| Survey the location of the gold |
Gold prospecting is the act of searching for new gold deposits. Methods used vary with the type of deposit sought and the resources of the prospector. Although traditionally a commercial activity, in some developed countries placer gold prospecting has also become a popular outdoor recreation.
In the process of finding an area that has the gold prospecting, location survey process is very important. So that we can know the area contains a potential gold metal or not.
All gold mining either large or small mine to search for the existence of gold deposits in an area through a survey activities, either the survey the rock type or rock formation, and characteristics survey of the soil
Survey and identification process to find the location gold prospecting this is also done by surveyors in the world's largest gold mine
Simple prospecting for gold is normally done with a gold pan. A simple way to survey the early stages of searching for the location of the gold content, can find for gold content eluvial or commonly referred to as loose and free gold, which is a kind of gold in the form of granules. This method can be used in the survey to locate new gold deposits.
Genesis alluvial or placer gold deposits are formed by rainfall and sediment concentration of gold from primary gold occurrence. For millions of years, extreme weather has turned the mountains and hills that lead to the process of erosion and cracks in the rocks on the mountain or hill.
Then rock weathered and broken experiencing an erosion of natural processes, either from rainfall, earthquakes, or other natural events that cause the material to move down to the bottom of the hill and into the waters of the river area.
From these events, the metal ore mineral material will be detached from the rock that later became fine gold grains.
Ways and simple technique to look for gold prospecting or survey the location of the gold.
In find eluvial gold we need to do is find the location of mountain areas or hilly areas that have a strong granite or crystalline deposits and ancient mountains or hills.

After finding the location that will be carried out the survey, The first step we can look for watersheds or river bottom or base among the hills, as alluvial gold process occurs when water flows down from the top of the hill or mountain will carry the eroded material and rapidly toward watershed, or basin.
After finding the watershed, trying to do a survey of rock from the downstream or lower part of the river flow first. Do the panning to see any gold content or not. Gold panning process that most prospects in the flow of the river bend, because at the bend of the river usually gold ore often stuck there. we can try to pick or dig up soil sediment or sand from the river and then done panning with a pan, as well as other tool.

If the downstream not find a speck of gold in the process of panning, the panning process is done again in the stream that the top of the first panning area, and this step is done regularly and continues, if found traces of rock avalanches from the hills in the river, the identification process can be done by breaking some rock or panning avalanches.

If the river flow that there is gold content just being the first
location, or is found also on the upper flow of the river, it can be
inferred gold mineral deposits located in hillside location in the area
of the discovery of gold the last point. Later in the hills or mountains
can be searched quartz or rock avalanches that could be identified.
Prospectors for hardrock, or lode gold deposits, can use many tools. It is done at the simplest level by surface examination of rock outcrops, looking for exposures of mineral veins, hydrothermal alteration, or rock types known to host gold deposits. Field tools may be nothing more than a rock hammer and hand lens.
Hardrock gold deposits are more varied in mineralogy and geology than placer deposits, and prospecting methods can be very different for different types of deposits. As with placer gold, the sophistication of methods used to prospect for hardrock gold vary with the financial resources of the prospector. Drilling is often used to explore the subsurface. Surface geophysical methods may be used to locate geophysical anomalies associated with gold deposits. Samples of rocks or soil may be collected for geochemical laboratory assay, to determine metal content or detect geochemical anomalies. Hardrock gold particles may be too small to see, even with a microscope.
A recent study by Australian scientists found that termites have been found to excrete trace deposits of gold. According to the CSIRO, the termites burrow beneath eroded subterranean material which typically masks human attempts to find gold, and ingest and bring the new deposits to the surface. They believe that studying termite nests may lead to less invasive methods of finding gold deposits.
