The main area of operations of the Expedition was the Malaya-Botuobia diamondiferous area, included in the area of oprations of the Mirny Mining and Processing Division. Over time, the volumes of exploration increased as did the area of operations of the Botuobinskaya exploration expedition.
After Yakutsgeologia Production and Geological Association was liquidated, and the State Committee for Mineral Resources of the Republic of Sakha (Yakutia) was created, the Botuobinskaya, Amakinskaya and Chernyshevskaya Exploration Expeditions on a voluntary basis amalgamated with PNO Yakutalmaz with the approval of the Council of Ministers of the Republic of Sakha (Yakutia). In this way, the expeditions were able to maintain their volumes of exploration and retain their highly skilled staffs.
