                         company Xstrata Copper, are located in the region of Cusco, Peru, 
                         at the Espinar province. The commodity explored by this company is 
                         the structural copper, extracted from the minerals chalcopyrite, 
                         chalcocite and bornite. The main aim of this study is to identify 
                         regions that hold a great concentration of copper, with the 
                         purpose of locating possible new areas of extraction as well as 
                         meaning to find regions with possible contaminations caused by the 
                         mining activity. The data utilized are multispectral images from 
                         the ASTER sensor, obtained in September 28, 2000, courtesy of 
                         Universit{\'e} Toulouse III - Paul Sabatier. The method used 
                         throughout this work was the band ratios. This method enabled the 
                         making of two final products: the image of the studied area 
                         classified by the spectral answer of the chalcopyrite and the 
                         image of the studied area classified by the spectral answer of the 
                         bornite. In order to make a correct reading of the final products, 
                         it was used as a mineralization pattern the spectral signature 
                         present in the area surrounded by the Tintaya mine. After the 
                         final analysis of the obtained products, it was observed that the 
                         image resulted from the spectral answer of the chalcopyrite shows 
                         with better precision the shape of the regions classified as 
                         similar to the area mineralized.",
