Treasury sanctions Rwandan gold refinery over conflict minerals
On June 25, 2026, OFAC sanctioned Gasabo Gold Refinery, two executives and three mining firms over gold allegedly sourced from M23-held areas of eastern DRC.
The news
On June 25, 2026, the Treasury Department’s Office of Foreign Assets Control imposed Treasury sanctions on a Rwanda-based gold refinery and a related network that it said laundered conflict gold from the eastern Democratic Republic of the Congo.
The designations covered Gasabo Gold Refinery LTD; its chairman, Jean Malic Kalima; its general manager, Bosco Kayobotsi; and three companies Treasury said Kalima controls: Bugambira Mines LTD, Wolfram Mining and Processing LTD, and Rwinkwavu Mining Corporation LTD.
OFAC acted under Executive Order 13413, as amended, citing material support to the M23 armed group and support to armed groups involved in illicit natural resource trafficking that threatens peace and security in the DRC. According to Treasury, gold was extracted from M23-controlled mining areas in South Kivu and moved across the border into Rwanda with the involvement of Rwanda Defence Force soldiers and M23 fighters. Gasabo then refined it. Treasury said the refinery laundered approximately 60 kilograms of gold in early 2026 and that the operations funded M23’s activities. The release referenced coordination with the State Department under the Washington Accords framework.
As with other designations, property and interests of the sanctioned parties in the United States are blocked, U.S. persons are generally prohibited from dealing with them, and violations can bring civil or criminal penalties.
Our analysis
Why Treasury sanctions target the refining step
Refineries are the choke point in a gold supply chain. Before refining, gold from a particular mine can often be traced by its characteristics and paperwork. After refining, it becomes a standardized product that is far harder to link to its source. By targeting the refinery rather than only armed groups or individual traders, Treasury aimed at the point where conflict gold would otherwise become indistinguishable from legitimate metal.
The inclusion of the mining companies matters for compliance teams. These entities could provide a paper trail suggesting gold originated in Rwanda rather than in M23-held territory in the DRC. Designating them alerts banks, traders and refiners that documentation tied to these firms carries sanctions risk.
The action also has implications beyond U.S. borders. OFAC designations are widely screened by international banks, so blocked parties can find it difficult to access dollar clearing or transact with global institutions even outside the United States.
For financial institutions, the practical step is screening: updating sanctions lists, reviewing any exposure to the named entities and individuals, and examining trade finance or precious metals transactions with links to the region.
The 60-kilogram figure Treasury cited for early 2026 gives a sense of the volumes at stake in a short period. Gold is compact, high in value and easy to transport, which is why it has long been attractive to armed groups seeking to finance operations. Sanctioning the companies that turn raw ore into tradeable metal is one of the few levers available to authorities far from the mines themselves.
Room for disagreement
Some observers question how much sanctions on a single refinery can disrupt a trade that has historically adapted by shifting to new intermediaries. If gold is rerouted through other refiners or jurisdictions, the effect may be temporary.
There is also a diplomatic dimension. Treasury’s description directly implicates Rwanda Defence Force soldiers, which could complicate regional diplomacy even as the action was presented as aligned with a broader peace framework.
Supporters would respond that targeting the refining step raises costs for the entire network and gives private-sector compliance programs concrete names to act on.
