Flat-Fault Gold in Sonora, Mexico
July 2004 by Edgar B. Heylmun, PhDMexico is not noted for gold, but is better known for silver and copper. However, the states of Chihuahua and Sonora, in northwestern Mexico, contain some sizeable gold deposits. A number of these deposits were mined during the boom of 1982-2002. One operation that has remained active up to the present is La Herradura Mine...
These are just some of the ways I have been able to find new spots to metal detect for gold.
Like any good prospector, I sampled the bedrock—and am glad I did. I found a half a dozen pieces in the first pan, so I took a second pan. The results were the same.

I have found gold more than 200 feet above the river. It was not unusual for nuggets of an ounce or more to be found in these deposits, but fine gold and flakes are much more common.
You can learn a lot from a small mining operation because you have to become proficient in every job. Soon I was preparing fuses, placing powder (dynamite) and learning the ins and outs of drilling and blasting.
