CUSIP: 39141Y 10 3

SASKATOON, March 18, 2013 /PRNewswire/ – Great Western Minerals Group Ltd.
(“GWMG” or the “Company”, TSX:V – GWG) today announced positive results
from a Preliminary Economic Assessment (“PEA”) of the Company’s
Steenkampskraal rare earth element (“REE”) project that indicates
strong potential for GWMG’s integrated business model.

Project highlights (all amounts in this news release are in $ Cdn. unless otherwise

  • $555 Million after-tax net present value (“NPV”) applying a 10% discount
    rate and a 28% South African corporate tax rate

  • 66% after-tax internal rate of return (“IRR”)
  • 4.3 year estimated Project payback period, on an after-tax basis, from
    start of underground mining production.
  • 11 year potential life of mine

GWMG President and Chief Executive Officer Marc LeVier said, “The PEA
conducted on the Steenkampskraal project confirms our internal
projections of a high grade and excellent distribution of the critical
rare earth elements. The impressive, high-grade nature of
Steenkampskraal translates into lower tonnages for processing, which in
turn, results in low capital cost requirements relative to other REE
projects. The work undertaken on the project to date and the
accelerated metallurgical testing program is intended to enable GWMG to
advance the project rapidly. This ‘early mover’ status, combined with
GWMG’s existing alloy manufacturing capacity, positions GWMG very

Financial and Operating Highlights

The PEA is preliminary in nature and includes an economic assessment of
Indicated Mineral Resources and Inferred Mineral Resources (terms which
have the meanings ascribed to them by the Canadian Institute of Mining,
Metallurgy and Petroleum, CIM Definition Standards on Mineral Resources
and Mineral Reserves).

The Inferred Mineral Resources are quantified based on the potential
viability of the Resource Estimate of the Steenkampskraal project and
are considered too speculative geologically to have the economic
considerations applied to them that would enable them to be categorized
as Mineral Reserves (CIM Definition, Standards on Mineral Resources and
Mineral Reserves).

Mineral Resources that are not Mineral Reserves do not have demonstrated
economic viability and there is no certainty that the results of the
preliminary economic assessment will be realized.

The PEA contains a sensitivity analysis which demonstrates that the
Project valuation is most sensitive to changes in REO prices.  The
Project valuation is least sensitive to changes in capital

REO Pricing

GWMG has selected the midpoint of the Roskill 2015 forecast of rare
earth prices for the PEA. The forecast prices are the averages of the
high and low ranges to a midpoint.

Pricing Sensitivity


Production of mixed RECl (concentration and hydrometallurgical stages)
is projected to commence within 24 months of the completion of required
Project financing, at a design capacity of approximately 5,000 tonnes
per year of contained REOs.

Production of separated REOs is projected to commence within 12 months
of the commencement of RECl production at a design capacity of
approximately 5,000 tonnes per year of separated REOs per annum.

Resource Estimate Highlights

The PEA is based on the Resource Estimate for the Project, as filed on
SEDAR on March 7, 2013, which reports 278,000 tonnes of Inferred
Mineral Resources at an average grade of 15.2% TREO and 176,000 tonnes
of Indicated Mineral Resources at an average grade of 18.2% TREO, each
using a 1% TREO cut-off grade.  The Resource Estimate includes the
historic mine area (the “Monazite Mine Area”), and the exploration
areas to the east and west of the past producing Monazite Mine Area
(the “EXP Area”) as well as the historic upper tailings and lower

Steenkampskraal Project Overview

The Project is comprised of three activities, as part of GWMG’s overall
five-part integrated business model, namely (i) the underground mine
and future reprocessing of tailings; (ii) the RECl Plant that produces
mixed RECl; and (iii) the solvent extraction separation plant (the “RE
Separation Plant”) that produces separated REOs.  Thereafter, GWMG’s
integrated business model includes installation of metal making
capacity and expansion of current alloy production capacity at Less
Common Metals Limited (“LCM”), GWMG’s subsidiary located in the United

The Project is based on a high grade / narrow vein underground mine,
which was successfully operated by Anglo American to recover thorium
between 1952 and 1963.  GWMG’s proposed mining method, ventilation and
overall operations consist of common and conventional processes and
procedures, of which there are numerous analogues throughout South
.  The Project is estimated to hoist approximately 165 tonnes per
day of ROM material.

In addition, and very importantly to the directors and management of
GWMG, the Project has been designed to, concurrently with production,
rehabilitate historical environmental impacts caused by former

Steenkampskraal Monazite Mine (Pty) Ltd (“SMM”), a subsidiary of GWMG,
was awarded a New Order Mining Right (the “Mining Right”) permitting
mining operations in an area of approximately 474 hectares for a
20-year period commencing June 2, 2010.  SMM also holds a Certificate
of Registration (“COR”) with the South African nuclear regulators,
which authorizes processing of radioactive material with respect to the
Steenkampskraal site, including the long term storage of the thorium
by-products that will be produced.  The COR also allows SMM to apply
for and obtain specific approvals for proposed methods of storage of

Through its subsidiary Rare Earth Extraction Co. Limited, GWMG has
embarked on a mine refurbishment program which includes establishment
of surface infrastructure, rehabilitation of the existing shaft,
opening underground access and main haulages, the re-survey of existing
underground workings, and the installation of temporary ventilation to
facilitate preliminary activities. Furthermore, the general
refurbishment has permitted extensive in-fill and exploratory diamond
drilling on surface, as well as several campaigns of underground
sampling for assay and metallurgical testwork, and geotechnical
investigations.  These undertakings and investigations have facilitated
the Resource Estimate and the preparation of the PEA. In the interest
of health and safety, and to ensure efficient operations, a program of
re-vamping the raises, drives, cross-cuts and re-equipping of services
such as compressed air lines, water lines, power supply, rails and
ground handling box fronts has commenced.

Production Estimate

Mining, RECl and RE Separation Summary

The underground host rock demonstrates notable competence as even after
50 years the majority of the excavated and remaining old mining area
shows no visible signs of stress or instability.

The underground Monazite Mine Area will use a combination of
conventional and shrinkage stoping for flat and steeply dipping
sections of the mine, respectively.  Conventional jack leg drilling and
blasting will be used, with cleaning being done by winches scraping the
broken rock down the raises to main haulages.

The underground EXP Area is immediately adjacent to the underground
Monazite Mine Area, both contained within the New Order Mining Right. 
Access to the EXP Area is planned to be through a new separate shaft
for personnel and materials. This shaft will also be used for the
intake ventilation to the workings and there will be a separate exhaust
return air raise.  For the purpose of the PEA, it has been assumed that
the EXP Area mine layout will be similar to the existing Monazite Mine

The ultimate objective of the RECl Plant is to extract the REE’s from
the hoisted ROM material and convert them to a purified mixed RECl.
This will be performed via comminution processes, followed by
concentration, and then several stages of leaching to remove

The RECl Plant is being designed to treat 70,000 tonnes per annum, or
approximately 192 tonnes per day, of hoisted ROM feedstock, which is
estimated to be sufficient to produce RECl containing up to 6,000
tonnes of REOs per annum. The ROM will be stockpiled on surface to be
conveyed to the RECl Plant.  Preparation of ROM will include primary
and secondary crushing followed by ball milling. The milled material
will then be floated to remove copper and iron sulphides, followed by a
monazite float to concentrate the REE-containing monazite. This will be
cracked and followed by water and acid leaching to remove impurities
and convert the REEs to a mixed RECl. Flotation tails and precipitated
impurities will be stockpiled under controlled conditions pending
re-use or recycle. The mixed RECl will be hauled to the RE Separation
Plant at Vredendal in the Western Cape of South Africa, located
approximately 100 kilometres from the Steenkampskraal mine site. 

There exists the potential to produce an alternative product in the form
of a RE carbonate from the RECl Plant, subject to process development
and proof of economic feasibility.  Operations at the Steenkampskraal
site are designed to remediate historical environmental impacts from
previous operators.

The mixed RECl will then be separated and converted into individual REOs
using a series of solvent extraction steps. Metals from the purified
solutions will subsequently be precipitated and calcined to convert to
REOs. No waste products will be stored at the RE Separation Plant.

Certain individual REOs (mainly those used in magnet alloys) will be
shipped to and utilized by LCM for further processing into metals and
alloys for its customers, while the balance of the REOs produced will
be sold into the spot market.  This comparatively short-term spot
market approach is the industry norm. However, GWMG is investigating
the potential for off-take arrangements.

Human Resources Summary

The Company’s project management team will deal with an EPCM contractor
who will manage all contractors during the planning, construction and
operations phases of the Steenkampskraal operation. Led by the Project
Director, the team will include a cross-section of experience and
skills to ensure that appropriate expertise is available for
comprehensive review of all areas of the mine, RECl Plant and RE
Separation Plant.

It is anticipated that approximately 450 employees will be required
throughout the operation including the mining, chloride production and
separation components.  It is also anticipated that the Company will
engage in a significant level of staff training in order to ensure that
sufficient multi-skilling and cross-training are achieved in order to
minimize staffing levels.

Mineral Processing and Metallurgical Testing

Various mineral processing and metallurgical investigations have been
undertaken on samples from the Project, including test work by SGS
South Africa (Pty) Ltd.  The current testing program consists of
accelerated parallel testing at Mintek (South Africa) in respect of
optimization of flotation and hydrometallurgical leaching tests, as
well as by the Saskatchewan Research Council.  Conceptually, processing
of the monazite-rich concentrate will consist of two basic components.
Beneficiation, which produces a mineral concentrate and consists of
crushing, milling, and concentration technology such as gravity,
magnetic, and flotation techniques and leaching which takes the mineral
concentrates and produces a liquid chloride solution of mixed RECl.

The mixed RECl Plant will be constructed at the Steenkampskraal mine
site, where thorium will be separated from the concentrate to meet the
required specifications for the RE Separation Plant and to meet
regulations to allow shipment.

Design work for the mine and processing plants commenced under the
guidance of DRA Mineral Projects of South Africa (“DRA”).  DRA has an
excellent track record of utilizing world class standards in its design
work and is well qualified for the Project.

The monazite concentrate has been successfully tested to create a mixed
RE chloride solution, with the potential to produce an alternative
product, namely  an RE carbonate, currently being evaluated as an
opportunity to advance cash flow. The testwork continues to further
optimize process conditions and reagent consumptions for all stages of

Environmental Plan

The Steenkampskraal Project is being advanced under an existing and
valid Environmental Management Programme and Environmental Impact
Assessment that has been reviewed and accepted by the applicable
governing bodies of the Government of South Africa.  As changes in
Company plans or government regulations arise, the Company will take
all necessary steps to ensure it remains fully compliant with current
regulatory requirements.

On site, secure, fortified, long term storage will be authorized under
the Company’s COR, and consequently there will be no requirement for
off-site transportation of any radioactive materials. The final storage
procedure is to be assessed and confirmed according to National Nuclear
Regulator and international standards.

Options under Evaluation

Although the PEA focuses on the Steenkampskraal Project, the Company is
convinced it is uniquely positioned within the rare earth sector due
its ownership of LCM. The alloy manufacturing capability of LCM
provides the Company with ready access to international markets.  The
Company’s fully integrated business model and the long established
business relationships earned by LCM over a 21 year time frame, provide
a high level of competitive advantage.

In the course of evaluating its strategic options for the development of
rare earth separation capacity, the Company has focused on the
construction of the RE Separation Plant at Vredendal in the Western
Cape of South Africa, located approximately 100 kilometres from the
Steenkampskraal mine site.  In addition to constructing the RE
Separation Plant, and as a means to achieve revenue in the shortest
timeframe, the Company continues to evaluate the potential for entering
into a tolling arrangement whereby the mixed rare earth product
produced at the RECl Plant could be separated through the facilities of
a third party. This strategy, if followed and successful, would
significantly reduce initial capital requirements for the Project,
thereby positively impacting the Net Present Value.

There also exists the potential to produce an alternative product in the
form of a RE carbonate from the RECl Plant, subject to further
examination of chemical and economic feasibility.

The Company recognizes the funding requirements to deliver the project
and the primary objective of generating cash flow at the earliest date
possible, and is aggressively pursuing its options with the following

  • Reductions in capital requirements through the additional studies
    currently underway as recommended by the Company’s advisors and
    building to the standard of “fit for purpose” and

  • Investigating the potential for an off-take arrangement leveraging off
    of our existing knowledge of downstream customers and the interest in
    securing a long term supply of metals.

The PEA is based on a Mineral Resource estimate and Technical Report
(the “Resource Estimate”) prepared in accordance with National
Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”), as announced and filed on SEDAR on March 7, 2013.  The
