Namibia Rare Earths Successfully Advances Metallurgy of Rare Earth Deposit
Namibia Rare Earths (TSX: NRE, OTCQX: NMREF) reported on the completion of five more metallurgical
drill holes at Lofdal to provide larger volumes of material for metallurgical test work, and provided an update on the ongoing metallurgical test work in South Africa and Australia. This should increase options to
determine a flow sheet for producing a concentrate acceptable to a qualified joint venture partner. The additional five HQ drill holes for metallurgical test work reinforced the deposit’s geologic model for grade, geometry, and high level of heavy rare earth enrichment (HREE), and provided over 2,000 kg of representative
grade material to support the metallurgical test work. Since the completion of the resource estimate, for the
most part, resource expansion and exploration has taken a back seat to the metallurgical test work to complete a flow sheet to produce a heavy rare earth concentrate.
Namibia Rare Earths previously completed two HQ drill
“scissor holes” through the deposit for metallurgical purposes. These two samples somewhat bracketed the resource, confirming the consistency of the deposit and
validating the geologic model. These first two holes
were selected to secure both a high grade
(NLOFDH4084 at 1.50% TREO with 94.7% HREE) and
low grade (NLOFDH4085 at 0.26% TREO and 80.8%
HREE) sample to better understand and optimize a flow
sheet for a range of both high and lower grade portions
of the resource.

Initially, results from test work on the high grade sample following optimization were to be applied to the
lower grade sample with the intent to boost recoveries of the resource at the margin. This approach was
expected to both de-risk and improve the economics of the resource, potentially increasing the size of the
resource (by reducing the cut-off grade) and improve the grade of the concentrate. These activities fit
within the corporate objective of defining the quality of the resource and in determining the best flow sheet
for beneficiation, which is essential to increasing its attractiveness and value to a potential qualified technical partner.
The release provides an update on the metallurgical test work results on both the initial high and low grade
samples, and also on the significant improvements to recoveries to be expected from the upcoming bulk
sample runs as a result of detailed calibration tests on the x-ray transmission (“XRT”) sorting technology.
The XRT sorting was previously proposed as a means to improve beneficiation by initially removing waste
and thereby increasing grade to the mill. A number of approaches are being considered for a range of flow
sheets options to produce a concentrate including magnetic separation, a simple acid leach and flotation.
These approaches would be applied to both the high and low grade samples to develop options for an initial
flow sheet to produce a concentrate that would then be refined and optimized with further analysis made
possible using material from the more recent HQ drill holes.
The test work is being completed by Mintek in South Africa, and interestingly on the low grade sample,
Nambia Rare Earths reported work completed by Nagrom laboratories from Australia. This is significant
because Nagrom has experience in processing material from Northern Minerals Limited (ASX: NTU)
Brown Range (Wolverine deposit), which is most similar to Namibia Rare Earths’ deposit at Area 4 at Lofdal in Namibia. Both deposits are highly enriched with heavy rare earths contained in xenotime. This
should provide additional expertise to the initial metallurgical test work which will be applied to the material from the additional five HQ drill holes.
Summary of Additional Drill Results for Metallurgical Purposes
The additional five HQ drill holes totaled 708 meters over a 330 meter strike length in the center of the resource estimate. Of the five holes, two effectively twinned the initial “scissor holes,” with the remaining
three holes basically closing the gap. Like the initial scissor holes, the five holes were completed at a shallow angle entering the mineralized zone underneath from the footwall, proceeding downdip through the deposit, and exiting into the hanging wall. This produced approximately 2200 kg (roughly 2.5 tons) of additional mineralized material, now available for further metallurgical test work.

Management indicates that drilling on the five HQ drill holes intersected and exited the mineralized zone as
predicted. This provides further confidence that Namibia Rare Earths has completed a good geologic
model, which should provide optimism for predicting a continuation of the deposit at depth beyond that included in the resource, and demonstrates the consistency of the tabular nature of the mineralized zone. It is
also interesting to note that the grades and the level of heavy rare earth enrichment generally reflect that of
the initial resource estimate. (As the drill hole was completed for metallurgical purposes, the mineralized
interval is clearly not to be considered the true width of the deposit).

The initial resource, at a 0.3% cut-off, identified a 900,000 tonne Indicated resource of 0.62% TREO with
86% heavy rare earth enrichment and an Inferred resource of 750,000 tonnes at 0.56% TREO with 85%
heavy rare earth enrichment. At a lower grade cut-off of 0.1%, the resource increases to an Indicated resource 2.88 million tonnes at 0.32% TREO with 76% heavy enrichment, plus the Inferred resource increases to 3.28 million tonnes at 0.27% TREO with 75% heavy enrichment.

Improvements to Beneficiation by XRT Technology
Tomra Sorting Solutions GmbH of Germany
completed test work in 2012 and 2013 to determine the potential to presort run-of-mine
material to selectively separate waste using
XRT technology. Initial results reported in
April of 2013 on the material from the initial
two “scissor holes,” were positive, indicating
48 to 79% recovery with mass pulls of 55 to
75% to waste. This presented the opportunity
for reducing costs by eliminating waste on
site, thereby reducing the cut-off grade and
increasing the amount of material to be economically recovered. Following this success,
Tomra recommended a larger sample be obtained for additional test sorting, which resulted in the five new HQ drill holes.

Namibia Rare Earths believed that the sorting efficiency (recoveries) could be improved with detailed calibration tests assisted by estimating the percentage of total rare earth oxides (TREO) based on ppm yttrium
as determined by handheld XRF devices. The detailed calibration of the sorting equipment increased recoveries to 85 to 89% with a mass pull averaging 47% to waste. This is a significant improvement to the
first stage beneficiation, thereby improving the economics by eliminating waste rock early in the process
without losing too much mineralized material. It is expected that completing sorting test work on the additional material from the five subsequent HQ drill holes will be completed by Tomra in early December.
Following this test work, the sorted material will be available for Mintek and Nagrom to undergo additional
test work for other various approaches to produce a concentrate.
Discussion of Options for Concentrate Flow Chart
Metallurgical test work to date has been limited to producing concentrates from the two initial “scissor
holes.” In April of 2013, Namibia Rare Earths provided initial test results on the high grade sample drill
results with recovery by wet high intensity magnetic separators (WHIMS), which only demonstrated the
potential for magnetic separation to produce a concentrate. This produced good recoveries from Whole Ore
and unsorted Fines under 10mm, improving for Sorted Product over 10mm of 77.9%.

Mintek—WHIMS Grades and Recoveries from Lofdal High Grade Sample (NLOFDH4084) - April 2013
Source: Namibia Rare Earths
The recent release included the same WHIMS process with the introduction of scavenging and regrind circuits which increased recoveries for Sorted Product over 10mm to 89.5% and the concentrate grade increased to about 11.1% from about 10.2% with WHIMS alone. Namibia Rare Earths believes that a concentrate grade of 10% can be of interest to a qualified joint venture partner, so it would seem significant that
as outlined in the current press release the addition of a simple acid leach to Sorted Product magnetic concentrate has nearly doubled the concentrate grade to 19.8%, representing a recovery of 99% from the
WHIMS product.

The lower grade sample responded well to recovering xenotime, but the higher amounts of gangue mineralization including albite, calcite and hematite, and the fact that the lower grade sample is more oxidized
than the higher grade sample present challenges on recoveries. For example, WHIMs with a regrind and
scavenging circuit produced a concentrate from Sorted Product over 10mm with a grade of 1.65% and a
recovery of 55.1%. These first reported test results on the low grade material represent the baseline and it
will be interesting to see how the optimization of the WHIMS and addition of an acid leach might reduce
gangue minerals, or how other methods improve concentrate grade and recoveries.

Nagrom produced a concentrate from the same low grade material by floating WHIMS product, producing
similar grades but much better recoveries for Whole Ore and Sorted Product over 10mm. This is interesting
as one might expect the necessity for the flotation process with oxidized material. It is also interesting that
different approaches may have significantly different results based on variances of grade, degree of oxidation and the gangue mineralogy. Additional metallurgical test work will eventually lead to a flow sheet,
and will take these variances into account in the most economic manner. Clearly, the results from the initial
two “scissor holes” were early in the process and this update has demonstrated significant progress and understanding on the metallurgical characteristics of the deposit. The large amount of material now available
for test work should accelerate optimizing the flow sheet.
Analyst Visit to Namibia Rare Earths’ Lofdal Project in Namibia
We toured Namibia in September of 2013 with the Oregon Society of Economic Geologist Student Chapter,
visiting past and working mines, exploration projects and various geologic occurrences. Namibia Rare
Earths’ Lofdal project was included in the tour. Having previously visited Lofdal, we were most interested
in observing trends in the government and people of Namibia toward mining, foreigners and foreign investment, as well as to note any trends in Namibia toward mining in general.
The visit enhanced our opinion of the relative
high importance of mining to Namibia from
the perspective of taxation and employment.
Recognizing the increasing number of years
to bring a deposit to an active mine, we were
alarmed that all of the active mines visited on
the tour appeared nearing the end of the initial mine life and were stretching to push
back open pits or advancing lower grade and
less optimal tertiary deposits. This should
increase the importance to the government of
advancing projects to construction and production, as well as to commit to a predictable
taxation regime to attract foreign capital.

We were fortunate to have been guided by Dr. Roy
Miller, who is considered to be the “godfather” of Namibian Geology. His frankness was helpful to make systematic inquires as well as place observations in context.
We were concerned about rule of law and Namibia’s part
in a global progressive trend toward active government
overreach. It was interesting that while we were in Namibia, the courts upheld the assertion of farmers and
threw out what they viewed were excessive and potentially bankrupting tax increases on marginally productive
land. Also important were the independent critical opinions expressed in the press toward government tax assessors following this landmark reprimand by the courts.
This provided a refreshing view of both impartial courts
and independent press. Both of these, in our experience
and opinion, are important for rule of law important to
foreign investment. We assume this type of treatment
would be extended to the mining industry as well.

We were also quite interested in the attitude of people or government toward investment from China.
There appeared to be a distinct opinion, generally from a wide range of individuals, to the Chinese manner
of doing business of cutting corners or being less sensitive to building requirements, including Namibian
workers or local contractors. This was particularly important considering the largest project now under
construction is the Husab uranium mine. It will be important for Namibia to fully support and enable regulators to enforce regulations. It is interesting that while companies from “developed nations” may lack the
national financial clout of China, they are well versed in the important commitment toward community engagement and partnerships. This is a distinct advantage for “developed nations” should it be a priority for
the Namibian government.
Comments on the Rare Earth Sector of the Mining Industry
The prices of mining companies, including companies in the rare earth niche, and the prices of both light
and rare earths appear to have bottomed. Our investment thesis anticipated that this trend may allow for
the destruction of the field of weaker companies and projects. This would include projects with not only a
poor collection of attributes important to successfully develop a mine, but in the case with rare earth deposits, this would further include predominately light rare earth deposits or deposits with a patchwork of mineralization challenges. It would also appear that mining companies with excessive requirements for infrastructure or costly processing may have high financing requirements which are particularly unattractive to
investors.

It is also interesting to us that investors have no tolerance for assumptions in technical reports which appear
not to have been thoroughly vetted. While important for all types of mining projects, given the heightened
metallurgical requirements to cost effectively produce a rare earth concentrate, a consistent and thorough
metallurgical program remains an indispensible component of developing rare earth projects. Consequently, a complete and credible metallurgical program is essential to monetize the resource to both the investment community and to secure a qualified joint venture partner.
In our opinion, companies with the most attractive projects to develop are located in mining jurisdictions
friendly to mining with good infrastructure and modest capital costs to reduce financing risk. High concentration of heavy rare earths is essential, at grades or with the potential to concentrate and improve economics. Clearly, metallurgy is important. We see Namibia Rare Earths’ Lofdal project and Northern Minerals
Limited Wolverine deposit having the greatest potential given their level of heavy rare earths and important
to their being contained in xenotime with an existing commercially proven pathway to production. Tasman
Metals Ltd. (NYSE MKT: TAS) and Matamec Explorations, Inc. (TSX – V: MAT) also have heavies but
are contained within eudyalite and have successfully graduated from the lab to a critical pilot plant stage.
Ucore Rare Metals Inc. TSX – V: UCU) also has a promising solid phase extraction in the lab, but this also
has not been proven commercially. Should unproven technologies fail to advance as scheduled, it is apparent that the projects in xenotime mineralization have the greatest potential to outpace competitors. In addition, depending on the unfolding information on heavies in China, it will be interesting to see the impact on
heavy rare earth prices, with few projects in the rest of the world moving into production as scheduled.
Concluding Comments
We continue to believe that ongoing demand for heavy rare earths, with limitations on production and the
addition of the containment of illegal mining in China, should lead to higher prices for heavy rare earths. It
is apparent by most any forecast that increases in supply are suspect to meet demands for heavy rare earths
outside China (and in the case of dysprosium, within China itself). In our opinion, of the hundreds of rare
earth projects, Namibia Rare Earths’ Lofdal project remains one of only a handful of potential projects capable of success.
The recent metallurgical results provide great transparency for investors as to the numbers of considerations
and the importance of a consistent and well understood deposit. One of the most important issues with failures inherent in feasibility studies, is the inability to move from lab to the mill and produce product as predicted. The results demonstrate multiple options for robust recovery, as seen in work completed on the
higher grade sample. It also demonstrates the challenges of improving the economics of lower grade portions of the deposit. In the case of the low grade sample, included are not only lower grades, but it is also
complicated by higher levels of oxidation and the inclusion of gangue mineralization. Management should
be complimented for the foresight to include the lower grade sample early in the process and its transparency in reporting results. Clearly, this will remain an area of focus, as much as extending progress for the
high grade sample, to better understand the deposit in completion of a reliable flow chart.

Namibia Rare Earths is in an excellent position to build upon metallurgical test work to date. Work continues on the material secured from the initial “scissor holes.” Having provided an additional 2,200 kg’s to the
labs for additional test work should provide a significant opportunity to increase the value of the resource at
relatively little cost. Management should also be complimented for securing a large sample to the labs,
which exceptionally enhances the opportunity for the labs to produce data that may optimize the resource.
As there is proven technology to recover heavy rare earths from xenotime, there is less risk and possibly
time to production than competing projects requiring new processes. While there is clearly potential to expand the resource by additional drilling at depth, following through on metallurgical test work is the most
direct path to both attract a qualified joint venture partner and monetize Area 4 of Lofdal.
