According to some accounts, MPA was the parent company of Mining Processing Congo, a small cassiterite buyer and exporter in Goma. Rwandan helicopters were seen landing in the area directly exchanging arms for cassiterite ore. By November, senior Rwandan Army officers were deployed to the Kilambo airstrip in order to provide security for cargo planes that were delivering arms to the Congo and taking ore back to Kigali. A recent UN Panel of Experts report stated that any comptoir who knowingly purchases cassiterite from mines controlled by sanctioned armed groups is violating the UN Arms Embargo on Congo.
