Uranium Resources, Inc. Provides Update on New Mexico Assets

    LEWISVILLE, Texas--(BUSINESS WIRE)--Feb. 23, 2007--Uranium
Resources, Inc. (OTCBB: URRE)

    --  Roca Honda historic estimate of mineralized uranium material
        increased to 15.3 million pounds U3O8 from 5.0 million.

    --  Pre-feasibility study for conventional mining & milling being
        completed

    Uranium Resources, Inc. (OTCBB: URRE) ("URI") announced today that
it has increased its historic internal estimate of mineralized uranium
material for sections 13, 15, and 17 at the Roca Honda Project
(Township 13N, Range 8W) from 5 to 15 million pounds U3O8 as a result
of the previously announced re-evaluation of the Company's extensive
New Mexico database. URI also owns the mineral rights to several other
sections at Roca Honda, but does not own the data on these properties.
Further evaluation of those sections could lead to additional
increases.

    The Company's historic estimates are based on 629 drill holes logs
and were calculated by Kerr-McGee using the circle tangent method. The
current estimate totals 15.34 million pounds of U3O8 contained in 3.9
million tons of ore with an average grade of 0.198%. A significant
quantity of the mineralization is high grade primary ore.
Mineralization occurs as uranium-humate cemented sandstones in
elongated deposit formations that range in width from 50 to 200 feet
wide, are from 200 to over 1000 feet in length, and range from 1 to 20
feet thick.

    URI acquired the Roca Honda deposit along with surface agreements
from the Santa Fe Railroad Company in 1998. The Company does not
believe these properties are Indian lands. Roca Honda is adjacent to
the Mount Taylor Mine owned by Rio Grande Resources, a subsidiary of
General Atomics.

    Because of the ores shapes, locations and depth, and the
significant faults and fractures in the area, the Roca Honda deposit
is better suited to conventional mining than in-situ recovery methods.
There is a pre-existing 14-foot shaft on Section 17 that was sunk by
Kerr-McGee in 1979-80 to a depth of 1,474 feet. Due to declining
uranium prices at the time, the shaft was never opened to the ore and
is now plugged at the surface.

    URI expects to complete by mid-March an internal pre-feasibility
study to evaluate the cost of conventionally mining and milling the
uranium at Roca Honda, as well as the Company's West Largo and Nose
Rock uranium deposits. As part of this process the Company's historic
estimates of mineralized uranium materials at both West Largo and Nose
Rock are being reviewed. The study will evaluate all three properties
as conventional underground mining targets and rank them based on our
estimates of projected cost. In addition to the Roca Honda shaft
referenced above, the Nose Rock property has an 18 foot production
shaft and a 14 foot ventilation shaft completed to a depth of 3,300
feet. It is assumed mined ore will be milled at a large regional mill
that will service several area producers.

    Dave Clark, President and Chief Operating Officer of URI,
commented, "The significant increase in the size of the Roca Honda
deposit now gives the company a sufficient base on which to begin
development of its New Mexico conventional mining and milling
properties. We are now working on a course of action to aggressively
develop these assets."

    In addition, URI expects to complete its review of the Company's
extensive geologic and mining database by the end of June. This
database includes more than 16,000 drill logs, calculations of
mineralized uranium material and mine development plans that were
developed by Phillips Petroleum, Westinghouse, Kerr-McGee, Homestake
Mining, Mobil Oil and United Nuclear.

    Mr. Clark added, "The ongoing review of our database to locate and
quantify uranium deposits on our 183,000 acre land position has
already led to the significant increase in mineralized material at
Roca Honda. We expect additional increases to be made in Company owned
holdings in coming months. We are particularly interested in
identifying smaller ore deposits on checkerboard land throughout the
Ambrosia Lake district that URI obtained as part of the Santa Fe
Railroad Company land acquisition. We have already identified several
smaller deposits of up to several million pounds each that may have
been too small to develop as underground mines, but now appear
amenable to lower cost ISR mining. Put together, these deposits could
lead to the development of a major new ISR project in the Ambrosia
Lake District."

    ABOUT URANIUM RESOURCES, INC.

    Uranium Resources Inc. explores for, develops and mines uranium.
Since it's incorporation in 1977, URI has produced over 7 million
pounds of uranium by in-situ recovery (ISR) methods in the state of
Texas where the Company currently has ISR mining projects. URI also
has 183,000 acres of uranium mineral holdings in New Mexico that
includes the proposed ISR project at Churchrock. The Company acquired
these properties over the past 20 years along with an extensive
information database. URI's strategy is to capitalize on the strong
global market for uranium by fully exploiting its resource base in
Texas and New Mexico, acquiring new assets and through joint ventures
or partnerships.

occur in the future, including but not limited to statements relating
to the Company's reserves and mineralized uranium materials, timing of
receipt of mining permits, production capacity of mining operations
planned for properties in South Texas and New Mexico, planned dates
for commencement of production at such properties, revenue, cash
generation and profits are forward-looking statements. Because they
are forward-looking, they should be evaluated in light of important
risk factors and uncertainties. These risk factors and uncertainties
include, but are not limited to, the spot price of uranium, weather
conditions, operating conditions at the Company's mining projects,
government regulation of the mining industry and the nuclear power
industry, the world-wide supply and demand of uranium, availability of
capital, timely receipt of mining and other permits fro regulatory
agents and other factors which are more fully described in the
Company's documents filed with the Securities and Exchange Commission.
Should one or more of these risks or uncertainties materialize, or
