I CAN TELL YOU ONE THING ABOUT THESE MINES THAT BY THE MASSIVE SIZE OF THESE DUMPS THEY MUST HAVE HUGE NUMBER OF LEVELS AND MILES OF UNDERGROUND WORKINGS DAVID ADAM GRENIS CURRENTLY IN HOUSTON TEXAS BUT I'M FROM BOULDER COLORADO.
Absolutely, the size of those tailings piles definitely indicates extensive underground workings! It’s fascinating to think about all the history beneath our feet. Thanks for sharing your thoughts, David! Hope you’re enjoying Houston, but Colorado is hard to beat! :)
