$URRE New Energy Metals Business #Acquires Its First #Lithium Property in #Nevada

CENTENNIAL, Colo., Aug. 23, 2016  — Uranium Resources, Inc. (URI)  (Nasdaq:URRE) (ASX:URI), announced today that it has staked approximately 4,600 acres (1,860 hectares) of placer mining claims covering a prospective target for lithium-enriched brines in the Columbus Salt Marsh area of west-central Nevada. The target area, known as the Nina Project, is situated within a region of known lithium mineralization and is approximately 27 miles (43 kilometers) northwest of the Clayton Valley/Silver Peak lithium brine mine of Albemarle Corporation, the only operating lithium brine recovery operation in the United States.

The acquisition of the Nina Project signals URI’s intent to expand and broaden our corporate efforts into other energy metal commodities, synergistic with the Company’s existing business operations and technical capabilities, in order to create increased shareholder value through exposure to rapidly expanding global energy demand.  URI has advanced its internal program of target identification, exploration and evaluation rapidly, and is now actively acquiring lithium prospects to build a robust and prospective lithium project portfolio.

About the Nina Project:

The Nina Project is located approximately 45 miles (72 kilometers) west of Tonopah, Nevada, is bordered by US highways 6 and 95, and is located near electrical power. The target was initially identified by Company staff through literature reviews of historical geological and geochemical data from the US Geological Survey as well as other information sources, followed by field reconnaissance of the target area. Geochemical sampling returned lithium assay values from near-surface brines that ranged up to 70 and 124 parts per million (ppm) lithium, as determined by the Company’s Kingsville, Texas analytical laboratory and by ALS Minerals in Reno, Nevada, USA. Sediment samples collected from the target area ranged from 98 to 176 ppm lithium as determined through geochemical analyses carried out by ALS Minerals. These assay results generally confirm several of the lithium values from samples collected by the US Geological Survey in 1976, and indicate the target area warrants additional investigation to further characterize the subsurface environment.

The Columbus Salt Marsh, site of the Nina project, is a closed drainage basin covering an area of approximately 370 square miles (960 square kilometers) and whose geology is dominated by lake and evaporite sediments that have been sources of borate, potash and salt in the past.

Near term investigations at the Nina Project will focus on the chemical characterization of the lithium bearing brine aquifers, as well as the vertical and lateral extent of lithium-bearing brines.

The nearby Clayton Valley (27 miles southeast) is the site of Albemarle Corporation’s Silver Peak lithium-brine mine; the only lithium brine production facility in the United States, which produces approximately 6,000 tonnes of lithium carbonate annually.  The Columbus Salt Marsh is geologically similar to the Clayton Valley, and provides URI with a cornerstone project from which a complete lithium resource portfolio can be built.

About the Lithium Market

Lithium is a critical component for the manufacture of batteries for electrical storage and used in a wide range of devices ranging from cell phones to automobiles.  The battery market is expected to grow 500% over the next 10 years, with lithium batteries accounting for 35% of this growth. At the same time, the transportation sub-market alone is expected to experience a 23% compounded annual growth rate during this same period.

With large battery plants such as Tesla’s “Gigafactory” near Reno, Nevada and Faraday Motor Works’ proposed facility near Las Vegas, Nevada – URI’s Nina Project is at the epicenter of lithium brine development, production and consumption in the United States.

Lithium enriched brines are proven to be less expensive to explore for, develop and operate than other sources of lithium, such as lithium rich pegmatites and hectorite clays.  This advantage of brines is coupled with a small environmental footprint and minimal carbon emissions, which makes ISR mining of brines an attractive method for producing lithium.

Taking advantage of URI’s Expertise

With nearly forty years of corporate experience in the development, operation and restoration of ISR uranium recovery operations, URI is uniquely qualified to expand its business ventures into the lithium brine business. URI is positioned to take advantage of its extensive expertise in:

• Design, construction, and operation of well fields;
• The extraction and recovery (hydrometallurgy) of metals from groundwater;
• Exploration of mineral properties; and
• Permitting of new projects on privately-owned properties and lands administered by the US Bureau of Land Management and the US Forest Service.

The URI team has successfully explored for a wide range of mineral commodities, from industrial and agricultural minerals, precious metals, uranium and, now, lithium, in the United States and throughout the world. Using a disciplined approach, URI has centered its geological focus to locales, like the Columbus Salt Marsh, that fit a preferred geologic criteria and have the potential to host economic resources of lithium.  Furthermore, the Company’s decades of wellfield design, management, and hydrometallurgical operations experience is directly transferrable to lithium brine extraction and processing. In addition, the Company’s existing facilities also present value in a diversification into lithium, as demonstrated in the use of the existing in-house analytical laboratory at the Kingsville Dome Mine to provide rapid analysis of brine screening samples collected as part of ongoing exploration and evaluation activities.

Christopher M. Jones, President and Chief Executive Officer, said, “Expanding our business into lithium brine exploration and development is a logical next step for URI and capitalizes on our wide range of experience. Diversifying our mineral portfolio while maintaining our uranium business portfolio in readiness for the predicted price rise allows investors increased exposure to the energy industry. We are excited about this new chapter for URI.”
