the past several centuries the country has been thoroughly searched by prospectors. During the depression of the 1930's, prospectors searched the better known gold-producing areas throughout the Nation, especially in the West, and the little-known areas as well. The results of their activities have never been fully documented, but incomplete records indicate that an extremely small percentage of the total number of active prospectors supported themselves by gold mining. Of the few significant discoveries reported, nearly all were made by prospectors of long experience who were familiar with the regions in which they were working.

Locating Gold And Other Minerals

Technology has taken much of the guesswork out of mining, mountain ranges are still notoriously difficult environments in which to hunt for valuable minerals. Various methods used to draw a picture of the underground environment, including the measurement of gravitational and magnetic fields, are easily thrown off by factors such as changes in topography height, surrounding temperature, and barometric pressure.

Now Prof. Lev Eppelbaum of Tel Aviv University's Department of Geophysics and Planetary Sciences has developed a new method for processing and analysing complex environments in the face of these challenges. Combining new physical-mathematical approaches with their own advanced software -- which brings together all available analysis in the same three-dimensional image -- the researchers were able to overcome the difficulties posed by mountainous regions, successfully uncovering new mineral reserves.

How To Mine Placer Gold

Placer gold has tantalized many a person who has tried his luck and skill in the hope of striking it rich. Separating gold from embedded materials is basically simple, and can be done effectively on nearly any scale, depending upon the deposit and the capital available for investment. The final product is consistently in demand at a relatively stable price. Historically, however, one must be advised that rewards for the majority of small-scale miners--those who operate "on a shoestring"--have been depressingly small.

First of all, the placer miner must know where placer deposits are located and he must have the technical knowledge to extract the gold. Additionally, he must face problems of land ownership, water supply, and water pollution, all of which have grown in complexity with the population. The costs of labor and equipment are relatively high now, although this may not seem significant to an individual mining a small deposit. Secondhand equipment may become available at relatively low cost because of a slowdown in construction or as surplus at the end of a war. By taking advantage of such opportunities, one can sometimes make an otherwise unprofitable operation successful, at least as long as the equipment holds up.

Sluicing Instructions

After you have located a promising deposit of gold-bearing gravel, walk along the stream bank and look for a place where you can set up your sluice box. You should search for a spot where the current is moving quite swiftly. Once you find such a place, set your sluice box directly in the current so that the box is filled with water almost to the top.You can often compensate by placing the sluice box so that the upper "input" end is slightly higher than the lower "discharge" end. If the sluice box is somewhat unstable in the current, position a few rocks around the outside of the trough to brace it.

Sometimes you will not even need the "rock brace," as the first few buckets of gravel placed into the sluice box will provide just enough stability to weigh it down.
