[QUOTE="Parks, post: 214523, member: 6315"] You might be thinking of the ore body of the deep lead. The ore body contains the gold at a level in a deep lead. If you have to go over 100ft down to reach the ore then it's a deep lead. I think the cut off is at 40 ft. Above 40 ft is considered shallow workings. Below 40ft became a mine. Like out near Smeaton you get a series of mines along a deep lead. Deep leads don't have to be underground. When they are pushed up by volcanics they are still deap leads, and then called placer deposits. So on the side of a mountain you may find the remains of an ancient river bed that is a placer deposit. If the river contains gold below 100 ft then it's a deep lead. If not it's a placer deposit [/QUOTE]
