FORWARD LOOKING STATEMENTS Except for statements of historical fact, this presentation release contains certain "forward-looking information" within the meaning of applicable securities law. Forward-

looking information is frequently characterized by words such as "plan", "expect", "project", "intend", "believe", "anticipate", "estimate" and other similar words, or

statements that certain events or conditions "may" or "will" occur. Although the Company believes the expectations expressed in such forward-looking statements are

based on reasonable assumptions, such statements are not guarantees of future performance and actual results or developments may differ materially from those in the

forward-looking statements.

Factors that could cause actual results to differ materially from those in forward-looking statements include uncertainties and costs related to exploration and

development activities, such as those related to determining whether mineral resources exist on a property; uncertainties related to expected production rates, timing of

production and cash and total costs of production and milling; uncertainties related to the ability to obtain necessary licenses, permits, electricity, surface rights and title

for development projects; operating and technical difficulties in connection with mining development activities; uncertainties related to the accuracy of our mineral

resource estimates and our estimates of future production and future cash and total costs of production and diminishing quantities or grades if mineral resources;

uncertainties related to unexpected judicial or regulatory procedures or changes in, and the effects of, the laws, regulations and government policies affecting our mining

operations; changes in general economic conditions, the financial markets and the demand and market price for mineral commodities such and diesel fuel, steel,

concrete, electricity, and other forms of energy, mining equipment, and fluctuations in exchange rates, particularly with respect to the value of the US dollar, Canadian

dollar and South African Rand; changes in accounting policies and methods that we use to report our financial condition, including uncertainties associated with critical

accounting assumptions and estimates; environmental issues and liabilities associated with mining and processing; geopolitical uncertainty and political and economic

instability in countries in which we operate; and labour strikes, work stoppages, or other interruptions to, or difficulties in, the employment of labour in markets in which we

operate our mines, or environmental hazards, industrial accidents or other events or occurrences, including third party interference that interrupt operation of our mines or

development projects.

For further information on Rockwell, Investors should review Rockwell's annual Form 20-F filing with the United States Securities and Exchange Commission

www.sec.com and the Company's home jurisdiction filings that are available at www.sedar.com.

This presentation also uses the terms 'indicated resources' and 'inferred resources'. Rockwell Diamonds Inc. advises investors that although these terms are recognized

and required by Canadian regulations (under National Instrument 43-101 Standards of Disclosure for Mineral Projects), the U.S. Securities and Exchange Commission

does not recognize them. Investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into reserves. In

addition, 'inferred resources' have a great amount of uncertainty as to their existence, and 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 pre-feasibility studies, or economic studies except for Preliminary Assessment as defined under 43-101. Investors are cautioned not to assume that part or all of an

inferred resource exists, or is economically or legally mineable.

The securities of Rockwell being offered have not been, nor will be, registered under the U.S. Securities Act and may not be offered or sold within the United States or to,

or for the account or benefit of, U.S. persons absent U.S. registration or an applicable exemption from U.S. registration requirements. This information does not constitute

an offer or sale of securities in the United States. Prior to making any investment decision, investors should consult a professional advisor.
