Absolute rubbish 1982.

Your statement shows that you have no idea about this type of Geological structure and the necessity of accurate data.

This is Scientific and Engineering expertise at its most technical.

To follow the paths that you and some others on this post have espoused would have taken NWE on a path to failure and guaranteed the loss of your funds.
I suggest that you spend some time and energy in appreciating the technology that is being deployed here.
