Uranium Resources Commences Exploration Drilling in South Texas

Uranium Resources Inc. (NASDAQ: URRE) has commenced exploration drilling at its Butler Ranch Project and is expected to conduct drilling at the Alta Mesa Project by the end of the first quarter of 2015. The Company expects to invest $0.8 million on exploration drilling at the Butler Ranch and Alta Mesa Este projects in South Texas in 2015.

These two projects were part of a non-cash, strategic land exchange completed in November 2014 that augmented the Company’s project development pipeline. All five projects acquired through the land exchange are located near the Company’s temporarily idled processing facilities at Kingsville Dome and Rosita in South Texas.

Christopher M. Jones, President and Chief Executive Officer, said, “We are excited to incorporate a substantial exploration drilling program on two of our five new South Texas projects in 2015. The Butler Ranch and Alta Mesa Este projects as well as the Sejita Dome Project are high quality, mid-term in-situ recovery (ISR) projects within the highly prospective South Texas uranium province. While initiating this important South Texas exploration program, we have also been able to further reduce the Company’s cash spend rate to an estimated $9 million for 2015.”

Butler Ranch Phase One Drilling

The 2,592-acre Butler Ranch Project is located in the prolific Karnes County mining district, and is 75 miles north-northeast of the Company’s Rosita processing facility. Historic open pit mining of uranium deposits (situated above the water table and not amenable to in-situ recovery methods) occurred in the area from the 1950s through the 1970s by Conoco, Susquehanna-Western, Pioneer Nuclear and Chevron.

The initial Butler Ranch drilling program, which is comprised of between 4 and 6 holes (up to a total of 2,100 feet), is designed to test for uranium mineralization beneath the water table, which would be suitable for in-situ recovery methods. Drilling is planned to evaluate the southwesterly projection of uranium mineralization within the Jackson Group sandstones, which is the host structure of several known uranium deposits in the area.

Upon completion of rotary drilling at the Butler Ranch Project, the drill rig will be moved to the Alta Mesa Este property for a major 40-hole exploration drilling program there.

Alta Mesa Este Phase One Drilling

The 2,841-acre Alta Mesa Este Project is located about 56 miles southwest of the Company’s Kingsville Dome processing facility, and is a short distance northeast of Mesteña Uranium’s Alta Mesa processing plant and well fields. The Alta Mesa Este phase one drilling program is designed to test for the presence of roll-front uranium mineralization in the Goliad Formation, which is the host rock for the nearby Alta Mesa mine.

Drilling of up to 24,000 feet in approximately 40 holes is planned along a 1.5 mile east-west trending target zone, which was previously drilled by Chevron Resources in the early 1980s. The drill holes at Alta Mesa Este will range from 450 to 600 feet in depth. The Company expects to advance the Alta Mesa Este Project with aggressive drilling to target development of preliminary ISR production within three to five years.

2015 Cash Expenditure

The $0.8 million exploration investment is part of an expected $9 million cash budget for cash general and administrative and mineral property expenditures for 2015. The expected 2015 cash expenditure is 23% lower than the $11.6 million (unaudited) in expenditures in 2014 and is almost half of the cash spent of $16.8 million¹ in 2012. During the third quarter of 2014, the Company achieved its goal of reducing its cash burn rate to under $1.0 million per month and has further tightened its expected expenditures in 2015 while funding an exploration program.

The Company’s cash and cash equivalents totaled $5.6 million at the end of 2014. The Company expects to report its fourth quarter and full year 2014 results on March 19, 2015.
