George Town, March 13, 2018 - Endeavour Mining (TSX:EDV) (OTCQX:EDVMF) is pleased to announce its financial and operating results for the fourth quarter and full year 2017, with highlights provided in the table below.

Table 1: Key Operational and Financial Highlights

¹This is a non-GAAP measure. Refer to the non-GAAP measure section of the MD&A. ²Realized Gold Price inclusive of Karma stream; ³Realized Gold Price less AISC per ounce; ⁴Net revenue less All-in Sustaining Cost; ⁵Net revenue less All-in Sustaining Costs and Non-Sustaining capital; ⁶Adjusted EBITDA divided by Revenues.

Sébastien de Montessus, President & CEO, stated: "2017 was yet another strong year for Endeavour. We delivered against all key performance metrics, achieving record production of 663koz, up 12% over 2016, while continuing to successfully reduce our costs. Importantly, we were able to significantly increase our operating cash flow with the start-up of our flagship Houndé mine in the fourth quarter, which we commissioned ahead of schedule and under budget. We also continued to improve our portfolio quality with the sale of our non-core Nzema mine and the purchase of the Kalana project. 

2018 will be a year in which we continue to build on our strengths and achievements, with the construction of our Ity CIL project progressing on track and on budget and an updated feasibility study planned for Kalana later this year. Our aggressive exploration efforts will also continue as we aim to develop more greenfield projects to secure our longer-term growth pipeline. This year our focus on operational excellence and active portfolio management will continue, with a strategic decision regarding our Tabakoto mine to be made later in the year.

Overall, I am very pleased with our strong performance and would like to thank our entire team for their dedication, focus and excellent delivery, as well as the Board for their support. 2018 will be a key year as we continue our transformation towards achieving our 2019 objective of annual gold production of above 800koz at below $800/oz AISC."

2017 KEY ACHIEVEMENTS AND 2018 CATALYSTS

In 2017, Endeavour continued to deliver against its strategy, with good progress made across its 4 strategic levers:

1. Operational excellence - reinforced track record as Group Lost Time Injury Frequency Rate decreased from 0.40 to 0.29 year on year, remaining below industry benchmarks. Production and AISC guidance met for the 5^th consecutive year.
2. Project development - remained a key focus in 2017 with the successful completion of the Houndé construction in October and the Karma plant optimization in November, as well as the launch of Ity CIL construction in September.
3. Exploration - continued focus in 2017 with the priority being to increase Ity's Indicated resources to adequately size the plant, which successfully led to the addition of over 1 million ounces and an updated Optimization Study based on a 4Mtpa plant, up from 3Mtpa in the 2016 feasibility. Additional notable successes were the confirmation of high-grade mineralization at several targets near the Houndé plant (which will be a large focus for 2018), further discoveries at Ity, the launch of an exploration JV with Randgold in Ivory Coast, and the consolidation of greenfield exploration tenements.
4. Active portfolio and balance sheet management - In line with its aim to focus on high quality assets, following the sale of its non-core Youga mine in 2016, in 2017 Endeavour sold its non-core Nzema mine in Ghana (due to its short mine life, low exploration potential and high AISC) and strengthened its project pipeline with the purchase of the Kalana project (low AISC, long life, high exploration potential and attractive equity IRR). On the balance sheet front, Endeavour negotiated better terms for its revolving credit facility in 2017, remaining well-funded to push forward its growth pipeline.

2018 is expected to be another pivotal year for Endeavour with the following notable catalysts:

• Production expected to increase to 670 - 720koz and AISC to decline to $840 - 890/oz with the full-year benefit of Houndé.
• Project development is expected to remain a strong focus with the ongoing Ity CIL project construction (which is tracking on-budget and on-time for first gold pour by mid-2019) while an updated feasibility study is expected for the Kalana project by year-end.
• Exploration will continue to be a strong focus in 2018 with a company-wide exploration program of between $40-45 million with the main focus being near-mine exploration at Houndé, conducting an intensive exploration campaign at Kalana during H1-2018 (with the aim of publishing an updated resource by mid-year), continuing to build on Ity's exploration success, and ramping up greenfield exploration which represents 40% of the 2018 budget.
• Endeavour intends to continue to actively manage its portfolio with a strategic decision on Tabakoto expected mid-2018.

STRONG Q4 PERFORMANCE; FULL YEAR GUIDANCE ACHIEVED

• Q4-2017 group production increased by 38% over the previous quarter to 204koz and AISC declined by 13% to $785/oz due to the successful start-up and out-performance of Houndé while the other mines in aggregate performed in-line with expectations.
• Full-year 2017 group production increased by 12% over the prior year to 663koz, attaining the top half of its 630-675koz guidance while AISC decreased by $17/oz to $869/oz ending well within the guidance range of $850-895/oz.
• The Nzema sale closed on December 29, 2017 and has been deconsolidated in the year-end financial statements.

 HOUNDÉ MINE

 Construction Insights

• No Lost-Time-Injury occurred over the 7-million man hours worked during the construction period.
• Construction completed ahead of schedule and $15 million below the initial capital budget of $328 million. As construction was tracking ahead of schedule and below budget, Endeavour decided to spend approximately $21 million in addition to the initially planned works (mainly for a 26MW back-up power station and fuel farm and to build a second tailings storage facility), bringing the total investment to $334 million.
• Achieved first gold pour on October 18, 2017.
• Nameplate capacity was achieved within weeks following the introduction of ore, by the end of October 2017.
• Following the rapid ramp-up period, commercial production was declared on November 1, 2017 more than two months ahead of schedule (all ounces sold were considered as commercial production and included into the AISC).

 Q4 Insights

• Production totalled 69koz since the start of mining operations; significantly surpassing the upper end of the 30-35koz guidance, due to better than expected mill availability, throughput, grades and recovery rates.
• AISC amounted to $335/oz, significantly below the lower end of the $550-600/oz forecast due to the aforementioned greater than expected production and lower mining costs.
• Unit costs compare very favourably to metrics presented in the optimized feasibility study.

Table 4: Houndé Performance Indicators

 2018 Outlook

• Houndé is expected to produce 250-260koz in 2018 at an AISC of $580-630/oz.
• Mining activities are expected to continue to ramp-up to achieve a mining rate of 40Mtpa, up from 18Mtpa in 2017.
• Mining and processing of fresh ore began in the latter portion of Q4-2017. Mining activities are expected to progressively transition from mainly oxides in early 2018 to mainly fresh ore by the end of 2018.
• Nearly $23 million of non-sustaining expenditure is planned for 2018, primarily for waste capitalization and resettlement for the Bouere and Dohoun deposits.
• Of the initial total project spend of $334 million, $10 million (related mainly to billing timing and the second tailings storage facility) is expected to be spent in 2018. As shown in Table 23 of the guidance section below, this amount is classified as Growth Capital. 

 2017 Exploration Program

• Following a two-year period of no exploration, activities resumed in 2017 with $5 million spent on a drilling program totalling approximately 76,000 meters.
• The 2017 campaign yielded positive results with the discovery of high-grade intercepts at both the Kari Pump target and the Sia/Sianikoui targets.

 2018 Exploration Program

• In 2018, Houndé will be the strongest focus for Endeavour with a $9 million exploration program totaling approximately 125,000 meters planned with the aim of drilling the entire Kari anomaly and delineating a maiden resource.

 Reserve & Resource Evolution 

• As shown in appendix 3, the variance in P&P reserves and M&I resources compared to the previous year is due primarily to mining depletion at the Vindaloo deposit which demonstrated good reconciliation to the resource model.
• Ahead of mining the Bouere deposit in 2019, a short in-fill drilling program was conducted in 2017 which resulted in a more conservative grade estimate. Both the reserves and resources decreased by approximately 30koz to 148koz of P&P reserves and 161koz of M&I resources.  

 AGBAOU MINE

 Q4  vs Q3-2017 Insights

• Production decreased in line with guidance, mainly due to a lower grade and slightly lower tonnage milled.
  • Ore extraction continued to perform well, with tonnage flat over the previous quarter.
  • Mill throughput decreased slightly but remained at a high level as the proportion of fresh ore processed increased from 15% to 25%.
  • Processed grades decreased due to the mining sequence.
  • Recovery rates remained constant despite a greater proportion of fresh ore.

• All-in sustaining costs increased in line with guidance as operations continued to transition towards mining and processing a greater proportion of fresh ore.
  • Mining costs remained flat at $2.68/t.
  • Processing costs increased from $7.08/t to $8.07/t due to increased reagent consumption associated with the greater proportion of fresh ore processed.
  • Sustaining capital costs decreased by 46% due to land compensation incurred in Q3-2017.

 Full Year 2017 Insights

• Total production in 2017 was 177koz, achieving the mid-range of the 175-180koz guidance. As expected, production decreased after the record 2016 performance of 196koz as the mine began to transition to harder material.
• AISC for 2017 amounted to $647/oz, well below the guided $660-700/oz range, as less fresh and transitional ore was processed than initially planned. In addition, lower than anticipated sustaining capital was incurred as planned waste capitalization was pushed into 2018.

Table 5: Agbaou Quarterly Performance Indicators

Table 6: Agbaou Yearly Performance Indicators

 2018 Outlook

• 2018 is expected to be a transition year for Agbaou with a large focus on waste capitalization activities (including the pre-strip on the West pit), which are expected to give access to higher grade areas afterwards.
• Agbaou's 2018 production is therefore expected to decrease to 140-150koz as low-grade stockpile feed is expected to supplement mine feed to allow waste capitalization activities to progress more quickly.
• The ore process blend is expected to average 50% oxide and 50% fresh and transitional ore throughout the year.
• AISC is expected to increase to $860-$900/oz as a result of increased mining costs (deeper pits, longer haul distances, and increased drill and blast activities related to hard ore) and higher processing costs (lower throughput and higher consumption ratios linked to the mineralogy of the ore). In addition, the sustaining cost is expected to increase due to the greater waste capitalization.

 2017 Exploration Program

• Agbaou's 2017 exploration program amounted to $6 million, totaling 31,400 meters of drilling.
• The primary objective for the 2017 program was to conduct in-pit drilling at the North pit and to test gold in soil anomalies on parallel shear zones. The latter marks the first target generation campaign since production began in 2014, as exploration activities were previously mainly focused on in-pit and step-out drilling due to capital constraints.
• The campaign at the North pit confirmed that its mineralization extends at-depth with occurrences of higher grade intercepts. A further drilling campaign is planned for 2018 with the aim of delineating a resource. 
• The intercepts obtained from the initial parallel shear zone targets drilled demonstrated insignificant thickness and continuity. It is thought that perhaps the northern extension of the known deposits may have been displaced through a dextral structural corridor, which will be further investigated during the 2018 exploration campaign.

 2018 Exploration Program

• A $4 million exploration program totaling approximately 16,000 meters has been planned for 2018 with the aim of delineating the at-depth potential of the North pit and further investigating targets on parallel trends.

 Reserve & Resource Evolution 

• Given the main focus for the 2017 exploration program was to generate and test targets, as shown in Appendix 3, the variance in P&P reserves and M&I resources compared to the previous year mainly corresponds to mining depletion.

 KARMA MINE

 Q4 vs Q3-2017 Insights

• Production remained flat as higher stacking capacity and grades were offset by the anticipated lower recovery rate.
  • Ore tonnage extraction significantly increased due to the end of the rainy season, a lower strip ratio, and in response to greater stacking capabilities. 
  • Stacking increased following the successful commissioning of the new front-end and ADR plant, while Q3 2017 was impacted by downtime associated with the commissioning of the upgraded crushing circuit and decommissioning of the original circuit.
  • Higher-grade transitional ore from Rambo was strategically mined and stacked once the plant optimization was completed to benefit from greater stacking capacity to offset its lower recovery rate. The Rambo pit was mined out during the quarter.
  • Stacked grade increased in Q4-2017 due to high-grade ore from the Rambo deposit, while low grade stockpiles supplemented feed in Q3-2017.
  • Recovery rates decreased as anticipated due to the stacking of greater amounts of transitional ore from the Rambo deposit.

• AISC decreased because of the higher grades, lower strip ratio, and lower stacking unit costs which offset the higher mining unit costs associated with extracting Rambo transitional ore and the impact of lower recovery rates. Following the completion of the optimization project in November, AISC decreased below $850/oz in December and are expected to trend lower. 
  • Mining costs remained constant at $1.75/t as higher mining cost associated with the transitional ore at Rambo was offset by lower mining costs associated with the oxide ore at GG2.
  • Processing costs decreased from $11.25 to $8.15/t milled due to increased tonnes stacked in Q4-2017 in connection with the commissioning of the new front-end crusher.
  • Sustaining capital costs decreased by 38% due to a decrease in capital stripping costs.

 Full Year 2017 Insights

• Production totalled 98koz in 2017, near the lower-end of the 100-110koz guidance. The increase compared to 2016 is due to 2017 benefitting from a full year of production.
• AISC for 2017 amounted to $834/oz, above the guided $750-800/oz, mainly due to lower than expected production.

Table 7: Karma Quarterly Performance Indicators

Table 8: Karma Yearly Performance Indicators

 2018 Outlook

• Plant optimization work was successfully carried out during 2017. The newly installed front-end and ADR plant are expected to boost stacking capacity beyond the initial design capacity of 4Mtpa.
• Production in 2018 is expected to increase to 105-115koz and AISC is expected to decrease to $780-830/oz as a result of the plant optimization work done in 2017.
• Mining activities are expected to focus on the GG2 and Kao deposits. The remaining ore from the GG2 deposit is mainly transitional material as the deposit is expected to be mined out in Q2 2018. Mining at the Kao deposit is scheduled to start in Q1 2018 with oxide ore mined throughout the year. In the latter portion of the year, pre-stripping is expected to be done at the North Kao deposit.
• In aggregate, roughly 15% of the 2018 ore feed is expected to be transitional material from GG2. As such, recovery rates are expected to be lower in the first half of 2018 and then increase in the second half as mining activities are expected to focus mainly on oxide ore from the Kao deposit.
• Nearly $23 million of non-sustaining capital is planned for 2018, mainly for the Kao resettlement, pre-stripping at Kao and North Kao and a heap leach lift.

 2017 Exploration Program

• Karma's 2017 exploration program amounted to $3 million, totalling 41,520 meters of drilling focused primarily on the northeast extension of the North Kao deposit and on the Yabonsgo target.
• Drilling at the North Kao deposit extension confirmed the deposit's continuity, which resulted in the delineation of 19koz of M&I resources and 51koz of Inferred resources.
• Drilling at the Yabonsgo target resulted in the delineation of 65koz of Inferred resources, which are expected to be converted into Indicated resources in 2018.
• In addition, 6koz of M&I resources and 6koz of Inferred resources were delineated at the Rambo West deposit.

 2018 Exploration Program

• A $2 million exploration program totalling approximately 32,000 meters has been planned for 2018 with the aim of delineating Indicated resources at both North Kao and Yabonsgo, in addition to near-mill targets such as Rounga and on the recently acquired Zanna exploration license.

 Reserve & Resource Evolution

• As shown in Appendix 3, P&P reserves decreased in line with mine depletion, while M&I resources decreased to a lesser extent due to the additions at North Kao and Rambo West.

 ITY MINE: HEAP LEACH OPERATION

 Q4 vs Q3-2017 Insights

• Following the rainy season, production increased due to higher stacking and mining rates, in addition to improved grades and recovery rates.
  • Tonnes of ore mined increased as mining activities ramped up following the end of the rainy season. Mining continued on the Zia and Ity Flat pits in Q4, following the decision to defer the high-grade Bakatouo pit for the upcoming CIL project.
  • Ore stacked increased due to the softer nature of the Ity Flat laterite ore and the benefit of the dry season.
  • The stacked grade increased as higher-grade ore at the Ity Flat pit became accessible.
  • Recovery rates increased but were still impacted by the lag-time of the highly soluble copper content of the Bakatouo ore stacked in Q3-2017.  

• AISC decreased due to lower unit mining costs (associated with reduced water pumping requirements) and lower unit processing costs (due to higher stacking rates and reduced cyanide consumption associated with the high soluble copper ore stacked in Q3-2017). Despite these unit cost reductions, AISC remained high due to sustaining capital expenditures related to fleet upgrades. 
  • Mining costs decreased from $5.16 to $3.27/t as mining volumes increased following the end of the rainy season.
  • Processing costs decreased from $14.75 to $13.85/t due to higher tonnes stacked in Q4-2017 along with lower cyanide consumption associated with the ore previously stacked from the Bakatouo deposit.
  • Sustaining capital costs increased by 52% due to critical spares purchased in the quarter.

 Full Year 2017 Insights

• As previously indicated, full year production came in below the guided 75-80koz range at 59koz and AISC exceeded the guided $740-780/oz range at $906/oz due to the shift away from mining the higher grade Bakatouo deposit planned in H2-2017.
• Production and AISC were impacted as mining shifted to lower grade deposits and the recovery rates returned to more normalized levels. In addition, AISC was impacted by higher sustaining costs on a per ounce basis.

Table 9: Ity Quarterly Performance Indicators

Table 10: Ity Yearly Performance Indicators

 2018 Outlook

• Production in 2018 is expected to increase slightly to 60-65koz and AISC are expected to decrease to $790-$850/oz as a result of anticipated higher grades.
• 2018 is expected to be a transition year for the heap leach operation with greater priority given to the CIL construction activities and the maximizing of trade-off opportunities between immediate heap leach production and better margins with the CIL plant, with planned lower costs and higher recovery rates in 2019. 
• A specific mining strategy has been set to address both the needs of the heap leach operation and the CIL project.
  • Open pit mining activities for the heap leach operation are expected to occur only during the first half of 2018. The aim is to intensify mining at the Zia and Mont Ity deposits to create a stockpile sufficient to feed stacking requirements for the second half of the year. During this time, some selected mined ore types are expected to be stockpiled for the CIL operation.
  • In the second half of the year, greater mining focus will be given to the CIL project. 
• As a result of this strategy, heap leach production is expected to be lower in the second half of the year while AISC are expected to be higher.

 2017 Exploration Program

• Ity's 2017 exploration program amounted to $8 million, totaling 58,500 meters of drilling focused on increasing the resource base for the CIL Optimization Study published in September 2017.
• More than 1 Moz of Indicated resources were added in 2017 following the successful drilling campaigns at the Bakatouo, Ity, Daapleu and Verse Ouest deposits and at the recent Le Plaque discovery.
• As announced on February 22, 2018, a maiden resource (85koz of Indicated and 43koz of Inferred) was defined for an area that represents about 25% of the Le Plaque target. 

 2018 Exploration Program

• A $3 million exploration campaign has been planned to further explore near-mill targets (including testing of extensions at the Mont Ity, Bakatouo, Daapleu, Le Plaque deposits) with the aim of delineating additional resources for the CIL project.
• Given the CIL project already has a robust mine life, 2018 will see more focus dedicated to greenfield targets within the 100km corridor along the Ity mine, with a $5 million exploration campaign planned.  

 Reserve & Resource Evolution 

• As shown in Appendix 3, P&P reserves increased as a result of M&I resources increasing by over 1 million ounces due to the aforementioned exploration success and the publication of the CIL Optimization Study in September 2017.

 TABAKOTO MINE

 Q4 vs Q3-2017 Insights

• Production decreased mainly due to lower average head grades, in spite of overall improved mining operations.
  • Open pit production at Kofi B and Tabakoto North was significantly increased following the end of the rainy season, however at a lower grade as the higher-grade Kofi C deposit was depleted in Q3.
  • Underground tonnes mined decreased as Q4-2017 was impacted by low equipment availability.
  • Processing activities continued to perform well, with throughput increased to partially offset lower grades.
  • The overall average grade decreased mainly due to lower open pit grades and the use of lower grade stockpiles. 
  • The recovery rate decreased slightly due to lower grades milled and the compromise to increase the throughput rate.

• AISC increased despite decreases across all unit costs per tonne (open pit and underground mining, processing, and G&A), which were offset by higher sustaining costs and lower grades.
  • Open pit mining costs decreased from $3.91 per to $2.99/t due to the volume effect of tonnes mined after the end of the rainy season.
  • Underground mining costs slightly decreased from $75.79 to $74.90/t, remaining however high due to low equipment availability and high associated maintenance costs.
  • Processing costs decreased from $20.83 to $20.22/t as cyanide and lime consumption was reduced to interact with the characteristics of the ore blend processed.
  • Sustaining capital costs increased by 48% due to increased underground development at Tabakoto and Segala underground after the end of the rainy season.

 Full-Year 2017 Insights

• Production totaled 144koz in 2017, below the 150-160koz guidance range, mainly due to a lower open pit grade following the depletion of the high-grade Kofi C deposit.
• AISC finished above the $950-990/oz guidance range at $1,148/oz, mainly due to sub-optimal underground equipment availability and several national strikes.

Table 11: Tabakoto Quarterly Performance Indicators

Table 12: Tabakoto Yearly Performance Indicators

 2018 Outlook

• Tabakoto production is expected to decrease to 115-130koz from both the underground mines (Segala and Tabakoto) and open pits (Kofi B, Tabakoto North and Baboto), mainly due to a decline in average grade.
• AISC are forecast to increase to $1,200-$1,250/oz due to the aforementioned lower grade and a circa 75% increase in sustaining capital expenditures to $35 million for the replacement of mining equipment, plant maintenance and underground capital development.
• n line with Endeavour's portfolio management strategy, a strategic assessment is expected to be made on Tabakoto during the course of the year.

 2017 Exploration Program

• Tabakoto's 2017 exploration program amounted to $8 million, totaling 56,200 meters focused on both underground resource delineation and testing near-mill open pit targets.
• Successful exploration resulted in increased underground M&I resources by 123koz (net of depletion) while reserves increased by 44koz (net of depletion) as depleted ounces were replaced and a portion of the new M&I resources were converted. In addition, the underground exploration programs confirmed the discovery of new vein sets that will be further delineated in 2018.
• Near-mill exploration confirmed the mineralization at both the Kreko and Fougala targets. However, both targets appear to be of small scale as an aggregate maiden Indicated resource of 50koz was delineated. Other near-mill targets are expected to be explored in 2018.

 2018 Exploration Program

• A $7 million exploration program totalling approximately 45,000 meters has been planned for 2018, equally allocated on near-mill targets (both underground and open pit) and on greenfield targets on both the Kofi permit and on the new permits acquired in 2017 located immediately north of Kofi and on-trend with Randgold's Loulo deposits.

 Reserve & Resource Evolution 

• As shown in appendix 3, total P&P reserves decreased over the previous year, net of depletion, as open pit reserves were not replaced while underground reserves grew. M&I resources (net of depletion) grew due to the aforementioned underground exploration success and resources added at both the Kreko and Fougala targets.

 NZEMA MINE

 Nzema Sale Insights

• On December 29, 2017, Endeavour completed the sale of its 90% interest in its non-core Nzema Mine in Ghana to BCM International Ltd ("BCM").
• Endeavour received a payment of $38.5 million upon closing, corresponding to the first two payments less adjustments. Additional deferred payments of up to $25 million are expected to be received over the course of 2018 and 2019, based upon the attainment of certain agreed milestones related to mine free cash flow generation.

 Q4 vs Q3-2017 Insights

• Production decreased as expected due to lower processed grades for both mined and purchased ore.
  • As expected, tonnes of ore mined increased following the end of the rainy season.
  • Purchased ore grades decreased to a more normal level after a peak in Q3.
  • Mill throughput continued to increase as the first half of the year was impacted by a higher proportion of fresh ore processed.
  • The head grade decreased for both Endeavour's own mined ore (following a peak immediately after completing the cut-back in Q3-2017) and purchased ores.
  • Recovery rates remained constant.

• AISC increased mainly due to lower grades and subsequent decreased production, which was partially offset by decreased mining and processing costs per tonne. 
  • Mining costs decreased from $6.20 to $5.49/t  mainly due to shorter load and haul distances.
  • Processing costs decreased from $17.00 to $16.08 per tonne milled due to a decrease in power and water treatment costs incurred in Q3-2017.
  • Sustaining capital decreased by 80% as sustaining capital expenditures were limited to predominantly capitalised stripping costs given the expenditure on the tailings storage facility was completed in Q3-2017.

 Full Year 2017 Insights

• Production totalled 116koz in 2017, surpassing the upper-end of the 100-110koz guidance range.
• AISC amounted to $859/oz, coming in below the guided $895-940/oz range due to strong efforts to reduce costs and improve purchased ore quality.
• As expected, the production and AISC profile significantly improved compared to 2016, benefitting from completing the push-back which gave access to higher-grade material ore. In addition, purchased ore grades improved in 2017 following the implementation of quality control procedures.

Figure 1: Ity CIL Construction Milestones

 KALANA PROJECT UPDATE

• In Q4-2017, Endeavour completed the integration of Avnel and initiated pre-development activities to optimize the Kalana Project, which include: 
  • Ceasing the current small-scale operations and clearing the underground workings and existing infrastructure to allow for the development of future open pits, as well as to establish access for exploration.
  • Resuming exploration activities on both the Kalana deposit and nearby targets including Kalanako with the goal of publishing an updated resource statement by mid-2018.
  • Launching a revised Feasibility Study, which is expected by the end of 2018, with the goal of increasing the current plant design capacity to lift the average annual production and shorten the mine life based on current reserves, integrating the exploration results from the upcoming drilling campaign, and leveraging Endeavour's construction expertise and realized operating synergies.
  •  Dedicated Kalana Project Community Relations and HSE teams were created to validate the census and stakeholder mapping, with the aim of defining a resettlement action plan before relocation activities commence.

2018 Exploration Activities

• For 2018, a $5 million exploration program has been planned, with the objective of completing 45,000 meters in H1-2018 to provide by mid-year an updated resource which is expected to form the basis for the feasibility study.
• Exploration is focused on infill and extension drilling the Kalana deposit, as well as further drilling the previously discovered Kalanako deposit.
• Additional exploration is also expected to take place on the recently acquired Fougadian license and on permits which are expected to be granted shortly.

EXPLORATION ACTIVITIES

2017 Exploration Activities

• As shown in Table 15, a total of $44 million of exploration expenditures were incurred in 2017.
• The strongest focus of the 2017 exploration program was to increase Ity's Indicated resources for inclusion in the Optimization Study published in September 2017, which successfully led to the addition of over 1 million ounces. 
• Further details of the completed exploration programs have been provided within the above mine sections.

Table 15: Exploration Guidance, $m

*Includes expensed, sustaining, and non-sustaining exploration expenditures

2018 Exploration Activities

• Exploration will continue to be a strong focus in 2018 with a company-wide exploration program of $40-45 million (approximately 15% expensed, 15% sustaining, 70% non-sustaining), compared to circa $44 million in 2017, with details by asset provided in the above mine sections.
• Houndé and Kalana are expected to be the largest near-mine focus during 2018. 
  • A 125,000 meter program is planned at Houndé to support the ramp-up of mining operations and to notably follow-up on the Kari discovery announced in late-2017.
  • A 45,000 meter intensive drilling campaign is planned at Kalana for H1-2018 with the aim of publishing an updated resource by mid-year, which will then form the basis for the updated feasibility study. 
• Approximately 40% of the budget (representing approximately $16 million) is expected to be dedicated to greenfield opportunities, in line with the overall strategy of sourcing Endeavour's next mine organically.
  • Primary focus will be on Côte d'Ivoire regional exploration licenses which include Fetekro, the Bondoukou cluster, and the Mankono-Sissedougou JV with Randgold.
  • Initial drilling campaigns will also be conducted on greenfield targets located along the 100km trend along the Ity mine.
  • A drilling campaign will also be initiated on a few targets located in the northern part of the Kofi exploration permit, which are located on the same structural trend as the Loulo deposits.

GROUP RESERVES AND RESOURCES

• Proven and Probable (P&P) reserves at year-end 2017 were 9.1Moz, which increased by 2.0Moz (+29%) compared to 7.1Moz at the end of 2016 mainly due to the reserve conversion at Ity, the purchase of Avnel which offset the sale of Nzema and reserve depletion at other mines.
• Measured and Indicated ("M&I") resources at year-end 2017 were 14.9Moz, which increased by 2.3Moz (+18%) compared to 12.6Moz at the end of 2016 mainly due to strong exploration success at Ity, the purchase of Avnel and net additions at Tabakoto, which offset reserve depletion at other mines and the sale of Nzema.
• Detailed year-over-year reserve and resource variances are available in Appendix 3 with details for each asset provided in the above mine sections.

INCREASED CASH FLOW GENERATION

• 2017 gold sales from continuing operations totaled 537koz, up from 460koz in 2016, mainly due to a full year of production at the Karma mine following its start in Q2-2017 and the successful start-up of Houndé.
• The 2017 realized gold price was $1,214/oz (net of the impact of the Karma stream) compared to $1,231/oz in 2016.
• The Group's 2018 All-In Sustaining Margin (inclusive of discontinued operations) increased from $192 million to $231 million due primarily to the increased Karma production and the successful start-up of Houndé which more than offset a lower realized gold price and the expected AISC/oz increase at Agbaou.
• Non-sustaining capital spending increased from $26 million in 2017 to $44 million with the main investment occurring at Karma (total of $25 million for a heap leach pad expansion, relocation, and pre-stripping activities) and Nzema ($9 million for the Adamus pit push-back), while non-sustaining exploration spending increased from $17 million to $25 million.
• The All-In Margin increased by 9% in 2017 compared to 2016, despite the aforementioned increased non-sustaining expenditures, while the Net Free Cash Flow from Operations increased by 70% to $107 million as 2016 was impacted by cash settlements on hedge programs, and 2017 benefited from an improvement in the working capital variation and lower financing costs (due to better terms negotiated).
• 2017 had a net cash variation of negative $162 million mainly due to the expected $317 million growth project spend and a $42 million outflow for M&A activities, which were partially offset by net equity proceeds. 

Table 17: Simplified Cash Flow Statement

¹Comprised of $196 million for Houndé construction, $70 million for Ity CIL construction, $41 million for Karma optimization, and $4 million for Kalana project. Certain line items in the table above are NON-GAAP measures. For more information and notes, please consult the Company's MD&A.

NET CASHFLOW, NET DEBT AND LIQUIDITY SOURCES

• Net cash flow from operating activities for 2017 was $222 million, up $68 million over the prior year mainly due to a full year production at the Karma mine following its start in Q2-2016 and the successful start-up of Houndé in Q4-2017 which more than offset the lower realized gold price and the expected cost increase at Agbaou.
• Net cash used in investing activities during 2017 was $479 million, which included $317 million of growth project capital (as described in the above section), $54 million for the purchase of an additional 25% stake in the Ity mine, and $114 million in sustaining and non-sustaining capital for continuing operations. These were partially offset by the $9 million net cash received from the sale of Nzema ($38.5 million received on closing less deconsolidation of $30 million Nzema cash position) and by the $8 million inflow of cash acquired upon the Avnel acquisition.
• Net cash generated in financing activities for 2017 was $252 million, which included $160 million on the Revolving Credit Facility ("RCF") for the construction of the Houndé project and $113 million of equity proceeds.
• Equipment finance leasing stood at $54 million as at December 31, 2017, up over the previous year due to Houndé mining equipment and backup power generators.  
• As anticipated, net debt increased from $26 million to $232 million over the past year due to the Houndé construction, with the Net Debt / Adjusted EBITDA (LTM) ratio remaining healthy at 1.05x.   
• At year-end, Endeavour's available sources of financing and liquidity totaled $323 million which included its $123 million cash position and $200 million undrawn on the revolving credit facility. Following the quarter-end, Endeavour issued a $330 million convertible note with the intent of downsizing its $500 million revolving credit facility to $350 million, thereby further increasing its liquidity sources by $180 million to $503 million, remaining well positioned to fund its growth. In addition to the aforementioned liquidity sources, Endeavour also has strong cash flow generation, upcoming equipment financing of approximately $60 million for its Ity CIL Project, and remaining proceeds from the Nzema sale.

   OPERATING CASH FLOW PER SHARE

• Due to the start-up of Houndé in Q4-2017, the quarter's operating cash flow before non-cash working capital increased by 157% over Q3-2017 to $95 million, representing $0.89/share.
• The 2017 operating cash flow before non-cash working capital increased by 24% over the prior year to $235 million, representing $2.39/share (relatively flat over the previous year due to increased share count).

Operating Cash Flow Per Share is a NON-GAAP measure. For a discussion regarding the company's use of NON-GAAP Measures, please see "note regarding certain measures of performance" in the MD&A.

ADJUSTED NET EARNINGS PER SHARE  

• Adjusted net earnings from continuing operations amounted to $69 million for 2017, a decrease of $50 million over 2016, mainly due to a $45 million increase in depreciation.
• In 2017, total adjustments of $247 million were made related mainly to:
  • A $130 million impairment charge on Tabakoto, decreasing its carrying value to $94 million. As guided, a strategic decision on Tabakoto is expected by mid-year.  
  • A $44 million net loss on the sale of Nzema
  • In addition, adjustments were notably made for acquisitions and restructuring costs, deferred income tax expense, stock-based expenses, gains/loss on financial instruments and other non-cash adjustments.

Adjusted Net Earnings is a NON-GAAP measure. For a discussion regarding the company's use of NON-GAAP Measures, please see "Note Regarding Certain Measures of Performance" in the MD&A.

2018 OUTLOOK

• Production from continuing operations is expected to increase to 670-720koz in 2018 and AISC is expected to decrease to $840-890/oz due to the full year benefit of Houndé and improvements at Karma and Ity which are expected to more than offset declines at Agbaou and Tabakoto. More details on individual mine guidance have been provided in the above sections.
• In line with Endeavour's portfolio management strategy, a strategic assessment is expected to be made on Tabakoto during the course of the year. As shown in the below tables, 2018 production excluding Tabakoto is expected to range between 555-590koz at an AISC of $760-810/oz.

Table 21: Production Guidance, koz

*Nzema has been deconsolidated

* Nzema has been deconsolidated

• As detailed in the table below, sustaining and non-sustaining capital allocations for 2018 amount to $68 million and $84 million respectively. Growth projects amount to $200 million, mainly for the Ity CIL project construction.

Table 23: Capital Expenditure Guidance, $m

• Endeavour's objective is to fund as much as possible of the Ity CIL construction costs using the free cash flow generated over the construction period, rather than accessing its Revolving Credit Facility ("RCF"). To support this funding approach it has put in place a short-term Gold Revenue Protection Strategy consisting of Gold Option Contracts, in line with the strategy employed during the Houndé construction.
  • A deferred premium collar strategy using written call options and bought put options has been put in place beginning on February, 1, 2018 and ending on April 30, 2019 with a floor price of $1,300/oz and a ceiling price of $1,500/oz. The program covers a total of 400,000 ounces, representing approximately 40% of Endeavour's total estimated gold production for the period. The total premium payable for entering into this program was $8.7 million, which is deferred and settled as monthly contracts mature. 
  • The advantages of the Gold Option Contacts during the construction period include:
    • ~40% of production will be protected if the gold price falls below $1,300/oz
    • 100% of production will benefit from gold price upswings between $1,300 and $1,500/oz
    • ~60% of production benefits from gold price upswings beyond $1,500/oz
    • Once the Gold Option Contracts program ends, Endeavour will return to a position where its gold production is fully exposed to spot gold prices.

ABOUT ENDEAVOUR MINING CORPORATION

Endeavour Mining is a TSX listed intermediate African gold producer with a solid track record of operational excellence, project development and exploration in the highly prospective Birimian greenstone belt in West Africa. Endeavour is focused on offering both near-term and long-term growth opportunities with its project pipeline and its exploration strategy, while generating immediate cash flow from its operations.

Endeavour operates 5 mines across Côte d'Ivoire (Agbaou and Ity), Burkina Faso (Houndé, Karma), and Mali (Tabakoto) which are expected to produce 670-720koz in 2018 at an AISC of $840-890/oz. Endeavour's high-quality development projects (recently commissioned Houndé, Ity CIL and Kalana) have the combined potential to deliver an additional 600koz per year at an AISC well below $700/oz between 2018 and 2020. In addition, its exploration program aims to discover 10-15Moz of gold by 2021 which represents more than twice the reserve depletion during the period.
