NioCorp Developments Ltd said Monday it had received “conditional approval” to receive $100 million in tax incentives for its proposed rare metals mine in southeast Nebraska. The incentives would come from the Nebraska Advantage program, which offers qualifying companies tax rebates for hitting set targets for investment and job creation. The project NioCorp would receive these incentives for is a proposed mine near Elk Creek in Johnson county. It would extract niobium, scandium, and titanium. The mine has the potential to create $17.6 billion in revenue over a 32 year life and about $390 million of annual pre-tax income.
