The Horcon project is located in the Guanajuato mineralized region and is located approximately 45 km northwest of Guanajuato.
Approximately 25 km of veins are hosted by the same rocks as at Guanajuato and are along the regional trend of mineralization. In addition to the veins, polymetallic replacements and volcanogenic massive sulphide deposits are known in the area.
EXMIN focussed work on the Horcon mine, where underground workings from past mining have exposed several veins and indicates the potential for developing shallow Au-Ag-Pb-Zn resources.
