Certain information set out in this presentation constitutes forward-looking information. Forward-looking statements (often, but not always, identified by the use of words
such as “expect”, “may”, “could”, “anticipate” or “will” and similar expressions) may describe expectations, opinions or guidance that are not statements of fact and which
may be based upon information provided by third parties. Forward-looking statements are based upon the opinions, expectations and estimates of management of
GWMG as at the date the statements are made and are subject to a variety of known and unknown risks and uncertainties and other factors that could cause actual
events or outcomes to differ materially from those anticipated or implied by such forward-looking statements. Those factors include, but are not limited to, the assumptions
and estimates in the preliminary economic assessment of the Steenkampskraal project proving to be accurate over time; the construction, commissioning and operation of
the proposed monazite processing facility and separation facility within estimated parameters; mine refurbishment activities; reliance on third parties to meet projected
timelines and commencement of production at Steenkampskraal; risks related to the receipt of all required approvals including those relating to the commencement of
production at the Steenkampskraal mine, delays in obtaining permits, licenses and operating authorities in South Africa and China, environmental matters, water and land
use risks; risks associated with the industry in general, commodity prices and exchange rate changes, operational risks associated with exploration, development and
production operations, delays or changes in plans, including those estimated in the preliminary economic assessment of the Steenkampskraal project; risks associated
with the uncertainty of resource estimates; health and safety risks; uncertainty of estimates and projections of production, costs and expenses; risks that future
Steenkampskraal and region exploration results may not meet exploration or corporate objectives; the adequacy of the Company’s financial resources and the availability
of additional cash from operations or from financing on reasonable terms or at all; political risks inherent in South Africa and China; risks associated with the relationship
between GWMG and/or its subsidiaries and communities and governments in South Africa, radioactivity and related issues, dependence on one mineral project; loss of,
and the inability to attract, key personnel; the factors discussed in the Company’s public disclosure record; and other factors that could cause actions, events or results not
to be as anticipated. In light of the risks and uncertainties associated with forward-looking statements, readers are cautioned not to place undue reliance upon forward-
looking information. Although GWMG believes that the expectations reflected in the forward-looking statements set out in this presentation or incorporated herein by
reference are reasonable, it can give no assurance that such expectations will prove to have been correct. Except as required by law, GWMG does not assume any
obligation to update forward looking statements as set out in this presentation. The forward-looking statements of GWMG contained in this Presentation, or incorporated
herein by reference, are expressly qualified, in their entirety, by this cautionary statement and the risk factors contained in GWMG’s Annual Information Form available at
www.sedar.com.
Cautionary Note For US Investors Concerning Estimates of Indicated and Inferred Resources
This presentation uses the terms “Indicated” and “Inferred” resources. United States investors are advised that while such terms are recognized and required by Canadian
regulations, the United States Securities and Exchange Commission does not recognize them. “Inferred” mineral resources have a great amount of uncertainty as to their
existence, and as to their economic and legal feasibility. It cannot be assumed that all or any part of an Inferred mineral resource will ever be upgraded to a higher category.
Under Canadian rules, estimates of Inferred mineral resources may not form the basis of feasibility or other economic studies except in limited circumstances and with specific
notification to the reader. United States investors are cautioned not to assume that all or any part of any mineral resources will ever be converted into mineral Reserves (as
defined under NI 43-101). United States investors are also cautioned not to assume that all or any part of an Inferred mineral resource exists, or is economically or legally
mineable.

(3) Brent C. Jellicoe, B.Sc. (Hon.), P.Geo., Director of International Exploration for GWMG, is the Qualified Person
(as defined in NI 43-101) responsible for supervising the preparation of the technical content of this
presentation.
(4) For a complete description of the mineral resource estimate and technical report (the “Resource
Estimate”), please refer to the Resource Estimate, as filed on SEDAR on March 7, 2013, at www.sedar.com
(5) The PEA is preliminary in nature and includes Inferred mineral resources (as defined in NI 43-101) that are
considered too speculative geologically to have the economic considerations applied to them that would enable them
to be categorized as mineral reserves (as defined in NI 43-101), and there is no certainty that the preliminary
economic assessment will be realized.
(6) For the Resource Estimate, “tonnes” and “grades” were rounded to 3 significant figures. Apparent errors in the totals
may occur due to rounding.
(7) “LREO” means lanthanum (La2O3), cerium (CeO2), praseodymium (Pr6O11), neodymium (Nd2O3) and samarium
(Sm2O3). “HREO” means europium (Eu2O3), gadolinium (Gd2O3), terbium (Tb4O7), dysprosium (Dy2O3), holmium
(Ho2O3), thulium (Tm2O3), ytterbium (Yb2O3) lutetium (Lu2O3) and yttrium (Y2O3). “TREO” includes yttrium.
