Very interesting.  Another little tidbit not in that article.  There
was a radio quartz mine only a few miles from my home in Tellico
Plains, TN.  A photo of what's left is here, bottom of the page:

The vertical shaft has been filled in but the horz part remains. There
is some beautiful quartz on the walls.  I've never bothered to try to
learn any of the history of this mine.  Mostly what is know is that it
was an excellent place to take yer girlfriend from some private time
:-)
