    Uranium Resources Commences Lithium Exploration Drilling at the Columbus Basin Project



    CENTENNIAL, Colo., July 31, 2017 (GLOBE NEWSWIRE) -- Uranium Resources, Inc. (Nasdaq:URRE) (ASX:URI),

    an energy metals development company, is pleased to announce the commencement of exploration drilling activities at its Columbus Basin lithium brine project. The planned Phase I drilling program at the project will consist of five (5) core holes, and a total of 8,000 feet (2,440 meters) of drilling. Drill targets for this program are based on completed surface sediment sampling (see news releases dated February 22, 2017 and July 12, 2017), and interpretation and analysis of multiple geophysical data sets covering the project area (see news release dated April 5, 2017).
    “We are excited about the potential that our Columbus Basin Project presents and this first round of drilling and evaluation of those results will provide a path forward for further work,” said Chris Jones, President and CEO of URI. “Development of our lithium exploration and development business is a high priority for the Company.”

    Phase I Drilling Program

    The Phase I drilling program at the Columbus Basin Project consists of five (5) core holes drilled to depths ranging from 1,500 feet to 2,000 feet to test the local brine aquifer system for lithium content.

    Brine samples will be collected as the core holes are advanced, and if the screening samples indicate favorable lithium concentrations the core holes will be reamed to a larger diameter and groundwater wells will be completed. Completed groundwater wells will be sampled, and dynamic testing completed to determine the hydraulic properties of the aquifer. The planned exploration operations have been permitted through the Bureau of Land Management and the Nevada Division of Water Resources.

    The drilling contractor, Harris Exploration Drilling & Associates Inc., has mobilized to the project site and commenced drilling operations at the first drill site.

    Geology, hydrogeology and brine sampling activities will be directly managed in the field by Matt Hartmann, M.Sc., P.G., and Director of Technical Services for URI.

    All brine samples will be collected in duplicate for analysis at the Company’s laboratory at the Kingsville Dome facility and a qualified independent analytical laboratory.

    Results of this drilling program are expected to be available in the 4th quarter of this year.

    About URI’s Columbus Basin Project

    The Columbus Basin Project is located within the Columbus Salt Marsh basin of western Nevada, approximately 45 miles (72 kilometers) west of the town of Tonopah, Nevada, 140 miles (227 kilometers) southeast of the city of Reno and 137 miles (221 kilometers) southeast of Tesla Motors’ “Gigafactory.” The Columbus Basin Project is approximately 27 miles (43 kilometers) northwest of the Clayton Valley/Silver Peak lithium brine operation of Albemarle Corporation, the only lithium brine production facility in the United States.

    The Columbus Salt Marsh is a closed drainage basin that covers an area of approximately 370 square miles (960 square kilometers) with a geologic setting that is dominated by lake and basin-fill sediments that have been past sources of borate and salt production. The basin is bounded on its south and east sides by Tertiary-age volcanic rocks, including some that are considered to be potential source rocks for lithium.

    The initial 11,200 acres of the Columbus Basin Project was acquired through staking in 2016, and is 100% owned by URI through its subsidiaries. Acquisition of additional federal mineral claims covering 3,040 acres in March 2017 was completed through an option agreement with a private party. URI controls over 14,200 acres in total at the Columbus Basin Project. The Company is presently advancing the project through a series of exploration activities to determine the potential for economic concentrations of lithium within the subsurface brines of the basin.
