Sunshine_Miner Posted December 25, 2016 Share Posted December 25, 2016 On 2/20/2014 at 6:25 PM, ShinyCy said: http://en.wikipedia.org/wiki/Tertiary Basically, tertiary is a time period. Turns out that for some reason or another that a bunch of placer gold hangs out in gravels made up of rock formed during the tertiary period in North America. The reason it has to do with that specific time frame of formation is it coincides with the laramide oregeny and all that gold rich rock was subducted, melted, and redeposited in vein structures of epithermal nature and in secondary enrichment zones in some cases via groundwater, theres also good gold in a different ore assemblage in the near pre-cambrian granites. Thats my first step before I ever touch any maps is dig up the USGS report outlining what formations the gold is known to occur in then connecting that with known geological events, it completely cuts out any guess work of where the gold is coming from, what rock type you find it in, given the age of the formation / resistance to weathering and annual climate of an area you can determine whether placering or lode will be the most efficient way to mine. I think a lot of people fail to make this connection and thats why they often are confused as to why the granites in AZ contain fantastic high grade veins and the Granite state has little but fly poop gold that which has zero to do with granite. 1 Quote Link to comment Share on other sites More sharing options...
Bugler Posted February 14, 2017 Share Posted February 14, 2017 Thank you all who have shared these resources! I have spent years doing my own searching both on land and in numerous books and bulletins. I have found my share of gold in the West but have many more prospects to understand. This forum has kept my blood surging thru the long winters of Montana. Again, thank you for all the posts. Bugler 1 Quote Link to comment Share on other sites More sharing options...
vnord Posted May 23, 2017 Share Posted May 23, 2017 (edited) Hi, I've been using these sites: http://chroniclingamerica.loc.gov/http://azmemory.azlibrary.gov/cdm/newspapershttps://www.coloradohistoricnewspapers.org/https://cdnc.ucr.edu/cgi-bin/cdnchttp://www.elephind.com/http://montananewspapers.org/http://nebnewspapers.unl.edu/http://206.194.194.211:2011/http://oregonnews.uoregon.edu/https://sites.google.com/site/onlinenewspapersite/Home/usahttps://texashistory.unt.edu/https://newspapers.lib.utah.edu/search FEE SITE:https://www.newspapers.com They are online historic newspapers. I've done about two years of research; and am giving away about years worth on my site: https://vernnord1.wixsite.com/mysite-1 I've even produced a list of the largest silver nuggets ever found and written about in historic newspapers. But my site has a page on gold and silver nuggets, and, by state and county, coarse gold and silver, mined in the old days. Wire gold, leaf gold, slabs of gold, wire silver, crystalline silver, jewelry ore, picture rock, bonanza ore, cubes of gold, wire gold and wire silver in one piece of ore... The only thing that comes close to my research, is a NM placer government work, and the Mining and Scientific press, but there's thousands of pages to go through, in that database. By far the most comprehensive lists. I can't vouch for any particular entry, it's the best I can do. My blog, at Wordpress, has a lot of clippings, and might be of interest "reports of coarse gold and silver". So, to recap, cheers, and I'm giving away lots of info.

Saul R W Posted April 8, 2018 Share Posted April 8, 2018 (edited) There doesn't appear to be a pdf version yet, but "Handbook for Prospectors and Operators of Small Mines" by Max Wilhelm von Bernewitz is a nice addition to any miner's library. I inherited my 1943 copy from an uncle. It appears to be readily available at the usual book and auction sites. Von Bernewitz also edited another book worth owning, "Prospector's Fieldbook and Guide" by Henry Osborn.

Swampstomper Al Posted October 31, 2018 Share Posted October 31, 2018 Here's a little something for the home boys.. I came upon this quite by accident one day a-while-n-a-half ago.. I mean, who actually opens something found during a Google search titled "report.pdf?" Welll, I do, evidentally.. My reward?: BULLETIN 782 ORE DEPOSITS OF THE JEROME AND BRADSHAW MOUNTAINS QUADRANGLES, ARIZONA BY WALDEMAR LINDGREN DOI 1926 https://pubs.usgs.gov/bul/0782/report.pdf A few pages later I find a title "plate-2.pdf.." Had to open it.. Turns out being: USGS BULLETIN 782 PLATE 2 GEOLOGIC MAP OF THE BRADSHAW MOUNTAINS QUADRANGLE, ARIZONA 1926 (but actually taken from the survey done in 1900 - 01..) https://pubs.usgs.gov/bul/0782/plate-2.pdf Lossa lossa info. above -- 223 pages worth.. And you'll be happy to know additional copies may be procured from the Superintendent of Documents, Government Printing Office, Washington, D.C. at 50 cents per copy..

GotAU? Posted February 9, 2020 Share Posted February 9, 2020 Sorry I didn’t see this forum before I posted about references in a different one, but I used this geology dictionary in a class and find it useful for reading materials about mining and prospecting as well: Quote Link to comment Share on other sites More sharing options...
