Item 3. Source and Amount of Funds or Other Considerations

On July 27, 2017, Discovery Key Investments purchased 279,800 Common Shares of the Issuer in the open market at an average price of CAD$22.52 per share for an aggregate purchase price of CAD$6,301,348, all of which was funded through working capital of Discovery Key Investments.

On July 28, 2017, Discovery Key Investments purchased 142,800 Common Shares of the Issuer in the open market at an average price of CAD$22.49 per share for an aggregate purchase price of CAD$3,211,472, all of which was funded through working capital of Discovery Key Investments.

On September 14, 2017, Discovery Key Investments purchased 119,700 Common Shares of the Issuer in the open market at an average price of CAD$21.27 per share for an aggregate purchase price of CAD$2,545,468, all of which was funded through working capital of Discovery Key Investments.

The Reporting Persons pledged an aggregate of 19,135,500 Common Shares of the Issuer (representing approximately 13.06% of the Issuer's issued and outstanding Common Shares as at May 10, 2017) to Equities First Holdings, LLC, a Delaware limited liability company ("Equities First") pursuant to a Master Loan Agreement and Master Pledge Agreement (together, the "Equities First Loan Documents"), dated May 12, 2017 (in relation to both the Master Loan Agreement and Master Pledge Agreement between Discovery Key Investments and Equities First) and June 12, 2017 (in relation to both the Master Loan Agreement and Master Pledge Agreement between Uptrend and Equities First). From May 12, 2017 to June 12, 2017, an aggregate of 7,200,000 Common Shares were pledged by Discovery Key Investments, and from June 20, 2017 to July 25, 2017, an aggregate of 11,935,500 Common Shares were pledged by Uptrend. The Reporting Persons recently learned that Equities First considered that ownership of, and title to, the pledged shares were transferred to Equities First upon their pledge, and that the pledged shares would only be transferred back to the Reporting Persons when and if the loan has been fully repaid. The Reporting Persons have now determined in good faith, with the benefit of legal advice, that there was in fact a transfer of the title and ownership of the pledged shares to Equities First upon their pledge to Equities First. The 1,800,000 Common Shares pledged by the Reporting Persons on May 12, 2017 represented approximately 1.23% of the 146,496,265 Common Shares reported by the Issuer as issued and outstanding as of May 10, 2017 in its Management's Discussion and Analysis for the three months ended March 31, 2017.

On August 10, 2017, the Reporting Persons pledged an aggregate of 7,200,000 Common Shares of the Issuer (representing approximately 4.91% of the Issuer's issued and outstanding as at May 10, 2017) to Fullerton Capital Limited ("Fullerton") pursuant to a Stock Secured Financing Agreement and a Control Agreement dated August 10, 2017 (the "Fullerton Loan Documents"). On or about July 12, 2019, the Reporting Persons learned that Fullerton had wrongfully sold the pledged shares to what appears to be one or more arms length third party purchasers during the period August 31, 2017 to September 6, 2017. Pursuant to the Fullerton Loan Documents, voting investment power of the pledged shares would not pass to the pledgee until such time as there has been a default thereunder. Although the Reporting Persons and Fullerton dispute whether such a default has occurred, the Reporting Persons acknowledge that, due to Fullerton's disposal of the pledged shares, the pledged shares are no longer owned or controlled by the Reporting Persons.

Item 4. Purpose of Transaction

Item 4 of the Original Schedule 13D is hereby amended and supplemented by adding the following at the end thereof:

Discovery Key Investments' purchases of 542,300 Common Shares of the Issuer on July 27, 2017, July 28, 2017 and September 14, 2017 were for investment purposes.

As disclosed in more detail under Item 3 above, the following transactions have resulted in a reduction in the number of Common Shares beneficially owned by the Reporting Persons:

• Between May 12, 2017 and July 25, 2017, pursuant to the Equities First Loan Documents, the Reporting Persons pledged an aggregate of 19,135,500 Common Shares of the Issuer to Equities First as a security of a loan.  The Reporting Persons recently learned that Equities First considered that ownership of, and title to, the pledged shares were transferred to Equities First at the time the Equities First Loan Documents were executed.  The Reporting Persons, having had the benefit of legal advice, now accept Equities First's position.

• Pursuant to the Fullerton Loan Documents, the Reporting Persons pledged an aggregate of 7,200,000 Common Shares of the Issuer to Fullerton as collateral for a loan. The pledged shares were subsequently sold by Fullerton in or about September 2017 to what appears to be one or more arm's length third parties, and are no longer owned or controlled by the Reporting Persons. The Reporting Persons believe that such sale was made by Fullerton in contravention of the Fullerton Loan Documents.

Except as otherwise disclosed herein, the Reporting Persons have no current plans or proposals that relate to or would result in:

(a) the acquisition by any person of additional securities of the Issuer, or the disposition of securities of the Issuer;

(b) any extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Issuer or any of its subsidiaries;

(c) a sale or transfer of a material amount of the assets of the Issuer or any of its subsidiaries;

(e) any material change in the present capitalization or dividend policy of the Issuer;

(f) any other material change in the Issuer's business or corporate structure including, but not limited to, if the Issuer is a registered closed-end investment company, any plans or proposals to make any changes in its investment policy for which a vote is required by Section 13 of the United States Investment Company Act of 1940;

(g) changes in the Issuer's charter, bylaws or instruments corresponding thereto or other actions which may impede acquisition of control of the Issuer by any person;

(h) causing a class of securities of the Issuer to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association;

(i) a class of equity securities of the Issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Act; or

(j) any action similar to any of those enumerated above.

Item 5. Interest in Securities of the Issuer

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

Pursuant to the terms of the Equities First Loan Documents described under Item 3 above, the Reporting Persons pledged an aggregate of 19,135,500 Common Shares of the Issuer to Equities First as a security of a loan.

Pursuant to the terms of the Fullerton Loan Documents described under Item 3 above, the Reporting Persons pledged an aggregate of 7,200,000 Common Shares of the Issuer to Fullerton as collateral for a loan. 

Discovery Key Investments entered into a Nominee Agreement with the Issuer in January 2018 which provides Discovery Key Investments with the right ("the Nominee Right") to appoint an observer on the board of directors of the Issuer (the "Board"), which will evolve into a right to appoint a director to the Board if certain conditions are met. The Nominee Right will terminate once the Discovery Key Investments' ownership drops below an agreed threshold of 10% of the Issuer's issued and outstanding.

Except as disclosed herein, the Reporting Persons do not have any contract, arrangement, understanding or relationship with respect to securities of the Issuer including, but not limited to, transfer or voting of any of the securities, finder's fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies, the Reporting Person have not pledged securities of the Issuer nor are the securities of the Issuer held by the Reporting Persons subject to a contingency, the occurrence of which would give another person voting power or investment power over such securities.
