In many countries mining legislation allows individuals to take claims for extracting minerals. However, the question arises: how not to make a mistake in choosing the territory?
Geochemical survey
If you want to take a site for exploration and mining, we can conduct our own research on it, which in a short time will reveal its potential. Studies are carried out by sampling soils by a regular network and determining the contents of the desired elements or minerals using an portable XRF spectrometer.
In small areas, in order to determine the best location for the trench or borehole, it is usually carried out at a scale of 1: 10,000 (sampling points after 10 m, distance between profiles is 100 m). If we are talking about large areas, estimated at several square kilometers or tens of square kilometers, then it is advisable to initially make a small-scale survey of 1: 50,000 or 1: 25,000 (testing network 50x500 or 25х250). After that, on the identified anomalies, it makes sense to repeat the survey on a dense network.
It is possible to determine 26 elements simultaniously.Limits of detections of portable XRF analyzer

The scale of survey is 1 : 50,000
Gold and platinum group metals are not detectable by portable analyzer in concentrations in which they are present in the soil. Anomalies of these elements can be judged indirectly by the anomalies of satellite elements, which are also called indicator elements. Gold grade can also be determined by a special gold spectral method. This method, although less accurate than traditional fire assaying, has a higher resolution and lower cost.
As a result, you will get a map of distribution of elements with delineated anomalious zones. If you want to sell your claims, the survey can significally increase both their cost and attractiveness for potential investor.
