Creating a Mid-Tier Diamond Mining

and Development Company with Growth Potential and Leverage

to Exceptional High-Value Gemstones

Investment Highlights

Established operations with scaleable capacity and long-life resources. Rockwell has established operations that yield rare and exceptional high-value gemstone diamonds. Unlike many other diamond companies listed on the TSX, AIM, JSE and ASX, Rockwell’s focus is on development and operations, so the Company has no exploration risk.

Average diamond production is predominantly +2 carat gemstones. Large diamonds (2 carats and above) represent only 7% of world production but account for about 45% of total market value. The Wouterspan, Holpan and Klipdam properties have a record of producing large, high-value gemstones, as refl ected by an average price of US$2,159 per carat achieved for production from its three operations during fi scal 2009.

High quality diamonds. Longer term market data indicates that demand is progressively outpacing supply, which creates a positive environment for Rockwell with leverage to exceptional gemstones. Global fi nancial markets went through an unprecedented period of volatility resulting in a negative impact on the diamond market and a softening of prices. The Company is encouraged by recent price improvements and rough diamond buying activity.

Excellent property location and infrastructure. The Wouterspan, Saxendrift, Holpan and Klipdam properties are adjacent to the Middle Orange River and Vaal River respectively. These localities represent prolifi c alluvial diamond mining regions which have been producing large gemstones since the late 1800s. These areas are in the general vicinity of the city of Kimberley, a recognized diamond centre.

Growth through strategic acquisitions. Rockwell is focused on adding value to existing operations and seeking and acquiring other advanced stage projects. The Company has completed the acquisition of Saxendrift and its south bank Middle Orange River operating facilities and adjacent projects from the Trans Hex Group. These properties, located adjacent to the Company’s Wouterspan operation, provide Rockwell with signifi cant additional diamond bearing gravel resources in the Middle Orange River.

Benefi ciation advantage. Rockwell benefi ciates high-value diamonds in partnership with the Steinmetz Diamond Group to add value to its unique production.

Experienced management and operations team with extensive knowledge of the diamond industry. The Rockwell team has an established and impressive track record in project development and production.

from exceptional high-value gemstones, thereby reducing its reliance solely on tender sales. Although the tender method has served the Company well in the past, diversifying the approach to marketing and sales will assist us to adapt to changing market conditions. The Company’s agreement with the Steinmetz Diamond Group for manufacturing, marketing and sales of selected high-value diamonds through international outlets has generated excellent margins. Rockwell has for example achieved margins of between 10% and 80% on stones sold so far under this unique long-term agreement. This additional revenue received from this agreement provides Rockwell with fl exibility in respect to the diamond sales approach.

Projects

Holpan and Klipdam

The Holpan and Klipdam properties comprise the adjacent Holpan 161 and Klipdam 157 farms, covering 3,836 hectares, located 45km north of Kimberley, South Africa. Holpan is situated within an area of signifi cant alluvial diamond operations, including the Leicester kimberlite diamond mine, from which exceptionally large diamonds have been recovered.

The properties host extensive alluvial diamond deposits. At February 28, 2009 the estimated inferred resource1 is 8,753,163 cubic metres (m3) and indicated resource is 2,272,502 cubic metres (m3) of diamondiferous gravel at a grade of 0.84 carats/100 m3.

Holpan has a history of producing rare fancy stones, including a 7.28 carat intense fl awless pink diamond that sold in November 2007 for US$1.1 million.

Company Profi le

Rockwell Diamond Inc. is focused on creating a growth-oriented mid-tier diamond mining and development company. The Company has acquired interests and rights and established operations in a number of alluvial diamond projects and properties in Southern Africa, including Wouterspan, Saxendrift, Holpan and Klipdam, as well as new prospecting permits. A number of the new permits are adjacent to Rockwell’s Holpan, Klipdam, Wouterspan and Saxendrift operations.

Diamondiferous gravels are present in all of these project-areas, with mineral resources and mining operations at Wouterspan, Holpan, Klipdam, and Saxendrift. Geological mapping and drilling are planned in the new project areas.

Business Strategy – Objectives

The diamond market has been strongly impacted by global fi nancial conditions. Prices of rough diamonds softened appreciably since October 2008 due to a decrease in trade in the rough diamond market. According to some market experts, prices for rough diamonds bottomed out in April and have increased by 15% to 20% since May 2009.

The Company continues to closely monitor these prices and market conditions and when prices are likely to stabilize or increase, this situation is bound to affect Rockwell’s sales prices and revenues going forward. Rockwell implemented a range of operational measures to reduce costs and conserve cash during these uncertain times. Consequently, some of the statements and information presented here could be modifi ed in the short term.

At present our corporate objectives include:

• Leveraging additional value from exceptional gemstone diamond production through strategic value–add initiatives

• Expanding mining and processing operations at the Saxendrift, Holpan and Klipdam properties in South Africa through increased effi ciencies

• Re-commissioning infrastructure, modernizing and recommissioning the processing plant and expanding mining operations at Wouterspan

• Conducting geological investigations and drilling on new project areas adjacent to the above operations

• Driving expansion and growth through acquisitions of select near term alluvial opportunties to increase production.

Benefi ciation

Rockwell is actively implementing several initiatives at the value-added or benefi ciation stage in order to leverage additional revenue

At Holpan, diamond bearing gravels are treated through a modern Bateman Dense Media Separation (DMS) plant with X-ray, grease and hands-off fi nal recovery system.

At Klipdam, diamond bearing gravels are processed through a low-cost, wet rotary pan plant which was completely modernized and upgraded in October 2007.

In September 2008, an exceptional 189.6 carat gemstone was recovered from the Klipdam mine and sold for approximately US$10.3 million.

Wouterspan

The Wouterspan Property comprises portions of the Lanyon Vale 376 farm, totaling 7,407.9 hectares, located near Douglas, South Africa. The property is situated adjacent to the Saxendrift alluvial operation and downstream from the alluvial deposits of the Makoenskloof property.

Due to the dramatic drop in diamond prices in the fall of 2008, Rockwell has placed Wouterspan on care and maintenance. This situation will continue until the diamond values regain sustainable levels. At that stage, a new processing plant is planned for Wouterspan. The construction and commissioning of this plant will be dependent on the state of the diamond market.

The indicated and inferred resources3 estimated for Wouterspan at February 28, 2009 are 5,025,500 cubic metres (m3) and 37,774,000 cubic metres (m3) respectively, grading 0.70 carats/100 m3.

Diamonds of exceptional value have been recovered at Wouterspan, including a 156 carat D-fl awless stone that sold for approximately US$5.7 million and a 152 carat D-colour stone that sold for approximately US$4.3 million at offi cial tender in 2006. A 134 carat yellow stone, a 39.97 carat D fl awless stone and a 41.31 carat light yellow stone were also produced in 2006.

Saxendrift and South Bank Middle Orange River Operations and Projects

In April 2008, Rockwell completed the acquisition of a number of properties on the Middle Orange River. These properties, which include Saxendrift and adjacent Kwartelspan exploration project, are located across the river and adjacent to the Wouterspan operation. The properties provide the opportunity to maximize existing infrastructure and operational synergies.

The Saxendrift property is a past producer with a history of good carat production. During 2008 Rockwell re-commissioned the X-ray fl ow-sort fi nal recovery plant a rotary plant with four pans. During 2009 Rockwell completed the commissioning of the New Wet Rotary pan plant consisting of four 18ft pans and four scrubbers. The plant reached full operating capacity during September 2009. Exceptional stones have been recovered from Saxendrift, including a 40 carat clean white stone in July 2009 and 122, 120 and 105 carat stones during late September/October 2009.

New Prospecting Rights

The Department of Minerals and Energy has granted the Company several new prospecting rights on properties with alluvial gravel deposits. These are located in the vicinity of Holpan and Klipdam, north of Kimberley and Wouterspan and Saxendrift on the Middle Orange River. Low-cost programs are underway to evaluate the potential of these mineral rights.
