If I had done work for cprk, and was worried at all, I would ask to back up to the concentrate pile, have them dump a couple of skidster buckets full in the truck. Then I'd be smiling the mill would be smiling everyones happy! When they want to have me bring it back, I drive back with my truck, they wright a check, I unload the concentrate! Smiles all the way around!! Now that would be a WINNER WINNER CHICKEN DINNER!!! FOLKS!! Or I just sit back and wait a few more days!! I'm looking forward to the pr's of when they are crapping out concentrate 24/7 and run out of rail cars to put it in!! YA BABY!!! I think I can almost see the promised land!!
