The Cullinan Diamond Mine - Yesterday, Today, and Tomorrow

History and Development

The Premier Diamond Mining Company was established by Thomas Cullinan (later Sir Thomas) in 1902, close to the finish of the second Boer War (South African War 1899 - 1902). The land was initially some portion of the Cornelis Minnaar Farm and was bought for an aggregate of £52,000 by Thomas. The organization was first enlisted on the sixth November 1902 as the Premier Syndicate however was later re-enrolled as the Premier Transvaal Diamond Mining Company Ltd. on first December, 1902.

Cullinan Village was built up in 1903 to give lodging and administrations to mine representatives and is found around 40 kilometers east of the South African capital of Pretoria in the Gauteng Province.

A standout amongst the most remarkable and acclaimed precious stone disclosures happened at the Premier Diamond Mining Company on 26th January, 1905 when a youthful mineworker named Thomas Evan Powell brought a substantial 3106.75ct harsh jewel quality jewel to his surface director Frederick Wells. The jewel is the biggest pearl quality precious stone at any point found and is broadly known as the Cullinan Diamond.

In 1910 Thomas Cullinan was knighted in acknowledgment of his commitment to the precious stone industry and in 1917 De Beers Consolidated Mines procured a controlling enthusiasm for the mine however later sold it to a consortium in 2008. Today, Petra Diamonds is the specialized administrator of the mine in the interest of the business consortium (PDCC - Petra Diamonds Cullinan Consortium) as they have 74% enthusiasm for the organization.

In 2003 the mine was renamed The Cullinan Diamond Mine to commend a long time since its underlying opening.

Cutting edge Mining Techniques

The Cullinan Kimberlite pipe is arranged on the stable Kaapvaal Craton which is assessed to be roughly 3 billion years of age. It is the world's second biggest jewel asset of 181.4 million carats (add up to asset base of 203.3 million carats). The pipe itself looks like a carrot shape and extends 32 hectares at the surface (around 30 soccer pitches) and extends 1,073 meters profound.

From 1902 to its constrained conclusion in 1932 because of the financial discourage, the mine worked as an open-pit with a profundity of 189 meters. At the point when the mine re-opened again in 1946 it began generation under different mining strategies. The mid 1970's used buckle mining with the mid 1980's performing sub-level open stoping. Today, the mine is at a profundity of 747 meters and is utilizing automated trackless square give in mining as their fundamental strategy for jewel mineral extraction.

Cullinan Diamond History and Notable Discoveries

In 1905, the mine broadly revealed the 3106.75ct harsh Cullinan Diamond. The unpleasant precious stone measured 10 cm long by 6 cm high and 5 cm thick and tipped the scales at 621.2 grams. The harsh precious stone was sold to the Transvaal government for £150,000.00 who then talented it to King Edward VII on his 66th birthday celebration on November ninth, 1907. It has since been part and cut into 9 noteworthy stones and 96 littler stones. These 9 noteworthy precious stones and their general history are point by point beneath.
