gollum Posted April 13, 2015 Share Posted April 13, 2015 You can also use this (my absolute favorite) USGS Circular #1178: 1998 Assessment of Undiscovered Deposits of Gold, Silver, Copper, Lead, and Zinc in the United States Download the 180MB FULL REPORT It explains most of what you want to know about the different geologies in the United States that hosts the five biggest paying minerals (Gold, Silver, Copper, Lead, and Zinc). It has maps and goes into as much detail as you could want. Mike 5 Link to comment Share on other sites More sharing options...
