A new mining law, requiring foreign-owned companies to cede a 50 per cent stake to the public in Tanzania, is threatening to cripple the thriving $500 million Tanzanite gemstone business.

One company, TanzaniteOne, has rejected a demand by the government to relinquish half of its shares to the State Mining Corporation (Stamico), setting the stage for a major dispute.
