(Mina Armonía)

Old abandoned Cu mine: one of the most important in the district. Some Co and Uranium mineralization were found during the heydays of the mine.
According to Alan H. Clark, the "cobalt rich minerals were emplaced as narrow (1-12 mm) veins in altered diorite country rock, and are now preserved largely as fragments in late stage calcite-ankerite vein material".

Alan H. Clark also stated the presence of Jordisite. According to him: "the Jordisite and less problably molybdenite, may have formed under superegene conditions".
