Looks like there will be something on mining in Ghana, to do with Canadian mining companies cracking down on citizens doing their own mining on CBC News Sunday this morning, and possibly on CBC News Sunday Night as well.
UPDATE: I've just watched it this morning. The name of the company is Golden Star Resources. According to the documentary, in the past they've also used cyanide that has affected local drinking water. The documentary also touches on the fact that Canadian mining companies lead the world in international mining projects, and that human rights abuses often take place.
