Societé minière de Bakwanga (abbreviated MIBA ) is a diamond mining company based in the Democratic Republic of the Congo . Historically, the company was the largest diamond producer in the world by volume. However, following decades of decline, the company currently produces only a small minority of the DRC's diamonds.
57-742: MIBA operate near Mbuji Mayi , in Kasai-Oriental Province in south central DRC. Approximately 80% of MIBA's stock is owned by the Congolese government, with 20% owned by Asa Resources Group . During Belgian rule , diamonds were first discovered near the Bushimaie river in December 1918 by George Young, a Scottish geologist employed by the Compagnie du chemin de fer du bas-Congo au Katanga .

The celebration
228-502: A command post that monitored the population, which made indefinite residence in the area almost impossible to establish. There was limited economic activity besides the company-run mining, with even limited agriculture, and the city's population remained low, at approximately 39,830 by the late 1950s. As the city grew, more and more infrastructure needs required investment in roads, public works and hospitals. While several primary schools were developed for workers, until independence, there

In February 2000, the Tshibwe cluster, an 800 square kilometer diamond mining area just south of Mbuji-Mayi in the which contained MIBA's best kimberlite deposits was transferred from MIBA to the joint venture Sengamines [ fr ] . After a failed bid to float

Nzemba was considered one of the more powerful players in Mobutu's political party, the Mouvement Populaire pour le Revolution (MPR), but also called himself a "brother" of Étienne Tshisekedi , a popular local political figure and Mobutu's most significant political opposition. During his time as head of MIBA, Nzemba
456-494: A record production rate with 18 million karats of diamonds. But by 1963, the numbers had fallen dramatically in the wake of years of turmoil, including an attempt to establish the region as the independent Mining State of South Kasai . In that year, the company produced just 1.4 million karats of diamonds, almost all of them industrial diamonds. By contrast, between 4 million and 6 million karats of diamonds were produced by diamond smugglers who had previously been tightly controlled by
513-806: A relationship with De Beers consortium, allowing the Oppenheimers to import the DRC's diamonds to London. Starting in 1967, exclusive purchasing rights for Zaïre's diamonds was given to British Diamond Distributing Ltd. (Britmond).

However, in April 1981, Mobutu announced that the Zaïre's state-owned Société Zaïroise de Commercialisation des Minérais (Sozacom) would be taking over international marketing of

912-607: The Asa Resources Group ). In 2007, diamond exports fell by 80%. There was significant insecurity at the mine, with an engineer responsible for running a new $ 10 million dragline excavator , and a security guard both murdered. About 10,000 artisanal miners trespassed onto the mining site every day, and employees had not been paid for more than four months. In October 2008, the MIBA employees went on strike several times for not being paid for more than 20 months. Production

In 1956, MIBA also discovered the Tshibwe cluster of kimberlite pipes, and mined these for a while. In the 1950s, it was estimated that the city, then known as Bakwanga, and its surrounding area had the world's most important deposit of diamonds, with at least 300 million karats. While about 95% of

However, no buyout actually occurred, and the ultimate beneficiary of Oryx's stake

As of 1963, Mbuji-Mayi-based MIBA was the source of 80 percent of the world's industrial diamonds and 57 percent of all diamonds. Mbuji-Mayi grew rapidly upon Congolese independence in 1960 with the immigration of members of the Luba ethnic group from different parts of the country. Shortly after independence, Albert Kalonji ,

According to the Congolese Ministry of Mines, MIBA is one of only two industrial diamond mining companies in the DRC in 2023. However, the vast majority of diamond production in the country is attributed to artisanal miners or the other industrial miner, Anhui Congo Mining Investment Company (SACIM). MIBA has

Nzemba, who was appointed by Mobutu in 1986, was considered one of the more powerful players in Mobutu's political party, the Popular Movement of the Revolution (MPR), but he also called himself a "brother" of Étienne Tshisekedi , a popular local political figure and Mobutu's most significant political opposition. Nzemba

However, Mbuji-Mayi is the traditional centre of industrial diamond mining in Congo, with it being located on top of one of the largest known deposits in the world. Air travel is provided through the Mbuji Mayi Airport . Mbuji-Mayi is made up of five communes (municipalities), each headed by
1539-658: The city's main business remains the diamond trade. In January 2015 there was an outbreak of tuberculosis (TB), including multi-drug-resistant TB in the Mbuji-Mayi Central Prison. The CDC investigated and found the prison was filled to six times its capacity giving each prisoner a fixed spot less than about 0.25 square meters (2.7 square feet) in a cell. About half of the inmates were malnourished . These conditions, combined with poor ventilation, lack of sunshine, and lack of TB screening, had allowed TB to spread for years. Amnesty International published

Nzemba was also summoned to Goma to speak with Kabila, who held him for several days, prompting his family to purchase advertising in newspapers publicising their concerns for his safety. Nzemba was released shortly after, but MIBA began making "voluntary contributions" to Kabila's war, an estimated $ 5.5 million in 1997 and 1998. In October 1998, Mbuji-Mayi

In 1962, Mibeka created the Societé Minière de Bakwanga (MIBA) as a subsidiary. This

The city had always been a major source of the world's diamonds and that did not change after independence, nor did the age-old tradition of diamond smuggling. But after independence, that ability of the government to control the diamond smuggling quickly eroded and diamond smuggling dramatically increased. The black market quickly eclipsed the official business, and in 1963, MIBA officially recorded producing 1.4 million karats of diamonds, while smugglers exported between 4 million and 6 million more karats. The city lacks much of

Based in the city of Mbuji-Mayi, formerly Bakwanga, the company provided as much as 80 percent of the world's industrial diamonds, but other than mining operations which provided much-needed hard currency, the region was widely neglected by Mobutu and the central government. Throughout the 1980s and 1990s, Zaire and Mobutu paid little attention to Mbuji-Mayi, offering almost no money to build roads, schools or hospitals. In

Following the discovery, a mining camp designed to house miners and company officials of the Societé minière de Bakwanga (MIBA) was developed in the area.
