Conclusions:
- With (electrically) thin or no lake fill or overburden, can determine the geometry and gross internal structure of top 1/2-2/3 of the pipe
- With thick lake fill, can sense the presence of a kimberlite beneath till layer, but cannot obtain much geometry or property information
- After a single drill program, can re-perform the inversions holding constant the resistivities obtained from logging
- Any conducting structure that brings more current in will “illuminate” the body much more, e.g., Trillabelle
