- EDS Confirmed
Brilliant, granular crystals of Tellurobismutite with minor Tetradymite. This specimen is out of the old Dan Erling stock, a mineral dealer out of Millwaukie, Wisconsin. The specimens that I have were originally labeled at Tetradymite. In 2008, I had some analyzed with EDS, which identified the Tellurobismutite. Tetradymite was also detected as well as trace Chalcopyrite and Xenotime. Visually alot of it appears to be Hessite, but there is considerable Bismuth (50-52%).

Mercury has not been mined in the USA since 1992 when the McDermitt mine in Nevada closed. It is now only produced as a by-product from gold-silver mines. Nonetheless, the USA is the leading exporter of mercury since it is still produced through secondary recovery programs and recycling. A 76 pound mercury "flask" averaged $550-650 in 2008 (USGS). At one time the USA had many mines namely in California. Terlingua, Texas had producing mercury mines. Terlinguaite, like this specimen, was a chief ore at Terlingua. This is an old Carleton Davis specimen with tag.
