Disclosure

The Toronto Stock Exchange and the NYSE American have not reviewed and do not

accept responsibility for the accuracy or adequacy of this news release, which has been

prepared by management.

This press release contains forward-looking information within the meaning of Canadian

securities laws and forward-looking statements within the meaning of U.S. securities laws

(collectively “forward-looking statements”), including statements regarding the potential

transfer of an interest in, and right of first refusal relating to, the Waterberg Project from

JOGMEC to Hanwa; future drilling; the projections in the Waterberg pre-feasibility study;

the completion and contents of the Waterberg DFS; the potential exercise of Implats’

option; and the potential development and cost structure of, and production from, the

Waterberg Project. Forward-looking statements are typically identified by words such as:

believe, expect, anticipate, intend, estimate, plans, postulate and similar expressions, or

are those, which, by their nature, refer to future events. All statements th at are not

statements of historical fact are forward -looking statements. Statements of mineral

resources and mineral reserves also constitute forward-looking statements to the extent

they represent estimates of mineralization that will be encountered on a property and/or

estimates regarding future costs, revenues and other matters . Although the Company

believes any forward-looking statements in this press release are reasonable, it can give

no assurance that the expectations and assumptions in such statements will prove to be

correct. The Company cautions investors that any forward -looking statements by the

Company are not guarantees of future results or performance , and that actual results

may differ materially from those in forward -looking statements as a result of various

factors, including that the completion of the described transfer from JOGMEC to Hanwa

is uncertain, and the risk factors described in the Company’s Form 20-F annual report,

annual information form and other filings with the Securities and Exchange Commission

(“SEC”) and Canadian securities regulators, which may be viewed at www.sec.gov and

www.sedar.com, respectively.

Estimates of mineralization and other technical information included or referenced in this

press release have been prepar ed in accordance with NI 43 -101. The definitions of

proven and probable reserves used in NI 43 -101 differ from the definitions in SEC

Industry Guide 7. Under SEC Industry Guide 7 standards, a "final" or "bankable"

feasibility study is required to report reserves, the three-year historical average price is

used in any reserve or cash flow analysis to designate reserves and the primary

environmental analysis or report must be filed with the appropriate governmental

authority. As a result, the reserves reported by the Company in accordance with NI 43-

101 may not qualify as "reserves" under SEC standards. In addition, the terms "mineral

resource", "measured mineral resource", "indicated mineral resource" and "inferred

mineral resource" are defined in and req uired to be disclosed by NI 43 -101; however,

these terms are not defined terms under SEC Industry Guide 7 and normally are not

permitted to be used in reports and registration statements filed with the SEC. Mineral

resources that are not mineral reserves do not have demonstrated economic viability.

Investors are cautioned not to assume that any part or all of the mineral deposits in

these categories will ever be converted into reserves. "Inferred mineral resources" have

a great amount of uncertainty as to their existence, and great uncertainty 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 securities

laws, estimates of inferred mineral resources may not form the basis of feasibility or pre-

feasibility studies, except in rare cases. Additionally, disclosure of "contained ounces" in

a resource is permitted disclo sure under Canadian securities laws; however, the SEC

normally only permits issuers to report mineralization that does not constitute "reserves"

by SEC standards as in place tonnage and grade without reference to unit measurements.

Accordingly, information contained or referenced in this press release or the documents

referred to in this press release containing descriptions of the Company's mineral

deposits may not be comparable to similar information made public by U.S. companies

subject to the reporting and disclosure requirements of United States federal securities

laws and the rules and regulations thereunder.
