Jean-Raymond Boulle is the founder of four publicly traded companies with deposits of nickel, cobalt, copper, zinc, titanium and diamonds.


Early career[edit]

Boulle worked for the De Beers Diamond Trading Company ("DTC") for ten years, in Zaire, Sierra Leone and Antwerp, Belgium, and then established Boulle Inc. in Dallas, Texas, US.[1]

In 1984 he began exploring for diamonds, first in Minnesota, then in Arkansas. In 1987 he formed Arkansas Diamond Development Co., to carry out exploration work on the Crater of Diamonds State Park in Arkansas.[2] He claimed there were $5 billion worth of diamonds there, but in 1996 it was halted as it was found to be not worth mining.[3]

Diamond Fields[edit]

Boulle was chairman, founder and CEO as well as a major shareholder of Diamond Fields (Diamond Fields Resources Inc. TSE:DFR)[4] which commenced trading on the Vancouver Stock Exchange on April 6, 1993 and, in late 1994, discovered nickel, copper and cobalt ore bodies at Voisey's Bay Mine in Labrador, Canada. The Voisey's Bay Mine deposit was estimated to contain 141 million tonnes at 1.6% nickel.[5] Boulle and Robert Friedland worked together in Diamond Fields and, in 1996, the Voisey's Bay Mine Project was purchased by Inco for CND$4.3 billion.[4][6] Boulle's next company, Diamond Fields International is involved in sea floor mining with interests in mining deposits around the world.[7][8][9]

American Mineral Fields[edit]

His Boulle Mining Group[10] is headquartered in Luxembourg and in 1995 founded American Mineral Fields (later renamed Adastra Minerals), listed on the London Stock Exchange’s Alternative Investment Market and the Toronto Stock Exchange. Adastra Minerals developed mining projects in the Democratic Republic of Congo and a joint venture with the government of the Democratic Republic of Congo to re-treat the Kolwezi tailings project. Adastra Minerals was purchased in August 2006 by First Quantum Minerals, a mining company then with dual listings on the Toronto Stock Exchange[11] and the London Stock Exchange (until 31 May 2016).[12] In 2001, Boulle Mining Group Luxembourg acquired the Sierra Rutile Project (a producer of natural rutile) and of the Sierra Minerals SML Bauxite Mine in Sierra Leone, West Africa which became part of Titanium Resources Group, taken public on the London Stock Exchange's Alternative Investment Market in August 2005.[13]

His mining group's subsidiary company, Greenland Gold Resources Ltd[14] is in Greenland exploring for nickel, copper, cobalt, platinum group elements, titanium and graphite.[15]

Other work[edit]

Boulle Mining Group Luxembourg was the largest shareholder in World Titanium Resources,[16] the Australian Securities Exchange listed[17] discoverers and owners of the Toliara Sands[18] titanium deposit in Madagascar. World Titanium Resources was delisted from ASX on 30 January 2017 and is now privately owned as World Titane Holdings Limited.[19][20]In December 2017, Base Resources signed a $75m agreement to acquire an 85% interest in the Toliara Sands project in Madagascar from World Titane Holdings Limited.[21][22]

Together with the Government of Mauritius, Boulle is one of the three controlling shareholders of Omnicane,[23] a publicly listed company on the Stock Exchange of Mauritius. Omnicane owns sugarcane plantations in Mauritius and produces refined sugar. Omnicane also generates around 30% of the island's electricity for the Grid and 40% of the country’s renewable bagasse-based energy.[24][25]

In December 2014, Boulle's company Tendyne Holdings Inc. announced the first successful human Mitral Valve implant at the Royal Brompton Hospital in London, England.[26].[27]


He has been accused of profiting from Africa's misery(1998) and manipulating African governments (2000),[28][3] with one of his companies, America Mineral Fields included in a draft of a UN report on the illegal exploitation of resources from the Democratic Republic of the Congo.[29][30] The United Nations Report S/2003/1027 sent by United Nations Secretary General Kofi A. Annan to the Security Council on 23 October 2003 later removed the names of several companies, including America Mineral Fields.[31][32]

Personal life[edit]

Boulle is a Mauritian citizen, and lives in Monaco.[33][34] In 2007, Boulle was made a Commander of the Order of the Rokel, the highest order of merit of Sierra Leone. This was given by the country of Sierra Leone, in recognition, for having restarted the economy of Sierra Leone with a titanium and a bauxite mine.[35]
