Ihave a graduate student exploring a mining and processing site in Mexico near the town of Mineral de Pozos. Apparently this site produced mercury at two separate periods in history, but we are struggling a bit with a lack of good documentation. Can anyone suggest some sources, in English and/or in Spanish? Of course, references about the Mexican industry would be most useful, but general sources would be helpful, as well. Thanks for your consideration, PEM Patrick E.
