History

The Vilyuy River basin was believed to contain mineral deposits at least as early as the 19th century, with Richard Maack reporting after an expedition to the area that the area was rich in iron, salt deposits, and precious stones. He described a nest of blue clay in the area between the Vilyuy and Malaya Bituobiya Rivers, but as kimberlites had not yet been discovered there was no official attention.

Around the beginning on the 20th century, a number of scientists and geologists noted similarities between parts of the Central Siberian Plateau and areas in South Africa, where exploitation of primary diamond deposits had already begun. In 1937, the Soviet government began to greatly increase effort to produce diamonds on its own territory, due in part to some other diamond-producing nations being unwilling to sell to the USSR. Expeditions were organized in the basins of the Yenisei River and in the Ural Mountains. The Ural expedition proved the more successful, finding small, but commercially viable deposits.

An additional government decree signed by Stalin in 1946 announced further exploration for diamonds, with expeditions mounted from Irkutsk into the region of the Yenisei River. The first officially recorded discovery of diamonds in Yakutia (the present-day Sakha Republic) was made in 1949 on an expedition along the Vilyuy. Initially, discoveries centered on placer deposits, which did not uncover the enormous primary deposits in the form of kimberlite pipes.

The first kimberlite deposit, Zarnitsa mine, was discovered on August 21, 1954. Further exploration in 1955 found over fifteen primary deposits, including the largest pipes at Udachny and Mirny. Over two hundred kimberlite pipes have since been identified in the Sakha Republic.

Mirninsky District was established on January 12, 1965, after large-scale diamond mining was started in the area and associated industries began to grow.

Administrative and municipal status

Within the framework of administrative divisions, Mirninsky District is one of the thirty-four in the republic.
