se). The exploration specialists have found data from remote sensing are a very useful tool to discover mineral 
IM deposits. Most of the previously obtained data came from either field observations or photointerpretations. 
ies. This project shows teledetection technique capacity which helps the exploration process. The study field 
atic includes the Cerro Blanco Mining District, located at Sierra de La Huerta. It is well known by its old mining 
activity in polimetal exploration. With qualified and enough information from field work which supports 
teledetection and that can load to new areas of interest. Digital image processing like: enhancement, 
classification and filtering techniques were used. These showed different surface characteristics of the area 
namely, some anomalies detected in the mentioned mining district. It is important to remark that this 
methodology will only be valid once the association between the visual interpretation results and the field 
thematic information is carried out.
