Explanatory Note

This Amendment amends Items 1 through 7 of the Schedule 13D as set forth below. Except as specifically amended by this Amendment, each Item of the Schedule 13D remains unchanged. All capitalized terms contained herein but not otherwise defined shall have the meanings ascribed to such terms in the Schedule 13D.

The primary purposes of amending the Schedule 13D are to report the Transaction and the Voting Agreement and other agreements related thereto (each as defined below) and to report changes among the Reporting Persons as a result of a reorganization of La Mancha Holding S.à r.l. (“LMH”) and the delegation of voting and dispositive discretion over the Issuer Common Stock.

The information set forth in Item 5 of this Amendment is incorporated herein by reference.

ITEM 4. PURPOSE OF TRANSACTION

Item 4 of the Schedule 13D is hereby amended and supplemented as follows:

Arrangement Agreement

On October 31, 2021, Chifeng Jilong Gold Mining Co., Ltd., a corporation existing under the laws of the People’s Republic of China (the “Parent”), Chijin International (Hong Kong) Limited, a corporation existing under the laws of the People’s Republic of China (the “Purchaser”) and the Issuer, entered into a definitive Arrangement Agreement, as amended by an amending agreement dated November 24, 2021 and an assignment and assumption agreement dated December 21, 2021 (the “Arrangement Agreement”), pursuant to which the Purchaser agreed to acquire all of the issued and outstanding Issuer Common Stock by way of a statutory plan of arrangement (“Plan of Arrangement”) under the Canada Business Corporations Act (the “Transaction”).

Pursuant to the Transaction, holders of the Issuer Common Stock (“Golden Star Shareholders”) received total consideration, paid in cash, of US$3.91 (equivalent to approximately C$4.85) per share of the Issuer Common Stock, which equates to approximately US$470 million on a fully-diluted, in-the-money basis.

The Voting Agreement

All directors and officers of the Issuer, as well as LMSI, which, based on information reported by the Issuer, collectively held at the time of execution of the Voting Agreement (as defined below) approximately 33.4% of the Issuer Common Stock, entered into voting support agreements with Chifeng pursuant to which they agreed to, among other things, vote in favor of the shareholder resolution approving the Transaction.

On October 31, 2021, in connection with the execution and delivery of the Arrangement Agreement, LMSI, the Parent and the Purchaser entered into a voting and support agreement (the “Voting Agreement”), pursuant to which, among other things, LMSI generally agreed to cause to be counted as present for purposes of establishing quorum and to vote (or cause to be voted) all of the shares of the Issuer Common Stock that they owned (to the extent they carry a right to vote): (i) at any meeting of any of the securityholders of the Company at which LMSI or any registered or beneficial owner of the Issuer Common Stock are entitled to vote in favor of the approval of the Transactions (and any transactions contemplated in connection with the Arrangement Agreement); or (ii) in any action by written consent of the securityholders of the Company, in favor of the approval, consent, ratification and adoption of any resolution approving the Transactions (and any transactions contemplated in connection with the Arrangement Agreement). Further, LMSI agreed not to transfer or pledge the shares of the Issuer Common Stock that it owned.

The purpose of the Voting Agreement was to facilitate the consummation of the Transaction.

The Issuer announced on January 7, 2022 that it had obtained a final order from the Ontario Superior Court of Justice (Commercial List) approving the Issuer’s Plan of Arrangement and that the Transaction was approved at a special meeting of the Golden Star Shareholders held on December 30, 2021. The Transaction was consummated on the Closing Date.

The information contained in each of Item 3 and Item 5 of this Amendment is incorporated herein by reference.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER

Item 5 of the Schedule 13D is hereby amended by amending and restating captions (a), (c) and (e) thereof to read as follows:

(a)

Prior to the consummation of the Transaction, LMSI was the beneficial owner of 38,389,704 shares of the Issuer Common Stock, or approximately 33.2% of the Issuer Common Stock issued and outstanding (on a non-diluted basis).

LMI, as the sole shareholder of LMSI, may have been deemed to have voting and dispositive power with respect to the shares of the Issuer Common Stock beneficially owned by LMSI. As such, LMI may have been deemed the indirect beneficial owner of 38,389,704 shares of the Issuer Common Stock, or approximately 33.2% of the Issuer Common Stock issued and outstanding (on a non-diluted basis).

LMF, as the sole shareholder of LMI, may have been deemed to have voting and dispositive power with respect to the shares of the Issuer Common Stock beneficially owned by LMSI. As such, LMF may have been deemed the indirect beneficial owner of 38,389,704 shares of the Issuer Common Stock, or approximately 33.2% of the Issuer Common Stock issued and outstanding (on a non-diluted basis).

NSPE has been appointed as alternative investment fund manager (“AIFM”) and is exclusively responsible for managing LMF in accordance with the Alternative Investment Fund Managers Directive. NSPE has sub-delegated authority to G10, who together with NSPE are responsible for the day-to-day management of LMF’s portfolio relating to the Issuer Common Stock as investment manager and investment advisor, respectively. NSPE and G10 may have been deemed as a result of such delegation to have voting and dispositive power with respect to the shares of the Issuer Common Stock beneficially owned by LMSI. As such, each of G10 and NSPE may have been deemed the indirect beneficial owners of 38,389,704 shares of the Issuer Common Stock, or approximately 33.2% of the Issuer Common Stock issued and outstanding (on a non-diluted basis).

Each of the Reporting Persons disclaims beneficial ownership in all shares of the Issuer Common Stock reported herein, except to the extent of the Reporting Person’s respective pecuniary interest therein. All share percentage calculations in this Amendment are based on 115,725,047 shares of the Issuer Common Stock issued and outstanding as of November 1, 2021, as reported under the section “Outstanding Share Data” in the Issuer’s Management’s Discussion and Analysis for the three and nine months ended September 30, 2021, included as Exhibit 99.1 to the Issuer’s Form 6-K filed with the U.S. Securities and Exchange Commission on November 1, 2021.

Upon signing of the Voting Agreement, the Purchaser and the Parent may have been deemed to have shared beneficial ownership with respect to the 38,389,704 shares of the Issuer Common Stock, or approximately 33.2% of the Issuer Common Stock issued and outstanding (on a non-diluted basis). Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission that the Purchaser or the Parent are the beneficial owners of the relevant shares for purposes of Section 13(d) of the Act, or for any other purpose, and such beneficial ownership is expressly disclaimed.

Following the consummation of the Transaction, the Reporting Persons are no longer beneficial owners of any shares of Issuer Common Stock. Items 7 through 13 of each of the cover pages of this Statement are incorporated herein by reference.

(c)

On December 17, 2021, LMSI acquired beneficial ownership of an aggregate of 50,000 shares of the Issuer Common Stock in the 2021 Covered Trades at an average price per share of $3.6713, for a total purchase price equal to $183,565.

On the Closing Date, pursuant to the Transaction, LMSI sold 38,389,704 shares to the Purchaser at a weighted average price of US$3.91 per share of the Issuer Common Stock.

Other than as described in this Amendment and the Schedule 13D, the Reporting Persons and, to the Reporting Persons’ knowledge, the Covered Individuals, have not effected any transactions in the Issuer Common Stock during the last 60 days.

(e)

Each of the Reporting Persons ceased to be the beneficial owner of any of the Issuer Common Stock as of the Closing Date. The information contained in each of Items 3 and 5 of this Amendment is incorporated herein by reference.

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

The information set forth in Item 4 of this Schedule 13D is incorporated into this Item 6 by reference.

The section titled “Loan Facility” in Item 6 of the Schedule 13D is hereby amended and supplemented as follows:

The 2021 Facility Agreement will be amended to provide for a release of the Issuer Common Stock on the closing of the Transaction.

Other than as described in Item 4, to the knowledge of the Reporting Persons, there are no contracts, arrangements, understandings or relationships (legal or otherwise) between the persons named in Item 2 and any other person with respect to any 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, including any securities pledged or otherwise subject to a contingency the occurrence of which would give another person voting power or investment power over such securities.

ITEM 7. MATERIALS TO BE FILED AS EXHIBITS

Item 7 of the Schedule 13D is hereby amended and supplemented by inserting the following:

14	Joint Filing Agreement, dated February 2, 2022, between LMSI, LMI, LMF, NSPE and G10.
