Use the search engine at the very top of the UNT page to search the library. The library has loads of various documents regarding “gold” including mining/milling, mineral deposits, tertiary channels, geology throughout the Western United States and Alaska.

For those of you interested in the California Southern Mother Lode check out the minerals industries surveys of the California Mother Lode including Calaveras County (part 1) and Tuolumne and Mariposa Counties (part 2) by Julihn & Horton 1938/1940:

      I have not even scratched the surface of this website link. All kinds of diverse articles and photos from all over the country. There are many photos of legends in the prospecting world. I tripped over this site years ago, forgot about it, and then found it again yesterday while doing research. Check it out at http://www.billandlindaprospecting.com/

      I know a lot of you are waiting for the new updated Land Matters Mining Claims Maps. That update should have been available on Monday but the BLM is having some technical difficulties with its Secure Transfer Server and we have been unable to update the active mining claims information on our maps.
      Our contact at the BLM says the problem has been identified and  should be corrected tonight.  We should be able to access the data in the morning.
      I know this is a critical map update for a lot of our users. I'll post here as soon as the maps are updated.

      Gold Prospecting with a VLF Metal Detector by Dave Johnson
      Chief Designer, First Texas Products & Fisher Research Labs
      March 2010 Edition
      This book explains how to use a VLF metal detector for finding gold. The author has nearly 30 years’ experience in the metal detector industry working for several different companies, and designed several of the most popular “gold machines” on the market. These include the Tesoro Lobo, White's GMT and MXT, and of course the Fisher Gold Bug and Gold Bug 2. Although the product emphasis is on the machines currently “Made in El Paso”, the features of competitors’ machines are also discussed. This booklet is useful no matter what brand of metal detector you use.

      I just finished reading "The Civil War Writings" by this man.  If you are a civil war relic hunter I think these personal memoirs of A. Bierce might have some excellent leads to locations. One his duties was battle field cartographer ...
      he does not glorify war at all
      Steve, not sure which forum you fit this too...if any.
