Mirna Diamond Mine - Russia - No longer Operational
Natural diamond sources have been discovered in approximately 35 different countries around the World across several continents. Diamonds, and consequently mines like the Mirna Diamond Mine in Russia, are found in areas where there have been volcanic activity or erosion and where natural elements such as streams, rivers and even glaciers might have taken them. When such sources are discovered mines, such as the Mirna Diamond Mine, often follow. The Mirna Diamond Mine has ceased operation since its supply of diamonds was exhausted. While in operation the mine yielded 2 million carats every year. The Mirna mine is now famous as the world's largest man-made hole.

Information about Diamond Deposits
Diamonds reach the surface of the earth via volcanic pipes or via placer / alluvial deposits. The purpose of the mines is the extraction of valuable diamonds from the earth. The mines are plant operations built to extract diamond crystal from either underground or from the surface. When diamonds are extracted underground, the mine needs a system of excavations in the rock to gain access to the kimberlite rock. There are a limited number of commercially viable diamond mines currently operating in the world which use tunnelling and excavation methods. However, diamonds are also mined using the Placer or Alluvial mining methods when host rock is washed away by streams and rivers and diamonds are deposited as sediment in the stream sands in 'placer deposits' which also called Alluvial deposits.
