stands for BoreHole ElectroMagnetic. Here is a description of this technology:
An edge based finite-element method has been applied to compute surface-to-borehole electromagnetic survey responses generated by a grounded-wire source for a 3-D model of the earth. The algorithm is successfully verified by comparison with other numerical solutions. Results show that a surface-to-borehole survey is efficient in understanding the responses for deep-seated inhomogeneity. This modeling is capable of providing the optimal survey design for deeper targets and can be used as an engine for 3-D inversion.
So, with this, they should be able to map out were the nickel sulfides are from surface down to 1000M in the area of Eagle 1. With the assays back soon and this survey, we may very quickly have a very good idea of what we have. I agree with K. the next few months will be very interesting!
