³ Includes contribution from mines operated and managed by Rockwell as well as the royalty mining contractors' contribution.

Commenting on second quarter production and sales James Campbell, CEO and President said:

"We are pleased that our second quarter production results reflect continued benefits flowing from our focus on the Middle Orange River region. Volumes of material mined are up 41% to 1.2 million m³, exceeding the one million cubic meter threshold per quarter for the first time. This is a clear demonstration that our three producing MOR mines have gained critical mass and that the implementation of our managed mining strategy, including the EMV renewal plan, is delivering significantly higher EMV availabilities. Volumes of gravel processed, (excluding overburden and a small stockpile of gravels) increased 54% compared to the prior year, providing evidence that our processing plants have risen to the challenge of the higher mining volumes. Accordingly, we are well placed to show a sustainable reduction in unit costs. Carat production rose 6% from our own operations, due to higher volumes of ground processed, offset by lower grades, in the second quarter. These however, were in line with the typical cyclicality of alluvial mining and remained well within the long term average grades for the region.

"As our volumes have increased, so we have benefited from a higher average stone size, which was in excess of 4.5 carats in the second quarter. We produced two gem quality +100-carat diamonds in the second quarter which brings the total to eight +100 carat stones recovered from our operations in the last 12 months: another tangible indicator of the success of our focused MOR strategy. In addition, we recovered thirteen more stones in the +20-carat category, underpinning a 43% increase in carat sales from our own operations and leading to a 36% growth in revenue from diamond sales, excluding beneficiation of US$9.0 million.

"Our five royalty mining contractors at Tirisano continue to deliver positive returns for Rockwell. Second quarter, carat production and carat sales from these partners increased 66% and 70% respectively. Diamond values showed a 30% increase per carat, resulting in the value of sales from contractors rising by 121% to US$4.2 million."

Second quarter operational update:

Volume and carat production for the Company's operational mines for the quarter ended August 31, 2014:

Diamond sales and revenue for the Company's operations for the quarter ended August 31, 2014:

* The Klipdam operation was disposed of during Q1 2014

** Niewejaarskraal product was recovered during plant commissioning and the revenue applied against the Capital Project completed at the end of August 2013.

*** Contractors' mining" refers to independent royalty contractors processing gravel for their own risk and reward on Rockwell owned mineral properties. Carats recovered are then sold through the Company's tender process. The Company retains the responsibility for diamond security and sales and recognize 100% of the revenue on sale. The contractual 87.5% of the sales value, payable to the contractor, is recognized as production costs in the statement of profit and loss.

Changes to MOR Operational Management roles:

At the beginning of the second quarter, Rockwell restructured the management team in the MOR operations to address certain areas of underperformance at the mines. This led to improved overall results for the period under review.

The changes were as follows included:

• Frans Bezuidenhout took on the role of General Manager: MOR, from his previous position as Senior Production Manager at Niewejaarskraal;
• George Stevens was promoted from Geological Manager to Senior Production Manager at Saxendrift; and
• Mulalo Ndwammbi, previously Mining Manager at Saxendrift Hill Complex ("SHC") was promoted to Production Manager: SHC, becoming Rockwell's first black woman production manager.

Saxendrift Operations:

• A capital investment neutral EMV renewal plan was implemented at Saxendrift at the end of June 2014, which included six 100-ton trucks, three front end loaders, two dozers and other associated vehicles. The plan comprises a two year, fully managed lease and maintenance agreement with Eqstra based on a fixed cost per hour of usage with a guarantee of 85% availability, or five hundred operating hours per month per truck.
• Quarterly mining volumes increased 8% year on year, reversing the declines consequent to poor EMV availability recorded in the previous three quarters. Saxendrift achieved record volumes of gravel mined in the months of July and August 2014, demonstrating the benefits of the managed fleet strategy.
• Although quarterly carat production was down 40%, due to mining a lower grade area of the Saxendrift property, the variance is within the expected ranges of long term mine plans and is reflective of the quarterly reporting periods. Mining subsequently reverted to the higher-grade areas at the end of August 2014.
• In spite of reporting a lower total carat production, the quality of recoveries at the mine was high; Saxendrift delivered a 21% increase in average carat values, compensating for the marginal reduction of 4% in carat sales, producing 16% increase revenue from diamond sales (excluding beneficiation).

Saxendrift Hill Complex:

• Quarterly volumes of gravel processed were up 38% from the prior year.
• Processing of recovery tailings negatively impacted the grade, which was down 18%, and size of diamonds.
• The average carat value declined 56%, as a result of the inclusion of several high value stones in the prior year, as well as the smaller stone recoveries in the second quarter. In spite of the 34% increase in carats sold, the mine reported at 42% decline in sales (excluding beneficiation) largely as a result of lower average values realized.

Niewejaarskraal:

• Operations at Niewejaarskraal continue to gain momentum, with a 7.5% increase in volume processed compared to the first quarter of fiscal 2015.
• The mine recorded a grade of 0.54 carats per 100m³ for the quarter, which is in line with the expected grade for this property.
• Carat values, which were up 37% over the prior year, are in line with the long-term average MOR diamond values realized.
• The increases in carat sales and revenue from diamond sales (excluding beneficiation) were about tenfold over the prior year when the mine was newly commissioned, and in production ramp up. 
• Reflecting benefits of increased throughput at Niewejaarskraal, the pace recovery of larger stones has improved, with the largest weighing 62.2 carats for the second quarter.

Royalty Mining Contractors and Joint Venture

• The royalty mining contractors operating on the Tirisano property performed well in the second quarter but lower volumes were processed at the joint venture mining arrangement at Kwartelspan. Total volumes of gravel processed and carats produced were up 64% and 66% respectively on the prior year.
• Carats sales from royalty mining contractors were up 70%, and included the recovery of several high quality stones which underpinned a 30% improvement in average carat values in the second quarter.
• Total revenue generated by the contractors from diamond sales increased 121%, with Rockwell's royalty income amounting to US$523,000.
