Anyone heard any more about the drafted changes to Mining Legislation in Tanzania? This is the first I have heard of it and it's not confidence inspiring.

A quote form the article.

"This is unprecedented in terms of an escalation and an assault on the mining sector," said Ahmed Salim, vice president of global advisory firm Teneo Intelligence.
"There hasn’t been much dialogue between the private sector and government. Major companies in Tanzania, both foreign and domestic, mostly wake up to news about major changes in legislation and regulation alterations ... This will have very severe consequences in terms of foreign investment."
