Creating A Simple Mapping of Land Gold

       In any mining operation or exploration we need to do a mapping of the land in an area that we will do some exploration activity, where the mapping is very important in order to reduce risk and support the exploration plan. Because, basically, mapping activities affect the continuity of exploration. With this mapping, we can see the beginning of the geological conditions of the working area and can see the potential resource deposits of the mineral deposits in areas that will be held exploration activities. This mapping is usually done at the beginning of the exploration activities. The first step is usually done in a mapping can be done by doing an analysis through a photo presentation by air or by using a satellite, where the presence of the review through the air we can see the geographic structure and local conditions and our land that will be held survey field.

     Once we know the initial description in detail the condition of the area and map the locations which we will survey the next step we can do a review directly into the area we have mapped through aerial photographs. At this stage of the survey carried out directly on the areas that we think have potential for economic mineral deposits. In making the gold potential map analysis of several factors required the presence of a mineral content of gold in an area such as the existence of hydrothermal water content which is a MINERALS GOLD FORMING PROCESS, sulfide minerals in the rocks, igneous rocks in the zone, and some cracks are present in the region. In addition, outcrops of rock outcrops that need to also note is the change or boundary stones, The Orientation Of Sedimentary Rock Layers, the orientation of faults and other signs. An important point should be plotted on a map base with the aid of equipment such as geological compass, inclinometer, altimeter, and natural signs such as the hills, valleys, river bends basin.

Specimens of Gold Ore Minerals

         Gold nuggets with large size of more than 2mm. And the Nuggets usually have a 20K or pure gold content of 83% to 92% or it could be up to 23K. And this nugget of gold usually has shades of orange yellow color. The formation of naturally occurring surface oxide layer that inhibits adhesion between the gold flakes. So when gold pieces collide with each other under pressure, they may be joined into larger sections. Another nugget may occur in the form of the original vein prior to erosion, often showing signs of abrasive polishing due to the flow. For many gold nuggets found in outcrop or in a deposit of placer gold veins or lodes that have been weathered. Gold nuggets are also many who find the prospect of the river area where the area has a metal mineral content is very high.

Weathering Process supergene gold

      Supergene gold deposits formed by natural oxidation or a weathering. The most widespread mineral association formed by natural processes that occur in natural ores. Important factor as the process of weathering is the presence of transport by water but also climate is very important because it controls the availability of water. The most intense weathering in tropical climates where warmth and plentiful rainfall combine to create ideal conditions. Where rainfall is short of the hydrological cycle contributes to the salt from sea water, especially chlorides, but including some sulphate dissolved in meteoric water. Short-term hydrology will contribute more salt from the sea rather than created as a vapor. microscopic flakes of salt from sea water bubble explosion carried out remotely by onshore winds and eventually reach the soil surface. This mechanism is effective in short hydrological time in which humans are contributing to salt, nitrite and nitrate of alkali and alkaline soil.

Eluvial Gold Deposit Types

       The process of removal of material from the horizon is called eluviation geology or soil or leaching. There is a difference in the use of this term in geology and soil science. In soil science, eluviation is the transportation of soil from the top layer of soil to the lower level with rainfall down the water in the soil horizon, and the accumulation of material at a lower level is called illuviation.

       Eluvial gold placed by the process of gravity on the surface of the hill, up and flat-lying areas. Particles of minerals or ore-forming mineral deposit type is deposited on top of a rocky hillside source. In some areas found in eluvial placer with ingredients that create economic value accumulated in the pockets of bedrock surface. Rainfall helps to bring the material surface, or floating, downslope. Eluvial deposits consist of fragments of rock and soil which are not consolidated lying on the surface. It is derived from coral quartz and other minerals deposits (supergene, reef quartz and layer) located at the top. Transported material contain gold deposits also form on the surface of the slope of the hill where the concentrated on changes in gradients, like, bottom of the hill. Deposits are usually located near the eluvial placer, which is an irregular surface on the hillside below the mineral resource.
       The location consists of a mixture of rock, gravel and debris that has been weathered and destroyed the nearby hill is the place easy to find gold. Gold is found in locations like this are usually rough and very concentrated on the bedrock. Eluvial containing gold and scheelite material highly enriched in arsenic, antimony and tungsten features that can be used in geochemical candidate for this type of deposit.
      Gold in fine fraction of gravel and sand-free; in coarse fraction is mainly in sulfide minerals (pyrite, arsenopyrite, galena, sphalerite, stibnit, sulphosalts silver) and their oxidation products. Part of the silver in sulfide and alloy sulphosalts and part is with real gold. Average test some placer materials show the following: Sn 84 ppm, 15 ppm Hg, 9.44 ppm Ag and 0058 ppm Au. Approximately 550 million m3 of gravel are present in the fans.
     Gold forms crystal deposits in hard rock is generally known as veins. A layer is usually formed in areas where the rocks that contain veins have been altered in some way. Gold is found in layers that are bound with sulfide minerals and Telluride. Mineral gradually destroyed by natural wind or rain, leaving only the gold behind. gold may range from pieces of grain-size nuggets.


There may be some of the less know how panning eluvial gold ore found on the path of the river or the prospect area which contains metallic gold ore. By using equipment made ​​from plastic pots or metal we can do an analysis of eluvial gold ore. And we also need to separate magnetic metal with a gold metal content of iron ore. Before you use these pans equipment wash with soap to remove any residual oil from the sometimes still tied at the bottom of the pan.
Step in gold panning: 

Look for areas in the bend of the river that have a prospect of the gold mineral ore. Then fill the pot you use for gold panning with sand, soil and gravel that you think have gold content of ore minerals. 
To begin the next step place the pan on the bottom of the water and gently shake pan and rotate them. Then tilt the pan for some materials rough stone are in a position above the rough and then you throw rocks slowly by hand.

Now turn and shake the pan back gold from side to side and pull it backwards, while partially submerging under the water pan. While such set up a tidal wave This allows each particle of gold is not out of the pot but was trapped at the bottom of the pan.
Tilt the pot of gold with the tip away from you slightly under water. While your hands are still shaking while positions remain as they are side to side, sink, lift and out of the water and tilted back, allowing it to form a wave. Tip forward again, letting the waves travel ahead to take out of the pan. Next turn back the pan from side to side again so that the metal back on the bottom of the pan
Some of the previous steps should be repeated until the only remaining approximately one tablespoon of the remaining fine material. This action is necessary to gently wash the used amount of dirt remaining. Eventually will be seen a few grains of fine gold ore at the bottom of the pan but still there are some impurities. To eliminate some black dirt that is most likely iron ore sand, we can use a magnetic metal to take it. Place a magnetic metal in a plastic bag so that the black sand collected on the outside of the magnetic metal for iron ore can be easily retrieved from a magnetic metal.

To eliminate some black dirt that is most likely iron ore sand, we can use a magnetic metal to take it. Place a magnetic metal in a plastic bag for iron ore can be easily retrieved from a magnetic metal. then enter a magnetic metal into a pot which contained gold ore, then iron ore will stick to the magnetic metal, while gold ore will be fixed and does not stick
Gold spots can then be collected with wet fingers and placed in sample bottles filled with water. A teaspoon is useful to collect the gold when present in large numbers
