Ann: Kimberlite Drilling Targets Defined at High Priority L259, page-29

The most interesting thing to me is that L259 displayed a gravity low compared to L251 which displayed a gravity high. This supports my theory that the low magnetic, less dense L259 is an older deeply weathered kimberlite which is more likely to be more diamondiferous compared to the younger high magnetic, higher density and less weathered kimberlites such as L251. Mineral Services (lab consultants) have the view that the older kimberlites "sampled more substantial amounts of diamondiferous mantle and hence may contain greater quantities of diamond" (21 December 2015 announcement). Note that it was the older kimberlites like L259 that eroded and contributed to the diamond-rich Calonda formations, not the younger ones which are more preserved. The results also suggest that the L259 kimberlite is softer which improves suitability for bulk processing at the DMS plant.
