You have a lot in your profession that spend their whole life looking for something in the ground that is at 1ppm, and they go balistic if it gets to 5 ppm. All of the interpretation of it , is done using models. In fact , i hope you use geophysics for your pit designs which is after all modelling based on very sparse geotech driling.
How many people do you have modelling your pits? do you believe them?
1 or 2 ?
yet you dont believe when 1000s are saying that a rise for 200 ppm to 300 to 400 to 500 ppm is a problem!
