This book contains over 50 stories of Lost Mines and Treasurers, all in the State of Arizona, plus a special section on the “Pancho Villa’s Lost Lootâ€. I found the data for this book while doing research on old mines for my series of books Mines of the American West. The “lost mines†were identified from articles in early American newspapers, and where possible I have tried to tie them to modern mines or areas. In doing this, some of them seemed to “fall short†in the area of fact and logic. The reader should understand that this is a collection of data from old and new publications and not a focused effort to find the properties. If the reader can glean critical information from these original articles that allows him or her to locate a “lost mine†or “lost treasureâ€, I leave it to them to reap the rewards.
