When all is set to acquire gold mine, there's a lot one needs to validate, whether there is gold in the mine before the acquisition, you need to know too whether there is enough gold, type of ownership, the title of the land, the carat of the gold, and quantity of gold you will be able to mine from the gold mine relative to the cost of labor or overhead to mine the from the gold Mine all of these requires step by step validation.
Let's discuss the local miner approach before delving into the mechanized Alluvial gold mining test, in any case, we will discuss the local miner approach that also includes modern testing results, to arrive at a conclusive alluvial gold testing method.
Most local miners, lookout for signs that give them lead that they have gold in their farms, signs like the composition of the soil, whether the contains iron that's mostly reddish soil, if the cocoa planted yield are generally poor, its leaves are yellowish, underneath soil composition consist of clay, also whether to farm is bounded by a stream on one side and or both sides. Also another sign they look out for is the kind of gravels found in the land or inside the stream or river by the mine is a good lead for the locals. The gavels found if they are reddish in color or white are good signs for them, if the gravels are mostly reddish mixed with white colors, there very good prospect that the land will have rich deposits of gold. These signs appear vague but they certainly enable the locals to know firsthand whether their farms have gold or not and more often than not it turns out positive for them.
Intuitively, and from experience, local Alluvial gold miners know that gold deposits are in a straight line, all they need to do is to dig along the characteristic line formed by the deposits and follow through to the end. This becomes the basis for an experienced miner both local and Mechanized to arrive at a literal graph diagram consisting of three lines in the alluvial gold mine.
let me try to explain it in the sketch below:
Red Line
_________________________________________________
Greenline
_________________________________________________
Yellow Line
_________________________________________________
As you can see above, we have a red line, representing the hotline, the green line representing the average line, and finally, the yellow line representing the low line. These lines above are drawn by the miner intuitively as they have tested the GPT (grams {of gold} per ton) on each line, for example, the hotline is 4gpt, the average line is 2.5-2gpt and the low line is 1gpt.
If the overhead cost of mining the low line will result in no good profit the miner might decide not to mine the low line to save cost and duration of mining. In the subsequent articles that follow, we will discuss how the locals conduct the Alluvial gold mining test and how Mining Companies conduct Mechanized Alluvial gold mining test.
