TMRC’s Round Top Project Contains Significant Quantities of Rare Earth Minerals Necessary to the Production of Rare Earth Magnets

• Recently enacted National Defense Authorization Act for FY 2019 prohibits the U.S. Department of Defense from acquiring rare earth magnets from China
• TMRC’s Round Top project potentially supplies all of the U.S. Department of Defense rare earth magnet needs

SIERRA BLANCA, Aug. 15, 2018 - Texas Mineral Resources Corp. (OTCQB: TMRC), an exploration company targeting high value tech metals including rare earths and a variety of other high-value elements and industrial minerals, is pleased to announce that our Round Top deposit, located eighty-five miles southeast of El Paso, Texas, contains all of the rare earth minerals necessary for the production of rare earth magnets as defined by the recently signed FY19 National Defense Authorization Act (NDAA).

Section 871 of the NDAA, signed into law on August 13th, specifically requires that all rare earth magnets and tungsten be melted or produced in nations other than China, Russia, Iran and North Korea.

At full production, the Round Top project would potentially produce annual quantities of the following four rare earth minerals necessary in the production of rare earth magnets:

· Neodymium: 230 metric tons per year

· Praseodymium: 87 metric tons per year

· Dysprosium: 208 metric tons per year

· Terbium: 26 metric tons per year

“With China as the world’s largest rare earths producer and U.S. production currently at zero, the defense bill underscores the importance of developing a stable source of domestic rare earth supply,” said Anthony Marchese, TMRC Chairman. “Rare earth minerals are used in every major U.S. advanced weapons platform, from guidance and control systems and electronic warfare to targeting systems, electric motors and communications, command and control.”

Based on a Congressional Research Service report issued in 2011 titled “Rare Earth Elements in National Defense: Background, Oversight Issues, and Options for Congress” and authored by Valerie Bailey Grasso, it is estimated that Round Top could potentially supply virtually all of the rare earth magnet raw material needs for Department of Defense contractors.

Round Top is a National Instrument (NI) 43-101 compliant, one billion tonne mass of uniquely mineralized rhyolite with an estimated mine life of over 100 years, whose metals could potentially be extracted by low cost heap leaching. Its location near El Paso on state property and existing infrastructure may allow this deposit to be brought into production relatively quickly.
