LOS CASTILLEJOS MINING AREA. PROSPECTS FOR GOLD AND SILVER GOSSANS COTO MINERO LOS CASTILLEJOS. PERSPECTIVAS DE GOSSANS PARA ORO Y PLATA Pérez Aragón , Ramón Omar López Kramer , Jesús Manuel Gallardo Eupierre , Emiliano coto minero gossan oro plata investigación mining preserve gossan gold silver investigation The Los Castillejos mining district is located near Fomento, Sancti Spíritus province, in the Los Pasos Formation, which features VMS Bimodal-Maphic deposits with sulphide copper+sphalerite ores and Au-Ag contents. These deposits, although exploited, were not evaluated as gossans for Au-Ag, being recently classified as virgin gossans due to their low degree of study for gold and silver. The paper systematises and argues several historical facts associated with these processes, contributing new elements with possibilities for the integral exploitation of the deposit with the extraction of gold and silver, and suggesting the need for geological research in the region. The analysis carried out is a first approach to relevant aspects that need to be studied. The need to reinterpret the information in the light of the advances in gossan studies and the increase in the knowledge of geological activity, makes it necessary to direct the projection of prospecting towards the identified virgin gossans, including the technical criteria obtained from the work currently being carried out. New elements are provided that argue for the inclusion of primary ores and also of the gossan, constituting a contribution to scientific knowledge for future prospecting work, an objective whose evaluation must be complemented. This research has a relevant current importance, because the price of copper and gold in the international market has a vertiginous and sustained rise and it is expected that there will be a great demand at world level in the next years.
