Have to agree with @robbo24 here.

Having such a lien simply means that mining companies based in Tanzania are obliged (and coerced if necessary) to make payment of royalties and taxes to the government.
Given that the graphite at Epanko is already caught by the definition in the current legislation, where is the change in the effect that the new legislation would have?

Secondly, if the government has already granted a mining license, what powers exist to revoke such in the event that the miner complies with all of the terms of the license?
