Unlike classic projects for the direct extraction of gold, silver and various metals from rock, the interest is based on the particularity of the “Aluvion Royo I” project, which consists of sediments generated by the natural action of morphological disintegration caused by atmospheric agents in the area; therefore, it refers to the classification of the metalliferous sediments contained in the sedimentary deposits of the valley floor.
The exploitation process was defined as strategic, as it allows the natural physical and magnetic concentration of minerals to be exploited, separating the particles according to their natural properties, using only physical methods.
