Rockwell operational update

    
           Recovers 122, 120 and 105 carat stones from Saxendrift
                   Monthly production exceeds 2500 carats
    

VANCOUVER, Oct. 5 /CNW/ - Rockwell Diamonds Inc. ("Rockwell" or the "Company") (TSX: RDI; JSE: RDI; OTCBB: RDIAF) provides an update on its operations for the period March 1, 2009 to October 2, 2009.

As a consequence of the international economic crisis and precipitous decline in rough diamond prices, Rockwell restructured its business and operations in January and February 2009 to ensure it could manage the challenges presented by this situation. The Company placed its Wouterspan operation on care and maintenance, reduced its employee complement by a total of 180 personnel, and implemented initiatives to increase production and reduce operating costs. These initiatives included a review of all contracts and out-sourcing arrangements, further refinement of mine plans, stringent grade control, smarter earth moving procedures, re-engineering initiatives to improve production throughput at Saxendrift, Holpan and Klipdam, and rigorous planned maintenance and repair programs at all processing and recovery plants. The Company contracted an experienced engineer with extensive diamond plant (dense media cyclone and rotary pan plant) experience, and capital expenditure programs were cutback to conserve cash.

Plant throughput and diamond recoveries - The initiatives implemented by the Rockwell Board and Management have shown systematic benefit at all operations and resulted in better mining efficiency, increased production, higher diamond recoveries, lower operating costs, and improved operating efficiencies. As a consequence of these initiatives the Company has exceeded its target of 2500 carats per month from its three operating mines during the period June to September 2009. Previously the Company was achieving similar production from four mines. Diamond production data for Rockwell's three active mine sites is summarized in the table below:

Operating costs - Since March 2009, the Company has achieved reductions in its operating costs and has achieved costs at the lower end of its target range of US$3 - $3.50 per tonne since this time. Though not yet operating at full design capacity, the Saxendrift mine, as estimated, has shown encouragingly low operating costs (less than US$3 per tonne). Further cost reductions are expected as plant operations continue to ramp-up.

Production and cost figures for the current financial year to August 31, 2009 are shown in the table below:

Diamond recovery plant - The Company implemented reviews of all final recovery facilities and systems, and made progressive enhancements to tracer test procedures, sorting systems, and security monitoring. These reviews and improvements have been aimed at ensuring sustainable high levels of plant efficiency and optimal security of product. Size frequency plots are conducted routinely to monitor production characteristics. Aside from improved production at Rockwell operations, diamond production profiles at all operating mines have for the six month period ended August 31, 2009 shown systematic trends in line with historical control data and are compatible with modeled or predicted population characteristics. In particular, the Saxendrift mine has met profile expectations with regular recovery of large stones (larger than 10 carats), including the most recent recoveries of stones of 122, 120, and 105 carats in late September/early October 2009.

A brief operational summary is provided for each of the Company's operating mines below:

Saxendrift mine - The new Saxendrift wet Rotary pan plant underwent pre-commissioning in October 2008 and subsequent commissioning in the period February to April 2009. Following improvements to the configuration and retention times of the scrubber units, progress has been made with the performance of the processing plant. This operation is achieving budgeted throughput of approximately 200,000 tonnes per month from the first phase of plant commissioning and operation. Re-engineering and enhancement of this plant is ongoing to further improve throughput and lower operating costs in phase two of the planned plant ramp-up. Mining and operating cash costs achieved at Saxendrift have been lower than originally budgeted, while recovered grades have been in line with estimated grades.

Exceptional stones have been recovered from Saxendrift, including a 40 carat clean white stone in July 2009, and 122, 120, and 105 carat stones during late September/early October 2009. The 122 carat stone is a rounded Octahedra of light yellow ("Cape") colour with a number of inclusions. The 120 carat stone is an irregular rounded and frosted stone which appears to be of good white colour and good clarity. The 105 carat stone is a high quality rounded, top white stone of excellent clarity. These stones are currently undergoing cleaning and appraisal.

The 122 carat stone was recovered from basal gravel deposits being mined in the south west portion of Rockwell's mining right, whereas the 120 and 105 carat stones have red oxide coatings indicating recovery from Rooi Koppie (surface deflation) deposits that are currently being mined and processed. These recoveries are in-line with predictions made from size frequency plots for this deposit. This deposit also yields regular stones in the range of plus 10 to 40 carats, and has yielded two high quality intense yellow stones since July 2009.

Klipdam mine - This operation continues to meet production targets on a regular basis and remains the flagship operation. Progressive enhancements have been made to mining procedures and the processing plant. Operating cash costs are below US$3 per tonne and ongoing refinements to material handling and efficient scheduling of mining and rehabilitation schedules will likely result in further improvements.

Holpan mine - Since March 2009, considerable effort has been devoted to re-engineering of the Holpan dense media separation ("DMS"). A program which has included replacing cyclones in each of the four 50-tonne-per-hour cyclone units, improving vibrating screens and water jet flow for the recovery of ferrous silicon used to control the density medium, swapping out old de-sanding units with two new modified dewatering units to improve water reticulation and save costs, has led to an overall 65% increase in the throughput of the plant and concomitant lowering of costs. This is critical as the DMS plant is a higher cost operating unit than the Company's other rotary pan plants and hence greater throughput and lower operating costs are essential for the sustainability of this plant in a depressed price environment.

Wouterspan mine - In February 2009, this mine was placed on care and maintenance. Since then, all facilities and equipment on this site are being fully maintained and serviced such that this operation could be rapidly re-commissioned when diamond prices have improved to a level where re-opening is justified. The Flow-sort recovery unit and Bateman grease plant have been run intermittently on day shift to maintain this equipment in good standing and to reprocess old tailings which may still contain diamonds that have been recovered from all previous mining ventures on the Saxendrift and Wouterspan terrace. Regular audits of tailings from the Saxendrift mine are also completed at the Wouterspan recovery plant.

The Company has initiated the design and refurbishment of the existing owned plant (including two large scrubbers with throughput in excess of 200 tonnes per hour each, two 18-foot pans, and two 16-foot pans) as a prelude to erecting a completely modernized wet Rotary pan plant at Wouterspan similar to the modular design commissioned at Saxendrift. This low cost operating plant would replace the old Wouterspan plant and in Phase 1 of commissioning would have a throughput of about 200,000 tonnes per month. The modular design configuration would allow for installation of at least two additional double 18-foot pan plants. This addition could significantly enhance the throughput and carat production at Wouterspan and reduce the operating costs as part of a Phase 2 expansion plan.

President and CEO John Bristow stated, "In spite of the world economic recession, precipitous decline in diamond prices, and costly unforeseen corporate activity, Rockwell has demonstrated its ability to rapidly adapt to these challenges. The Company has survived the storm, significantly improved its operating skills and abilities, increased production through smart mining and clever plant improvements, and lowered its operating cost structure. The improvements set in place have ensured that the Company is operating at a break-even point and is well placed to return to profit and grow as diamond prices improve further."
