Golden Star Reports Third Quarter 2015 Results

TORONTO, Oct. 28, 2015 /CNW/ - Golden Star today reports its financial and operational results for the quarter ended September 30, 2015 ("the third quarter" or "the period").  All references to currency are in US dollars.

Golden Star continued to execute its plan to transition to a higher margin, lower cost producer.  During the quarter, four key elements of this plan were advanced including unit cost reductions through increased productivity, continued development of the high grade underground deposits at Wassa and Prestea, commencement of mining of free milling ore at Prestea surface operations, and suspension of the refractory plant.

Consolidated Operational Results:

• Gold produced and sold during the third quarter was 51,898 ounces compared to 55,132 ounces in the prior quarter
• Revenue for the third quarter was $56.5 million compared to $65.8 million for the prior quarter
• Cost of sales before depreciation and amortization reduced to $55.2 million from $78.7 million in the prior quarter
• Consolidated cash operating cost per ounce¹ was $988 for the third quarter compared to $1,113 in the prior quarter
• Net loss for the third quarter was $6.8 million, or $0.03 per share, compared to a net loss of $61.5 million, or $0.24 per share, in the prior quarter

Unit Operational Results:

• Wassa Open Pit produced 28,848 ounces compared with 24,829 ounces in the prior quarter
• Wassa cash operating costs¹ decreased to $770 per ounce from $918 per ounce in the prior quarter
• Refractory operations were suspended at Bogoso during the third quarter, resulting in production of 15,648 ounces compared with 25,702 ounces in the prior quarter
• Bogoso/Prestea produced 23,050 ounces at $1,261 per ounce cash operating cost compared with 30,303 ounces at $1,273 per ounce in the prior quarter

Project Development:

• Wassa Underground decline was advanced by 205 meters at the end of the third quarter, and it has reached 382 meters to date
• Prestea Open Pits mining commenced in August 2015 and the non-refractory business line at Bogoso/Prestea produced 7,402 ounces in the third quarter compared to 4,601 ounces in the prior quarter
• Prestea Underground Mine rehabilitation commenced in September and production is anticipated to resume in 2017
• The loan and stream financing from Royal Gold, Inc. and its wholly-owned subsidiary respectively was completed with $20 million received under the term loan and $55 million of the $130 million stream advance received

Cash provided by operations for the third quarter was $45.3 million which includes the incremental stream proceeds received from Royal Gold.  Consolidated cash balance was $27.7 million at quarter end.

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

"I am confident that Golden Star has reached the stage where we are managing a less complex and more streamlined business. This was achieved with the suspension of the refractory plant, the reduction in workforce, the startup of mining from the Prestea Open Pits, and the progress made at Wassa Underground development. Having arranged financing with Royal Gold for $150 million, we are now in a position to bring our two new low cost projects into production. These achievements are a reflection of the focus and dedication of the Golden Star team, the quality of our assets, and the clarity of our vision."

Golden Star management will conduct a conference call and webcast on October 29, 2015, at 10:00am EDT to discuss these results.

Review of Financial Performance

Gold produced and sold in the period was 51,898 ounces compared to 55,132 ounces in the prior quarter. Gold produced and sold at Wassa increased, due to higher throughput and higher grade, which partially offset the reduction in ounces produced and sold at Bogoso/Prestea due to the suspension of refractory operation in the quarter. The continued decline in gold price and fewer ounces sold reduced revenue for the third quarter to $56.5 million. 

Consolidated cash operating costs per ounce for the quarter decreased to $988 from $1,113 in the prior quarter. This reduction was largely achieved through an 11% reduction in cash operating costs per ounce at Wassa as a result of cost cutting measures implemented by the Company. All-in sustaining costs per ounce decreased from $1,302 in the prior quarter to $1,151 for the third quarter.   

Cost of sales before depreciation and amortization decreased from $78.7 million in the prior quarter to $55.2 million in the third quarter. This was mainly a result of lower mining operating expenses at Wassa and Bogoso/Prestea and a $12.3 million reduction in severance expense. Mine operating expenses of $54.4 million for the third quarter reduced from $60.2 million in the prior quarter due to the suspension of the high costs refractory operation and the start of the lower cost non-refractory operation at Bogoso/Prestea. The mine operating loss was reduced to $4.3 million from $26.1 million in the prior quarter. 

The adjusted net loss attributable to Golden Star shareholders for the third quarter was $10.8 million, and the adjusted loss per share was $0.04.

Cash provided by operations before changes in working capital for the third quarter was $38.5 million and capital expenditures for the third quarter totaled $17.8 million. Further capital expenditure of $21 million is expected for the remainder of the year on the Wassa and Prestea mines. 

The consolidated cash balance was $27.7 million at September 30, 2015. During the quarter the Company received $75 million from Royal Gold, consisting of a $20 million term loan payment and $55 million in advanced payments in relation to the stream financing. Approximately $39 million of these funds were used to retire the Ecobank I loan early in the third quarter.

¹   See "Non-GAAP Financial Measures".

Ore tonnes mined in the third quarter remained in line with the prior quarter.  Throughput and grade continued to increase from the prior quarter resulting in increased gold produced and sold at Wassa, and an increase in revenue.  Stripping remained in line with the forecast stripping ratio of approximately 4:1 for 2015.

Cash operating costs per ounce continued to decline, down 16% from the prior quarter to $770 per ounce as a result of cost cutting measures implemented by the Company.  Mine operating expenses in the third quarter were 4% lower than the prior quarter. 

Capital expenditures for the quarter were $8.5 million, of which $5.8 million was incurred on the development of the Wassa Underground Mine. 

Bogoso/Prestea Operations

The Prestea Mines consist of an underground mine that has been in existence for over 100 years along with adjacent surface deposits. The surface deposits are host to approximately 122,000 ounces of non-refractory Mineral Reserves at an average grade of 2.24 g/t Au. The environmental permit required to mine the surface deposits was issued by the Environmental Protection Agency in June 2015 after Golden Star undertook extensive environmental and community impact assessments and local community consultations. Mining of these surface operations began early in the third quarter and 20,000 - 25,000 ounces of gold are expected to be produced in 2015 from the Prestea Open Pits.

The Bogoso refractory operation was suspended during the third quarter 2015. The processing of non-refractory tailings was suspended in order to make way for the processing of higher grade ore from the Prestea Open Pits at the Bogoso non-refractory plant.

¹   See "Non-GAAP Financial Measures".

Total ore mined for the quarter was 239,719 tonnes, of which 179,186 tonnes were non-refractory ore from Prestea Open Pits. Refractory ore mined was reduced dramatically due to the suspension of refractory operations in the third quarter.    

The grade and recovery of the non-refractory ore increased with the processing of higher grade ore from Prestea Open Pits. The refractory ore grade and recoveries declined as the refractory processing plant was suspended. 

Bogoso/Prestea gold production and sales totaled 23,050 ounces in the third quarter compared to 30,303 ounces in the prior quarter and combined with the lower realized gold price resulted in a decline in revenue to $24.8 million.  

Third quarter mine operating expenses continued to reduce to $31.0 million.  Cash operating costs per ounce reduced slightly to $1,261, down from $1,273 in the prior quarter.

Capital expenditures increased to $9.3 million for the quarter.  Included in this is $6.7 million which was spent on Prestea Underground development and $2.1 million on the development of Prestea Open Pits.   

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 operating in conjunction with the existing open pit mine were announced and the decision to progress with the construction of the underground mine was affirmed.

Decline development commenced in July 2015 and 382 meters of advance was achieved on the Main and Ventilation declines to date. Currently the declines are achieving an average advance of seven meters per day. This advance is expected to increase over the next month as efficiencies and cycle times improve.

An update to the resource model has been completed which includes additional drilling undertaken between July 2014, when the Feasibility Study resource model was completed, and March 2015. Currently the new resource model is being used to update the mine design and the production schedule. The Wassa underground orebody consists of the B Shoot (the main component of the current resource) and the F Shoot, a parallel zone of mineralization. Through recent drilling success, the F Shoot area has increased in the new resource estimate and we expect to access the area in March 2016 from the decline currently being developed.

Construction of the surface infrastructure is complete and transfer from generator power to grid power is expected in the fourth quarter 2015.

The project to date has incurred capital expenditures totaling $15.2 million. The Company expects to incur approximately $6 million on capital for the remainder of 2015.

Prestea Underground

The Prestea Mines are located 16 km south of the Bogoso processing plants in the town of Prestea. Prestea Open Pits are now in operation, while the underground mine is currently in re-development.

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 internal rate of return (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.

Construction capital expenditure for the underground mine was approved during the third quarter of 2015 and work has commenced on procurement for long-lead electrical and winder upgrade components.

The resource model was updated during July 2015 to include additional geotechnical and metallurgical holes drilled. The Feasibility Study is expected to be finalized in the fourth quarter of 2015 to include these additional resources.

Rehabilitation works are ongoing in 17 level and 24 level access development and in the Central Shaft. All rehabilitation works are on schedule for completion in the first quarter of 2016. Mechanical and electrical rehabilitation work is planned to be completed in the third quarter of 2016 whereupon development is expected commence. Pre-development of the resource is expected take place from the fourth quarter of 2016 to mid-2017. Stoping is expected to start in mid-2017, ramping up to 500 tonnes per day by the end of 2017.

During the nine months ended September 30, 2015, the Company incurred capital expenditures totaling $13.7 million on Prestea Underground operations and $2.7 million on the development of Prestea Open Pits. The Company expects to incur approximately $12 million of capital expenditures for the remainder of 2015 at Bogoso/Prestea.

Outlook

The Company continues to advance its strategy of transforming to a low cost non-refractory producer.  Prestea Open Pits are now in production, providing lower cost, non-refractory ounces, with grade expected to improve further in future. The refractory operation is now fully suspended, and the Company's focus is on first production at Prestea Underground. Wassa continues to achieve low cost production, and Wassa Underground development is progressing well. Cash operating costs are expected to continue to reduce at both operations. With this continued success, the Company expects to meet full year production guidance of 205,000 to 215,000 ounces at cash operating costs between $955 and $1,050 per ounce.

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.

"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"). 

"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.

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.

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 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.
