Completion of Jasper Mine Acquisition Increases Rockwell's Optionality in Middle Orange River Region

VANCOUVER, British Columbia, March 20, 2013 /PRNewswire/ --

Rockwell Diamonds Inc. ("Rockwell" or the "Company") (TSX: RDI; JSE: RDI) is pleased to announce that it has, consequent upon the Old Order Mining Rights held by Jasper having been converted into New Order Mining Rights,^[1] completed its acquisition of the Jasper Mine by settling the purchase consideration through the issue of shares.

The agreement to acquire the Jasper Mine project, which is contiguous to Rockwell's Saxendrift Mine, formed part of the transaction to unwind the Company's Black Economic Empowerment ("BEE") partnership with Africa Vanguard Resources ("AVR") (as announced on March 19, 2012):

• Jasper acquisition: Rockwell's application for the New Order Mining Right at Jasper has recently been approved, triggering the payment by the Company of R2.0 million (C$221,484) in Rockwell shares listed on the JSE Limited, to the Jasper shareholders. A total of 533,332 shares were issued at R3.75 (C$0.41) per share, which represents the 5-day volume weighted moving average price at the time that the agreements were signed in March 2012. The Jasper shareholders have undertaken not to trade these shares for a period of one year.
• Unwinding of AVR BEE shareholding: A new black economic empowerment partner, which shares the Company's vision and is committed to adding value to Rockwell has been identified. Good progress has been made in terms of securing external funding to cover purchase consideration by the new BEE shareholder in order to finalize the unbundling of the transaction with AVR.

The Company has outlined the way forward for this newly acquired property. Geological studies to estimate the resources at the Jasper Mine are well advanced and the Company is on track to release a NI 43-101 compliant technical statement before the end of May 2013. Initial assessments of the alluvial Jasper deposit suggest that its production profile may be similar to Saxendrift in terms of quality, size and value. Accordingly, by processing materials mined from Jasper at the Company's Saxendrift Mine, there is the potential to extend the life of the Saxendrift operation with limited new investment. The Company is also reviewing the possible construction of an in field screen at Jasper with projected efficiency benefits for the overall operating cost structure of the mine.

"The Middle Orange River region, which is known for its large and high-valued gem-quality diamonds, is a key area of focus for Rockwell, with the Company targeting a processing capacity of 500,000 m^[3] per month of quality gravels. The Jasper Mine project is an important component of this strategy as it provides the potential to extend the mine life of the contiguous Saxendrift Mine," explains James Campbell, CEO, Rockwell Diamonds. "Jasper increases our options within the Saxendrift Complex to grow our production profile, and deliver on our forecast recoveries."

About Rockwell Diamonds:

Rockwell is engaged in the business of operating and developing alluvial diamond deposits, with a goal to become a mid-tier diamond production company. The Company has two operational mines, which it is progressively optimizing, as well as a third mine, Saxendrift Hill Complex, which will come into production in the first quarter of fiscal 2014. Rockwell also has two development projects and a pipeline of earlier stage properties with future development potential. The operations are based on high throughput processing capability and Saxendrift, the flagship mine has among the lowest unit costs in the industry, as a result of implementing fit for purpose technologies.

The Company is known for producing large, high quality gem stone diamonds comprising a major portion of its diamond recoveries and has a beneficiation joint venture that enables it to participate in the profits on the sale of the polished diamonds.

Rockwell also evaluates merger and acquisition opportunities which have the potential to expand its mineral resources and production profile and would provide accretive value to the Company.
