Add them all up and you get 2+ grams per ton. Doesn't seem like much, but all they have to do is shovel the pre-processed ore into a hopper to crush and further process to get the gold out. Even at 70% yield you get 1.4 g/t, assume 50% costs (high) and they end up with .7 g/t in product. They conservatively estimated the size of the stockpile at 25K cubic yards, so using a conservative estimate of 2500 lbs per cubic yard yields about 20,000 ounces of gold. Well worth going after. I think there is a lot more gold in the stockpile than that, recovery methods 100 years ago were 50% at best.
