Forward looking statements

This presentation includes certain statements and other information that may be deemed "forward-looking".

Other than statements of historical fact all statements in this presentation that address future production,

resource potential, exploration drilling, exploitation activities and events or developments that the Company

expects are forward-looking statements.

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

market prices, exploitation and exploration successes, availability of capital and financing, and general economic,

market or business conditions.

Forward-looking statements are also based upon management’s assumptions regarding the Company’s future

operations growth prospects, and conditions affecting the mining industry generally. Investors are cautioned that

any such statements are not guarantees of future performance and that actual results or developments may

differ materially from those projected in the forward-looking statements.

For more 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 atwww.sedar.com.

Except to the extent required by law, the Company is under no obligations to update any forward looking

statements contained in this presentation.

Holpan and Klipdam - Operational update

Evaluating options to extend Holpan’s life of mine

• Five years of Rooikoppie type II reserves remaining at Holpan

• Lower volume mining requiring redesign of process; or

• Contract mining option

Klipdam is performing to expectation

• Overcame impact of flooding

• Evaluating similar options to extend life of mine by excavating

Rooikoppie resources and exploration potential

Impact of January 2011 flooding rapidly overcome

Holpan and Klipdam mine operations

• 342mm (75% of annual average) in six-day period with >100mm on 23 January

• Five days of production lost

• Minor infrastructure damage at mines and mining roadway infrastructure remains intact

• Repairs and recovery operations initiated immediately and operations resumed on 25 January

• Damp gravels affected production for several more days until they dried out fully

Saxendrift mine operations

• Sporadic rainfall of 189mm (>50% of average annual rainfall) in two weeks to 23 January

• Negative impact on production volumes with loss of three mining days

• Production at full capacity quickly resumed

Impact at Tirisano mine construction

• Slight construction delays and completion date of March 2011 unaffected

• Sufficient drainage systems planned and commissioned into initial layouts to prevent flooding
