In Search of Diamonds

June 15, 2014

The Mirny diamond mine (aka Mirna, Mir, or “Peace”) is one of the oldest diamond mine in Russia, located in Mirna City, just below the Arctic circle in the Sakha Republic of Eastern Siberia in northeastern Russia. The Mirna mine is built over the Malaya Botuobiya kimberlite field. The mine is located in permafrost which extends to a depth of 1600 feet, and temperatures inside the Mirna mine range from -50F to -70F.

The Mirna Diamond Mine is the deepest open pit diamond mine in the world, and one of the deepest open pit ore mines in the world, at nearly 2,000 feet. At that depth, it takes approximately 1 1/2 to 2 hours for an ore truck to drive from the bottom of the mine to the upper rim. The first discovery of kimberlite in the Sakha region occurred in 1954, and the Mir kimberlite field was discovered in 1955. Opened in 1957, the Mirna mine has ceased operation since its exhaustion. While in operation the mine had an averaged yield of 2 million carats annually.
