Hi .. Psi

With your experience, just curious for the following:

Firstly, did MOU run a geo survey ~ ground magnetics, etc, and are the results confirming under-ground drilling results (I couldn't locate this info)?

Secondly, and more to the point, why would one run this type of analysis
- what does it prove?
- how does it operate (saw a google photo of a large mobile apparatus)?
- how would it differentiate the ground mix, specifically - coal?
- can it accurately determine the coal bearing area (assume can't determine coal type?)?
- finally, can it go to great depths, or is it limited?

Cheers :)
