Deposits of tantalum and niobium are rare.

Most of the world’s tantalum supply currently comes from a single mine in Australia, with a few sources in Africa, Asia and South America. Secondary sources include recycled materials, processor inventories, tin slags, and the United States Defence Logistics Agency stockpile, which is now severely depleted.

As for niobium, the DLA stockpile of niobium mineral concentrate inventory was exhausted in 2007, its niobium carbide inventory was exhausted in 2002, and its ferroniobium inventory was exhausted in 2001. With only 20% coming from secondary sources such as recycling, niobium also enjoy strong fundamentals.
