Rockwell announces: Extraordinary production of 373 carats in one day at Saxendrift; Finalization by DMR of Section 11 cession: South African Government grants rights for Tirisano Project

VANCOUVER, Aug. 8, 2011 /PRNewswire/ - Rockwell Diamonds Inc. ("Rockwell" or
the "Company") (TSX:RDI; JSE:RDI, OTCBB:RDIAF) announced today that its
Saxendrift mine produced a windfall day's production on August 2, 2011
and stated it had received confirmation of the Section 11 cession by
the Department of Mineral Resources (DMR) for its Tirisano acquisition.

An extraordinary day's production at Saxendrift on Tuesday August 2,

On Tuesday August 2, 2011 373 carats were recovered at Rockwell's
Saxendrift mine representing approximately half of the mine's budgeted
monthly production in a single day. This is not only a record at the
mine, but the highest daily production ever achieved within Rockwell's
five year operating history. Among the stones recovered were four large
stones weighing 180, 94, 43 and 34 carats.

"Rockwell's competitive advantage in the diamond world is the regular
production of large high quality diamonds and although recoveries such
as recently experienced at Saxendrift are rare they enhance the
profitability of our mines." explains Campbell. "Saxendrift has a
similar diamond distribution to both Wouterspan and Niewejaarskraal,
which are next in a pipeline of development projects that Rockwell
plans to bring on stream using improved diamond recovery processes."

Finalization of Section 11 documentation at Tirisano:

Rockwell is pleased to announce that the last outstanding conditions for
the completion of the Tirisano acquisition have been fulfilled. The
senior debt which was provided by the Industrial Development
Corporation was restructured in July 2011 and the Section 11 cession
approval from the DMR was received on Friday August 5, 2011.

Rockwell can now take ownership of the mining rights at Tirisano and
bring the first two streams (production lines) of the newly built
processing plant into commercial production which is planned for the
end of the third quarter.

"We would like to extend our sincere appreciation to the DMR for
diligently following up on the process to ensure that we could complete
our acquisition and unlock the potential of this mine," explains James
Campbell, CEO, Rockwell. "Not only will Tirisano be an important
operation in Rockwell's portfolio but it will create more than 200 jobs
once it is in full production, contributing to the socio economic
development of the Ventersdorp region and more specifically the
economic upliftment of our BEE partners, the local Mogopa community."
