Golden Star Resources Contemplates Exchanging Its Existing Convertible Debentures for New Convertible Debentures

DENVER, CO, May 17, 2012 (MARKETWIRE via COMTEX) --Golden Star Resources Ltd. (NYSE MKT: GSS) (NYSE Amex: GSS) (TSX: GSC) (GHANA: GSR) ("Golden Star" or the "Company") today announced its intention to exchange certain of its 4.00% Convertible Senior Unsecured Debentures due November 30, 2012 (the "Original Debentures") for new Convertible Senior Unsecured Debentures (the "New Debentures") via privately negotiated exchange agreements with certain holders of the Original Debentures.

The New Debentures would carry a 5.00% coupon and would mature on June 1, 2017. Each New Debenture would be, subject to certain limitations, convertible into common shares at a conversion rate of 606.0606 common shares per $1,000 principal amount of New Debentures (equal to an initial conversion price of $1.65 per share). The New Debentures would not be redeemable at the Company's option, except in the event of certain change in control transactions where 90% or more of the outstanding New Debentures have accepted a mandatory offer to purchase by the Company.

The New Debentures would be direct senior unsecured indebtedness of the Company, ranking equally and ratably with all other senior unsecured indebtedness and senior to all subordinated indebtedness. None of the Company's subsidiaries would guarantee the New Debentures, and the New Debentures would not limit the amount of debt that the Company or its subsidiaries may incur. The Company intends to issue the New Debentures in transactions exempt from the registration requirements of the U.S. Securities Act of 1933, as amended (the "Securities Act").

This announcement does not constitute an offer to sell, nor is it a solicitation of an offer to buy, securities. If The Company is able to enter into the privately negotiated exchanges, the New Debentures, and the common shares issuable upon conversion of the New Debentures, would not be registered under the Securities Act or the securities laws of any other jurisdiction, and may not be offered or sold in the United States without registration under, or an applicable exemption from, the registration requirements of the Securities Act.
