(Mina Milpillas, Cuitaca, Mun. de Cananea, Sonora, Mexico)

New find of azurite and malachite from this mine (2007).

The Milpillas mine lies within the Municipio de Cananea, 17 km north (by road) of the village of Cuitaca. When azurite specimens first came to Tucson, they were reportedly occurring near Nacozari. Later investigation and visitation revealed the actual location to be northwest of Cananea, which itself is northwest of Nacozari (Marcus J. Origlieri info).
