The Botuobinskaya Expedition discovered the Botuobin Field in 1994 during drilling within the boundaries of the Viliuidko-Markhin deep fault zone. One of the bore holes revealed the kimberlite body, which served as the discovery of the Botuobinsk Pipe. The Botuobinsk Pipe is located 205 kilometers to the northwest from Nyurbin, 315 kilometers to the northeast of Mirny and lies at a depth of 78-110 meters under the strata of Mesozoic deposits.

In the same year, a land-based magnetic survey was conducted at a scale of 1:2000 (a 25õ25-meter grid) directly surrounding the pipe in an area of 1 square kilometer, as was a gravimetrical survey at a scale of 1:5 000 (a 50õ40-meter grid), and a 0.4-kilometer area was covered with a grid (100õ100 meters) of transient method points with a 100õ100-meter spread. But none of these methods identified the kimberlite pipe. All of the bore holes were subjected to extensive geophysical well logging, which provided insight into the magnetism, relative density and electrical conductivity and in a wide range of frequencies, radioactivity of kimberlites, enclosing rock and overburden. Most of the bore holes were subjected to a cross-well radio-frequency survey, which showed that the kimberlite body is distinctive because of its anomalous attenuation of radio fields.

Thereafter, a land-based magnetic survey was conducted at a scale of 1:5 000 in the immediate vicinity of the Botuobinsk Pipe on an area of 100 square kilometers with the purpose of finding new kimberlite bodies,  as was an aeromagnetic survey at a scale 1:10 000 at the intefluve area of the Khannya-Nakyn tributaries (800 square kilometers).

These surveys identified a number of promising magnetic anomalies of the pipe type, and in January 1996, the geologists of the Botuobin expedition, discovered the Nyurba diamondiferous kimberlite pipe upon verification of magnetic anomaly N-9.

The Botuobinsk Field, according to preliminary data, is a highly diamondiferous primary diamond deposit with considerable ore reserves. The average diamond concentration in the bore holes is more than 5.7 carats per tonne.

The Nadezhda prospecting shaft was tunneled into the Botuobinsk pipe and 30,000 tonnes of kimberlite ore were extracted from it.

OAO Alrosa-Nyurba is the holder of the license to use the subsurface resources of the Botuobinsk Pipe for the purpose of geological research and diamond extraction.
