Don't forget there are different "dirts" in Scull Valley - two are the tailings and the "dirt" which is claimed to have the value.
The tailings never seem to be discussed The tailings are by definition dirt, but that don't mean that they can't be mined profitably at today's mineral prices.
We have the situation where things that were worthless in the 90's, could be profitable today.
..that said, there are real sites all over the place and no one REALLY knows what PMs are in the other runoffs......No ONE REALLY knows for fact whats in the ground in San Bernardino or perhaps what Realestate value they hold down the road. 20 turns to 10...LOL
