ROCKWELL DIAMONDS INC.                                                          
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS                                  
For the years ended May 31, 2007 and 2006 and the nine months ended February    
29, 2008                                                                        
(Expressed in Canadian Dollars unless otherwise stated)                         
1.   NATURE AND CONTINUANCE OF OPERATIONS                                       
Rockwell Diamonds Inc. (the "Company") is incorporated under the British        
Columbia Business Corporations Act (formerly the Company Act of British         
Columbia), and is engaged in the business of diamond production, and the        
acquiring and exploring natural resource properties.  The Company`s principal   
mineral property interests are located in South Africa.                         
These consolidated financial statements are prepared in accordance with         
Canadian generally accepted accounting principles.  In December 2007, the       
Company`s Board of Directors approved a resolution to change the Company`s      
year end from May 31, 2008 to February 29, 2008.                                
During the year, the Company listed with the Toronto Stock Exchange ("TSX")     
and also had a listing on the Johannesburg Stock Exchange ("JSE").              
The Company has estimated that it will have adequate funds from existing        
working capital to meet its corporate, operational, development,                
administrative and property obligations for the coming year. The Company will   
periodically need to obtain additional financing, and while it has been         
successful in the past, there can be no assurance that it will be able to do    
so in the future.                                                               
The recoverability of the amounts shown for the Company`s mineral property      
interests, property, plant and equipment and inventory is dependent upon the    
existence of economically recoverable mineral resources and future profitable   
production or proceeds from the disposition of the mine.  The Company`s         
continuing operations are also dependent upon the discovery and existence of    
economically recoverable mineral reserves, the ability of the Company to        
obtain the necessary financing to complete the exploration and development of   
its mineral property interests, and upon future profitable production or        
proceeds from the disposition of its mineral property interests.                
These consolidated financial statements do not include adjustments to amounts   
and classifications of assets and liabilities that might be necessary should    
the Company be unable to continue operations.                                   
2.   Basis of presentation and principles of consolidation                      
These consolidated financial statements have been prepared in accordance    
with Canadian generally accepted accounting principles.  These consolidated     
financial statements include the accounts of the Company and its wholly-owned   
subsidiaries.  All significant intercompany balances and transactions have      
been eliminated upon consolidation. Certain comparative information has been    
reclassified to conform to the presentation adopted in the current period.      
3.   Significant accounting policies                                            
(a)  Cash and equivalents                                                       
Cash and equivalents consist of cash and highly liquid investments,         
having maturity dates of three months or less from the date of purchase, that   
are readily convertible to known amounts of cash and which are subject to an    
insignificant risk of change in value.  At February 29, 2008, of the            
$19,623,847 (May 31, 2007 - $32,626,376) cash and equivalents held by the       
Company, $15,698,068 (ZAR 124,095,041) were held in South African Rand          
("ZAR"), $35,772 ($16,553,541) were held in Chilean Pesos and $9,974            
($10,036) in US Dollars.                                                        
(b)  Revenue recognition                                                        
Revenue from rough diamond sales is recognized when persuasive evidence of an   
arrangement exists, delivery has occurred, the Company`s price to the           
customer is fixed or determinable and collection of the resulting receivable    
is reasonably assured.                                                          
(c)  Trade accounts receivables                                                 
Trade accounts receivables are recorded at the invoiced amount less an          
estimate made for doubtful accounts based on a review of all outstanding        
amounts on a quarterly basis. Account balances are charged off against the      
allowance after all means of collection have been exhausted and the potential   
for recovery is considered remote.                                              
(e)  Inventory                                                                  
Rough diamond inventory is recorded at the lower of production cost and net     
realizable value. Production costs include the cost of consumable materials,    
direct labour, mine-site overhead expenses and amortization.                    
Supplies inventory is valued at the lower of average cost and replacement       
cost.                                                                           
Plant and equipment                                                             
Plant and equipment are stated at cost less accumulated amortization.  Assets   
are amortized on a straight-line method over the estimated useful lives of      
the related assets, which are as follows:                                       
Processing plant and equipment          4 - 10 years                            
Office equipment                        6 years                                 
Vehicles and light equipment            5 years                                 
Repairs and maintenance expenditures are charged to operations as incurred.     
Significant improvements and major replacements which extend the useful life    
of the asset are capitalized as incurred.                                       
(f)  Reclamation and security deposits                                          
Reclamation and security deposits are recorded at cost.                     
(g)  Mineral property interests                                                 
The acquisition costs of mineral properties are capitalized until the           
property is placed into production, sold, or abandoned, or when management      
has determined that there has been an impairment in value.  Such acquisition    
costs are amortized over the estimated life of the property, based on the       
unit of production method, or written off to operations if the property is      
abandoned, allowed to lapse, or if there is little prospect of further work     
being carried out by the Company.                                               
Mineral property acquisition costs include the cash consideration and the       
fair market value of common shares, based on the trading price of the shares,   
on the date of issue or as otherwise provided under the agreed terms for the    
mineral property interest.                                                      
Exploration costs and option payments are expensed in the period incurred.      
Administrative expenditures are expensed in the period incurred.                
The amount presented for mineral property interests represents costs incurred   
to date and accumulated acquisition costs, less write-downs, and does not       
necessarily reflect present or future values.                                   
(h)  Financial instruments                                                      
The Company`s financial instruments consist of cash, restricted cash, amounts   
receivable, trade receivables from a related party, reclamation deposit,        
accounts payable and accrued liabilities,  capital lease obligations, amounts   
owing pursuant to acquisition and balances payable to related parties.  It is   
management`s opinion the Company is not exposed to significant interest,        
currency or credit risk arising from these financial instruments.  The fair     
values of these financial instruments approximate their carrying values,        
unless otherwise noted.                                                         
(i)  Site closure and reclamation obligations                                   
The Company accounts for site closure and reclamation costs in accordance       
with Canadian Institute of Chartered Accountants ("CICA") Handbook Section      
3110, "Asset Retirement Obligations" (HB 3110). HB 3110 requires the            
recognition of any statutory, contractual or other legal obligation related     
to the retirement of tangible long-lived assets when such obligations are       
incurred, if a reasonable estimate of fair value can be made.                   
These obligations are measured initially at fair value and the resulting        
costs are capitalized to the carrying value of the related asset. In            
subsequent periods, the liability is adjusted for the accretion of the          
discount and any changes in the amount or timing of the underlying future       
cash flows. The asset retirement cost is amortized to operations over the       
life of the asset. Changes resulting from revisions to the timing or the        
amount of the original estimate of undiscounted cash flows are recognized as    
an increase or a decrease in the carrying amount of the liability, and the      
related asset retirement cost is capitalized as part of the carrying amount     
of the related long-lived asset.                                                
(j)  Impairment of long-lived assets                                            
Long-lived assets, including mineral properties, plant and equipment, are       
reviewed for impairment whenever events or changes in circumstances indicate    
that the carrying value of an asset may not be recoverable.  Recoverability     
of assets to be held and used is measured by a comparison of the carrying       
amount of an asset to estimated undiscounted future cash flows expected to be   
generated by the asset. If the carrying amount of an asset exceeds its          
estimated future cash flows, an impairment charge is recognized by the amount   
by which the carrying amount of the asset exceeds the fair value of the         
asset. Assets to be disposed of would be separately presented in the balance    
sheet and reported at the lower of the carrying amount and the fair value       
less costs to sell, and are no longer amortized.                                
(k)  Foreign currency translation                                               
All of the Company`s foreign operations are considered integrated.              
Monetary assets and liabilities of the Company and its integrated foreign       
operations are translated into Canadian dollars at exchange rates in effect     
at the balance sheet date.  Non-monetary assets and liabilities are             
translated at historical exchange rates unless such items are carried at        
market, in which case they are translated at the exchange rates in effect on    
the balance sheet date.  Revenues, cost of sales and expenses, except           
amortization, are translated at the average exchange rates for the period.      
Amortization is translated at the same exchange rate as the assets to which     
it relates.  Gains or losses on translation are recorded in the statement of    
operations.                                                                     
(l)  Share capital                                                              
Common shares issued for mineral property interests are recorded at their       
fair market value based upon the trading price of the shares on the Toronto     
Stock Exchange ("TSX") on the date of issue or as otherwise provided under      
the terms of the agreement to issue the shares. Share issue costs are           
deducted from share capital.                                                    
(m)  Stock-based compensation                                                   
The Company has a share option plan which is described in note 10(b).  The      
Company records all stock-based payments granted using the fair value method.   
Under the fair value method, stock-based payments are measured at the fair      
value of the consideration received or the fair value of the equity             
instruments issued, whichever is more reliably measurable, and are charged to   
operations over the vesting period, with an offsetting amount to contributed    
surplus.  Consideration received on the exercise of stock options is recorded   
as share capital and the related contributed surplus is transferred to share    
capital.                                                                        
(n)  Income taxes                                                               
The Company uses the asset and liability method of accounting for income        
taxes.  Under this method, future income tax assets and liabilities are         
computed based on differences between the carrying amount of assets and         
liabilities on the balance sheet and their corresponding tax values,            
generally using the enacted or substantively enacted income tax rates           
expected to apply to taxable income in the years in which those temporary       
differences are expected to be recovered or settled.                            
Future tax assets are recognized to the extent that they are considered more    
likely than not to be realized.  The valuation of future income tax assets is   
adjusted, if necessary, by the use of a valuation allowance to reflect the      
estimated realizable amount.                                                    
(o)  Loss per share                                                             
Basic income (loss) per share is calculated by dividing the loss for the        
period by the weighted average number of common shares outstanding during the   
period.                                                                         
Diluted income (loss) per share is calculated using the treasury stock          
method.  Under the treasury stock method, the weighted average number of        
common shares outstanding used for the calculation of diluted income (loss)     
per share assumes that the proceeds receivable upon exercise of dilutive        
share purchase options and warrants are used to repurchase common shares at     
the average market price during the period.                                     
Diluted loss per share has not been presented separately as the effect of       
outstanding options and warrants would be anti-dilutive.                        
(p)  Use of estimates                                                           
The preparation of consolidated financial statements in conformity with         
Canadian generally accepted accounting principles requires management to make   
estimates and assumptions that affect the reported amounts of assets and        
liabilities and the disclosure of contingent assets and liabilities as at the   
balance sheet date, and the reported amounts of revenues and expenses during    
the reporting period.  Significant areas requiring the use of management        
estimates relate to the impairment of mineral property interests,               
determination of reclamation obligations and the assumptions used in            
determining stock-based compensation expense.  Actual results could differ      
from those estimates.                                                           
4.   CHANGES IN ACCOUNTING POLICIES                                             
(a)  Newly Adopted Accounting Policies                                          
Effective June 1, 2007, the Company adopted the following new accounting        
standards issued by the Canadian Institute of Chartered Accountants ("CICA")    
relating to financial instruments. These new standards have been adopted on a   
prospective basis with no restatement to prior period financial statements.     
(i)  Section 3855 - Financial Instruments - Recognition and Measurement         
This standard sets out criteria for the recognition and measurement of          
financial instruments for fiscal years beginning on or after October 1, 2006.   
This standard requires all financial instruments within its scope, including    
derivatives, to be included on a Company`s balance sheet and measured either    
at fair value or, in certain circumstances when fair value may not be           
considered most relevant, at cost or amortized cost. Changes in fair value      
are to be recognized in the statements of operations and comprehensive          
income, depending on the classification of the related instruments.             
All financial assets and liabilities are recognized when the entity becomes a   
party to the contract creating the item. As such, any of the Company`s          
outstanding financial assets and liabilities at the effective date of           
adoption are recognized and measured in accordance with the new requirements    
as if these requirements had always been in effect. Any changes to the fair     
values of assets and liabilities prior to June 1, 2007 are recognized by        
adjusting opening deficit or opening accumulated other comprehensive income.    
All financial instruments are classified into one of the following              
categories: held for trading, held-to-maturity and available-for-sale           
financial assets. Initial and subsequent measurement and recognition of         
changes in the value of financial instruments depends on their initial          
classification:                                                                 
-    Held-to-maturity investments, loans and receivables, and other financial   
liabilities are initially measured at fair value and subsequently measured at   
amortized cost. Amortization of premiums or discounts and losses due to         
impairment are included in current period net earnings.                         
-    Available-for-sale financial assets are measured at fair value. Changes    
in fair value are included in other comprehensive income until the gain or      
loss is recognized in income.                                                   
-    Held for trading financial instruments are measured at fair value. All     
gains and losses are included in net earnings in the period in which they       
arise.                                                                          
-    All derivative financial instruments are measured at fair value, even      
when they are part of a hedging relationship. Changes in fair value are         
included in net earnings in the period in which they arise, except for hedge    
transactions which qualify for hedge accounting treatment in which case gains   
and closes are recognized in other comprehensive income.                        
On adoption of the standards on June 1, 2007, the Company`s outstanding         
financial assets and liabilities were recognized and measured in accordance     
with the new requirements as if these requirements had always been in effect.   
However, no adjustments to opening deficit or opening accumulated other         
comprehensive income were required.                                             
In accordance with this new standard, the Company has classified its            
financial instruments as follows:                                               
-    Cash and restricted cash are classified as held for trading financial;     
instruments and are measured at fair value due to their short term nature and   
availability for prompt liquidation.                                            
-    Amounts receivables and trades receivable from a related party are         
classified as loans and receivables and are measured initially at fair value    
and subsequently measured at amortized cost.                                    
-    Accounts payable and accrued liabilities, amounts owing pursuant to        
acquisition and balances payable to related parties are classified as other     
financial liabilities and are measured initially at fair value and              
subsequently measured at amortized cost.                                        
-    Reclamation deposits invested in interest bearing money market linked      
investments are classified as available-for-sale securities and are carried     
at fair market value, with the unrealized gain or loss recorded in              
shareholders` equity as a component of other comprehensive income. During the   
period there were no unrealized gains or losses relating the reclamation        
deposits as the carrying amounts approximate the fair value. Previously,        
reclamation deposits were carried at cost, less provision for other than a      
temporary decline in value.                                                     
(ii) Section 3865 - Hedges.                                                     
This new standard specifies the circumstances under which hedge accounting is   
permissible and how hedge accounting may be performed.  The Company currently   
does not have any financial instruments which qualify for hedge accounting.     
(iii)     Section 1530 - Comprehensive Income.                                  
Comprehensive income is the change in the Company`s shareholder equity that     
results from transactions and other events from other than the Company`s        
shareholders and includes items that would not normally be included in net      
earnings, such as unrealized gains or losses on available-for-sale              
investments. This standard requires certain gains and losses that would         
otherwise be recorded as part of net earnings to be presented in other          
"comprehensive income" until it is considered appropriate to recognize into     
net earnings.  This standard requires the presentation of comprehensive         
income, and its components in a separate financial statement that is            
displayed with the same prominence as the other financial statements.           
Accumulated other comprehensive income is presented as a new category in        
shareholders` equity.  As at February 29, 2008, the Company had no              
accumulated other comprehensive income and for the period, comprehensive        
income (loss) equals net loss.                                                  
(iv) Section 1506 - Accounting Changes                                          
This standard establishes criteria for changing accounting policies, together   
with the accounting treatment and disclosure of changes in accounting           
policies, changes in accounting estimates and correction of errors. As a        
result, changes in accounting policies are only permitted when required by a    
primary source of generally accepted accounting principles or when the change   
will result in more reliable and more relevant information.                     
(b)  Accounting Policies Not Yet Adopted                                        
(i)   Section 1535 - Capital Disclosures                                        
This standard requires disclosure of an entity`s objectives, policies and       
processes for managing capital, quantitative data about what the entity         
regards as capital and whether the entity has complied with any capital         
requirements and, if it has not complied, the consequences of such non-         
compliance. This standard is effective for the Company for interim and annual   
periods relating to fiscal years beginning on or after January 1, 2008, The     
Company is currently evaluating the effects of adopting this standard.          
(ii) Financial Instruments - Disclosure (Section 3862) and  Presentation        
(Section 3863)                                                                  
These standards replace CICA 3861, Financial Instruments - Disclosure and       
Presentation. They increase the disclosures currently required, which will      
enable users to evaluate the significance of financial instruments for an       
entity`s financial position and performance, including disclosures about fair   
value. In addition, disclosure is required of qualitative and quantitative      
information about exposure to risks arising from financial instruments,         
including specified minimum disclosures about credit risk, liquidity risk and   
market risk. The quantitative disclosures must provide information about the    
extent to which the entity is exposed to risk, based on information provided    
internally to the entity`s key management personnel. This standard is           
effective for the Company for interim and annual periods beginning on or        
after January 1, 2008. The Company expects that its disclosures will be         
expanded to incorporate the additional requirements.                            
(iii)     Amendments to Section 1400 - Going Concern                            
CICA 1400, General Standards of Financial Statement Presentation, was amended   
to include requirements to assess and disclose an entity`s ability to           
continue as a going concern. The new requirements are effective for interim     
and annual financial statements relating to fiscal years beginning on or        
after January 1, 2008. The Company is currently evaluating the impact of this   
new standard.                                                                   
(iv) International Financial Reporting Standards ("IFRS")                       
In 2006, the Canadian Accounting Standards Board ("AcSB") published a new       
strategic plan that will significantly affect financial reporting               
requirements for Canadian companies.  The AcSB strategic plan outlines the      
convergence of Canadian GAAP with IFRS over an expected five year               
transitional period.  In February 2008, the AcSB announced that 2011 is the     
changeover date for publicly-listed companies to use IFRS, replacing Canada`s   
own GAAP.  The date is for interim and annual financial statements relating     
to fiscal years beginning on or after January 1, 2011.  The transition date     
of January 1, 2011 will require the restatement for comparative purposes of     
amounts reported by the Company for the year ended December 31, 2010.  While    
the Company has begun assessing the adoption of IFRS for 2011, the financial    
reporting impact of the transition to IFRS cannot be reasonably estimated at    
this time.

Title to mining properties involves certain inherent risks due to the           
difficulties in determining the validity of certain claims as well as the       
potential for problems arising from the often complicated conveyancing          
history characteristic of many mining properties.  The Company does not have    
title insurance but has investigated title to its Ricardo mineral property      
and, to the best of its knowledge and belief, title to its property is in       
good standing.                                                                  
(a)  Acquisition of Durnpike Investments (Pty) Limited                          
On June 30, 2006, the Company entered into an Agreement-in-Principle to         
acquire interests and/or rights in four alluvial diamond properties in South    
Africa and the Democratic Republic of Congo. These four properties include      
the Holpan/Klipdam Property in South Africa, Wouterspan Property in South       
Africa, Kwango River Project in the Democratic Republic of Congo and Galputs    
Minerale Project in South Africa.                                               
Subsequently, pursuant to the terms of the Definitive Agreement, the Company    
acquired all of the shares and loans in Durnpike, a private South African       
company, from eight vendors (the "Vendors") for consideration set forth         
below, payable in common shares of the Company ("Common Shares") related to     
the closing price of the Common Shares on the TSX Venture Exchange on the       
specified dates described below. Durnpike holds an interest in respect of       
and/or rights in the four alluvial diamond properties.                          
The Holpan/Klipdam Property and the Wouterspan Property were indirectly owned   
by the H.C. Van Wyk Diamante Trust ("Van Wyk Trust"), a business trust          
registered in South Africa. The Van Wyk Trust held 99% of HC Van Wyk Diamonds   
Ltd ("HCVW"), a private South African company, and 99% of Klipdam Mining        
Company Limited ("Klipdam"), a private South African company. The remaining     
1% of HCVW and Klipdam was owned by nominees of the Van Wyk Trust. HCVW and     
Klipdam, and were collectively referred to as The Van Wyk Diamond Group of      
companies ("VWDG").                                                             
On July 7, 2006, Durnpike completed the acquisition of an initial 49% of the    
issued and outstanding shares of HCVW and 51% of the issued and outstanding     
shares of Klipdam (the "Acquisition Interest") for South African Rand ("ZAR")   
50 million ($7.8 million) and agreed to pay an additional ZAR30 million ($4.5   
million) to the Van Wyk Trust on July 7, 2007.                                  
To facilitate Durnpike`s payment of ZAR50 million to the Van Wyk Trust on       
July 7, 2006, the Company advanced a non-interest bearing loan to Durnpike of   
ZAR50 million (Cdn$7.8 million). This loan is secured by a pledge of            
Durnpike`s Acquisition Interest. The payment of ZAR30 million was made to the   
Van Wyk Trust in June 2007.                                                     
Durnpike had the option to increase its shareholding in HCVW to a 51%           
controlling interest by (a) subscribing for additional shares in HCVW for the   
amount of ZAR1 million ($160,000) and (b) introducing a ZAR24 million ($3.9     
million) working capital loan into VWDG. These conditions were met in January   
2007.                                                                           
The Company also entered into an Exchange Agreement with the Van Wyk Trust to   
acquire the remaining shareholding of VWDG for ZAR60 million ($7.6 million),    
payable in Common Shares.  The Exchange Agreement became effective upon         
Rockwell completing its listing of the Company`s Common Shares on the JSE. In   
March 2008, subsequent to the nine months ending February 29, 2008, pursuant    
to the Exchange Agreement the Company issued Common Shares to the Van Wyk       
Trust and increased its ownership by 23% to a total of 74% of the VWDG          
assets.                                                                         
Pursuant to the Definitive Agreement, the Company:                              
-    acquired from the Vendors all of their shares and loans in Durnpike for    
consideration of ZAR 39.8 million ($6.1 million), payable in common shares of   
the Company on the earlier of (i) the date of the JSE listing; and (ii)         
within approximately 12 months from signature of the Definitive Agreement. By   
virtue of such acquisition, the Company acquired Durnpike`s interests in the    
four alluvial diamond properties in South Africa and the Democratic Republic    
of Congo ("DRC"). The ZAR consideration does not include payment in respect     
of the Kwango River Project, which payment stands to be made by the Company     
only when (and if) the feasibility study referred to below has been completed   
and approved by the board of directors of the Company.                          
On November 30, 2007, the Company began trading on the Johannesburg Stock       
Exchange and hence completed its JSE listing condition.  Consequently, the      
Company issued 7,848,663 Common Shares as settlement of its commitment of ZAR   
39.8 million ($6.1 million) and also 1,676,529 Common Shares as finder fees     
relating to the Durnpike acquisition.                                           
-    will spend US$7 million on a feasibility study on the Kwango River         
Project by August 31, 2007. This deadline may be extended to February 29,       
2008 at no cost and be further extended to December 31, 2008 by payment of      
US$1 million in Common Shares. As it seems highly unlikely that the deadline    
of February 29, 2008 will be met, the Company is currently negotiating an       
extension to such deadline. If the Company wishes to retain the Kwango River    
Project following completion of the feasibility study, the Company must (i)     
pay to the Vendors an amount equal to 60% of the net present value of the       
Kwango River Project Valuation (as determined in terms of the feasibility       
study and subject to a minimum acquisition cost of US$13 million and a          
maximum acquisition cost of US$26 million), which payment shall be effected     
by the issuance of Common Shares and (ii) commit to incur an additional         
amount of up to US$6 million in expenditures for development of the Kwango      
River Project within 16 months from the date of completion of the feasibility   
study. If the Company does not wish to retain the Kwango River Project          
following completion of the feasibility study, the Definitive Agreement         
provides for Durnpike being divested of such project on certain terms, with     
the Company nevertheless retaining 100% of the shares in Durnpike (and          
therefore the indirect interests in the Holpan/Klipdam, Wouterspan and          
Galputs properties). In such event, the full and final purchase consideration   
for Durnpike will be limited to the ZAR Consideration.                          
Durnpike`s interest in the Kwango River Project is constituted by an            
agreement ("Midamines Agreement") with Midamines SPRL ("Midamines"), the        
holder of the exploration permit on the Kwango River Project, to act as         
contractor on behalf of Midamines to manage and carry out exploration and       
mining. Durnpike will be entitled to an 80% share of the net revenue from the   
sale of any diamonds produced from the contract area.                           
Under the Midamines Agreement, Durnpike agreed to certain minimum royalty       
payments being made to Midamines. These royalties take the form of a series     
or recurring annual minimum royalty payments of US$1,200,000 per annum          
(commencing on December 31, 2007). (As to the enforceability of this            
commitment in light of developments pertaining to the Midamines Agreement,      
see note 14 (a)).  During the third quarter of fiscal 2008 the Company paid     
consideration of $600k to Midamines in order to increase the size of the        
concession.                                                                     
All of the Common Shares issued to the Vendors pursuant to the acquisition,     
other than the Common Shares issued to extend the feasibility study deadline,   
will be held in escrow for at least nine months from the date of issuance,      
provided that a limited portion of those escrowed Common Shares may be          
released to enable the Vendors to meet certain specified obligations.           
On January 31, 2007, all the conditions precedent to implementation of the      
Acquisition as per the Definitive Agreement were fulfilled. The Company also    
received the necessary regulatory approvals in Canada and South Africa. As      
provided for in the Definitive Agreement, the Company executed an agreement     
in relation to the acquisition of control of the mineral rights relating to     
the Galputs Minerale Project. To date the Company is still awaiting the         
Department of Minerals and Energy`s ("DME") final approval relating to the      
transfer of the shares of Galputs Minerale Project from Virgilia Investments    
Inc. to the Company.                                                            
During the year ended May 31, 2007, a black economic empowerment ("BEE")        
group purchased 15% of the VWDG from the Van Wyk Trust for an amount of ZAR     
22.5 million (Cdn$3.4 million). Subsequent to the nine months ending February   
29, 2008, the BEE group is in the process of increasing its shareholding from   
15% to 26% by subscribing for an additional 11% shares in the VWDG. This        
additional 11% will be at a subscription price of ZAR17.5 million and the BEE   
group will also inject ZAR10.5 million working capital into the VWDG. The BEE   
company is African Vanguard Resources (Pty) Ltd., the holding company of        
Richtrau No 136 (Pty) Ltd

(b)  Acquisition of Makoenskloof property                                       
In conjunction with the acquisition of Durnpike, HCVW had an option agreement   
to acquire the Makoenskloof alluvial diamond project. The Makoenskloof          
property is located on the north bank of the Middle Orange River ("MOR"). As    
a result of the acquisition of HCVW by Durnpike, and concurrent acquisition     
of Durnpike by Rockwell, the Company assumed the option to purchase the         
Makoenskloof property.                                                          
In November 2006, HCVW exercised its option to purchase the property and the    
company that held the mineral rights of the Makoenskloof property. HCVW paid    
ZAR5.4 million ($880,000) in January 2007 for the property and mining           
permits. Pursuant to this option exercise, HCVW also entered into a sub-        
contracting agreement with Folmink Delwery CC to perform bulk sampling          
commencing in March 2007. In April 2007 HCVW entered into an agreement to       
purchase ZAR21.3 million (approximately $3 million) in plant and equipment      
from the sub-contractor and to terminate the sub-contracting arrangement. The   
Company has paid a total consideration of ZAR19 million ($2.7 million) and is   
committed to pay the remaining consideration in monthly payments of             
ZAR500,000 ($63,000). The monthly payments shall incur interest calculated at   
the prime rate of the Standard Bank of South Africa.                            
In December 2007, Makoenskloof property was placed on care and maintenance in   
order for management to evaluate the results of the bulk sampling activities    
which had taken place up until the end of November 2007.                        
(c)  Ricardo Property, Chile                                                    
The Company holds a 100% interest in certain mineral exploration and            
exploitation concessions in the Calama Mining District in Chile. The Company    
continues to maintain the Ricardo Property in good standing.                    
(d)  Farhom Property, South Africa                                              
On July 30, 2007 H.C. Van Wyk Diamonds acquired 100% of the shares and          
shareholder loans of Farhom Mining & Construction (Pty) Ltd. for ZAR10          
million ($1.5 million).  This company holds the mineral rights over the         
Farhom farm property.  This transaction was concluded in terms of an option     
granted to HCVW on February 24, 2005 and later amended on July 10, 2007.

vesting over two years, to its directors, employees, officers, and              
consultants.  The exercise price of each option is set by the Board of          
Directors at the time of grant and cannot be less than the market price (less   
permissible discounts) on the Toronto Stock Exchange.  Options have a maximum   
term of five years and typically terminate 30 days following the termination    
of the optionee`s employment, except in the case of retirement or death.

14.  CONTINGENCIES AND COMMITMENTS                                              
(a)  One of the 50% shareholders of Midamines has, subsequent to the            
conclusion of the Midamines Agreement (see note 7(a)) in accordance with a      
mandate granted by such shareholder, denied the validity of the Midamines       
Agreement. The remaining 50% shareholder disputes this view and remains         
committed to the Midamines Agreement.  Due to this dispute, Midamines has not   
afforded Durnpike access to the site, and assistance as regards its proposed    
operations on the site, in the manner contemplated in the Midamines             
Agreement. This failure has significantly delayed the Company`s proposed        
operations on the site, and it is consequently the Company`s position that      
the required royalty payments have become suspended for the duration of         
Midamines internal dispute.                                                     
The Company remains committed to the Kwango River Project and is hopeful that   
the ongoing dispute between the shareholders of Midamines will be resolved.     
The Company will obtain formal legal advice from both Belgian and DRC legal     
counsel as soon as possible as the Midamines Agreement is governed by Belgian   
law and the obligations under the Midamines Agreement are to be implemented,    
where required, in accordance with the laws of the DRC. Concurrently, the       
Company will also monitor the resolution of the internal dispute between the    
Midamines shareholders. If the issue of minimum royalty payments is not         
settled on or before December 31, 2008, the Company will seek formal legal      
advice and may consider formally terminating the Midamines Agreement. During    
the third quarter of 2008 the Company paid consideration of $600k to            
Midamines in order to increase the size of the concession.                      
(b)  In April 2007 the Company, entered into an agreement in relation to its    
Makoenskloof property to purchase plant and equipment in the amount of          
ZAR21.3 million (approximately $3.2 million) from Folmink Delwery CC.  As at    
February 29, 2008 the Company is committed to pay the remaining consideration   
of ZAR2.3 million ($294,402) in the following manner:                           
-    The balance shall be paid in monthly payments of ZAR500,000 ($63,000).     
The monthly payments shall incur interest calculated at the prime rate of the   
Standard Bank of South Africa.                                                  
15.  SUBSEQUENT EVENTS                                                          
(a)  Acquisition of Saxendrift Mine (Pty) Ltd.                                  
On March 6, 2007, the Company and Trans Hex Group Limited ("Trans Hex")         
entered into a conditional agreement whereby the Company`s wholly owned South   
African subsidiary, Rockwell Resources RSA (Pty) Ltd. ("Rockwell RSA"), would   
acquire two open pit alluvial diamond mines and three alluvial diamond          
exploration projects from Trans Hex ("the Transaction"). Trans Hex, through     
its wholly-owned subsidiary, Trans Hex Operations (Pty) Ltd. ("THO"), is the    
owner of two open pit alluvial diamond mines, namely Saxendrift and             
Niewejaarskraal, and three alluvial diamond exploration projects, namely        
Kwartelspan, Zwemkuil-Mooidraai and Remhoogte-Holsloot, which are located       
along the southern bank of the Middle Orange River in the Northern Cape         
Province of South Africa ("Northern Cape") and which are collectively           
referred to as the Middle Orange River Operations and Projects (or "MORO").     
The MORO includes:                                                              
-    the rights to prospect, explore and/or mine precious stones and/or other   
minerals and/or metals held directly or indirectly by THO in the Saxendrift     
area of the Northern Cape;                                                      
-    a series of large remnant alluvial diamond terraces;                       
-    the material plant, machinery, equipment and other movable assets owned    
and/or used by THO;                                                             
-    certain employees of THO; and                                              
-    a rehabilitation liability which will be taken over by the Company.        
The Company has paid cash consideration to Trans Hex of ZAR100.4 million        
($14.8 million) and will assume potential liabilities for staff layoffs of      
ZAR4.7 million (capped at ZAR5 million ($0.8 million)) and rehabilitation       
bonds (capped at ZAR4.25 million ($0.6 million)). An independent consultant     
has been appointed to determine the value of the rehabilitation bonds. All      
payments and liabilities are expected to total $16.2 million, subject to        
certain final adjustments. Trans Hex will transfer all its relevant mineral     
rights and associated assets into a new special purpose entity ("Saxendrift     
Mine Pty (Ltd)"), to be acquired by Rockwell RSA. The implementation of the     
Transaction is subject to fulfillment of certain conditions precedent           
including:                                                                      
-    The unconditional approval of South Africa`s Competition Commission;       
which has already taken place;
