VANCOUVER, June 27, 2012 /PRNewswire/ - Rockwell Diamonds Inc. ("Rockwell" or the "Company") (TSX: RDI) (JSE: RDI) (OTCBB: RDIAF) announces the results of its diamonds sales for the first quarter of fiscal 2013.

Total proceeds of US$5.9 million were generated from the sale of 6,234 carats at an average price per carat for the quarter of US$944. This includes the sale of 1,005 carats from the proof of concept bulk x-ray machine that were sold for an average price per carat of US$853.

The salient features of the fourth quarter diamond sales are as follows:

• The Klipdam Mine achieved a 20% increase in carats sold, as a result of mining the Rooikoppie unit. The average revenue per carat of US$550 was in line with the previous quarter, resulting from the finer diamond distribution in the previously mined Rooikoppie unit, which also has a lower cost of mining.
• Although carats sold from Saxendrift increased 12% year on year, (up 10% quarter on quarter), a lower average price per carat of US$1,727 was recorded. The year on year decline in average price per carat was due to the sale of several high valued stones in the comparative quarter of fiscal 2012, only a handful of which are recovered annually, that significantly raised the average value per carat for that period.
• A total of 1,007 carats recovered from Tirisano were sold during the first quarter at an average price of US$311 per carat. The decrease in average carat value is due to mining a less clay rich unit and the processing of tailings overlying the above unit during the rainy season, which has a smaller average diamond size. This was necessitated by the mine's reliance, in the interim, on dry front-end processing capability. However, this will be chiefly mitigated with the installation of a wet front-end processing system which is currently being commissioned.
• Diamonds recovered from Saxendrift tailings, using the proof of concept bulk x-ray project that was commissioned in April 2012, totaled 1,005 carats. These were sold at an average value per carat of US$853.

"Tangible benefits of our diamond value management initiatives are starting to flow through, with a 44% increase in carats sold in the first quarter from our three operational mines," said James Campbell, CEO, Rockwell. "The sale of 1,005 carats from the pilot bulk x-ray project at Saxendrift also provided an unbudgeted boost to our sales. It is our plan to incorporate this technology into future mining developments and the results of the proof of concept give us confidence in the sales revenues that this technology could unlock for the Company."

Commenting on the diamond market, Campbell explained that: "Diamond prices during the first quarter of fiscal 2013 were stable year-on-year. In the polished market, we saw some pricing pressure, mainly related to the global financial uncertainty. However, this was dampened by growth in demand from India and China. In the USA, especially in affluent market segments, retail sales are showing signs of recovering. We have seen the biggest drop in prices for smaller polished diamond while prices for plus 2 carat stone sizes, which represent more than 80% of Rockwell's production, have been constant. It is our expectation that rough prices will remain stable for the remainder of the calendar year."

Notable Stones

The Company continued to produce large stones at all its operations during the fourth quarter with the recovery of 69 stones exceeding 10 carats:

• Klipdam produced 18 stones exceeding 10 carats, including four stones exceeding 20 carats;
• Saxendrift produced 32 stones that were larger than 10 carats, with four +50 carat stones, including a 92 carat rough diamond;
• Tirisano produced three plus 10-carat stones; and
• The pilot bulk x-ray system produced 16 stones exceeding 10 carats from Saxendrift tailings with the largest weighing 53 carats and 74 carats respectively.

These stones were channelled into the Company's beneficiation joint venture with Steinmetz Diamond Group, which delivers value added revenues for Rockwell's stones that are larger than 2.8 carats.
