RiskMetrics Recommends Pala’s Slate for Rockwell Board

TORONTO - Pala Investments Holdings Limited (”Pala”) welcomes the recommendation published by RiskMetrics today with respect to Pala’s proposed changes to the Board of Directors of Rockwell Diamonds Inc. (”Rockwell”, TSX: RDI, JSE : RDI, OTCBB: RDIAF).

The independent voting advisory service RiskMetrics Group, a leading provider of risk management and corporate governance products and services, has issued its voting recommendations for the upcoming special meeting of Rockwell shareholders to be held next week. RiskMetrics fully supports the election of the independent directors proposed in Pala’s Proxy Circular.

“The RiskMetrics recommendation highlights the quality of the independent board proposed by Pala,” said Colin Murray, Chief Operations Officer of Pala Investments AG, advisor to Pala. “The real issue facing Rockwell is the current lack of leadership. The shareholders meeting to take place next week provides shareholders with the opportunity to exercise their rights and do something about the situation.”

Additional information on these matters and details about the upcoming Rockwell shareholders’ meeting can be found in the Proxy Circular mailed to shareholders on May 20, 2009, and available on www.sedar.com.
