Early life and education[edit]

Jean-Raymond Boulle was born in Mauritius in 1950, attended Marist Brothers Rondebosch school in Cape Town and, later, the University of Dallas.[citation needed]


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.[citation needed]

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.[citation needed]

Boulle was chairman, founder and CEO as well as a major shareholder of Diamond Fields (Diamond Fields Resources Inc. TSE:DFR)[1] 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.[2] 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.[3]

Boulle's next company, Diamond Fields International is involved in sea floor mining with interests in mining deposits around the world.[4][5][6]

His Boulle Mining Group[7] 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 with dual listings on the Toronto Stock Exchange and the London Stock Exchange.[citation needed]

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.[citation needed]

Boulle Mining Group Luxembourg was the largest shareholder in World Titanium Resources,[9] the Australian Securities Exchange listed[10] discoverers and owners of the Toliara Sands[11] 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.[citation needed]

Together with the Government of Mauritius, Boulle is one of the three controlling shareholders of Omnicane,[12] a publicly listed company on the Stock Exchange of Mauritius. Omnicane owns sugarcane plantations in Mauritius and produces refined sugar. Omnicane also generates around 40% of the island's electricity needs.[citation needed]

Boulle's companies have conducted mining and exploration operations for gold, copper, nickel, zinc, and diamonds and other precious and semi-precious stones in South Africa, Namibia, Liberia, Madagascar, Democratic Republic of Congo, Zambia, Finland, Canada, and Brazil.[citation needed]

The award was made to Boulle by His Excellency Alhaji Ahmed Tejan Kabba, the President of the Republic of Sierra Leone.[14] in recognition for having restarted the economy of Sierra Leone with a titanium and a bauxite mine.

On 2 December 2014, the Boulle Group's Tendyne Holdings Inc.[15] start-up company announced the world's first[16] successful Human Heart Mitral Valve implants at the Royal Brompton Hospital in London, England.

This acquisition culminated a relationship that began when Jean Boulle Medtech welcomed Abbott Laboratories as an early strategic investor in Tendyne. Jean Boulle Medtech worked with Tendyne's most recent investor, Apple Tree Partners, in helping to complete the transaction. Since the acquisition, Jean Boulle Medtech's research and investment in other new, cutting edge areas of medical discovery has continued.
