The article analyzes primary diamond deposits and their reserves from the viewpoint of economic efficiency and geology. A new principle has been developed for classifying the ALROSA diamond-bearing kimberlite deposits based on the analytical criterion expressed as the minimum mined rock amount per 1 USD of commercial output in 1 t of ore and an additional criterion expressed as the minimum efficiency of 1 USD of commercial output. Based on the offered criteria, all kimberlite deposits are divided into three groups:
- Group I—marketable diamond deposits (MDD)—over 80 USD in 1 t of ore, conventional efficiency factor is from 0.37 to 0.798 USD per 1 t of mined rock;
- Group II—medium marketable diamond deposits (MMDD)—from 40 to 80 USD in 1 t of ore, conventional efficiency factor is from 0.37 to 0.2 USD;
- Group III—poor marketable diamond deposits (PMDD)—under 40 USD in 1 t of ore; conventional efficiency factor is below 0.2 USD.
For open-pit diamond mines in Western Yakutia, the limit figure for minimum mined rock amount per 1 USD of commercial output per 1 t of ore is 0.15 t. The offered criteria allow the early allocation of a deposit in one of the listed above groups (MDD, MMDD, PMDD) for defining the strategy of mining and the level of georesource potential:
• MDD group—all-inclusive integrated development and use of the georesource potential of the deposit with the open-pit and underground mining technology;
• MMDD group—maximum possible development of the georesource potential (up to 70 %) by means of deep and ultra deep open-pit mining with undercutting;
• PMDD group—development of economically efficient part a deposit, with special schemes of accessing and prime accumulation of diamonds on pit walls, or using new modes of transport.

Ключевые слова Georesource potential, mineral and raw material base, mined rock coefficient, net profit per 1 USD of commercial output
