X-ray of soil content is called a radiometric survey. It is nearly always flown at the same time as the airborne magnetic survey. It only tells you about the top 2cm of till/soil. This is not much use when the kimberlite is covered by 5-20m of till and glaciers have "smeared" the "soil" around like a childs finger painting. Looks like a mess.
You may mean X-ray fluoresence. Again only in the top few cm and it is currently a handheld unit. It can however classify minerals.
You may mean Hyperspectral scanning. This is the top 1cm and can classify minerals. Needs a lot of sun and no snow. Therefore is not much use on Baffin (though they should try it IMO).
Geophysics is the future. Nearly all the outcropping easy mines have been found. Elephant country is rare. The future is deeper. And deeper is geophysics and new mineral chemistry techniques in development.
Drones will not be flying until 2016 when the civil aviation authority will introduce new laws and regulations. Currently it is nigh on impossible to get a license for on land UAVs beyond line of sight. You need darn big UAVs to hold geophysical equipment. It is heavy.

You said "then use other diamond mines as the reference to derive the depths of the pipe." This sounds like you are describing the experience of the geologist. There is really no way to esimate the depth of a kimberlite other than modelling geophysical data (EM, gravitty or mag usually). In any case, when we have a kimberlite target we just drill till we hit basement rock anyway, so depth is not that important.
I have no idea what you mean by "one human drill".
