Rockwell Appoints Deon Vermeulen As General Manager Of Its Northern Cape Development And Mining Operations

November 15, 2007 Vancouver, BC – Rockwell Diamonds Inc. (“Rockwell” or the “Company”) (TSXV: RDI; OTCBB: RDIAF) announces the appointment of Deon Vermeulen to the position of General Manager, Northern Cape Development and Mining Operations, of its South African subsidiary H C van Wyk Diamonds Limited. Deon will be replacing previous General Manager Bill Bartholomew who retired at the end of October 2007. Mr. Vermeulen will report to Hennie van Wyk, Operations Director.
Deon Vermeulen obtained a National Higher Diploma in Extractive Metallurgy from the Pretoria University of Technology in 1996. He obtained wide-ranging experience as a production metallurgist in the field of ferro-chrome manufacturing, chrome extraction and chemical manufacturing with Samancor and Bonchem between 1995 and 1997.

He joined De Beers Consolidated Mines in its Kimberley Mines division in 1998. During his tenure at De Beers, he gained considerable experience in kimberlite mining and the hydro metallurgical processing and recovery of diamonds. His activities included communition and diamond liberation studies, Pan-plant and Dense Media Separation (“DMS”) processing and recovery, diamond recovery by X-ray, grease and optical sorter methods, as well as project management, and business and leadership skills in implementation and development.

Senior roles assumed by Mr. Vermeulen at De Beers included responsibility for technical and business unit management at the Kimberley Central Treatment Plant and New Treatment Plant. His role with De Beers also included supervision of low cost small scale projects and empowerment initiatives by De Beers in Kimberley, including Sedibeng and Ekapa, which involved the treatment of tailings material akin to the alluvial deposits mined by Rockwell. Aside from his involvement in South Africa he also obtained experience in the management of exploration processing plants in Canada at the Victor and Grande Priarre projects.

Since joining Rockwell in March 2007, he has been actively involved in the optimization of the Holpan DMS plant where he has contributed to achieving greater throughput and reduction of costs, and the design and scoping of a new Rotary Pan-plant for the Middle Orange River alluvial deposits.

President and CEO John Bristow noted that: “The appointment of Deon Vermuelen, with his proven experience in diamond metallurgy, management and leadership capabilities and, most importantly, his ability to apply practical and cost effective solutions to the Company’s alluvial diamond operations demonstrates further progress in the Company’s drive to build an effective management team to advance our expansion and growth initiatives.”
