Rockwell Receives Premium Price for 189.68 Carat Stone: US$10,291,050

Successfully completes September 2008 diamond sale

    <<
        President and CEO John Bristow stated "We are particularly satisfied
        by the outstanding price of US$10,291,050 or US$54,255 per carat
        achieved for this latest large stone of over 100 carats, the fourth
        for the year, recovered from the Klipdam operation. This exceptional
        sales price is most encouraging especially in the context of the
        turbulence in international capital markets and indications that this
        is impacting on world diamond prices.

        Following from these excellent latest diamond sales results for
        production for the period June 1st to August 31st 2008, during
        September the Company achieved strong production results at operating
        costs which are far lower costs than those experienced during our
        previous quarter. Our strong September production reflects the
        positive resolution of the industrial action and is testament to our
        focus on across the board mining and production improvements to
        ensure sustainable long-term cost savings and reduced unit costs. The
        strong decline in oil prices and declining steel prices should
        provide further benefit to the Company is terms of lower operating
        costs."

Run-of-mine diamond production during the period June 1st to August 31st 2008 was 4,266.27 carats, representing approximately 65% of budgeted production. Loss of production was due to industrial action during July and August which was reported in previous Company news releases. Operating cash costs for this period (exclusive of Saxendrift costs) were US$4.65 per tonne, reflecting lower than normal throughput due to industrial action. Operating costs inclusive of Saxendrift were US$5.62 per tonne. September cash operating costs are forecast to be lower than US$4.00 per tonne.

Rockwell realized total revenue of US$4,928,166 for the sale of run-of-mine production of 3,945.84 carats which together with the sale of the large stone realized revenue of US$15,219,216.

There was strong interest in the Rockwell sale reflecting continued high demand for Rockwell rough diamonds. Sales details for production from the individual operations are tabulated below.

Average prices achieved for the different operations were in line with the overall qualities of goods offered up for sale and in all cases the reserve prices were met. Saxendrift production was primarily from lower grade middlings gravels with a lower average diamond size than for June production and this is reflected in lower average price compared to previous sales results. Some softening of prices of smaller and intermediate sized goods in line with seasonal trends, the removal of speculative premiums experienced at the start of this year, and softer international prices were also apparent in the sales results.
