Excellent post. The Minnie Moore Mine area was highly prolific and it would seem very unlikely that all of the high-content silver ore at or near the original site has been fully mined, especially in light of the fact that the original Minnie Moore vein ended abruptly at a geologic fault and was never re-located. This is further discussed in Victoria Mitchell's "The History of the Minnie Moore Mine", a very interesting read. http://www.idahogeology.org/products/reverselook.asp?switch=title&value=History_of_the_Minnie_Moore_Mine,_Blaine_County,_Idaho
