Hi xxxxxx,
Our research group, the Geophysical Inversion Facility at the University of British Columbia, has been working with geophysical datasets (collected 1992-2004) from the Tli Kwi Cho area over the last 3 years. We've recently submitted 3 papers to SEG's Interpretation journal and are currently doing revisions after receiving the initial review. We expect publication in early spring 2017.
The goal of our research was to invert magnetic, gravity, gravity gradiometry, time-domain EM, frequency-domain EM, and airborne IP data in 3D over the two kimberlites and compare the recovered models to the known geology and drilling. While the inversion codes have the capability to incorporate different kinds of geologic information, we purposely kept the inversions simple to determine how far and well the geophysical data alone could get us. The results indicate that the combined data sets can differentiate between different kimberlitic rocks and our recovered models are very similar to the geology model presented by Harder et al (2009).
We held a workshop in May 2015 to discuss our results with people from industry and discuss the deposits.
This page provides a bit more information on that and has our SEG and ASEG abstracts at the bottom.
If you are interested in the 3 full papers, I can let you know when they have been approved for publication and likely send you a copy of the approved manuscripts.
Cheers,
Sarah
