GOLDEN STAR REPORTS FINANCIAL RESULTS FOR FOURTH QUARTER

AND YEAR-END 2007

Denver, Colorado, February 27, 2008: Golden Star Resources Ltd. (AMEX: GSS; TSX: GSC; GSE: GSR) today announced its audited year-end results for 2007 and unaudited fourth quarter results. All currency in this news release is expressed in U.S. dollars, unless otherwise noted. The Company will host a live webcast and conference call, to discuss its quarterly results on Thursday, February 28, at 11:00 a.m. ET. To access the webcast and conference call, go to the home page of the Company’s website, www.gsr.com.

Tom Mair, Interim President and CEO, said, “We achieved record gold production in the full year and the fourth quarter despite a number of issues, including some beyond our control. We expect ongoing optimization of the Bogoso sulfide processing plant to contribute to improved bottom line results going forward. Many of the challenges that we faced in 2007, including the country-wide power restrictions in Ghana, appear to be behind us and we are looking forward to a consistently improving 2008.”

Mr. Mair also commented that, “As disclosed in a separate press release, year-on-year Mineral Reserves increased 19% in 2007, primarily as the result of a positive feasibility study on the HBB properties; Mineral Reserves at Bogoso/Prestea increased year-on-year more than replacing depletion, and a partial replacement of rising depletion was also achieved at our Wassa mine.”

2007 RESULTS AND HIGHLIGHTS

FOURTH QUARTER 2007 RESULTS AND HIGHLIGHTS

OVERVIEW

We had a net loss of $36.4 million or $0.159 per share, on revenues of $175.6 million for 2007 compared to net income of $64.7 million or $0.312 per share on revenues of $122.6 million for 2006. The net loss for 2007 was impacted by gains on sale of assets as well as by a tax valuation allowance and a loss on debt retirement as shown in the following table.

Mine operating margin losses totaled $14.3 million in 2007, down from a $7.6 million positive operating margin in 2006. The primary operating factor influencing the 2007 results occurred in the second half of 2007 when the Bogoso sulfide processing plant was placed in service and its operating costs were recognized. Gold recovery difficulties associated with the start-up of the plant resulted in lower than anticipated revenues leading to a negative operating margin. In addition, there were

industry-wide increases in the costs of labor, reagents, fuel and power that contributed to the lower margin in 2007 compared to 2006.

A $22.9 million tax valuation allowance was taken in the fourth quarter against future tax assets. While this reduced the year-end tax benefit by $22.9 million, all $22.9 million of the benefit remains available for future use. Looking forward, we anticipate gold sales for 2008 of between 370,000 and 425,000 ounces at a cash operating cost between $490 and $540 per ounce.

FINANCIAL SUMMARY

BOGOSO/PRESTEA

An operating margin loss of $23.9 million was incurred at Bogoso/Prestea during 2007 versus a positive operating margin of $8.4 million in 2006. The loss was primarily due to lower ore grades and insufficient oxide ore and partially due to delays in obtaining permits for the Pampe pit and to problems in the sulfide plant start-up in the second half of 2007.

Total cash operating costs for the combined oxide and sulfide operations at Bogoso/Prestea were $94.7 million compared to $44.7 million in 2006. The majority of this increase is attributable to the new sulfide processing plant operations that went into commercial production on July 1, 2007.

WASSA

Wassa generated an operating margin of $9.6 million in 2007 compared to an operating margin loss of $0.8 million for 2006. The improved operating margin was primarily due to higher gold production resulting from a higher gold grade and higher gold prices.

HBB PROPERTIES

Construction on the 52 kilometer haul road linking the Benso property to the Wassa processing plant commenced in October 2007. The deposits at the Hwini-Butre and Benso properties will be mined as satellite deposits to provide high grade ore to the Wassa processing facility. We anticipate the first ore mined from the Benso property will be delivered to the Wassa processing plant in the third quarter of 2008. Construction of the road extension to the Hwini-Butre deposits is expected to continue in 2009 with the first high grade ore from Hwini-Butre expected to be mined and delivered to the Wassa processing plant in 2009.

EXPLORATION

A total of $13.9 million was spent on exploration expenditures during 2007, down from $15.3 million in 2006. As is our practice, the focus of our exploration activities centered on projects in near proximity to our operating mines. In support of this strategy, an airborne geophysical survey was flown by helicopter over our project areas along the Ashanti Trend. We anticipate drilling identified targets in 2008.

Exploration in Ghana in 2007 focused on drilling programs at Wassa, Prestea South and the HBB properties. We have had encouraging results during the year and a number of these targets merit follow-up work in 2008.

At our Newmont-funded joint venture on the Saramacca project in Suriname, we received encouraging results from the exploration efforts to date. Newmont has approved exploration expenditures of $3.5 million for continued exploration on Saramacca in 2008.

CASH AND CASH FLOW

Our cash, cash equivalents and short term investments totaled $75.8 million at the end of 2007, up from $27.1 million at the end of 2006. Operations provided $6.7 million in 2007, compared to $5.4 million for 2006. A $12.2 million increase in payables was offset by an inventory increase of $11.6 million.

A total of $13.1 million was received from transactions related to EURO Ressources SA including sales of EURO shares, sale of our residual royalty in the Rosebel mine to EURO and the receipt of the final installment on their purchase of the Rosebel royalty.

Liquidity Outlook

We anticipate that all of our cash needs in 2008 will be met by the $75.8 million cash on hand at year end, amounts available from our Caterpillar equipment financing facility, the Ghana Stock Exchange listing proceeds and cash generated from operations.

GHANA POWER RESTRICTIONS

The past year was a drought year in Ghana and nation-wide power restrictions were in place until October 2007. In an effort to reduce our dependency on power from the national grid, Golden Star, along with three other mining companies, constructed a nominal 100 megawatt power plant in Ghana. In addition, we entered into a take-or-pay agreement with a power provider who will construct a 20 megawatt power station at the Bogoso site. Should electrical power once again become scarce, we anticipate that we would be able to self generate enough power to meet all our needs.

LOOKING AHEAD

Our objectives for 2008 include:

We are estimating 2008 total gold production of 370,000 to 425,000 ounces at an average cash operating cost between $490 and $540 per ounce.

Statements Regarding Forward-Looking Information: Some statements contained in this news release are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 and other applicable securities laws. Investors are cautioned that forward-looking statements are inherently uncertain and involve risks and uncertainties that could cause actual results to differ materially. Such statements include comments regarding the

availability of power, our alternative power supplies and ability to meet our power needs in the event of future power rationing, our 2008 production and cash operating cost estimates, capital expenditure estimates, planned exploration spending and activities, higher ore grades at Wassa, anticipated higher recoveries anticipated at various sites, expected improvements to the flotation circuit at the new Bogoso sulfide processing plant, the timing of achieving design recovery rates at the Bogoso sulfide processing plant, the impact of the Hwini-Butre and Benso deposits on the Wassa mine, anticipated commencement dates of mining and production and development costs with respect to the Hwini-Butre and Benso properties, plans for exploration, sources of and adequacy of cash to meet capital and other needs in 2008. Factors that could cause actual results to differ materially include timing of and unexpected events at the Bogoso/Prestea oxide and sulfide processing plant; variations in ore grade, tonnes mined, crushed or milled; variations in relative amounts of refractory, non-refractory and transition ores; delay or failure to receive board or government approvals and permits; the availability of electrical power, timing and availability of external financing on acceptable terms; technical, permitting, mining or processing issues, changes in U.S. and Canadian securities markets, and fluctuations in gold price and costs. 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 our Form 10-K for 2007, as amended. 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 and that actual results will vary from these estimates, possibly by material amounts. While we may elect to update these estimates at any time, we do not undertake to update any estimate at any particular time or in response to any particular event. Investors and others should not assume that any forecasts in this press release represent management’s estimate as of any date other than the date of this press release.

Non-GAAP Financial Measures: In this news release, we use the terms “total cash cost per ounce” and “cash operating cost per ounce.” Total cash cost per ounce is equal to total production costs less depreciation, depletion, amortization and asset retirement obligation accretion divided by the number of ounces of gold sold during the period. Cash operating cost per ounce is equal to total cash costs less production royalties and production taxes, divided by the number of ounces of gold sold during the period. We use total cash cost per ounce and cash operating cost per ounce as key operating indicators. We monitor these measures monthly, comparing each month’s values to prior period’s values to detect trends that may indicate increases or decreases in operating efficiencies. These measures are also compared against budget to alert management to trends that may cause actual results to deviate from planned operational results. We provide these measures to our investors to allow them to also monitor operational efficiencies of our mines. We calculate these measures for both individual operating units and on a consolidated basis. Total cash cost per ounce and cash operating cost per ounce should be considered as Non-GAAP Financial Measures as defined in SEC Regulation S-K Item 10 and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. There are material limitations associated with the use of such non-GAAP measures. Since these measures do not incorporate revenues, changes in working capital and non-operating cash costs, they are not necessarily indicative of operating profit or cash flow from operations as determined under GAAP. Changes in numerous factors including, but not limited to, mining rates, milling rates, gold grade, gold recovery, and the costs of labor, consumables and mine site general and administrative activities can cause these measures to increase or decrease. We believe that these measures are the same or similar to the measures of other gold mining companies, but may not be comparable to similarly titled measures in every instance.
