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

"During the second quarter of 2018, Prestea Underground delivered more ounces than the Prestea Open Pits, which is testament to the hard work and disciplined approach of our underground team.  We expect to see further improvements during the coming months and we anticipate that Prestea Underground will achieve its nameplate production rate during the fourth quarter of 2018.  We will also continue to right size this operation with the aim of reducing operating costs and generating a stronger cash margin.  Wassa Underground delivered another impressive quarter, with both grades and tonnages exceeding our expectations.  I am looking forward to releasing the Preliminary Economic Assessment for Wassa's Inferred Mineral Resources to gain a more thorough understanding of the full potential of this substantial deposit.  After two quarters, we are on track to achieve our consolidated full year 2018 production and cost guidance and with our strategic relationship with La Mancha agreed, we are well-positioned to deliver significant value for our shareholders."

SUMMARY OF CONSOLIDATED OPERATIONAL AND FINANCIAL RESULTS

 

 

 

 

OPERATIONAL PERFORMANCE

Overview

In the second quarter of 2018 Golden Star produced 61,209 ounces of gold. This quarter was the Company's second quarter as a primarily underground-focused gold producer, following the cessation of production from the Wassa Main Pit in January 2018.  Production from the Prestea Open Pits is ongoing and ore supply from this operation is expected to continue into the middle of the third quarter of 2018.  However once production from the Prestea Open Pits concludes, Golden Star intends to focus on high margin, underground ore with the objective of strengthening its financial position and creating a robust platform to deliver shareholder value.

The Wassa Complex delivered another strong quarter. Gold production increased by 20% in the second quarter of 2018 to 38,532 ounces compared to the second quarter of 2017 and it increased by 9% compared to the first quarter of 2018. 92% of Wassa's production was attributable to Wassa Underground, which delivered higher grades and higher tonnages than expected.  Consequently, Wassa delivered its lowest cash operating cost per ounce¹ in over seven years of $610.

Gold production from the Prestea Complex ("Prestea") was 22,677 ounces in the second quarter of 2018. The second quarter of 2018 was the first quarter that Prestea Underground delivered more ounces than the Prestea Open Pits (55% of the Prestea Complex's total production), which is a result of the ramp up of production from the underground operation and the Prestea Open Pits approaching the end of their mine life.  The grade of the ore processed from Prestea Underground increased by 65% in the second quarter of 2018 compared to the first quarter of 2018 and Golden Star expects the targeted production rate of 650 tpd to be achieved at Prestea Underground during the fourth quarter of 2018.

Golden Star's consolidated cash operating cost per ounce¹ was $809 in the second quarter of 2018, which represents a 3% increase compared to the second quarter of 2017. Although Wassa reported a 38% decrease in cash operating cost per ounce¹ to $610, this was offset by a 96% increase at Prestea to $1,149.

The AISC per ounce¹ in the second quarter of 2018 was $1,104, an increase of 15% compared to the second quarter of 2017, primarily as a result of the slower than expected ramp up at Prestea Underground.  The cost of sales per ounce¹ was $1,106.  Golden Star expects its operating costs to decrease in the second half of 2018 as production at both underground operations continues to ramp up.

At the end of the first half of 2018, $14.2 million of severance expenses had been paid in total. The severance payments relating to the Wassa Main Pit workforce are now complete and Golden Star expects to pay the severance expenses relating to the Prestea Open Pits workforce during the remainder of 2018. 

At the end of the second quarter of 2018, Golden Star is on track to achieve its consolidated FY 2018 guidance in terms of gold production, cash operating cost per ounce¹ and AISC per ounce¹ and expects to be at the top end of the cost guidance ranges.  As stated in the press release dated January 11, 2018, Golden Star expects production to be weighted to the second half of 2018 and consequently, cash operating cost per ounce¹ and AISC per ounce¹ are anticipated to be lower in the second half of 2018.

Following the completion of the proposed strategic investment by La Mancha, Golden Star intends to review its planned capital spend.  It is expected that some of the proceeds of the transaction will be used for exploration, Mineral Resource delineation and expansion programs at Wassa Underground, Prestea Underground and the Father Brown deposit.

 

Wassa Complex

 

 

Wassa Operational Overview

Gold production from the Wassa Complex increased by 20% in the second quarter of 2018 to 38,532 ounces compared to the second quarter of 2017. Wassa became a primarily underground operation in the first quarter of 2018 and consequently, in the second quarter of 2018, 92% of Wassa's production was attributable to Wassa Underground. Stockpiled ore from Wassa Main Pit is expected to continue to be fed to the processing plant into the fourth quarter of 2018.

The grade of the ore from Wassa Underground in the second quarter of 2018 increased by 65% to 4.99 g/t Au compared to the second quarter of 2017 and by 10% compared to the first quarter of 2018.  Mining rates at Wassa Underground also continued to exceed expectations, at approximately 2,655 tpd on average in the second quarter of 2018. This represents a 66% increase compared to the second quarter of 2017 and an 11% increase compared to the first quarter of 2018. 

The targeted average mining rate for Wassa Underground in FY 2018 is 2,700-3,000 tpd, but the Company expected to achieve an average of 2,300 tpd during the first half of 2018.  The mining team is well-positioned to continue to increase the tonnage profile in 2018 and beyond, with the mining sequence working well and an increasing number of stopes prepared and developed. 

The Wassa Complex reported a 38% decrease in cash operating cost per ounce¹ for the second quarter of 2018 to $610 compared to the second quarter of 2017. This represents Wassa's lowest cash operating cost per ounce¹ since the first quarter of 2010. This strong performance was due primarily to the increase in both grade and tonnage from the Wassa Underground ore being fed to the processing plant and the subsequent increase in gold sold. The cost of sales per ounce¹ for Wassa in the second quarter of 2018 was $944. 

$1.6 million of severance expenses were paid during the second quarter of 2018 as a result of the cessation of production from Wassa Main Pit in the first quarter of 2018.  The severance payments relating to the Wassa Main Pit workforce are now complete.

Post period end, Wassa's First Aid Team was awarded first place in the 2018 Zone 1 Mine Safety and First Aid Competition, underlining Golden Star's strong commitment to safe working practice.  The team will go on to compete in the national competition in October 2018.

 

Prestea Complex

 

 

Prestea Operational Overview

Gold production from the Prestea Complex in the second quarter of 2018 was 22,677 ounces.  The second quarter of 2018 was the first quarter that Prestea Underground delivered more ounces than the Prestea Open Pits (55% of the Prestea Complex's total production).  This is a result of the ramp up of production from the underground operation and the Prestea Open Pits approaching the end of their mine life.

The Prestea Open Pits produced 10,214 ounces of gold in the second quarter of 2018. This 68% decrease in production compared to the second quarter of 2017 was anticipated, as the Prestea Open Pits had been expected to complete gold production at the end of 2017. However additional ore was sourced during the first half of 2018 so production is now expected to complete during the third quarter of 2018.  The grade of the ore processed from the Prestea Open Pits in the second quarter of 2018 was 2.33 g/t Au. This was higher than expected at the start of the year as Golden Star has accessed the Maafio pit, which has a grade of approximately 2.33 g/t Au. However the grade processed in the second quarter of 2018 represents a 26% decrease compared to the second quarter of 2017, as during the second and third quarters of 2017 Golden Star was mining the Mampon deposit, which had a grade of 4.64 g/t Au.

Gold production from Prestea Underground was 12,463 ounces in the second quarter of 2018, compared to 325 ounces in the second quarter of 2017. The grade of the ore processed from Prestea Underground increased by 65% in the second quarter of 2018 to 13.56 g/t Au compared to the first quarter of 2018, exceeding the average ore reserve grade of 12.35 g/t Au. 

The average production rate from Prestea Underground was 345 tpd in the second quarter of 2018. This average daily tonnage rate was similar to the first quarter of 2018, however, more ore was sourced from stope production during the second quarter of 2018 and the dilution control in the stopes was significantly improved, resulting in higher grades processed. Golden Star continued to improve the longhole drilling and blasting productivities during the period and expects the targeted production rate of 650 tpd to be achieved consistently at Prestea Underground during the fourth quarter of 2018.

Prestea reported a cash operating cost per ounce¹ of $1,149 in the second quarter of 2018, which represents a 96% increase compared to the same period in 2017. The increase in cash operating cost per ounce¹ was due primarily to the increase in operating costs from metals inventory and mine operating expenses in the period and the decrease in ounces sold in the second quarter of 2018 compared to the same period in 2017. The cost of sales per ounce¹ at Prestea in the second quarter of 2018 was $1,383.

 

Exploration

Updated Wassa Underground Inferred Mineral Resource Estimate

On April 12, 2018, the Company released an updated Inferred Mineral Resource estimate for Wassa Underground. The updated estimate delivered a 147% increase in Wassa Underground's Inferred Mineral Resources to 5.2 million ounces of gold, in the B Shoot South and F Shoot South areas. The grade of the Inferred Mineral Resources also increased by 9% to 3.6 g/t Au compared to 3.3 g/t Au in the December 31, 2017 estimate.

Further drilling of the Wassa South extensions is underway and the Company expects that Wassa Underground's Inferred Mineral Resources will continue to grow with further step out drilling towards the south. A total of 5,500 metres of drilling was conducted during the second quarter of 2018. Golden Star expects to release the results of this drilling towards the end of the third quarter of 2018.

Golden Star has commenced work on a Preliminary Economic Assessment ("PEA") on the Inferred Mineral Resources of the Wassa Underground deposit. The objective of the PEA is to demonstrate the viability of the Inferred Mineral Resources, potentially including a new access shaft and new ventilation infrastructure. As Golden Star has significant under-utilized capacity in the Wassa processing plant, this additional material could be processed without the need for Golden Star to build any additional processing capacity. Golden Star anticipates that the PEA will be completed in the second half of 2018.

Drilling at Prestea

Golden Star drilled on surface and from underground on the Prestea licence area during the second quarter of 2018, completing a total of 1,870 metres. 

Drilling at Prestea Underground continued to test the Inferred Mineral Resources along the edges of the West Reef ore body with the objective of Mineral Resource expansion. The Company is planning to begin step out drilling to the north of the West Reef in the second half of 2018 to test the potential down plunge extension of the deposit, once drilling chambers have been established.

Drilling at the South Gap target, between the two historic underground shafts (Bondaye and Tuapim), was completed during the second quarter of 2018.  The South Gap is one of the five new potential underground targets that Golden Star outlined in its 2018 exploration strategy.  The Company expects to release the results of the drilling at Prestea Underground and the South Gap during the third quarter of 2018.

FINANCIAL PERFORMANCE

Capital Expenditures

Having largely completed the development of both Wassa Underground and Prestea Underground, capital expenditures for the second quarter of 2018 totaled $10.2 million compared to $18.3 million in the second quarter of 2017, representing a 44% decrease. 77% of capital expenditures were attributable to Wassa ($7.9 million), which included $3.2 million on Wassa Underground capitalized development, $1.9 million on Wassa Underground heavy equipment and replacement components and $1.9 million on exploration drilling. Prestea capital expenditures totaled $2.3 million, which included $1.0 million on the development of Prestea Underground and $0.7 million on exploration drilling.

Second Quarter 2018 Capital Expenditures Breakdown (in millions)

 

Other Financial Highlights

Gold revenues for the second quarter of 2018 totaled $77.1 million from gold sales of 60,559 ounces, at an average realized gold price of $1,273 per ounce.  This figure was consistent with gold revenues in the second quarter of 2017, as increased revenue generated by the Wassa Complex (an increase of 25% compared to the second quarter of 2017) was partially offset by decreased revenue from the Prestea Complex (a decrease of 26% compared to the second quarter of 2017).

Cost of sales excluding depreciation and amortization for the second quarter of 2018 totaled $57.7 million, an increase of 5% compared with the same period in 2017. This was due mainly to an increase in operating costs at Prestea resulting from an increased drawdown of ore stockpiles, partially offset by a decrease in mine operating expenses at Wassa resulting from Wassa transitioning into an underground-only mine.

Depreciation and amortization expenses for the second quarter of 2018 totaled $9.2 million, a 4% increase compared to the second quarter of 2017. This was due to an increase in depreciation at Wassa resulting mainly from an increase in gold production and mining interests, offset partially by a decrease in depreciation at Prestea resulting mainly from lower gold production.

As a result, Golden Star reported a mine operating margin of $10.2 million in the second quarter of 2018, compared to $13.3 million in the second quarter of 2017. This 23% decrease was due primarily to the higher cost of sales in the second quarter of 2018.

General and administrative ("G&A") expenses for the second quarter of 2018 totaled $6.9 million, compared to $2.0 million in the same period in 2017, a 254% increase. The increase in G&A costs for the second quarter of 2018 was due primarily to a $4.5 million increase in share-based compensation expense resulting from an increase in the Company's share price during the quarter, compared to a decrease in the share price during the same period in 2017.

Golden Star recorded a loss of $1.3 million on fair value of financial instruments in the second quarter of 2018, compared to a $4.9 million gain in the same period in 2017.  The $1.3 million fair value loss in the second quarter of 2018 relates to a non-cash revaluation loss on the embedded derivative liability of the 7% Convertible Debentures. The $4.9 million fair value gain recognized in the second quarter of 2017 was comprised of a $4.0 million non-cash revaluation gain on the embedded derivative liability of the 7% Convertible Debentures and a $1.0 million non-cash revaluation gain on the warrants, which were held by Royal Gold, Inc., offset by a $0.1 million non-cash revaluation loss on the 5% Convertible Debentures.

The net loss attributable to Golden Star shareholders in the second quarter of 2018 totaled $6.6 million or $0.02 loss per share (basic), compared to a net income of $13.9 million or $0.04 income per share (basic) in the second quarter of 2017. The net loss in the second quarter of 2018 was due primarily to a decrease of $6.2 million in the gain on fair value of financial instruments, a $5.0 million increase in G&A expenses, a $3.8 million increase in deferred tax expense, a $3.1 million decrease in mine operating margin and a $3.0 million increase in finance expense.

The adjusted net income attributable to Golden Star shareholders¹ in the second quarter of 2018 was $2.4 million, compared to $7.7 million in the same period in 2017. The 69% decrease was due primarily to a lower consolidated mine operating margin and higher net finance, G&A and exploration expenses.

Cash provided by operations before working capital changes¹ in the second quarter of 2018 was $10.3 million compared to $14.2 million in the same period in 2017. This 28% decrease was due primarily to a decrease in consolidated mine operating margin and an increase in exploration and reclamation costs.

The Company's consolidated cash balance was $21.9 million at June 30, 2018.  Working capital provided $0.05 million during the three months ended June 30, 2018, compared to using $3.1 million in the same period in 2017.  The working capital changes in the three months ended June 30, 2018 included a decrease in inventory of $2.8 million, offset by an increase in accounts receivable of $2.1 million, a decrease in accounts payable and accrued liabilities of $0.5 million and an increase in prepaids and other of $0.2 million.

Non-GAAP Financial Measures

In this press release, we use the terms "cash operating cost", "cash operating cost per ounce", "all-in sustaining costs", "all-in sustaining costs per ounce", "adjusted net income attributable to Golden Star shareholders", "adjusted income per share attributable to Golden Star shareholders", "cash provided by operations before working capital changes", and "cash provided by operations before working capital changes per share - basic". 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, severance charges 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" for a period is equal to "cost of sales excluding depreciation and amortization" for the period less royalties, the cash component of metals inventory net realizable value adjustments, materials and supplies write off and severance charges, and "cash operating cost per ounce" is that amount divided by the number of ounces of gold sold (excluding pre-commercial production ounces sold) during the period. We use cash operating cost per ounce as a key operating metric. We monitor this measure monthly, comparing each month's values to prior periods' 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 IFRS. Changes in numerous factors including, but not limited to, 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. We believe 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.

"All-in sustaining costs" commences with cash operating costs and then adds the cash component of metals net realizable value adjustment, royalties, sustaining capital expenditures, corporate general and administrative costs (excluding share-based compensation expenses), and accretion of rehabilitation provision. "All-in sustaining costs per ounce" is that amount divided by the number of ounces of gold sold (excluding pre-commercial production ounces sold) during the period. 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. Share-based compensation expenses are now also excluded from the calculation of all-in sustaining costs as the Company believes that such expenses may not be representative of the actual payout on equity and liability based awards. Share-based compensation expenses were previously included in the calculation of all-in sustaining costs. The Company has presented comparative figures to conform with the computation of all-in sustaining costs as currently calculated by the Company.

The Company believes that "all-in sustaining costs" will better meet the needs of analysts, investors and other stakeholders of the Company in understanding the costs associated with producing gold, understanding the economics of gold mining, assessing the operating performance and also the Company's ability to generate free cash flow from current operations and to generate free cash flow on an overall Company basis. Due to the capital intensive nature of the industry and the long useful lives over which these items are depreciated, there can be a disconnect between net earnings calculated in accordance with IFRS and the amount of free cash flow that is being generated by a mine.

"Cash provided by operations before working capital changes" is calculated by subtracting the "changes in working capital" from "net cash provided by operating activities" as found in the statements of cash flows. "Cash provided by operations before working capital changes per share - basic" is "Cash provided by operations before working capital changes" divided by the basic weighted average number of shares outstanding for the period.

"Adjusted net income attributable to Golden Star shareholders" is calculated by adjusting Net income/(loss) attributable to Golden Star shareholders for (gain)/loss on fair value of financial instruments, share-based compensation expenses, loss on conversion of 7% Convertible Debentures, severance charges and income tax recovery on previously unrecognized deferred tax assets. "Adjusted income per share attributable to Golden Star shareholders" for the period is "Adjusted net income attributable to Golden Star shareholders" divided by the weighted average number of shares outstanding using the basic method of earnings per share.

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. Non-GAAP measures are intended to provide additional information only and do not have standardized definitions under IFRS and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. These measures 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 information under the heading "Non-GAAP Financial Measures" in the Company's Management's Discussion and Analysis of Financial Condition and Results of Operations for the full year ended December 31, 2017, which is 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 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. 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.

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. 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 or in 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.
