Golden Star Announces Filing of Audited H1 2021 Financial Statements

TORONTO, Dec. 9, 2021 /CNW/ - Golden Star Resources Ltd. (NYSE American: GSS) (TSX: GSC) (GSE: GSR) ("Golden Star" or the "Company") has filed audited consolidated financial statements for the six months ended June 30, 2021 (the "Audited H1 2021 Financial Statements") which are required by the Shanghai Stock Exchange in respect of Chifeng Jilong Gold Mining Co., Ltd. (SHSE: 600988) ("Chifeng") seeking to obtain the requisite approvals in connection with the Company's previously announced plan of arrangement under Section 192 of the Canada Business Corporations Act (the "Transaction"), involving the Company, Chifeng and its subsidiary Chijin International (Hong Kong) Limited (the "Purchaser") and/or an assignee of the Purchaser, pursuant to the arrangement agreement dated October 31, 2021 (as amended, the "Arrangement Agreement").

The Company previously filed unaudited interim consolidated financial statements for the three and six months ended June 30, 2021, (the "Unaudited H1 2021 Financial Statements") on July 28, 2021 in accordance with, and as required by, applicable securities laws.

The Audited H1 2021 Financial Statements were prepared in accordance with the full set of International Financial Reporting Standards, as issued by the International Accounting Standards Board ("IFRS") and the interpretations of the International Financial Reporting Interpretations Committee which the Canadian Accounting Standards Board has approved for incorporation into Part 1 of the CPA Canada Handbook – Accounting, whereas, the Unaudited H1 2021 Financial Statements, although also prepared in accordance with IFRS, applied IAS 34 "Interim Financial Reporting" (IAS 34).

The Audited H1 2021 Financial Statements are substantially consistent with the Unaudited H1 2021 Financial Statements and the only significant measurement difference arises from the income tax calculations prepared under IAS 12 "Income Taxes" for the Audited H1 2021 Financial Statements and under IAS 34 for the Unaudited H1 2021 Financial Statements. The effect is an increase in current tax expense of US$2.1 million with a corresponding increase in current income tax liabilities of US$2.1 million and a decrease in deferred tax expense of US$2.1 million with a corresponding decrease in deferred tax liability of US$2.1 million. There is no impact to the consolidated statement of cash flows for the six months ended June 30, 2021.

Readers must not place any reliance on the Audited H1 2021 Financial Statements as they have been prepared specifically for the purpose of the Transaction and not for the purpose of satisfying applicable securities laws requirements. Accordingly, readers must rely solely on the Unaudited H1 2021 Financial Statements which were prepared for the purpose of satisfying the Company's reporting requirements under applicable securities laws.

The Transaction

Pursuant to the Arrangement Agreement, Chifeng, through the Purchaser and/or its assignee, has agreed to acquire all of the issued and outstanding common shares of the Company. Pursuant to and upon completion of the Transaction, shareholders of the Company will receive total consideration, payable in cash, of US$3.91 (equivalent to approximately C$4.85 as of October 31, 2021) per common share of the Company (the "Consideration"), which equates to a total Transaction value of approximately US$470 million on a fully-diluted, in-the-money basis.

Advisors

Golden Star has engaged Canaccord Genuity Corp. as its exclusive financial advisor as well as Fasken Martineau DuMoulin LLP and Davis Graham & Stubbs LLP as its respective Canadian and United States legal advisors. Canaccord Genuity Corp. provided a fairness opinion to Golden Star's Board of Directors.

These dates may change for a number of reasons, including the inability to secure necessary approvals in the time assumed or the need for additional time to satisfy the other conditions to the completion of the Transaction. Accordingly, you should not place undue reliance on the forward-looking statements and information contained in this news release concerning these times.

Forward-looking statements are based on the opinions and estimates of management as of the date such statements are made and involve known and unknown risks, uncertainties and other important factors that may cause the actual results, performance or achievements of Golden Star to be materially different from those expressed or implied by such forward-looking statements.

Although Golden Star has attempted to identify important factors that could cause actual results to differ materially from those contained in forward-looking statements, there may be other factors that cause results not to be as anticipated, estimated or intended. There can be no assurance that future developments affecting the Company will be those anticipated by management. Please refer to the discussion of these and other factors in Management's Discussion and Analysis of financial condition and results of operations for the year ended December 31, 2020 and in our annual information form for the year ended December 31, 2020 as filed on SEDAR at www.sedar.com. The forecasts contained in this press release constitute management's current estimates, as of the date of this press release, with respect to the matters covered thereby. We expect that these estimates will change as new information is received. While we may elect to update these estimates at any time, we do not undertake any estimate at any particular time or in response to any particular event, except as may be required by applicable securities laws. Investors are cautioned that forward-looking statements are not guarantees of future performance and accordingly investors are cautioned not to put undue reliance on forward-looking statements due to their inherent uncertainty.
