The whole mess has more to do with the dispute between Acacia mining and the Tanz government. It seems they have rushed through legislation to deal with that. Every other miner is collateral damage. I agree that governments should benefit with their fair share of the mining spoils. But the recent amendments are so draconian as to be more of a hindrance than actually benefiting the state. So much so that I fear that no one in their right mind will now invest in Tanzania. Sovereign risk at its finest!
