TORONTO, April 13, 2016 /PRNewswire/ -� Golden Star Resources Ltd. (NYSE MKT: GSS; TSX: GSC; GSE: GSR) ("Golden Star" or the "Company") is pleased to announce that first quarter production exceeded expectations with approximately 53,000 ounces of gold produced.�  Preliminary cash operating costs for the first quarter are estimated at below $750 per ounce, also lower than expected.�  In addition, the Company received $20 million from RGLD Gold AG ("RGLD"), a subsidiary of Royal Gold, Inc., on April 1, 2016, as per the payment schedule established in the amended streaming agreement announced on December 31, 2015.

"As we began demonstrating our ability to deliver reliable production and stability in costs in the fourth quarter last year, these first quarter 2016 results continue to enhance confidence in our ability to deliver on the low-cost producer strategy that was introduced in 2013," commented Sam Coetzer, President and CEO of the Company.�  "The payment from Royal Gold was also an important milestone for the Company as it indicates Royal Gold's ongoing confidence in the final design of our Prestea Underground project which the funds are earmarked for.�  With all of the necessary funding committed in order to develop and place into production our two new underground projects over the next year and a half, the Company can continue to focus on its balance sheet and the generation of cash flow that can be used to further reduce debt."

First Quarter Production and Costs

Production in the first quarter of 2016 was from the open pit operations with approximately 22,000 ounces of production from Prestea and approximately 31,000 ounces from Wassa.�  The open pit operations at both Wassa and Prestea are expected to be the primary source of production through 2016 as development work continues on the respective underground projects.�  The new underground projects are scheduled to begin contributing to production beginning late this year from the Wassa Underground and in mid-2017 for the Prestea Underground, thereby increasing annualized production levels by approximately 25% beginning in late 2017.

The preliminary cash operating costs estimated for the first quarter of 2016 are below $750 per ounce reflecting a level that is consistent with the new lower cost structure that has been established by the Company.�  This significant change in the cost structure was achieved through the suspension of the high-cost, high power-consuming refractory production that was suspended last year, other operational improvements and cost management measures that have been implemented.�  As the Company's entire mineral reserve base and sources of planned production are comprised solely of non-refractory ounces, the Company is confident that its lower cost structure is sustainable going forward as further improvements are being evaluated.

Streaming Agreement Funds Received

The $20 million payment from RGLD was paid on April 1, 2016, after the Company met certain conditions which include the acceptance by RGLD of the final design of the Prestea Underground mine.�  This payment brings the total payments made to date to $95 million of the total $145 million expected before the end of 2016 and is an important milestone for the Company.�  The development of the Prestea Underground project continues and is on track to commence production in mid-2017.

Non-GAAP Financial Measures
In this news release, we use the terms "cash operating cost per ounce.�  This should be considered as a non-GAAP financial measure as defined in applicable Canadian and United States securities laws and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. "Cash operating cost per ounce" for a period is equal to the Company's cost of sales excluding depreciation and amortization for the period less royalties and production taxes, minus the cash component of metals inventory net realizable value adjustments and severance charges divided by the number of ounces of gold sold during the period.�  Golden Star uses cash operating cost per ounce as a key operating indicator. Golden Star monitors this measure monthly, comparing each month's values to prior quarters' values to detect trends that may indicate increases or decreases in operating efficiencies. The Company provides this measure to investors to allow them to also monitor operational efficiencies of the Company's mines. Since cash operating costs 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 International Financial Reporting Standards ("IFRS"). For additional information regarding the Non-GAAP financial measures used by the Company, please refer to the heading "Non-GAAP Financial Measures" in the Company's Management Discussion and Analysis of Financial Condition and Results of Operations for the Year Ended December 31, 2015, available at www.sedar.com.
