This is one of the oldest enterprises in the Russian geological exploration sector, famous for making three major discoveries of primary diamond deposits — the Mir, Udachnaya and Sytykan pipes. The resource base of the domestic diamond industry was to a big extent created due to the efforts of the Amakinskaya Expedition.
In the taiga, odd stone shapes can be found.
The rivers of Yakutia have always been the main transport routes for geologists.

The Amakinskaya, originally Tungusskaya, Exploration Expedition was established for the purpose of diamond exploration in Eastern Siberia on January 15, 1947 by order No. 32 of the head of Eastern Siberia Geological Department.
Today it employs almost 1000 people, including 175 geological and geophysical staff.
The Aikhal exploration party, based in Aikhal, consists of 13 drilling crews, and conducts diamond prospecting and exploration in the Daldyn-Alakit and Muno-Tyungsk diamondiferous areas.
The Udachny exploration party, based in Polarny, conducts drilling operations in the Daldyn-Alakit diamondiferous area. The Northern exploration party conducts in-hole geophysical surveys, and the Surface Geophysics crew conducts EM and gravity surveys in the regions of the Yakut Diamond Province, as well.
The expedition also includes a number of specialised research parties. One of them, the Aero-Geophysics Party is engaged in airborne geophysical surveying in scales of 1:25,000 and 1:10,000 within the entire territory of the Yakut Diamond Province, and in the Russian North-West — in the Arkhangelsk Region and Karelia.
The discovery, exploration and detailed study of diamondiferous kimberlite pipes and alluvial deposits has allowed the Amakinskaya Expedition team to become a pioneer in creating and developing new areas of geoscientific research — particularly, specific features of kimberlitic occurrences, the internal structure of diamond pipes, the nature of diamond content and the material composition of the Earth’s crust and upper mantle.
