UPDATE: The main complaint seems to be that the dirt track road used by the mining companies has been kicking up enormous amounts of dust due to the quantity of trucks now using the road. Locals have complained for months about this and how the dust is a pollution risk as well as contaminating their nearby crops. The mining companies pledged to pave the road on several occasions but after each agreement, nothing happened. Therefore locals feel forced to take action by blocking the roads.
