Rockwell provides operational update and feedback from third quarter diamond sales

December 15, 2011

VANCOUVER, Dec. 15, 2011 /PRNewswire/ – Rockwell Diamonds Inc. (“Rockwell” or
the “Company”) (TSX: RDI; JSE: RDI; OTCBB: RDIAF) provides an update on
operational progress and the results of its diamond sales for the third
quarter of fiscal 2012.

“We continue to make progress with all the projects that have been set
in motion in the last six months. I can confirm that we are now seeing
evidence of a culture which reflects our diamond value management
strategy being inculcated in the day-to-day operations,” explains James
Campbell, CEO, Rockwell. “In addition to progressing with projects
which will enable our mines to produce according to their plans, we
have also continued to bolster our technical teams to ensure that we
fully benefit from these investments and become more effective at
addressing operational issues on the mines.  Also, following the
agreement reached with the National Union of Mineworkers in November
2011, we have submitted our application to convert the Northern Cape
mines to continuous operations.”

Operational update:

Saxendrift:

        --  Recoveries at the mine were above forecasts for the quarter;
            one stone exceeding 100 carats was recovered.
        --  The Dabmar in field screen has been fully commissioned and has
            been in production at name plate capacity since the end of
            November 2011. The anticipated benefits include its improved
            ability to process various ore types that can efficiently be
            processed through the screen.
        --  The PC2000 excavator was relocated from Klipdam to Saxendrift
            where it is operating at a higher utlization. Its capacity
            matches the 100 ton trucks which transport the gravel from the
            mining faces to the in field screen.
        --  Implementation of the bulk X-ray project is on schedule. The
            X-ray machine will be dispatched from Russia by the end
            December to be set-up in Johannesburg and delivered to the mine
            by the end of January 2012. It is expected to be commissioned
            and incorporated into the dedicated bulk sorting plant to
            commence testing and performance quantification on various
            gravels during April 2012.
        --  Following the construction and commissioning of the mine, the
            first diamonds were produced and have been sold.
        --  The new recovery plant and front-end extension were
            commissioned on schedule during the quarter.
        --  Production started in November 2011 and although diamond grades
            were disappointing, the diamond price achieved was above
            expectation chiefly as a result of higher than expected
            recoveries of +10 carat stones.  Good progress has been made to
            resolve the historical issues of clay balling in the scrubber
            and abundance of manganese in the mine feed which had been
            adversely affecting the concentration and recovery process.
        --  A new plant manager, with vast diamond winning experience and a
            full time, dedicated mining manager have been engaged for the
            mine.
        --  Together with increased supervision and consistent operation of
            the plant, the mine is well placed to achieve planned
            production.
        --  The Company's technical team has been tasked with planning and
            implementing a front end appropriate for run of mine
            preparation before the 2012 rainy season commences.

Klipdam:

        --  A new mine manager started in November 2011 and has already
            made good progress with priorities to increase truck
            availability, achieve consistent plant throughput and reduce
            spillages. As a result, the budgeted recoveries were achieved
            in November 2011.
        --  An infield screen has been erected at the centre of mining
            activities which has resulted in significant diesel cost
            savings.
        --  Early in December 2011, the mining plan migrated to the in situ
            alluvial Rooikoppie gravel which is expected to yield higher
            quality diamonds.

Wouterspan:

        --  The Company has been successful in consolidating its six mining
            and prospecting rights into a single mining right spanning
            7,409 hectares. This milestone will streamline the
            administrative requirements of the authorities as well as any
            future operations. It also provides the Company with
            significant upside to extend the 37.7 million m3 inferred and
            5.0 million m3 indicated resources1 estimated to be contained
            in only 12% of the total consolidated land package.

Third quarter diamond sales

Total proceeds of $6.0 million were generated from the sale of 5,377
carats. The average price per carat for the quarter was $1,109 which
was in line with expectations after having brought Tirisano on stream.

“The volume sold increased by 67% to 5,377 carats, compared to the
second quarter of fiscal 2012. This significant increase is partly due
to the sale of the first production from Tirisano at an average price
of $783 per carat. The Tirisano price per carat greatly exceeds
management estimates”, stated Campbell. “We are well positioned in this
improving diamond market. Our mines are starting to produce to target
and our inventory is 1,800 carats at the end of the third quarter. This
inventory was accumulated so as to satisfy higher demand during the
peak sales period in the first quarter of the 2012 calendar year.”
