Abstract
The first results on the geological structure of the deep horizons of a diamond deposit – the Mir kimberlite pipe are presented. According to the results of exploration of deep horizons, new data on the geological structure of the deposit was obtained. The morphology of the pipe with depth has a definite tendency to increase the volume of the ore body in comparison with the results of previous explorations. The material composition of kimberlites and their productivity to a depth of more than 1,500 m vary slightly. In general, the results of the exploration allowed us to obtain a significant increase in the reserves of kimberlite ore and diamonds with a total volume of over 40 million carats.
