Just a nit pick... they are sourcing from Rwandans... which is the first sign that they are dealing with bad guys. The materials they get from the Rwandans have come from the Congo... where the Rwandans ethnically cleanse areas so that they can mine the minerals.
So technically... the materials they source from the Rwandans are conflict materials procured from genocidal Rwandans... not really materials procured through child labor.
Of course... that just means it's much WORSE than child labor... I just thought people should have the facts straight more as a matter of principle.
You can start by googling Laurent Nkunda. To get a feel for what the Rwandan backed militias who loot these mines are like. Fair warning... that reading is really not for the timid though.
You can read background on the actual technical and logistical aspects of the mineral trade from Nest. The book is titled "Coltan".
If you want the actual dry but raw data of the UN reports there are several which touch on the DRC mineral situation, and they are all at the UN's site. (They only go back to 2004... to go further you'd actually have to get it out of google cache. But obviously the UN has compiled reports going back much further for the purposes of future Crimes Against Humanity prosecutions.) In any case, you can find them here:
