Tom, whose Spanish is nearly as poor as mine, says that by the end of the trip, he could shout "Donde esta mi muletas!" ("Where are my bags!") with the best of them. [He is third from the right in the back row, by the way]
Tom reports that, "The field trip went underground all three days they were there, including five hours in the largest producing silver mine in the world [note: in 2006, the Penoles' Proano (Fresnillo) mine produced 33.49 million oz Ag] What the picture doesn't show is the incredible heat and humidity near the working faces. In this mine they have intercepted five veins, the longest of which is 6.5 kilometers from east to west (typical precious metals ore shoots run less than one kilometer). As most of the district is under alluvial cover, and has never been explored with modern methods, it is entirely possible it could hold more than 10 percent of the entire world reserves of silver."
