Production and costs: Production statistics for each mine are tabulated below. The average cash costs of production from March 1 to July 31, 2009 (over the Company’s 2010 fiscal year) for the group has been approximately US$2.78 per tonne. A combination of restructuring, efficiency and plant throughput improvements, cost control measures, and increasing production are successfully keeping monthly cash costs below the Company’s target range of US$3.00–3.50 per tonne. This unit cost is expected to remain at the low end of the range as the Company continues to increase production at existing operations and improve processing plant efficiencies.

In response to the greater than 50% decrease in diamond prices in the latter part of 2008, Rockwell suspended diamond sales through late 2008 and early 2009 and resumed sales in late February 2009. Rockwell’s 2009 sales strategy has achieved some success by a combination of direct sales to select buyers and manufacturers and sales by tender. Sales during the first three months of 2009 comprised a combination of direct selling to buyers, and limited tenders sales given overall buying interest was subdued and opportunistic buying patterns were apparent for about 30% of the buyers. Since June, there has been stronger buying interest and attendance at diamond tenders has increased with the numbers of buyers at the latest tenders approaching the levels apparent in 2008. Equally encouraging, prices have remained firm in spite of a large release of diamonds by De Beers in June and the recent resumption of Russian diamond sales.

Overall Rockwell has noted good demand in the 2 to 10 carat rough stone range, with the strongest buying focussed on the 2 to 5 carat market segment. Demand and prices for 3 carat rough stones have been extremely strong since March 2009 and prices realized have been similar to those for early 2008 for better quality goods. Demand and prices for plus 10 carat stones, however, have remained subdued, although top quality white and yellow stones have started to move with prices at about 60 to 75% of last year.

President and CEO John Bristow commented “Rockwell is encouraged by the improvement in buying activities by diamantaires and manufacturers along with the concomitant increase in prices. Based on results to date and our view on demand, sales, and production trends, we foresee a steady overall improvement in prices, albeit staying well below the highs of 2008, for our production going forward through the remainder of the 2009 calendar year. We believe that our swift response to cut costs and production in late 2008 and early 2009 has allowed the Company, largely, to weather the worst of the market conditions. At prices of about US$1,000 per carat and monthly production of 2,400 carats, the Company is cash flow positive, and as prices improve further Rockwell will return to profitability. Rockwell is ideally placed to resume operations at Wouterspan as the market strengthens and thereafter resume its growth and consolidation plans in the medium term.”
