Rockwell provides production update for first quarter of fiscal 2014 ending May 31, 2013

VANCOUVER, July 4, 2013 /CNW/ - Rockwell Diamonds Inc. ("Rockwell" or the "Company") (TSX: RDI; JSE: RDI) today presents a quarterly operational update in line with the Group's strategy. On a consolidated basis, first quarter processed gravel volumes increased by 11% to 893,833m3 year-on-year while diamond production was 33% lower at 4,824 carats, both results inclusive of contractors. The reduction in carat production is mainly the result of the operations at Tirisano being placed on care and maintenance in December 2012 and the sale of Klipdam at the end of March 2013. The production and carat recovery of Saxendrift was consistent, including the recovery of nine stones exceeding 20 carats. The royalty mining contractors operating at the Tirisano property gained momentum with the production of 1,984 carats and the first diamonds were also recovered from the newly commissioned Saxendrift Hill Complex Mine during the quarter.

First quarter operational update:

Volume and carat production for the Company's operational mines for the quarter ended May 31, 2013 was as follows:

Operation Volumes of gravel processed (m3) Carats Produced
Q1 2014 Q1 2013 % change Q1 2014 Q1 2013 % change

Total 893,833 808,468 11% 4,824 7,234 -33%
* Contractors refers to independent royalty contractors processing gravel and sold through the Group's tender. These carats are excluded from grade calculations.

Saxendrift operations and Middle Orange River Prospects:

  • Quarterly volumes of gravel processed at the Saxendrift Mine, all mined at the traditional mining area (Brakfontein), showed a marginal increase of 2% to 461,184m3. The recorded grade of 0.44 carats / 100m3, down from 0.47carats / 100m3 in the prior year, was within the anticipated range for the mine. Carat recoveries for the quarter totaled 2,036 carats, compared to 2,126 carats in the quarter ended May 31, 2012. The mine's production in April 2013 was particularly good, with the recovery of nine stones exceeding 20 carats, of which four exceeded 50 carats.
  • Production ramp up of the Saxendrift Hill Complex mine, based on two Bourevestnik X-ray bulk sorters and two single particle sorters, continued. During this ramp up phase, 269 carats were recovered from 129,427m3 of gravel processed. This is in line with Rockwell's strategy to mine the two-year resource on a block basis, with mining in the first quarter being predominantly in a lower grade block. Several high quality diamonds were recovered.
  • The Company continues to make good progress with its other development projects in the Middle Orange River region as follows:
    • Construction of the new processing plant at Niewejaarskraal Mine is on track and wet commissioning took place early in the second quarter. Management anticipates that the mine will be ramped up to full production within three months.
    • The results of the preliminary economic assessment for Wouterspan showed viable economics and the Company is currently reviewing options to bring this asset to account.


  • Production at Klipdam amounted to 535 carats from 65,702m3 of gravel processed until the sale agreement for the mine was concluded at the end of March 2013. This represents a grade of 0.81 carats per 100m3, down 32% from the comparable quarter in fiscal 2012.
  • In March 2013, the Company accepted an unsolicited cash offer to sell Klipdam for $2.6 million based on the rationale that the mine was considered non-core and the sale proceeds could be better applied to increase production from Rockwell's Middle Orange River properties.

Royalty Mining

  • Three royalty mining contracts were in effect on the Tirisano property during the first quarter, worked by two privately owned alluvial diamond mining operators.
  • A total of 1,984 carats were recovered from 237,520m3 of gravel processed.
  • With two additional contracts awarded, monthly production volumes from the Tirisano royalty mining contracts are set to increase to 150,000m3 by the end of calendar 2013.
  • A further contract for Rockwell's Zwemkuil property, in the Middle Orange River region, has been finalized and projected monthly volumes of 50,000m3 will commence in the second quarter.

"Rockwell's operational performance for the first quarter of fiscal 2014 reflects the transition of the Company as we have narrowed our focus on growing the production profile, from specific footprints that deliver better efficiencies and greater economies of scale. Our first such footprint is the Middle Orange River region," explains James Campbell, CEO and President of Rockwell Diamond. "We have a track record of profitably operating mines in this region which traditionally yields high value gem quality diamonds. The operations at Saxendrift Hill Complex are gaining traction while the Niewejaarskraal operations are being commissioned within three months of presenting the project proposal to the board, a performance milestone for the Company. We are positioned to have three producing mines in the Middle Orange River region by the end of the calendar year. These operations will have a total monthly processing capacity of 370,000m3 against our mid-term objective of 500,000m3. Meanwhile, we are pleased that our three royalty mining contracts at Tirisano delivered the anticipated production during the quarter and we look forward to a positive financial contribution as the two additional contracts come on stream with a total monthly production target of 150,000m3."

About Rockwell Diamonds:

Rockwell is engaged in the business of operating and developing alluvial diamond deposits, with a goal to become a mid-tier diamond production company. The Company's flagship mine is the Saxendrift Mine, in the Middle Orange River and the Saxendrift Hill Complex, which will come into production in the first quarter of fiscal 2014. Rockwell also has two development projects and a pipeline of earlier stage properties with future development potential. The operations are based on high throughput processing capability and Saxendrift has among the lowest unit costs in the industry as a result of implementing fit for purpose technologies.

The Company is known for producing large, high quality gemstone comprising a major portion of its diamond recoveries that is enhanced through a beneficiation joint venture that enables it to participate in the profits on the sale of the polished diamonds.

Rockwell also evaluates merger and acquisition opportunities which have the potential to expand its mineral resources and production profile and to provide accretive value to the Company.
