For people that are confused by readings of concentration.
1g/ton means 1 gram of gold for every ton of dirt on average in that sample area. The meters have absolutely nothing to due with concentration. The only thing meters tell you is at what depth the sample was taken.
So people mulitplying the meters by the concentration, and doing all sorts of other idiodic calculations need to go back to grade school.( Seen this on stock house by some id*ot named gone_fishing)
It's not rocket science.
