According to a report reviewed by the United Nations, a Rwandan company called Boss Mining Solution purchased minerals that were smuggled out of rebel-held areas in neighboring Congo. This helped fund an insurgency there. This is the first time that the U.N. has publicly named a company accused of being complicit in the trafficking of minerals looted in Congo after M23 insurgents took over a major mining area in the country last year. Boss Mining is named in a U.N. document that documents how recent territorial gains by M23 in Congo have further destabilized an area beset by decades-long conflict. U.N. accuses the heavily armed rebels of plundering Congo’s natural resources, and of committing atrocities on civilians. They are backed by Rwanda's government. The report stated that illegal mining and smuggling minerals into Rwanda from M23-controlled zones had "reached unprecedented heights". Diplomats said that the report, which was presented to the U.N. Security Council's sanctions committee for Congo at the beginning of May, will be published shortly. M23 has not responded to our requests for comment. Corporate records show that Eddy Habimana is a Rwandan entrepreneur who runs Boss Mining. U.N. investigators had identified Habimana as a minerals trafficker a decade earlier, with ties to rebels fighting in the eastern Congo. Habimana refused to comment on allegations made in an unpublished U.N. Report. According to Rwandan corporate records, two Russian-born mining executives also own Boss Mining. Yolande Makolo said on Wednesday that the U.N. Report "misrepresents Rwanda’s longstanding concerns about security" regarding Hutu groups who have attacked ethnic Tutsis both in Rwanda and Congo. This threat "requires a defense posture in our borders." The Congolese government spokesperson did not respond immediately to our questions, but officials in the Democratic Republic of Congo have accused Rwanda of fomenting conflict to plunder Congo’s mineral wealth. Mineral sales have been crucial to M23's funding. Insurgents swept through large areas of eastern DRC this year, including mines that produce gold, copper and tin, as well as the largest coltan mining operation in the world. An analysis of 2024 customs records revealed that Boss Mining was one of several Rwandan companies exporting significant volumes of coltan, despite the fact Rwanda produces very little of this metallic ore. Rubaya is the Congolese mine area, now controlled by the M23 group, which produces 15% of all the coltan in the world. The ore can be processed into tantalum, a heat resistant metal that is in demand by manufacturers of mobile phones, computer systems, and other electronics, aerospace, and medical applications. M23 insurgents took control of the two main crossings to Rwanda when they seized Bukavu, a border city located on the Congolese side, and Congo. According to a forthcoming U.N. Report, smuggled Congolese mineral are transported to Rwanda through these cities. They do so at night to "avoid detection." According to the report, 195 tons were discovered in just the last week of march. The report stated that Boss Mining purchased some of the minerals. Habimana responded to previous questions in June about Boss Mining operations by saying that his company had "never purchased coltan" from Rubaya. "All materials we purchase are in compliance with international guidelines designed to ensure mining doesn't fund armed group or contribute to abuses of human rights," he added. M23's rapid advance in eastern Congo has reignited a conflict that dates back to the Rwandan genocide of 1994 and has caused millions of people to be displaced. The rebels are determined to topple the Congolese Government. The Rwandan government has denied for years that it is involved in the trade of coltan looted by its neighbor, or that it supports M23. Rwanda's ruling Tutsi majority party shares the same concern as M23 about the alleged threat of rival Hutu groups in eastern Congo. According to a confidential U.N. document, Rwanda had 1,000 troops in Congo as of April. Rwanda and Congo signed on Friday a peace agreement mediated by the United States that will see Rwandan troops withdrawn from Congo. The agreement does not include the M23. The rebel group is a part of an independent, parallel mediation that Qatar leads to try and end hostilities. Success in these talks is crucial to any lasting peace.

MURKY SUPPLY CHAINS An analysis of customs data revealed that Boss Mining exported 150 metric tonnes of coltan in 2024, worth at least $6.6 million. This figure represented 6.5% of all Rwandan coltan exports in 2024. Boss Mining was the sixth largest exporter of ore for the year. According to a Boss Mining worker who requested anonymity because he wasn't authorized to speak with the media, Boss Mining doesn't mine its own coltan, but instead buys it from Speck Minerals and other sellers. According to an employee of Boss Mining and a database online from the Rwanda Mining Board, the company has a mining license in Rwanda's Burera District where they mine wolframite. According to maps and the mining industry press, there are no major coltan mines in that area. According to reports from the Rwanda Mining Association, and the Rwandan mining press, Habimana also represents Speck Minerals. According to a publication from the 2024 Rwanda Mining Association, Habimana also uses this number for Boss Mining. Boss Mining's employee said that Speck operated two mines, in the Gakenke district and Muhanga district of Rwanda. These mines produce a total of 18 tons of colltan per month. In a 2018 audit conducted by a Thai smelter of the Muhanga Mine, the site owner was listed as Eddy Habimana and the mine name was listed as Speck. According to the audit, the production was 2.3 tons per month at that time. Habimana, in response to questions last month about Boss Mining in text messages, described the two mines in Muhanga & Gakenke as being part of Boss Mining operations. Was unable to verify current production at either mine. Habimana refused to answer any questions regarding Speck, or the employee's claims about production. U.N. investigators as well as non-governmental organisations and sources from the mining industry have accused M23 and their Rwandan supporters of smuggling minerals from Congo illegally for more than a decade. According to a U.N. Report published in December 2024, the scale of the trade increased after M23 took Rubaya. The rebels established a parallel government that controlled mining, trade, transportation, and taxation on minerals produced in the area. U.N. 2024 report stated that the rebels had taken Rubaya and established a parallel administration to control mining activities, trade, transport, and taxation of the minerals produced there. U.N. experts said that the resulting mixing of Congolese coltan with Rwandan production is "the most significant contamination of supply chain" to date. According to the report 2024, M23 received $800,000 per month in taxes from the coltan mines in eastern Congo. Mining experts claim that official statistics on Rwanda's production of coltan are not reliable. In May 2024, the central bank of Rwanda suspended publishing export statistics shortly after M23 had seized Rubaya. An analysis of the customs records revealed that Rwanda exported 2,300 tons ore coltan last year. Eleven geologists and mining experts who are based in the area said that Rwanda exports much more coltan than it produces. They have all visited mines and found that the Congo has a much larger mine site and more miners. Bill Millman, a mineral consultant based in the UK, said that Rwanda's coltan exports for 2024 are "totally implausible". Rwanda's government has not commented on its coltan output. In January, the DRC cut diplomatic ties with Rwanda after M23 took over the Congolese capital of Goma. Congo's army has repeatedly struggled to quell Rwanda-backed revolts. Kigali, however, has benefited for years from the corruption in the Congolese minerals trade and the lack of regulation.

RUSSIAN CONNECTION Rwandan records of company show that Boss Mining, which was established in 2013, is owned by Habimana. The managing director denied buying Congolese colltan. These records reveal that Boss Mining also has two other owners, Yuriy tolmatchev (the managing director who denied purchasing Congolese coltan) and Alexander Konovalchik. According to UK and Russian company records, and Russian mining press reports, both men are dual citizens of the UK and Russia and have worked in the mining sector for decades. Now they live and work in Britain. According to corporate records, the two men own other companies which buy the coltan from Boss Mining. They are also directors of Metarex Ltd., according to Cyprus corporate records. According to corporate records from the United Arab Emirates provided by corporate intelligence firm Diligencia, Metarex is 100% owner of Novacore FZE. Tolmatchev manages Novacore, which according to corporate records and an analysis of customs data, purchases all the coltan produced by Boss Mining. Tolmatchev declined to comment on Novacore’s purchases. He stated that Boss Mining was the smallest exporter of coltan in Rwanda but refused to give more details. He said he had no idea what local traders were doing in North Kivu, the Congo province where the Rubaya mine is located. Tomaltchev responded that the company does not buy material from Congo. Konovalchik was not able to comment on the U.N. Report. He said that all minerals purchased by Boss Mining are "from Rwandan Sources". He then referred any further questions to Habimana. He said, "I don't control day-to-day operations." Reade Levinson reported from London, David Lewis from Nairobi, and Sonia Rolley from Paris.
