RE:100 million tons of ressource.....Yes , the Walker's don't speculate , they KNOW they can prove way more than 100 million tons . But if you listen carefully , Trevor says that the 100 million tons he is talking about is only at surface to the open pit depth and just between the PAK and SPARK . There are hundreds of million more tons that are underground and along strike all the way to at least PENNOCK LAKE . 100 million tons is literally just scratching the surface .
