Actually, the area where this mine is located–Zacatecas, Spaniards start producing silver all the way back in 1540. When initial production at the Great Fresnillo Mine started in 1824, Mexico was producing 55% of the world’s silver production. The ore grades were much higher in those days.

For example, average yields for silver production in the United States and Australia in the late 1800’s was 40-50 oz per ton (oz/tonne).
