Model of Recently Discovered Kimberlite Pipe at
Botswana Diamonds is pleased to present a three-dimensional model of the newly discovered kimberlite pipe on
A high-resolution ground gravity survey conducted during
Data from the RC holes was reconciled with the ground gravity data to construct a three-dimensional model of the kimberlite pipe. The best fit model showed an East - West trending body gently dipping to the east with a surface expression of 80 x 40m. The results are displayed in Exhibit 1 and more fully described in the glossary:
Exhibit 1. First Pass Model of Thorny River Kimberlite
http://www.rns-pdf.londonstockexchange.com/rns/7643I_1-2020-12-15.pdf
This work is significant in providing a maiden three-dimensional model for the kimberlite within the
The next step comprises drilling core holes to further confine the geological boundaries and microdiamond sampling to determine a first pass diamond grade estimate of the body. Petrographic studies will be used to confirm the kimberlite types. Geological modelling is an ongoing and iterative process with every piece of new work enhancing and increasing confidence in the model.
Precision work on the gravity data also discovered an additional anomaly to the east, which could be an extension of the kimberlite pipe and will be drilled in the New Year.

Glossary
The exhibit shows the intersection of a number of boreholes with the three-dimensional model of the 'bagpipe' shaped kimberlite pipe. The different colours within each borehole represents different rock types, for example, lime green is kimberlite, olive green is kimberlite breccia and mauve and red are different granite varieties.
