In general terms it may be said that the abundance of the ores rather than their richness characterises the mines of Mexico and is the source of their wealth. Those which have most steadily produced bullion generally consisted of a main lode containing enormous quantities of low-grade ore of about 60 ounces per ton; and typical of these are the mines of Guanajuato, Pachuca, Queretaro, Zacatecas, and others. The ores, however, are not always low-grade, for great _bonanzas_ of exceedingly rich ore were encountered, making rapid fortunes for their discoverers.
