They won't run that material and if they decide to they should just close the doors because it would signal complete incompetence.
It would cost over 1.2 million to conventionally process that tailings pile (minimum). Even if gold was $1,500 and silver at $50 they would be hard pressed to make any profit at those grades.
MAYBE they could heap leach it for substantially less cost but don't think they'll attempt to go that route.
