  • Inventory of 2,752 carats carried forward (includes 1,181 carats on royalty mining contracts).
  • The current 'beneficiation pipeline' of more than 6,000 carats provides additional future revenue potential.
  • Returns from royalty mining contracts deliver net royalties of $1.2 million from five Tirisano contracts and Zwemkuil contract (ceased in third quarter).
  • Net loss for the year narrowed to $10.4 million compared to a loss of $13.8 million in the prior year, after non cash charges of $10.1 million for foreign exchange and depreciation.

Commenting on the fiscal 2014 performance of Rockwell, James Campbell, CEO and President said:

"Our fiscal 2014 results are beginning to reflect the operational turnaround of the Company and its core focus on the Middle Orange River ("MOR") Region of South Africa. Our revenue increased 39% year-on-year to $45.1 million, underpinned by a 52% increase in diamond sales. These improvements have been consistent each quarter over the last two years, as we have now reported seven consecutive quarters of dollar denominated revenue growth. Rockwell reported an operating margin before amortization and depreciation of $6.0 million, compared to $1.1 million in the prior year. Economies of scale as a result of operating exclusively in the MOR also emerged, as production costs for the year increased 25% to $39.2 million, against the 52% improvement in the value of diamond sales. We believe that the implementation of our earthmoving vehicle upgrade programme should unlock further benefits as we improve the fleet overall utilization to match our production capacity and renew the equipment to lower our maintenance expenses while improving availabilities. Equally pleasing is the positive cash flow from normal operations of $3.7 million (prior to working capital movements)."

"From an operational perspective, these results also show that our MOR focus has gained traction. During fiscal 2014, we delivered two new mines, namely Saxendrift Hill Complex ("SHC") and Niewejaarskraal, both funded internally from cash reserves and this  more than doubled our MOR production capacity to 340,000m3 per month. Having met our short-term target to have three producing mines in the MOR, our production profile is now more flexible and sustainable. We are pleased too, that diamond quality and the frequency of larger stones has improved as anticipated. This included the recovery of 12 stones between 50 carats and 100 carats and five plus 100 carat rough diamonds in fiscal 2014, the largest of which was a 287 carat stone, the biggest stone recovered in recorded history in the region. The second phase of the Niewejaarskraal mine was commissioned on schedule at the end of fiscal 2014 and its diamond production performance is improving. At Saxendrift, the plant continues to operate consistently. Once we implement the Earthmoving Vehicle ("EMV") renewal plan, the plant utilization should improve further."

"Looking forward, we remain firmly focussed on our medium term target to process 500,000m3 per month of quality gravels. We are conducting contiguous exploration of existing resources at the Saxendrift Extension property to increase the current life of mine, further leveraging our invested mining infrastructure at Saxendrift. We also have a focused exploration and trial mining programme at SHC to maximize the resource potential and develop contiguous areas. Mining at Niewejaarskraal, where the processing rate approached the monthly nameplate capacity of 100,000m3 at fiscal year-end, is aimed at upgrading the inferred resource to the indicated level. At the same time, we continue to review our options to bring the Wouterspan property to fruition, with a preference for an internally funded and phased approach."

Review of fiscal 2014 delivery on strategy

Rockwell's fiscal 2014 results reflect the benefits of the strategy to grow its MOR production footprint with a mid-term target to increase monthly production volumes of quality gravel processed to 500,000m3. Higher diamond values, better efficiencies and greater economies of scale can be achieved in this region to deliver more consistent quarterly earnings at a more predictable mining cost.

During fiscal 2014, Rockwell achieved further progress against a number of strategic milestones:

  • The short-term goal of delivering three producing operations in the region was met with the commissioning of SHC and Niewejaarskraal, bringing the total monthly processing capacity to 340,000m31.
  • Resources mined from the Saxendrift, Saxendrift Extension, SHC and Niewejaarskraal mining rights all have multiple mining faces, providing production diversification and mining flexibility.
  • Five rough diamonds exceeding 115 carats were recovered in the MOR in fiscal 2014, the largest of which was 287 carats.
  • The three mines in the MOR were all in full production by the fourth quarter. The average stone size in the quarter increased 139% to 4.6 carats, up from 2.0 carats in the prior year when Rockwell had only one MOR operation in production. The anticipated rate of recovery of large diamonds also materialized, with four rough diamonds in the plus 50-carat category being produced in the fourth quarter, compared to two in comparable period of the previous year. 
  • Volumes processed from Rockwell's three MOR mines were up 46% year-on-year, yielding a 12% increase in average grade and carat production up 63% in the region from a year ago.
  • Carat production at the Saxendrift processing plant increased 12% to 9,338 carats, despite a 10% decline in volumes of gravel processed. Its mine life has been extended, at higher overall grades after integrating the newly acquired Saxendrift Extension property into the Saxendrift mine plan.
  • The production ramp up at SHC, the new internally funded Bulk X-ray processing plant, was completed and 3,363 carats were recovered, of which 2,945 carats were sold at an average value of US$2,781 per carat.
  • The Bulk X-ray technology at Saxendrift Hill Complex delivered a grade improvement of more than 40% compared to the traditional Saxendrift pan plant, shown by processing Saxendrift Extension gravels in parallel though both plants.
  • The lossmaking Klipdam mine was sold in April 2013 and the proceeds were reinvested in a new processing plant to bring Niewejaarskraal back into production.
  • A 100,000m3 per month plant was completed at Niewejaarskraal, comprising a DMS (dense media separation), an in field screen and Bulk X-ray system and the throughput reached nameplate capacity by fiscal year-end.
  • A fleet renewal programme to renew the Company's aging fleet is now approved and underway. This will improve earthmoving availabilities and thereby facilitate higher mining volumes at Saxendrift to better utilize the invested processing capacity.
  • The royalty mining contractor strategy, implemented in the prior year, enabled the Company to generate positive returns from properties that it does not wish to mine itself. Value of sales amounts to US$9.4 million, with US$1.2 million in royalties accruing to the Company.
  • The Company reported a gross profit (after amortization and depreciation) of $6.0 milllion compared to a $1.1 million a year ago.

1 This comprises of Saxendrift (160,000m3 / month at a 5mm bottom cut-off size ("BCOS")), SHC (80,000m3 / month at a 5mm BCOS) and Niewejaarskraal (100,000m3 / month at a 6mm BCOS).

For fiscal 2014, processed gravel volumes from Company properties increased 28% to 3,761,062m3 comprising 2,662,901m3 from Rockwell's own operations, and the remainder processed by the royalty mining contractors. Rockwell achieved a 6% grade improvement across the Company's properties to 0.74 carats/100m3, resulting in a 27% increase in total carat production, including 14,222 carats from own operations and 13,554 carats from contractors.

Diamond sales from own operations declined 23% to 13,782 carats, reflecting the transition of the production profile into the MOR that included the sale of Klipdam and termination of mining at the Tirisano property. The five royalty mining contractors who subsequently started operating at Tirisano sold a total of 12,490 carats during the year, resulting in a 27% increase in carat sales from Company-owned properties. The value of sales from own properties was up 34% to US$29.5 million while the average carat value rose 73% to US$2,143, demonstrating immediate benefits of the strategy to focus on the MOR as several large, high value stones were sold into the beneficiation joint venture with Diacore. The value of sales from Company-owned properties improved 43% to US$39.0 million.

Notable metrics of fiscal 2014 production compared to the comparable prior year period are as follows:

During fiscal 2014, the average total cash cost (including rehabilitation and royalties) for all the operations, was US$11.1/m3 compared to a total cash cost of US$10.2/m3 in the prior year. The increase is largely due to the expected higher unit costs incurred at SHC and Niewejaarskraal during production ramp up period at these new mines. On a pro forma basis for continuing operations (excluding Niewejaarskraal and SHC ramp ups), the total cash cost (including rehabilitation and royalty costs) amounted to US$10.9 / m3.

Average cash operating costs and revenues for Rockwell's own operations in US$ during the period are:

Normal operations produced cash flow of $3.7 million (prior to working capital movements) and after working capital movements of $1.1 million and investments amounting to $8.7 million in property plant and equipment (mainly Niewejaarskraal plant), the Company reported a net cash out flow of $4.5 million for the year. At year-end, the Company had made temporary use of its overdraft facilities in the amount of $1.7 million, due to the timing of cash flows from diamond sales which were received shortly after the year end.

Growth projects

Rockwell continues to make progress towards its strategy to increase production from and extend the mine life of its MOR properties:

  • Contiguous exploration of existing resources at the Saxendrift Extension property is under way to increase the current life of mine and to enable the Company to leverage the fixed assets of Saxendrift.
  • A focused exploration and trial mining programme is underway at SHC to ensure the resource potential is maximised and to develop contiguous areas.
  • Through trial mining2, the Niewejaarskraal inferred resource will be upgraded to the Indicated level with the eventual declaration of probable reserves.
  • The Company continues to review the options to bring the Wouterspan property to account following the completion of a preliminary economic assessment in the first quarter of 2013 that reflected viable economics.

Rockwell is also achieving its secondary strategy to leverage the value of certain properties that it does not wish to mine due to size or other reasons. Five royalty contract miners operated at Tirisano during the year with the projected monthly mining volumes at Tirisano now being 200,000m3. The royalty mining contractor agreement at Kwartelspan, which commenced construction in the fourth quarter of fiscal 2014, is in the process of being converted into a joint venture mining arrangement.

The Company continues to evaluate consolidation opportunities in the southern Africa diamond sector that are value accretive. A strict set of criteria are applied to evaluate the potential acquisitions in order to leverage the Company's production expertise towards its goal to become a mid-tier diamond producer.

Because the Niewejaarskraal mine is currently extracting diamonds from an inferred resource, the Company is required under the rule of the NI 43-101, to refer to the mining operations as trial mining.

Market Update

Towards the end of fiscal 2014 rough diamond demand increased, as retailers continued replenishing their polished stock. Polished diamond sales were buoyant, particularly during the December festive season, driven largely by discounting among retailers to drive demand for jewellery. As a result, polished diamond inventories across the industry were depleted, leading to increased liquidity and higher polished prices. December rough diamond sales were in line with historic and sales by major rough diamond producers in January and February 2014 were strong. The open market was extremely active with increased attendance at tenders coupled and higher prices driven by speculation in the secondary market and demand from factories to replenish their work load.

Rockwell continues to support downstream beneficiation of its rough diamonds by backing local South African manufacturing companies. The benefits of the JV with Diacore achieved continued success with some exceptional results on certain large diamonds recovered by Rockwell Diamonds. Demand for high value investment diamonds among high net worth individuals as well as institutional and private investors seeking alternate investment options has been strong, as evidence by results at various auction houses. Prices of investment diamonds continue to break records and based on historical performance these are expected to continue outperforming. Rockwell's primary revenue, through consistent production of high volumes of quality gravels, is from investment type diamonds. Accordingly, its polished product is in the most secure product range with respect price volatility.


The current focus areas for the business are as follows:

  • Rockwell continues to focus on managing its operating costs.
  • At Saxendrift, which plant is operating consistently, the Company's focus is to complete the implementation of the earthmoving vehicle ('EMV') fleet renewal exercise which will improve equipment availabilities to enable the mine to operate at nameplate capacity, while an option to increase the plant capacity is also being reviewed.
  • At SHC, continuous exploration work and trial mining is ongoing to increase this resource. Although the Bulk X-ray recovery system continues to perform on plan, first quarter gravel throughput at the processing plant was impacted by mechanical failures associated with the front end of second hand equipment, which is being addressed as a high priority.
  • At Niewejaarskraal the focus is on consolidating the operations now that the second phase of the 100,000m3 per month plant, has been completed.

Rockwell carried over an inventory of 2,752 carats (including 1,181 contractor owned carats) into the new fiscal year. This, together with a beneficiation pipeline comprising more than 6,000 carats, provides further potential for valued-added downstream revenues. Rockwell continues to beneficiate the vast majority of its diamonds in South Africa. The sale of a 109 polished vivid yellow polished diamond will be reflected in the first quarter beneficiation income and with the MOR focus, the outlook for the beneficiation revenue trend is positive.

About Rockwell Diamonds:

Rockwell is engaged in the business of developing and operating alluvial diamond mines, with the aim of becoming a mid-tier diamond mining company. At February 28, 2014, the Group had three existing mines in operation, namely Saxendrift, Saxendrift Hill Complex and Niewejaarskraal. All three mines are located in the Middle Orange River region.

Rockwell's operations at the Tirisano Mine are on care and maintenance. Royalty mining agreements are in place at Tirisano whereby independent contractors (or royalty miners) mine for own risk and reward, with the Company receiving a 12.5% royalty income based on the carats recovered and sold through the Company's tender process.

A Preliminary Economic Assessment has been completed on the Wouterspan project, which would provide further expansion of the Company's Middle Orange operations in future. The Group has a pipeline of other projects with further future development potential under consideration and evaluation at present.

In addition to its project work, Rockwell continues to evaluate strategic opportunities through merger and acquisition as they arise, in order to expand its mineral resources and provide new opportunities to develop the additional production.

The Group is establishing a track record of producing large gem quality diamonds, which comprise a significant proportion of its production profile. The diamonds recovered from Rockwell's mines are frequently acquired for investment purposes. The Group has a beneficiation agreement in place which enables it to sell rough diamonds, receive 90% of the fair value sales price at sale and receive the remaining 10% through, and participate in, the retail profit on the sale of its +2.8 carat sized stones after polishing and finishing.
