Not intending to downramp here - just interested to see if anyone has any thoughts on ethical investment considerations with this stock - surely a question that is bound to emerge sooner or later if it hasn't already. I think its fairly common knowledge that the DRC has a long history of foreign exploitation going hand in hand with government corruption. It also has one of the greatest disparities between living conditions and mineral wealth on Earth (ie vast mineral wealth + extreme poverty) .

What do you think?
