Anybody ever crush listwanite for gold? There is a listwanite-nickel-gold deposit near where I live. I have found listwanite in several locations in the same county. Mostly what I am wondering is if the gold in listwanite can occur as free milling. Hand crushing rock takes elbow grease and I am trying to determine if it is worth the effort. Any knowledge about listwanite and gold would be much appreciated.
