I havent allowed for specific gravity as well, SG of rock is about 2 on average so everything can be pretty much doubled. (SG of cobalt is about 8 I think from memory but that's immaterial)

So I've redone the numbers below taking a good hard look at those red spots and making a guess at the size of them, and a depth. . . allowed for SG. Here you go . . .
