June 25 (UPI) -- The U.S. Army has awarded provisional contracts to several companies for processing critical minerals at military bases in the United States.

The Pentagon has reached agreements with at least four companies to build and operate the plants, which will handle rare Earth minerals such as graphite, lithium and boron, Bloomberg and The Wall Street Journal reported.

The four companies -- REalloys, Inc., Titan Mining Corp., ioneer Ltd. and Energy Exploration Technologies Inc. -- are part of the Army's strategic capital initiatives to improve critical minerals availability for advanced manufacturing, the branch said when it released a request for proposals in May.

The locations that the projects are being planned for include locations in Alabama, Arkansas, Texas and Utah, so far.
