“The completion of this expanded PEA is a key milestone in our mission to establish Round Top as not only a robust and reliable provider of the full range of rare earths, but also a supplier of critical tech metals and industrial minerals from the same deposit,” said Dan Gorski, President and CEO of TMRC.  “We believe that the new PEA confirms our vision that a low-cost open pit heap leach operation is as applicable to Round Top’s unique mineralogy in the rare earths and tech metals sectors as it has been to gold and copper operations. As a result of its unique geology and mineralogy, the Round Top deposit should be ideally suited for high volume, low cost surface mining and heap leaching. This combined with the essentially zero stripping ratio, the availability of nearby flat and even topography for leach fields and the presence of nearby rail facilities, power and water, creates an operational and logistical opportunity. Given that we’ve expanded this PEA to assess not only Round Top’s rare earths, but the deposit’s projected production of lithium, uranium, beryllium, gallium, hafnium and zirconium – all of which are on the U.S. Government’s Critical Minerals List – we’re pleased that it appears we can recover such a wide range of critical minerals with an overall estimated CapEx of only $350 million.”  

“This updated and expanded PEA not only confirms potential robust economics and an optimistic outlook for the Round Top project, but also could provide the United States and its allies a means for fulfilling their stated goal of providing a long-term source of critical materials required for defense applications and advanced technology manufacturing capabilities, without the sole reliance on China to provide these materials,” said Pini Althaus, Chief Executive Officer of USA Rare Earth. “The tech metals at Round Top, including lithium, also provide a domestic option for the electrical vehicle sector and clean technology and energy storage applications.”

Overview of the Round Top Project and PEA

The PEA has been completed based on the Measured, Indicated and Inferred Resource Estimate Technical Report originally filed on June 22, 2012 by Texas Rare Earth Resources and updated with the publication of this PEA.  The resource was estimated by Gustavson Associates of Lakewood, Colorado. The resource incorporated into the current mine plan totals 364,000 measured and indicated tonnes and an additional 735,000 inferred tonnes of a combination of rare earth minerals, technology metals and industrial minerals.  A summary of the operating assumptions and financial model for the project is as follows:

Mineral Pricing and Marketing Considerations

In developing rare earth pricing assumptions, Texas Mineral Resources utilized currently available spot prices of rare earth oxides, tech metals and industrial minerals derived from Asian Metal Pages July 2019 prices, Alibaba June 2019 prices and industry communication. Certain rare earth oxides, although produced, will not be marketed for sale due to poor market conditions and are NOT included in the economics of the PEA.  Instead they will be warehoused until such time as market conditions improve.

“We are encouraged by the results of the updated PEA and plan to move aggressively forward to complete a pre-feasibility study followed shortly thereafter by a bankable feasibility study.  At current mineral pricing the Round Top project continues to demonstrate favorable economics. The revised PEA significantly diversifies TMRC’s expected revenue stream and maintains strong potential profitability while lessening the dependence on any single stream to achieve project success,” commented Anthony Marchese, chairman. “We should have the ability to satisfy the urgent need in the U.S. to establish a rare earth supply chain, provide an inroad into supplying technology metals into the electric vehicle and green energy market and utilize Round Top’s proximity to rail and road transport to supply industrial minerals into the domestic U.S. market.  Given the projected 100+ year mine life, Round Top has the unique potential to serve as a reliable long-term partner to both the U.S. government and multiple essential industries.”

Cautionary Note to Investors
The United States Securities and Exchange Commission ("SEC") limits disclosure for U.S. reporting purposes to mineral deposits that a company can economically and legally extract or produce. This press release uses certain terms that comply with reporting standards in Canada and certain estimates are made in accordance with Canadian National Instrument NI 43-101 ("NI 43-101") and the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") - CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (the "CIM Standards"). NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosures an issuer makes of scientific and technical information concerning mineral projects. This press release uses the terms "resource," "measured and indicated mineral resource," and "inferred mineral resource." We advise U.S. investors that while these terms are defined in accordance with NI 43-101 such terms are not recognized under the SEC's Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with the SEC. Mineral resources in these categories have a great amount of uncertainty as to their economic and legal feasibility. "Inferred resources" have a great amount of uncertainty as to their existence and, under Canadian regulations, cannot form the basis of a pre-feasibility or feasibility study, except in limited circumstances. The SEC normally only permits issuers to report mineralization that does not constitute SEC Industry Guide 7 compliant "reserves" as in-place tonnage and grade without reference to unit measures. Under SEC Industry Guide 7 standards, a "final" or "bankable" feasibility study is required to report reserves, the three-year historical average price is used in any reserve or cash flow analysis to designate reserves and all necessary permits and government approvals must be filed with the appropriate governmental authority. The PEA is not a definitive feasibility study and our Round Top project currently does not contain any known proven or probable ore reserves under SEC Industry Guide 7 reporting standards. The results of the PEA disclosed in this press release are preliminary in nature and include inferred mineral resources that are considered speculative geologically to  have the economic considerations applied to them that would enable them to be categorized as mineral reserves and there is no certainty that the  results of the PEA will be realized. U.S. investors are urged to consider closely the disclosure in our latest reports and registration statements filed with the SEC. You can review and obtain copies of these filings at http://www.sec.gov/edgar.shtml. U.S. Investors are cautioned not to assume that  any defined resource will ever be converted into SEC Industry Guide 7 compliant reserves.
