The successful blasting of the initial ore from the first stope in the West Reef ore body took place on September 27, 2017.The first stope is being mined using mechanized shrinkage, utilizing Alimak raise climbers, and it will be hauled to surface for processing via the Central Shaft.
Since mid-April 2017 Golden Star has been processing development ore from Prestea Underground and in the second quarter of 2017 the mine delivered its maiden gold production for Golden Star of 325 ounces.
Prestea Underground is expected to achieve commercial production in the fourth quarter of 2017.The mine has Mineral Reserves of 1.09 million tonnes at 13.93 grams per tonne of gold.It is expected to produce 90,000 ounces of gold per annum at a cash operating cost1 of $468 per ounce and an All-In Sustaining Cost1 of $615 per ounce over an initial mine life of 5.5 years.2Exploration drilling is underway at the mine with the objective of increasing the annual production rate and extending the mine life.

Numbers are derived from the Company's Mineral Reserves and Mineral Resources estimate as of December 31, 2016 and the technical report entitled "NI 43-101 Technical Report on a Feasibility Study of the Prestea Underground Gold Project in Ghana", effective November 3, 2015, filed under the Company's profile on SEDAR at www.sedar.com.
Sam Coetzer, President and Chief Executive Officer of Golden Star, commented:
"I am delighted to announce that stoping has commenced at Prestea Underground.We believe that this is the first time that a production stope has been blasted since 2001 and it is a historical achievement for both Golden Star and the Prestea community in Ghana. I would like to thank Martin Raffield, our SVP of Project Development & Technical Services, Jerry Agala, the General Manager of the Prestea mine, and the development team for all of their hard work and dedication in transforming a century old mine to a completely modern mine.I would also like to thank our Chief Operating Officer, Daniel Owiredu, and the operations team for their commitment to achieving this important milestone.The development of the next four stopes is progressing well and we are on track to achieve commercial production in the fourth quarter of 2017. Prestea Underground is one of Golden Star's two cornerstone mines and we will continue to build upon the momentum within the Company to deliver a sustainable, mid-tier gold producer."

Non-GAAP Financial Measures
In this press release, we use the terms "cash operating cost per ounce" and "All-In Sustaining Cost".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.
"Cash operating cost per ounce" 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 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 excluding non-cash share based compensation, 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.Non-cash share-based compensation expenses are now also excluded from the Company's current method of calculating All-In Sustaining Costs, as the Company believes that such expenses may not be representative of the actual payout on the equity and liability based awards. Non-cash 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.
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 are 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.
