Recovery and beneficiation of notable stones:

Production across the Company’s operations, which was disappointing in
June and July 2011, recovered strongly in August 2011. In particular,
373 carats were recovered at Rockwell’s Saxendrift mine on August 2,
2011 which was a daily record at the mine. Large stones produced by
each of the operations during the second quarter are as follows:

        --  Klipdam produced 14 stones exceeding 10 carats; and
        --  Saxendrift produced 32 stones weighing more than 10 carats, of
            which 11 stones exceeded 20 carats

These stones have been passed into the Company’s beneficiation joint
venture with the Steinmetz Diamond Group which delivers value added
revenues for Rockwell’s stones that exceed 2.8 carats.

During the quarter the high quality stones sold through the
beneficiation joint venture with Steinmetz Diamond Group, included the

        --  a 128.67 carat perfect sawable; fancy yellow with high clarity
        --  a  21.52 carat gem quality; clean D/E color stone;
        --  a 33.51 carat octahedral, clean, H/I colored stone; and
        --  a 179.95 carat makeable, clean brown colored stone.

Further details pertaining to the beneficiation revenues will be
disclosed with the second quarter earnings announcement which will be
made on or about October 17, 2011.

Rough Diamond Market:

Although prices remain strong overall, the diamond market has been
impacted by uncertainty in the financial markets in the second quarter
of fiscal 2012. During June and July 2011, prices for both rough and
polished diamonds increased, as higher pricing in the downstream
industry was led by speculative activity. Producers followed suite,
with rough prices achieving all time record levels at the end of July
2011, leading into the summer vacation period. Polished prices
continued to rise, but the pace remains slower than for rough diamonds,
resulting in the continued disconnect between the cost of rough
diamonds and polished prices.

As global financial markets corrected in August 2011, diamond traders
were left holding expensive inventory in uncertain markets. By the end
of August, prices had corrected but are expected to stabilize following
the Hong Kong diamond show and the next De Beers sight later this

Commenting on the latest diamond sales, James Campbell, CEO, Rockwell

“We are pleased that the high quality of our current production has
supported higher selling prices. While the underlying diamond market
has increased by some 25% per carat for diamonds such as those
typically produced by Rockwell in the past twelve months, our average
price for the quarter has more than doubled. This is a clear
demonstration that the diamonds which we have presented for sale are of
a superior quality and in high demand.”

“At the end of August, Rockwell focused its sales on larger diamonds
through our beneficiation JV which benefits from Steinmetz’s ability to
manufacture to achieve value of polished product. We had been
anticipating the short term price consolidation that has occurred in
August 2011. Our products were not sold at a discount to drive sales.”

“We produced 46 stones exceeding 10 carats from our two operational
mines, which included 11 rough stones weighing more than 20 carats.
This is an indication that our diamond value management focus, which
prioritizes the production of quality tons, is starting to pay off.”
