Golden Star Announces Closing of Public Offering of Common Shares, including Full Exercise of Underwriters' Over-Allotment Option, and Closing of Private Placement of 7% Convertible Senior Notes due 2021

TORONTO, Aug. 3, 2016 /CNW/ - Golden Star Resources Ltd. (NYSE MKT: GSS; TSX: GSC; GSE: GSR) ("Golden Star" or the "Company") announces the closing of its previously announced underwritten public offering of common shares at a price of US$0.75 per share. The underwriters for the offering exercised in full their option to purchase an additional 6,000,000 common shares. As a result, a total of 46,000,000 common shares were sold by the Company for gross proceeds of US$34.5 million.

The Company also announces the closing of its previously announced private placement of US$65.0 million aggregate principal amount of 7.0% convertible senior notes due 2021. As part of the offering of convertible senior notes, the Company exchanged US$42.0 million principal amount of its outstanding 5.0% convertible senior unsecured debentures due June 1, 2017 for an equal principal amount of newly issued convertible senior notes. The principal amount exchanged is included in the total aggregate principal amount of senior convertible notes issued. The Company did not receive any cash proceeds from the exchange.

The Company intends to use the net cash proceeds from the offering of common shares of approximately US$32.4 million, together with the net cash proceeds from the private placement of convertible senior notes of approximately US$21.2 million, to strengthen its balance sheet by retiring certain of its outstanding indebtedness, including through the repurchase of additional 5.0% convertible senior unsecured debentures due June 1, 2017 in privately negotiated transactions, repayment of its secured medium term loan facility with Ecobank Ghana Limited, and to use any remaining funds for general corporate purposes.

André van Niekerk, Executive Vice President and Chief Financial Officer of Golden Star, commented:

"The closing of the two offerings represents an important milestone in Golden Star's transformation into a lower cost gold producer. With these transactions we reduced our debt, strengthened our balance sheet and unlocked a robust financial future for our shareholders. We expect strong cash flow in the coming years through our expanding gold production and anticipate further cost reductions, further solidifying Golden Star's financial position.  With the first stopes blasted at Wassa Underground in early July 2016 and the balance sheet improved, we now look forward to the next key milestone in our transformation: the commencement of production from the high grade Prestea Underground Gold Mine in mid-2017."

The offering of common shares was made through an underwriting group led by BMO Capital Markets as sole book-running manager, which included National Bank Financial Inc., Scotia Capital Inc. and CIBC Worlds Markets Inc. The common shares were sold pursuant to an effective registration statement, including a base shelf prospectus and supplement, that has been filed with the U.S. Securities and Exchange Commission, and a base shelf prospectus and supplement that that has been filed with applicable Canadian securities regulators.

In connection with the offerings, the Company has relied on the exemption set forth in Section 602.1 of the TSX Company Manual, which provides that the TSX will not apply its standards to certain transactions involving eligible interlisted issuers.
