Second Quarter Production and Costs

Golden Star produced 42,461 ounces of gold during the second quarter of 2016 from its open pit operations, with production from Wassa of 21,543 ounces of gold and production from the Prestea Gold Mine ("Prestea")� of 20,918 ounces of gold.� 

Golden Star expected there to be a decline in second quarter 2016 production compared to the first quarter due to a scheduled maintenance shutdown at the Wassa processing plant, in addition to the seasonality traditionally impacting the second and third quarters of the year.�  The planned shutdown lasted for 2.5 weeks and during this time Golden Star's operational team rebuilt the ball mill foundation, replaced critical components of the primary crusher and upgraded the electrical system in the carbon-in-leach plant.�  This work was completed successfully and the operational team has reported an increase in throughput as a result.

At the half year, Golden Star remains on track to achieve its 2016 production guidance of 180,000-205,000 ounces of gold with cash operating costs of $815-$925 per ounce (see "Non-GAAP Financial Measures" below).�  The Company also continues to expect sustaining capital expenditure of $9 million and development capital expenditure of $81 million for total capital spending of $90 million for the year.

Post-Period Events

Pre-commercial production commenced at Wassa Underground on July 10, 2016.�  The successful blasting of the first stope in the F Shoot delivered the first ore from the new underground mine to the Wassa processing plant.�  This first stope was in the upper part of the F Shoot, which is one of the more moderate grade areas of the deposit.�  The higher grade areas within the B Shoot are scheduled to be accessed in early 2017.�  Ore from Wassa Underground will be mined in conjunction with ore from the Wassa Main pit and blended for feeding to the processing plant.

Golden Star received $20 million from RGLD on July 1, 2016, pursuant to the payment schedule established in the amended streaming agreement announced on December 31, 2015.�  This payment brings the payments made to date to $115 million of the total $145 million expected before the end of January 2017.�  Payments under the amended streaming agreement are being used to enable Golden Star to continue its transformation to becoming a low cost, non-refractory gold producer.

Sam Coetzer, President and Chief Executive Officer of Golden Star, commented:

"At the half year point, we are well-positioned to achieve our guidance for full year production, cash operating costs and capital expenditure.�  Although the second quarter was weaker than the first quarter, as expected, I am pleased that the upgrades to the Wassa processing plant were completed on time and on budget.�  The plant is now in good shape to process the higher grade ore coming from Wassa Underground, following the blasting of the first stope on July 10, 2016.�  Golden Star is at an exciting point in its transformation and I look forward to updating the market on other important milestones, such as the start of the development of Prestea Underground Mine, during the second half of the year."

Golden Star will announce its full Second Quarter 2016 operational and financial results after market close on July 27, 2016, as previously announced.

Non-GAAP Financial Measures

In this press release, we use the term "cash operating cost per ounce".�  This term should be considered to be 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 "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 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. Golden Star 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").� 

These non-GAAP financial measures are not representative of all of Golden Star's cash expenditures as they do not include income tax payments or interest costs.�  There are material limitations associated with the use of such non-GAAP financial measures.�  Since these measures do not incorporate all non-cash expense and income items, 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 IFRS.
