Yes. Some of the gold grade left behind by the old timers was 10g/t plus and that was nothing compared to the 1 oz p/t head grade they were mining in before the water problem hit in the early 1900's.
As you know, these styles of deposits tend to be many times deeper than their strike and we already have km's of known strike. You probably read about that recent mega high grade discovery out near Kal where they pulled 23,000 oz's of super grade out of a space the size of a room. The area still has miles of gold left imo. Coming together. dyor.
