Rockwell Announces Fiscal 2009 Results For Three & Six Months Ending August 31, 2008

October 15, 2008, Vancouver, BC – Rockwell Diamonds Inc. (“Rockwell” or the “Company”) (TSX: RDI; JSE: RDI; OTCBB: RDIAF) announces financial results for the three month and six month periods ending August 31, 2008. Financial information is stated in Canadian currency unless otherwise indicated.

Rockwell is focused on growth by mining and developing alluvial diamond deposits. The Company has established a significant footprint on alluvial deposits which consistently yield high value gemstone diamonds. Plus 2-carat stones comprise more than 65% of the Company’s production and are of exceptional quality and value.

Diamond prices remained robust through the six month period ending August 31, 2008 and in September the Company recovered a large white 189.6-carat gemstone from the Klipdam mining operation. This stone realized a sale price of approximately US$10.2 million. This exceptional price was achieved against the background of turbulent conditions in world banking and capital markets which are likely to have an impact on diamond prices going forward.

During the six month period ending August 31, 2008, the Company expanded its operations to four (from an original three operations) with the re-commissioning of operations at Saxendrift on the south bank of the Middle Orange River, adjacent to its Wouterspan operation.

Rockwell is advancing production at the new Middle Orange River operations acquired from the Trans Hex Group, beginning with Saxendrift. Aside from the re-commissioning of the existing small scale Saxendrift plant during the six month period to August 31, 2008, the Company is on target and on budget with the construction of a new state-of-the-art, low-cost, high-volume wet Rotary pan plant on the Saxendrift terrace. Full scale pre-commissioning trials of the refurbished Saxendrift new final recovery facility began three weeks ahead of schedule in late September 2008. Commissioning of the new Saxendrift wet plant is scheduled for November 2008. Once commissioned this plant will add strong growth to the Company’s diamond production profile, and yield further operational costs saving.

The Company experienced loss of production due to industrial action at its operations during the quarter ending August 31, 2008. This action was resolved to the benefit of the Company and its employees in late August and full scale production resumed on September 3, 2008.

In spite of industrial action, which resulted in approximately 35% loss in carat production during the second quarter of fiscal 2009, the Company was able to contain costs and show an operating loss of $155,476 for the period ending August 31, 2008. At a consolidated level, the Company showed a loss of $2.2 million for the period. For the six month period to August 2008 Rockwell showed an operating loss of $7,344 and at a consolidated level a loss of $3 million. Good production rates have been achieved since normal operations resumed on September 3, 2008 and this, combined with cost savings implemented by the Company, will yield reduced operating costs and positive financial performance in the third quarter ending November 30, 2008.

The Company ended the quarter with cash reserves of $10.1 million which will be allocated to future expansion of existing operations, and development of brownfields projects already held by the Company.

Overview and Highlights

Results of Operations

In the first half of fiscal 2009, the Company operated three alluvial diamond mines and re-commissioned operations at its fourth site, Saxendrift. During the period, the Company also increased its interest in the Holpan/Klipdam and Wouterspan properties to 74%, with the remaining 26% being held by a Black Economic Empowerment (“BEE”) consortium.

Industrial action at the Wouterspan mine during the quarter resulted in operations being curtailed at this operation during late July and the month of August. Wage negotiations for all South African operations were implemented in June 2008. These negotiations reached a deadlock in mid August and were followed by work stoppages and reduced production at the Company’s other operations. Negotiations were successfully concluded in late August and full operations were resumed on September 3, 2008.

Production Costs

The average operating cost during the quarter ending August 31, 2008 was US$5.62 per tonne which is inclusive of the Saxendrift start-up operation (by excluding Saxendrift, which is currently in a ramp-up phase, it is US$4.65 per tonne), an increase from US$2.96 per tonne in the quarter ending August 31, 2007. The increased cost per tonne is largely due to the loss of production and throughput related to industrial action experienced during this period.

The average operating cost over six months was US$4.77 per tonne which includes Saxendrift. Excluding Saxendrift, which is currently in a ramp-up phase, the operating cost decreases to US$4.16 per tonne, an increase from US$3.48 per tonne in the six months ending August 31, 2007.

During the first six months of fiscal 2009, the Company focused on implementing costs savings throughout the business, and most particularly in its mining and processing operations. Sustainable costs savings have been achieved through the revision of mine plans, optimization of mining methods and earth moving fleet, the modernization of processing plant, training, and enhancement of productivity. As a consequence of its optimization programs, the Company was able to re-commission operations at Saxendrift during this six month period without having to resort to additional staff recruitment and the purchase of new earth moving fleet.

Cost savings have been reflected in quarterly operating cash costs which have been relatively flat for the past six quarters, in spite of considerable price increases in steel, fuel and oil, electricity, and labour. The benefits of costs savings implemented by the Company will be apparent in forthcoming quarters.

Profit and Loss

The Company had a loss of $2,249,847 for the three month period ended August 31, 2008 compared to a net profit of $431,209 for the comparable period in the prior year. The net losses during the period was primarily the consequence of industrial action and resultant loss of production experienced by the Company during late July and through August 2008.

At August 31, 2008, the Company had working capital of $4,388,435 compared to working capital of $11,837,132 at May 31, 2008 and held total cash reserves of $10.1 million which will be allocated to future expansion of existing operations, and development of brownfields projects already held by the Company.
