GOLDEN STAR REPORTS FOURTH QUARTER AND YEAR-END 2010 FINANCIAL RESULTS

Denver, CO—February 23, 2011—Golden Star Resources Ltd. (NYSE Amex: GSS; TSX: GSC; GSE: GSR) (“Golden Star” or the “Company”) today announced its audited year-end results for 2010 and unaudited fourth quarter 2010 results. All currency in this news release is expressed in U.S. dollars. The Company will host a live webcast and conference call to discuss its quarterly results on Thursday, February 24, 2011 at 11:00 a.m. Eastern Time (9:00 a.m. Mountain Time). To access the webcast and conference call, go to the home page of the Company’s website, www.gsr.com.

Tom Mair, President and CEO, said, “Production at Bogoso during the second half of the year was adversely constrained by the need to process transitional ores with lower recoveries. As mining progresses through the transition ore to access the fresh sulfide ores with higher recovery rates, we anticipate increased production and lower cash operating costs. We also expect to commission the Bogoso tailings retreatment facility during 2011 as a source of low-cost incremental gold production.”

2010 RESULTS

FINANCIAL SUMMARY

BOGOSO/PRESTEA

Gold sales from Bogoso/Prestea totaled 170,973 ounces during 2010. Fourth quarter gold sales from Bogoso/Prestea were 28,021 ounces of gold. Factors that affected gold production during the second half of 2010 included lower recovery rates due to the mix of transitional ore being supplied to the sulfide processing plant and poor weather conditions. A limited volume of oxide ore was provided to the oxide processing plant during the fourth quarter of 2010. During 2011, we expect to commission the tailings retreatment facility and increase the utilization of the oxide processing plant.

As mining progresses deeper into Chujah and the Bogoso North pits, we anticipate increasing amounts of fresh sulfide ore, higher recovery rates and, consequently, higher gold production.

WASSA/HBB

Wassa performed as expected in 2010 with fourth quarter gold sales of 48,895 ounces and 183,931 ounces for the full year. In 2011, we anticipate production of 170,000 – 180,000 ounces of gold at a cash operating cost range of $650 - $700 per ounce.

LIQUIDITY AND CAPITAL RESOURCES

Our cash and cash equivalents at year-end 2010 were $178.0 million, up $23.9 million over the prior year. The increase in cash was related to $115.2 million of cash from operating activities offset by $83.8 million of capital investments and net reduction of $12.4 million of debt.

Capital spending amounted to $83.8 million for 2010. This included $20.9 million for mine development projects, $30.9 million for capital equipment purchases, $15.1 million for deferred stripping, and $16.9 million for mine site and exploration drilling.

Along with our cash position, we hold a $42 million revolving credit facility and have an additional $19 million of borrowing capacity under our equipment financing credit facility. We expect to use approximately $100 million for capital projects in 2011. This total includes $42 million for new equipment and facilities upgrades, $20 million for mine-site drilling, and $38 million for mine property development.

DEVELOPMENT PROJECTS

The Bogoso Tailings Retreatment project is on track to be operational, subject to permitting, in the second half of 2011. The engineering has been completed and permitting and equipment procurement commenced in the fourth quarter of 2010 to build a hydraulic tailings recovery system to pump tailings to the oxide processing plant. This will be a low-cost incremental source of gold production for Bogoso/Prestea.

During 2011, we will continue working on permitting the Mampon and Prestea South deposits and will proceed with the Pampe pit layback. These deposits will provide additional sources of ore for the Bogoso oxide processing plant.

We are also completing our evaluation of the Prestea Underground Project. We have been refurbishing the Central and Bondaye shafts at Prestea, have dewatered the mine to 30 Level and have drilled more than 64,000 m of diamond core resulting in an Indicated Mineral resource of 1.1 million tonnes grading 15.80 g/t, with significant potential to expand along strike and at depth.

EXPLORATION

In 2010, a total of $20 million was spent on exploration projects of which 80% was spent on mine site drilling. This resulted in a 24% increase in Mineral Reserves and a 63% increase in Mineral Resources. These results are discussed in more detail in a separate press release dated February 23, 2011.

The exploration budget for 2011 is $30 million and these funds will also be focused on resource definition drilling surrounding our operating areas in Ghana as well as very selective exploration and drilling at our other West African projects, and an increased level of exploration activity in Brazil.

In Brazil, we signed a joint venture agreement with Votorantim Metais, a subsidiary of Votorantim Group, a large Brazilian conglomerate. The joint venture covers a 3,400 square kilometer land package in northern Mato Grosso state, Brazil. We will also be exploring on our other Brazilian projects in Mato Grosso, Goias and Minas Gerais states.

LOOKING AHEAD

Our objectives for 2011 include:

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 permitting and the mining at Prestea South; our 2011 exploration budget and planned exploration activities and drilling, including exploration at Bogoso/Prestea, and Wassa/HBB, and in West Africa and Brazil; the ability to fund cash needs including capital and operating expenditures; optimization of throughput and recovery rates at the Bogoso sulfide processing plant, including the nature of ore that is expected to be encountered at Bogoso/Prestea and its impact on recovery rates and production levels; our 2011 production and cash operating cost estimates, capital expenditure estimates, our objectives for 2011; the timing of a development decision in respect of Prestea Underground; sources of and adequacy of cash to meet capital and other needs in 2010; and the ability to convert Mineral Resources into Mineral Reserves. 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 and cost 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 and general economic conditions. 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 2010. 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 “cash operating cost per ounce.” 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 cash operating cost per ounce as a key operating indicator. We monitor this measure monthly, comparing each month’s values to prior period’s values to detect trends that may indicate increases or decreases in operating efficiencies. This measure is also compared against budget to alert management to trends that may cause actual results to deviate from planned operational results. We provide this measure to our investors to allow them to also monitor operational efficiencies of our mines. We calculate this measure for both individual operating units and on a consolidated basis. Cash operating cost per ounce should be considered as Non-GAAP Financial Measures as defined in SEC Regulation S-K Item 10 and other applicable securities laws 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 this measure does not incorporate revenues, changes in working capital and non-operating cash costs, it is 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.
