Sam Coetzer, President and CEO of Golden Star, commented:

"Recent market dynamics combined with ongoing in-country operating challenges have reaffirmed our commitment to our stated strategy.  That strategy remains to favour margin over ounces and to pursue growth from low cost non-refractory ore sources.  In this context we have made two critical changes to our near term operating plan.  We have commenced open pit mining at Prestea's surface deposits to deliver higher margin ounces to the non-refractory plant at Bogoso.  These will replace lower margin production from tailings retreatment.  The suspension of the Bogoso refractory business in a responsible manner will commence with immediate effect.  The result of these changes is a reduction in total ounces produced but an increase in potential returns to shareholders as direct operating costs are expected to reduce dramatically.

Our development projects have progressed well over the quarter.  With the closure of the financing transaction with Royal Gold we can accelerate these projects to deliver ounces in 2016.  At Wassa construction of the twin declines has started and the project is on schedule.  Ongoing operations at Wassa have not been impacted by the project and production at this mine was improved in the quarter.  At Prestea underground we will shortly release the findings of the Feasibility Study which I expect to show improvements in capital efficiency.  We remain on target to transform this business to a lower cost gold producer by the end of 2016."

Company Profile:

Golden Star Resources (NYSE MKT: GSS; TSX: GSC; GSE: GSR) ("Golden Star" or the "Company") is an established gold mining company that holds a 90% interest in the Wassa, Prestea and Bogoso gold mines in Ghana.  In 2014, Golden Star produced 261,000 ounces of gold.  The Company is financed to pursue brownfield development projects at its Wassa and Prestea mines which are expected to transform these mines into lower cost producers from 2016 onwards.  As such, Golden Star offers investors leveraged exposure to the gold price in a stable African mining jurisdiction with significant development upside potential.

Summary of Consolidated Operational and Financial Results:

¹ See "Non-GAAP Financial Measures".

Review of Financial Performance

Gold produced and sold in the period was 55,132 ounces compared to 63,245 ounces in the prior quarter with weaker production from the Bogoso refractory business.  This reduced production was the key driver of lower revenue for the second quarter of $65.8 million. 

Cost of sales before depreciation and amortization increased from $72.2 million in the prior quarter to $78.7 million in the second quarter.  This was primarily as a result of severance charges of $13.0 million accrued at Bogoso in preparation for the suspension of the refractory operations.  Mine operating expenses were $60.2 million for the second quarter reduced from $69.2 million in the prior quarter primarily as a result of fewer tonnes mined and milled at Bogoso.  Mine operating losses were $26.1 million compared to $7.3 million in the prior quarter.

Corporate general and administrative expenditures were $4.8 million compared to $3.6 million in the prior quarter as non-cash expenses of $1.0 million relating to share-based compensation were accrued in the quarter.

In line with the decision to suspend the refractory business at Bogoso and in recognition of the recent decline in the gold price, impairment charges of $34.4 million was taken at the end of the quarter.  The charge was comprised of $8.7 million on mining interests, $12.9 million on materials and supplies inventory and $12.8 million on refractory ore inventory.  After this impairment and severance costs at Bogoso of $13.0 million, the adjusted net loss attributable to Golden Star shareholders for the second quarter was $16.0 million. 

Cash used in operations before changes in working capital for the second quarter was $8.7 million and capital expenditures for the second quarter totaled $12.8 million.  Further capital expenditure of $50 million is expected for the year on the Wassa and Prestea mines. 

The consolidated cash balance was $21.4 million at June 30, 2015 after the drawdown of $15.0 million on the Ecobank loan II in late June 2015.  Subsequent to period end, a $20.0 million loan from Royal Gold was received and the $40 million in an initial upfront payment on the stream from Royal Gold's subsidiary is expected tomorrow July 30, 2015.  These funds will be applied to the retirement of $38.0 million in debt outstanding on the Ecobank I loan.

Review of Operational Performance

Wassa Operations

¹   See "Non-GAAP Financial Measures".

Ore tonnes mined in the second quarter increased 35% from the prior quarter as mining transitioned back into the Main pit from the Starter pit where operations were focused in the first quarter.  Grade mined and processed increased as expected with this shift to a higher grade zone.  Stripping increased in line with the forecast stripping ratio of approximately 4:1 for 2015.

Ore processed in the quarter declined marginally from the prior quarter with a crusher failure in June that resulted in a number of days of plant downtime.  However as a result of the higher grade, gold produced and sold at Wassa in the quarter increased to 24,829 ounces from 23,194 ounces in the prior quarter. 

Mine operating expenses declined marginally with increased mining efficiencies in the larger Main pit and fewer tonnes processed.  However cash operating costs per ounce reduced considerably to $918 as a result of the combination of lower expenses and improved grade. 

During the quarter, $2.8 million of capital was invested in the expansion of the tailings storage facility and improvements to the processing plant at Wassa.

Wassa open pit operations are performing satisfactorily with 48,023 ounces produced in 2015.  Expectations remain that the mine will perform in line with original guidance.  In July Wassa achieved 10 million lost time injury free hours and has had no medically treated injury recorded for over a year.

With solid production year to date and good progress on its development projects, Wassa is expected to continue to perform for the remainder of 2015.  Operational and costs expectations have been refined for the full year with production of 110,000 – 115, 000 ounces at a cash operating cost of $860 – 990 per ounce expected.

Bogoso Operations

Refractory mining in the second quarter was exclusively from the Chujah pit which is approaching the end of its mine life.  Accordingly tonnes mined declined in line with the mine plan and stockpiles were reduced with more tonnes processed than mined.  Approximately three quarters of Bogoso's mining fleet at the start of the year has now been redeployed to Wassa.  The remaining ore at Chujah is being mined by contractors.

Tonnes processed declined from the prior quarter.  Continued voltage fluctuations in the power supply over the quarter not only impacted the plant's ability to run at full capacity but also caused extensive damage to the milling circuit.  Repairs to this circuit further reduced the plant's availability over the quarter.  Grade mined and processed in the quarter was also below expectations.

Bogoso gold production and sales totaled 30,303 ounces in the second quarter compared to 40,051 ounces in the prior quarter and which combined with the lower realized gold price resulted in a decline in revenue to $36.2 million.  

¹ See "Non-GAAP Financial Measures".

Tailings retreatment continued in the quarter at a slower pace as the anticipated seasonal impact of rainfall limited hydraulic mining.  For the remainder of 2015, tailings retreatment activities will be reduced to provide processing capacity in the non-refractory plant for Prestea South ore.

In the second quarter Bogoso's mine operating expenses were $35.8 million, a notable reduction from the prior quarter.  In addition to these expenses, $13 million was accrued in anticipation of severance payments to Bogoso staff in anticipation of the suspension of the refractory business. 

Primarily as a result of lower tonnes processed at lower grades, cash operating cost per ounce totaled $1,273 for the second quarter, compared to $1,027 per ounce in the prior quarter.

Although significant cost and complexity was anticipated in the suspension of Bogoso's refractory business, expectations were that production in the second quarter would be far higher.  Significant management time and maintenance capital will be required to ensure that the remaining ore is mined and processed profitably.  This situation combined with the recent decline in gold price has led management to conclude that an immediate suspension of the refractory operation is best to preserve shareholder value.  With production now expected from Prestea open pits in the third quarter, the guidance for the remainder of the year has been revised down from 75,000 – 85,000 ounces to 20,000 – 25,000 ounces bringing full year production from Bogoso to between 95,000 and 100,000 ounces at a cash cost of between $1,065 - 1,150 per ounce.

Capital expenditures at Bogoso were negligible in the second quarter.   

Review of Development Projects

Wassa Underground

Drilling below the Wassa Main pit since late 2011 was successful in increasing the Wassa Mineral Resource.  In March 2015 the results of a Feasibility Study on the economic viability of an underground mine were announced and the decision to progress with the construction of the underground mine was affirmed.  The underground mine will operate in conjunction with the existing open pit mine and the primary access will be a twin decline from the Wassa Main pit.

Infrastructure preparations for the exploration decline progressed well during the second quarter of 2015.  The following is a summary of the major recent advances:

• Mining equipment has arrived on site;
• The installation of the electrical infrastructure, including 4MVA generator capacity, is progressing well;
• The first blast for the development of the decline took place in July 2015 and development of the decline is ongoing; and
• The construction of support infrastructure is on target.

It is anticipated that the stoping will commence late in the first quarter of 2016 with first gold from underground expected in the second quarter 2016.

Capital expenditures of $3.4 million on the underground development in the quarter included support and electrical infrastructure construction and installation and the procurement of mobile mining equipment.  Aprroximately$10 million in capital expenditure is expected at Wassa underground for the remainder of the year.

Prestea Mine

Prestea mine consists of an underground mine that has been in existence for over 100 years along with adjacent surface deposits.  The mine is located 16 km south of the Bogoso mine and processing plants in the town of Prestea.  The underground mine is currently on care and maintenance.  A number of high grade surface deposits exist to the south of the underground mine that have historically been exploited by artisanal miners.  There are associated support facilities for both these operations.

The surface deposits are host to 122,000 ounces of non-refractory Mineral Reserves at an average grade of 2.24 g/t Au.  The environmental permit required to commence mining was issued by the Environmental Protection Agency in June 2015 after extensive impact assessment studies and local community consultations were undertaken.  Mining of these surface operations began early in the third quarter and this material will be processed at the Bogoso non-refractory plant where tailings retreatment has been ongoing of late.  Prestea South production is included in the guidance for Bogoso for the remainder of 2015 and is expected to contribute meaningfully in the last quarter of the year.

The preliminary economic assessment ("PEA") on the development of the Prestea underground mine was completed and published on SEDAR in 2014.  The PEA, which is based on development of a non-mechanized mining operation, indicated a post-tax IRR of 72% and net present value of $121 million at a $1,200 per ounce gold price.  Cash operating costs of $370 per ounce and all-in sustaining costs of $518 per ounce were estimated over the life of mine.

The Feasibility Study to confirm this assessment is ongoing and work is progressing well with opportunities for improved capital efficiency recently identified.  Results of the study are expected to be published this quarter.  The Company plans to bring Prestea underground mine into production by 2016 pending the completion of the study and receipt of environmental permits.

During the second quarter of 2015, the Company incurred capital expenditures totaling $5.5 million at Prestea.  The Company plans to spend a further $20 million on capital at Prestea in 2015.

Outlook

Bogoso refractory operations will be discontinued during the third quarter to preserve shareholder value.  All focus will be on bringing Prestea South into production and continuing the infrastructure upgrade at Prestea Underground to ensure production in 2016 is achieved.  As a result full year consolidated production is now expected to be 205,000 – 215,000 ounces at a cash cost per ounce of $955 – 1,050.

The Board and management are confident that this transition is critical to ensuring the optimal allocation of funds recently raised and achieving the Company's strategy of transforming to a low cost non-refractory producer by 2016.

Non-GAAP Financial Measures

In this press release, we use the terms "cash operating cost per ounce", "adjusted net loss attributable to Golden Star shareholders" and "all-in sustaining cost per ounce".  These should be considered as non-GAAP financial measures 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.

"Cost of sales excluding depreciation and amortization" as found in the statements of operations includes all mine-site operating costs, including the costs of mining, ore processing, maintenance, work-in-process inventory changes, mine-site overhead as well as production taxes, royalties, and by-product credits, but excludes exploration costs, property holding costs, corporate office general and administrative expenses, foreign currency gains and losses, gains and losses on asset sales, interest expense, gains and losses on derivatives, gains and losses on investments and income tax expense/benefit.

"All-in sustaining costs" commences with cash operating costs and then adds sustaining capital expenditures, corporate general and administrative costs, mine site exploratory drilling and greenfield evaluation costs and environmental rehabilitation costs.  This measure seeks to represent the total costs of producing gold from current operations, and therefore it does not include capital expenditures attributable to projects or mine expansions, exploration and evaluation costs attributable to growth projects, income tax payments, interest costs or dividend payments.  Consequently, this measure is not representative of all of the Company's cash expenditures.  In addition, the calculation of all-in sustaining costs does not include depreciation expense as it does not reflect the impact of expenditures incurred in prior periods.  Therefore, it is not indicative of the Company's overall profitability.

"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 and severance charges 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 quarters' values to detect trends that may indicate increases or decreases in operating efficiencies.  We provide this measure to investors to allow them to also monitor operational efficiencies of the Company's mines.  We calculate this measure for both individual operating units and on a consolidated basis.  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"). 

In order to indicate to stakeholders the Company's earnings excluding the non-cash (gain)/loss on the fair value of the Company's outstanding convertible debentures and non-cash impairment charges, the Company calculates "adjusted net loss attributable to Golden Star shareholders" to supplement the condensed interim consolidated financial statements.

Changes in numerous factors including, but not limited to, our share price, risk free interest rates, gold prices, mining rates, milling rates, ore grade, gold recovery, costs of labor, consumables and mine site general and administrative activities can cause these measures to increase or decrease.  The Company believes that these measures are similar to the measures of other gold mining companies, but may not be comparable to similarly titled measures in every instance.

In the current market environment for gold mining equities, many investors and analysts are more focused on the ability of gold mining companies to generate free cash flow from current operations, and consequently the Company believes these measures are useful non-IFRS operating metrics ("non-GAAP measures") and supplement the IFRS disclosures made by the Company.  These measures are not representative of all of Golden Star's cash expenditures as they do not include income tax payments or interest costs.  There is material limitations associated with the use of such non-GAAP 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.

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 three and nine months ended September 30, 2014 and the Company's Management Discussion and Analysis of Financial Condition and Results of Operations for the Year Ended December 31, 2013, available at www.sedar.com.

Cautionary note to U.S. investors

This news release has been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ materially from the requirements of United States securities laws applicable to U.S. companies.  The terms "mineral reserve", "proven mineral reserve" and "probable mineral reserve" are Canadian mining terms as defined in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101").  These definitions differ from the definitions of the Securities and Exchange Commission (the "SEC") set forth in Industry Guide 7 under the United States Securities Exchange Act of 1934, as amended (the "Exchange Act").  Under SEC Industry Guide 7 standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made.  Among other things, all necessary permits would be required to be in hand or issuance imminent in order to classify mineralized material as reserves under the SEC standards.  Under SEC Industry Guide 7 standards, a "final" or "bankable" feasibility study is required to report reserves, the three-year historical average price is used in any reserve or cash flow analysis to designate reserves and the primary environmental analysis or report must be filed with the appropriate governmental authority.

In addition, the terms "mineral resource", "measured mineral resource", "indicated mineral resource" and "inferred mineral resource" are defined in and required to be disclosed by NI 43-101; however, these terms are not defined terms under SEC Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with the SEC. Investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into reserves.  "Inferred mineral resources" have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility.  It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category.  Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases.  Investors are cautioned not to assume that all or any part of an inferred mineral resource exists or is economically or legally mineable.  Disclosure of "contained ounces" in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute "reserves" by SEC Industry Guide 7 standards as in place tonnage and grade without reference to unit measures.

For the above reasons, information contained in this news release and the documents referenced herein containing descriptions of our mineral deposits may not be comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements under the United States federal securities laws and the rules and regulations thereunder.
