Westwater Resources Announces Strong Vanadium Results from Comprehensive Sampling at the Coosa, Alabama Graphite Project

Will Immediately Commence Development of Vanadium Exploration Plan

CENTENNIAL, Colo.–(BUSINESS WIRE)–lt;a href=”https://twitter.com/search?q=%24WWR&src=ctag” target=”_blank”gt;$WWRlt;/agt; lt;a href=”https://twitter.com/hashtag/vanadium?src=hash” target=”_blank”gt;#vanadiumlt;/agt;–Westwater Resources, Inc. (“Westwater,” or the “Company”) (Nasdaq:
WWR), an energy materials development company, is pleased to
announce the receipt of positive analytical results (assays) for
vanadium mineralization (as V2O5 – vanadium pentoxide) at our Coosa,
Alabama Graphite Project. The recently received assay data was derived
from more than 1,900 samples selected from 35 core drill holes and 16
trenches, which were previously sampled and assayed for only graphite as
a part of defining the graphite resource in 2015 Preliminary Economic
Assessment (PEA) investigation. Sample locations were selected within
the Coosa PEA resource area as well as vanadium target areas identified
by the 2018 sampling program as presented in our news release of
November 29, 2018, in which the Company announced the identification of
appreciable levels of vanadium mineralization at Coosa. Positive values
for vanadium are widespread and extend considerably beyond the graphite
resource defined in the PEA from 2015. This sampling program represents
the next stage of exploration of the vanadium mineralization at the
Coosa Project.

Four-hundred-forty-one of the 1,923 samples collected for geochemical
analysis returned vanadium grades greater than 0.15 percent V2O5 (3
pounds of V2O5 per short ton). Several of the assays exceeded 0.40% V2O5
(8 pounds of V2O5 per short ton). Individual sample intervals ranged
from 1.52 feet to 5.0 feet in length each. Numerous continuously
mineralized zones (at grades of 0.15% V2O5 or more) have apparent
thicknesses in drill holes ranging from 2 feet to 72 feet and apparent
widths in trenches ranging up to 50 feet. Limited QEMSCAN and EDX
analysis by Actlabs in Ontario, Canada indicated that the vanadium
occurs in several mineral phases including roscoelite, low V biotite and
low V Fe‐hydroxides. Roscoelite is recognized visually in the field by
the presence of some bright green minerals and has been a historical
source of vanadium from mines in western Colorado and eastern Utah, as
well as other localities from the early 1900s to the early 1980s.

These analytical results demonstrate the wide-spread distribution of
vanadium mineralization throughout the central portion of the Company’s
mineral holdings within the Coosa Project. Key target areas displaying
strong and continuous vanadium mineralization include the PEA graphite
resource area, known as the Grid deposit area, the eastern margin of the
Grid deposit area, the northeastern extension of the Grid deposit, and a
parallel belt of favorable quartz-graphite schist (QGS) and
quartz-muscovite-biotite graphite schist (QMBGS) that includes the
former Fixico graphite mine, the Roscoe Ridge prospect and the Holy
Schist target. Data indicates that zones of strong vanadium
mineralization are clearly accompanied by strong graphite mineralization.

The wide-spread distribution of highly anomalous vanadium
mineralization, commonly in association with strong graphite
mineralization, points to the need for comprehensive follow-up drilling
and trenching to more fully define the ultimate distribution and
intensity (grade) of the graphite and vanadium resources of the Coosa
Project. Planning is underway for additional core drilling and surface
trenching of individual target areas and extensions of known mineralized
zones. Additionally, Westwater will initiate a program to evaluate and
assess various processing options to economically recover vanadium as a
byproduct to graphite.

Christopher M. Jones, President and Chief Executive Officer, commented,
“We are thrilled to have received laboratory verification of the
presence of wide-spread vanadium mineralization at our Coosa property,
with some positive values beyond the original resource defined in the
2015 PEA. Vanadium is a highly versatile mineral, with a strong demand
profile throughout the world – particularly in the steel industry where
80% of the supply is used.

“As is the case with our graphite, lithium and uranium assets, vanadium
is also considered one of the critical resources listed by the US
Geological Survey. However, there is no significant production of
vanadium, or mining operations in the U.S., which is why vanadium is
generally imported. Approximately 85% of vanadium production originates
in South Africa, China and Russia – with China being the leader at
nearly 40% of world-wide production.

“We intend on immediately developing a vanadium exploration program,
with the goal of optimizing this high-quality opportunity prudently and
to our maximum benefit. We expect to have this plan completed in coming
weeks,” concluded Mr. Jones.

Quality Control/Quality Assurance and Analytical Laboratory

Geochemical determinations of the vanadium content of the samples were
performed by American Assay Laboratories, of Sparks, Nevada USA, a
long-standing, independent, third-party commercial assay laboratory,
utilizing a five acid digestion and inductively coupled plasma mass
spectroscopy (ICP) as its analytical method. American Assay holds an
ISO/IEC 17025:2005 Accreditation. Quality control and quality assurance
included the inclusion of “blank” samples (barren of vanadium) and
duplicate samples into the sample submissions by Westwater personnel.
“Control samples”, comprised of geochemical standards, “blanks”, and
laboratory duplicates totaling 477 samples were employed by American
Assay to ensure QA/QC. Duplicate samples were submitted to an
independent third-party laboratory.

About Westwater Resources

Westwater 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 deposit 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 information, visit www.westwaterresources.net.
