Westwater Announces Significant Vanadium Discovery at Coosa Graphite Project

Recent Assays Show Vanadium Concentrations of up to 0.4% V2O5

Current Market Prices in Vanadium Reflect Greater Upside Potential
for Coosa

CENTENNIAL, Colo.–(BUSINESS WIRE)–$WWR #vanadium—Westwater Resources, Inc. (“Westwater,” or the “Company”) (Nasdaq:
WWR), an energy materials development company, is pleased to
announce the discovery of significant levels of vanadium concentrations
at several locales within the graphitic schists at the Company’s Coosa
Graphite Project, located in Coosa County, Alabama.

Christopher Jones, President and CEO of Westwater Resources, stated, “We
are delighted to confirm the discovery of vanadium on our existing
mineral leases in Alabama. The prospect of adding a vanadium credit to
our already robust economics at the Coosa Graphite Project appreciably
increases the value of our holdings. The Westwater team is designing an
exploration program to more fully define the extent of the vanadium
mineralization.”

“Westwater holds two large graphite development projects that now also
may contain significant levels of vanadium. Together with our lithium
properties and uranium holdings in the American West, and further to the
development to our Alabama-based graphite business, the potential income
we can generate from vanadium could translate to a higher valuation for
WWR in the future,” concluded Mr. Jones.

Recent assay results for numerous samples collected from the graphitic
schists in areas adjacent to the known graphite resource area of the
Coosa Project have shown concentrations values of up to 0.4% V2O5 (which
is equal to 8 pounds of V2O5 per short ton), as well as values ranging
up to 0.26% V2O5 in the graphite deposit area itself. Westwater believes
that these concentrations are significant and warrant integrated
evaluation of graphite-vanadium resources of the Coosa Graphite Project.
Vanadium pentoxide (V2O5) is the most common form traded and currently
sells for $33.10/lb. (98% V2O5 Flake, China as reported by www.vanadiumprice.com
on November 26, 2018). This current price represents a multi-year high,
with a rise of over 300% in the last 12 months.

The occurrences of elevated concentrations of vanadium in the Alabama
Graphite belt have been known since the 1940s, as documented by the
United States Bureau of Mines (USBM) Report of Investigations 4366
(December 1948). USBM documents anomalous vanadium results for samples
from the now inactive Fixico graphite mine, located on one of the
properties leased by Westwater and adjacent to the Coosa Graphite
Project and from Westwater’s Bama Mine in Chilton County, Alabama and
from the Dean Prospect, situated on properties controlled by Westwater.

What is Vanadium?

Vanadium is a lightweight metal used in the construction industry, in
high-strength steel alloys, and in large grid storage batteries.
According to the United States Geological Survey (USGS), about 80,000
metric tonnes of vanadium (as V) per year were consumed worldwide in
2017, approximately 80% of which was utilized by the steel industry,
where additions of the metal to conventional steel materials adds
strength and corrosion resistance. Importantly for Westwater, demand for
Vanadium Flow batteries is increasing as solar and wind power generators
seek to make their installations more reliable electricity providers.
Market research firm Roskill predicts that there will be a 45% increase
in demand for vanadium, mostly in China.

Currently, about 85% of all vanadium is produced in South Africa, China
and Russia. There is no significant production of vanadium currently in
the United States.

Westwater believes that the principal vanadium mineral at the Coosa
Graphite Project is roscoelite, a vanadium-bearing mica. This mineral
has been a significant component of vanadium ore production in the
United States, especially at the Rifle Creek and Placerville districts
of Colorado and the Uravan Mineral Belt region of western Colorado and
eastern Utah. Roscoelite ores were major sources of vanadium during
World War I and the period of the mid-1930s to 1945 as well as a
significant source of vanadium from the mines of the Uravan Mineral belt
during the late 1940s into the early 1980s.

About Westwater Resources

WWR is focused on developing energy-related materials. The Company’s
battery-materials projects include the Coosa Graphite Project — the most
advanced natural flake graphite project in the contiguous United States
— and the associated Coosa Graphite Mine located across 41,900 acres
(~17,000 hectares) in east-central Alabama. In addition, the Company
maintains lithium mineral properties in three prospective lithium brine
basins in Nevada and Utah. Westwater’s uranium projects are located in
Texas and New Mexico. In Texas, the Company has two licensed and
currently idled uranium processing facilities and approximately 11,000
acres (~4,400 hectares) of prospective in-situ recovery uranium
projects. In New Mexico, the Company controls mineral rights
encompassing approximately 188,700 acres (~76,000 hectares) in the
prolific Grants Mineral Belt, which is one of the largest concentrations
of sandstone-hosted uranium deposits in the world. Incorporated in 1977
as Uranium Resources, Inc., Westwater also owns an extensive uranium
information database of historic drill hole logs, assay certificates,
maps and technical reports for the western United States. For more

statements addressing events or developments that WWR expects or

additional analysis of the Coosa Graphite Project may result in
revisions to the findings of WWR’s initial optimization study; (b) the
