(f)           Mr. Butts is a citizen of the United States.

ITEM 3.        SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

On June 8, 2010, the Reporting Person, Mr. Robert W. Butts, purchased 41,504,000 units of the Issuer, which consists of 41,504,000 common shares and 41,504,000 unregistered warrants in the Issuer in a transaction more fully described in Item 5(c) below.  The units were purchased for $1,245,120.  The source of the funds was the personal funds of the Reporting Person.

ITEM 4.        PURPOSE OF TRANSACTION.

The Reporting Person did not have at the time of purchase, and do not currently have, any intention of acting with the purpose or effect of changing or influencing the control of the Issuer.
 
From time to time, however, the Reporting Person may consider the feasibility and advisability of various alternative courses of action with respect to investment in the Issuer’s securities. The Reporting Person decisions and actions with respect to such possibilities may depend upon a number of factors, including, without limitation, the actions of the Issuer with respect to potential acquisitions or business combinations, market activity in the Issuer’s securities, an evaluation of the Issuer and its prospects, general market and economic conditions, conditions specifically affecting the Reporting Person and other factors which the Reporting Person may deem relevant to their investment decisions.
 
Except as set forth in this Schedule 13D, no contract, arrangement, relationship or understanding (either oral or written) exists among the Reporting Person as to the acquisition, disposition, voting or holding of Shares.  None of the Reporting Person has any plans or proposals that relate to or would result in any of the actions described in Item 4 of Schedule 13D.

ITEM 5.        INTEREST IN SECURITIES OF THE ISSUER.

(a)  The Reporting Person beneficially owns 41,504,000 shares of Common Stock, which represents 11.3% of the Issuer’s outstanding shares of Common Stock, which such percentage was calculated by dividing (i) 41,504,000, the number of shares of Common Stock beneficially owned by the Reporting Persons by (ii) 368,294,451 shares of Common Stock, the number of shares of Common Stock issued and outstanding as reported to the Reporting Persons by the Issuer on June 9, 2010.
 
(b)  The Reporting Person has the power to vote and dispose of the 41,504,000 shares of Common Stock.
 
(c)  On June 9, 2010, the Reporting Person acting purchased 41,504,000 units. Each unit consists of one common share and one unregistered warrants.  The purchase price of each unit was CDN $0.03.   The warrants may not be exercised until October 30, 2010, and therefore, pursuant to Rule 13d-3(d)(1)(i), the reporting person is not deemed to be the beneficial owner of the Common Stock underlying the warrants at this time, and thus the shares underlying the warrants are not reported as owned by this Amendment.
 
(d)  Not applicable.
 
(e)  Not applicable.

ITEM 6.        CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS, OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER.

None.

ITEM 7.        MATERIALS TO BE FILED AS EXHIBITS.

None.
