Rockwell to ramp up production profile with finalization of Tirisano acquisition

October 11, 2011 Vancouver, BC – Rockwell Diamonds Inc. (“Rockwell” or the “Company”) (TSX: RDI; JSE: RDI; OTCBB: RDIAF) announces the completion of the Tirisano Mine project acquisition. The effective date of the transaction is September 1, 2011 on a going concern basis, although the operation has been on a care and maintenance arrangement for two years.

“We are delighted that this transaction has now been completed as Tirisano is of strategic importance to Rockwell’s long term growth objectives. The quality and price per carat of the stones recovered at Tirisano during the commissioning and recovery testing phase are encouraging as these exceeded what was achieved by the mine’s previous operators,’ commented James Campbell, CEO, Rockwell. “We are confident that the mine will make a meaningful contribution to our objective of sustainably ramping up Rockwell’s production profile. We also anticipate that over the long term, the mine will enhance the Company’s cash flows and plan to apply these to create the maximum long term returns for shareholders.”

On September 9, 2010 Rockwell Resources RSA (Pty) Limited signed a Sale of Shares and Claims Agreement with Etruscan Diamonds Bermuda Limited, Etruscan Diamonds Limited and Etruscan Resources Inc. whereby the Company agreed to acquire Etruscan’s Blue Gum Diamond operation in the Ventersdorp region of South Africa.

The acquisition was for 100% of the equity in Etruscan Diamonds (Pty) Limited (an exploration company) and 74% in Blue Gum Diamonds (Pty) Limited (“the acquired companies”). The balance of the equity in Blue Gum Diamonds (Pty) Limited is owned by the Company’s BEE partner, the local Mogopa community, in accordance with the South African Mining Charter. Blue Gum Diamonds Pty Limited owns the Tirisano mining right and the operation has been on care and maintenance since June 2008.

Final Acceptance and Release documents were signed on October 7, 2011 pursuant to all the conditions precedent being met (including the mineral property transfer approval and the IDC’s commitment to consolidate the Company’s debt finance with deferred payment terms).

A third condition to the transaction has been the commitment of the local Mogopa community to its continued partnership with the Company through its support and involvement. This is a key business requirement in order to resume and build a sustainable mining operation at Tirisano.

The purchase consideration of ZAR33.5 million ($4.65 million) is funded by:

  • Internal funding – care and maintenance advances / net debt and working capital movements amounting to ZAR14.5 million ($2.01 million); and
  • Equity funding – the issue of 2.6 million Rockwell Diamonds Inc (RDI) ordinary shares to settle the balance of ZAR19.0 million ($2.64 million). The effective share price was established in September 2010, determining the number of shares to be issued.

The Company has established a mining fleet, processing plant and final recovery capacity on site over the past eighteen months in order to progress to commercial production. The mine has a current production capacity of 90 000 m3 per month. Plant modifications were completed in-house, using unutilized existing plant and machinery which was redeployed from Rockwell’s Wouterspan and other Northern Cape mines. In particular, the Company addressed the issues with the front end and recovery which were revealed during the plant review in June 2011. The fully containerized Holpan recovery plant has been relocated to Tirisano and a barrel screen from Wouterspan has been installed which doubled the front end capacity as an interim solution. This two-stream production volume plant is expected to benefit the Company by smoothing its production profile and production ramp-up has started.

During the next six months, the focus at Tirisano will be on optimising the mining and plant efficiencies including the development of long term solutions for the front end. Work will also continue on the concept designs to increase the plant’s capacity.

Rockwell continues to mine as per its medium term plan and will continue to work with SRK Consulting Africa to develop the geotechnical parameters that are being used by open pit mining consultancy, Tacmin Madini to finalise the optimised mine design and extraction plan.
