Second case: the study of indications and search of indications concerning abnormalities

The study of indications has as an objective to analyze the interest of a discovery to decide the possibility of going on to more detailed prospection phases such as: geochemical tactic, ground geophysics, ditches, wells, and sometimes drillings as well. The search of indicators of abnormalities consists in finding the mineral in situ, parting from geochemical or geophysical abnormalities or of alluvial indicators. In this stage of the search generally the chosen zone where substances that are being searched are known of and can be found in greater amounts. In most cases, it has to do with defining the mineralization extension parting from one or more punctual indicators. The value of this mineralization will be played out in relation to its recognized dimensions or supposed dimension and of its tenors. The job will mainly be done with:

• A compilation of a geological map if the outcrops are sufficient enough or of a map of the outcrops that will be the prospecting guide.
• The realization of a careful sample in order for them to be as complete as possible.
• The work will then develop carrying out the described following points.
