(Mina Ojuela, Mapimí, Mun. de Mapimí, Durango, Mexico)
Workings included the Cumbres stope; Esperanza stope; Ojuela stope (15th level); San Diego stope; San Judas stope (13-14th levels); San Pointe stope (14th level); Santo Domingo stope (5th level); and the Socavon shaft.
Mine includes the Americanna, Americados, Norte & Ojuela entrances.
IMPORTANT NOTE: Many minerals sold as coming from the Ojuela mine are in fact from other Mexican localities such as mimetites (Velardena or Santa Eulalia), smithsonites (Santa Eulalia), pyromorphites (San José mine near Guazapares or Zimapan, Hidalgo), "endlichites" (Sierra de los Lamentos) etc. etc. (Moore, 2008).
NOTE on the mineral list: The colour of the pink to violet adamite is caused by a small Mn content, NOT by a cobalt content (see http://www.mindat.org/mesg-6-92888.html).
